U.S. Central Plains and Southwest will likely face apocalyptic drought
(02/12/2015) In the recent film Interstellar, a mysterious phenomenon known as "the blight" is wiping out agriculture around the world until only corn—for some reason—survives. Humanity is on the brink of starvation. While the blight may be science fiction, global warming is not, and a new study finds that future warming could decimate the western U.S. over the next century.
Pollution from fossil fuels decreased rainfall in Central America
(02/10/2015) Fossil fuel pollution may have caused a southern shift in a vital rainfall belt across Central America, according to a new study in Nature Geoscience, potentially leading to drier conditions and droughts in some northern tropical countries. Using data from a single stalagmite in a Belizean cave, the researchers were able to create an accurate record of both rainfall and temperature for the last 450 years.
How termites hold back the desert
(02/05/2015) Some termite species erect massive mounds that look like great temples springing up from the world's savannas and drylands. But aside from their aesthetic appeal—and incredible engineering—new research in Science finds that these structures do something remarkable for the ecosystem: they hold back the desert.
Changing California forests may help us prepare for the future
(01/21/2015) A new study published by the Proceedings of the National Academy of Sciences examines how California’s forests have changed since the 1930s--and, according to its authors, can help us understand how forests will respond to the changing global climate in the future.
Top 10 Environmental Stories of 2014
(12/23/2014) In 2014, the unimaginable happened: companies representing the majority of palm oil production and trade agreed to stop cutting down rainforests and draining peatlands for new oil palm plantations. After years of intense campaigning by environmentalists and dire warnings from scientists, nearly two dozen major producers, traders, and buyers established zero deforestation policies.
Amazon rainforest is getting drier, confirms another study
(10/30/2014) Parts of the Amazon rainforest are getting considerably less rain, leading trees to absorb less carbon, finds a study published this week in the journal Proceedings of the National Academy of Sciences.
Could California be facing a mega-drought?
(10/13/2014) Scientists and politicians, everyone agrees: California is in deep trouble. As the state enters its fourth year of drought and the soil has never been drier. Some look at the sky with hope that El Niño will bring much needed rain. But most are starting to wonder if this is just the beginning. Are we entering a mega-drought that could last for more than a decade?
Indonesia's forests so damaged they burn whether or not there's drought
(08/21/2014) Air pollution caused by fires set for land-clearing on Sumatra has become a regularly occurrence in Southeast Asia. While these fires are often termed forest fires, the reality is much of the area that burns each year has already been deforested and today mostly consists of grass, scrub, and remnants of what was once forest. But the impacts are nonetheless very substantial, finds a new study published in the journal Scientific Reports.
Climate-linked drought cutting forests' carbon-storing ability
(07/08/2014) Climate extremes are dramatically cutting the ability of trees to sequester carbon, threatening to convert some forests from carbon sinks into carbon sources, finds a study published this month in Environmental Research Letters.
Congo rainforest losing its greenness, finds NASA
(04/25/2014) The Congo, the world's second largest rainforest, is losing its greenness, finds a new study published in Nature.
Rainforests on fire: climate change is pushing the Amazon over the edge
(04/18/2014) From 1999-2010, nearly three percent of the Amazon rainforest burned, and climate forecasts indicate dry conditions conducive to fire will only become more commonplace in the future. A new study indicates that rainforests are more vulnerable to fire than previously thought, and it warns the current combination of climate change and deforestation may be pushing Amazon forests past the breaking point.
Featured video: Showtime releases first episode of major new climate change series online
(04/08/2014) Although Showtime's landmark new climate change series doesn't premiere until Sunday, the network has released an edited version of the first episode of Years of Living Dangerously to the public (see below). The nine-part documentary series is being billed as a "groundbreaking" exploration into the many ways that climate change is already wreaking havoc on the lives of people around the world.
How locals and conservationists saved the elephants of Mali amidst conflict and poverty
(04/02/2014) At a time when Africa's elephants are facing a relentless poaching crisis, one community has managed to safeguard their elephants in the most unlikely of places: Mali. In a country that has suffered from widespread poverty, environmental degradation, and, most recently, warfare, a collaboration between conservationists and the local community has kept Mali's elephants from extinction.
Is Brazil's epic drought a taste of the future?
(02/25/2014) With more than 140 cities implementing water rationing, analysts warning of collapsing soy and coffee exports, and reservoirs and rivers running precipitously low, talk about the World Cup in some parts of Brazil has been sidelined by concerns about an epic drought affecting the country's agricultural heartland.
Drought, fire reducing ability of Amazon rainforest to store carbon
(02/06/2014) New research published in Nature adds further evidence to the argument that drought and fire are reducing the Amazon's ability to store carbon, raising concerns that Earth's largest rainforest could tip from a carbon sink to a carbon source.
Amazon rainforest does not 'green up' during the dry season
(02/06/2014) Analysis of satellite imagery has cleared up a controversy over whether the Amazon rainforest 'greens up' during the dry season.
NASA picture reveals shocking impact of California's drought
(01/25/2014) A pair of satellite images released this week by NASA reveal the shocking impact of California's drought, which is now entering its third year.
Amazon deforestation could cause droughts in California
(11/08/2013) Complete deforestation of the Amazon rainforest could reduce rainfall in the Pacific Northwest by up to 20 percent and snowpack in the Sierra Nevada by up to 50 percent, suggests new research published in the Journal of Climate. The study is based on high resolution computer modeling that stripped the Amazon of its forest cover and assessed the potential impact on wind and precipitation patterns. While the scenario is implausible, it reveals the global nature of the ecological services afforded by the world's largest rainforest.
Deforestation may hurt U.S. agriculture, affect monsoon cycle
(11/04/2013) Unchecked deforestation will have far-reaching impacts on temperature, rainfall, and monsoon cycles in regions well outside the tropics, affecting agriculture and water availability, warns a new report published by Greenpeace International. The report is a synthesis of dozens of recent scientific papers that assess the effects of forest cover loss on weather patterns, local climate, and agricultural productivity.
Climate change to hurt children most
(09/25/2013) Children will bear the brunt of the impact of climate change because of their increased risk of health problems, malnutrition and migration, according to a new study published on Monday. And food prices are likely to soar as a result of warming, undoing the progress made in combating world hunger.
Worst drought in 30 years threatens millions in southern Africa with food insecurity
(08/19/2013) Around 2 million people face food insecurity in northern Namibia and southern Angola as the worst regional drought in decades takes its toll, according to the UN. Two years of failed rains have pushed families into desperate conditions in a region already known for its desert-like conditions. In Namibia alone, experts estimate that over 100,000 children under five are at risk for acute malnutrition.
Zoo races to save extreme butterfly from extinction
(08/15/2013) In a large room that used to house aquatic mammals at the Minnesota Zoo, Erik Runquist holds up a vial and says, 'Here are its eggs.' I peer inside and see small specks, pale with a dot of brown at the top; they look like a single grain of cous cous or quinoa. Runquist explains that the brown on the top is the head cap of the larva, a fact that becomes more clear under a microscope when you can see the encased larva squirm. I'm looking at the eggs of a Poweshiek skipperling, a species that is more imperiled than pandas, tigers, or bluewhales. Once superabundant, only several hundred Poweshiek skipperlings may survive on Earth today and the eggs I'm looking at are the only ones in captivity.
Fracking sucks up all the water from Texas town
(08/15/2013) Beverly McGuire saw the warning signs before the town well went dry: sand in the toilet bowl, the sputter of air in the tap, a pump working overtime to no effect. But it still did not prepare her for the night last month when she turned on the tap and discovered the tiny town where she had made her home for 35 years was out of water.
Amazon fire risk on the rise, says NASA
(06/09/2013) The Amazon rainforest is facing a higher risk of fires this dry season, warns a fire prediction system developed by researchers using NASA and NOAA data.
NASA: 3% of Amazon rainforest burned between 1999-2010
(06/08/2013) 33,000 square miles (85,500 square kilometers) or 2.8 percent of the Amazon rainforest burned between 1999-2010 finds new NASA-led research that measured the extent of fires that smolder under the forest canopy.
Water crisis widening: 4.5 billion people live near 'impaired water sources'
(05/28/2013) The majority of the 9 billion people on Earth will live with severe pressure on fresh water within the space of two generations as climate change, pollution and over-use of resources take their toll, 500 scientists have warned.
Featured video: How climate change is messing with the jetstream
(05/08/2013) Weather patterns around the globe are getting weirder and weirder: heat waves and record snow storms in Spring, blasts of Arctic air followed by sudden summer, record deluges and then drought.
'Suffering...without witnesses': over a quarter of a million people perished in Somali famine
(05/06/2013) A new report estimates that 258,000 people died in 2011 during a famine in Somalia, the worst of such events in 25 years and a number at least double the highest estimations during the crisis. Over half of the victims, around 133,000, were children five and under. The report, by the UN Food and Agricultural Organization (FAO), argues that the international community reacted too late and too little to stem the mass starvation brought on by government instability, conflict, high food prices, and failed rains, the last of which has been linked to climate change by some scientists.
Indigenous tribes say effects of climate change already felt in Amazon rainforest
(04/30/2013) Tribal groups in Earth's largest rainforest are already being affected by shifts wrought by climate change, reports a paper published last week in the British journal Philosophical Transactions of the Royal Society B. The paper, which is based on a collection of interviews conducted with indigenous leaders in the Brazilian Amazon, says that native populations are reporting shifts in precipitation patterns, humidity, river levels, temperature, and fire and agricultural cycles. These shifts, measured against celestial timing used by indigenous groups, are affecting traditional ways of life that date back thousands of years.
Burned rainforest vulnerable to grass invasion
(04/24/2013) Rainforests that have been affected by even low-intensity fires are far more vulnerable to invasion by grasses, finds a new study published in special issue of the journal Philosophical Transactions of the Royal Society B. The findings are significant because they suggest that burned forests may be more susceptible to subsequent fires which may burn more intensely due to increased fuel loads.
Featured video: stemming human-caused fires in the Amazon
(04/09/2013) A new series of 5 films highlights how people use fire in the Amazon rainforest and how such practices can be mitigated. Collectively dubbed "Slash & Burn" each film explores a different aspect of fire-use in the Amazon. In recent years the Amazon has faced unprecedented droughts, possibly linked to climate change and vast deforestation, making the issue of human-started fires even more important.
Australia reels from record heatwave, fires
(01/09/2013) Yesterday Australia recorded its highest average temperature yet: 40.33 degrees Celsius (104.59 Fahrenheit). The nation has been sweltering under an unprecedented summer heatwave that has spawned wildfires across the nation, including on the island of Tasmania where over 100 houses were engulfed over the weekend. Temperatures are finally falling slightly today, providing a short reprieve before they are expected to rise again this weekend.
2012 was America's warmest year on record
(01/08/2013) 2012 was the warmest year on record for the contiguous U.S. according to the National Oceanic and Atmospheric Administration (NOAA).
Amazon rainforest failing to recover after droughts
(12/24/2012) The impact of a major drought in the Amazon rainforest in 2005 persisted far longer than previously believed, raising questions about the world's largest tropical forest to cope with the expected impacts of climate change, reports a new study published in the journal Proceedings of the National Academy of Sciences.
Top 10 Environmental Stories of 2012
(12/18/2012) Below is a quick review of some of the biggest environmental stories of 2012. The 'top stories' are listed in no particular order. Climate change, overpopulation, consumption, and ecological destruction is pushing planet Earth toward a tipping point according to a major study in Nature released over the summer. This could result in a new 'planetary state' that would be far harsher and bleaker than the current one (beginning around 12,000 years ago), which saw the rise and success of human society.
Advanced technology reveals massive tree die-off in remote, unexplored parts of the Amazon
(12/12/2012) Severe drought conditions in 2010 appear to have substantially increased tree mortality in the Western Amazon, a region thought largely immune from the worst effects of changes occurring in other parts of the world's largest rainforest, reported research presented last week at the fall meeting of the American Geophysical Union (AGU). The findings suggest that the Amazon may face higher-the-expected vulnerability to climate change, potentially undercutting its ability to help mitigate greenhouse gas emissions by absorbing carbon dioxide through faster growth.
Forests worldwide near tipping-point from drought
(11/23/2012) Forests worldwide are at 'equally high risk' to die-off from drought conditions, warns a new study published this week in the journal Nature. The study, conducted by an international team of scientists, assessed the specific physiological effects of drought on 226 tree species at 81 sites in different biomes around the world. It found that 70 percent of the species sampled are particularly vulnerable to reduction in water availability. With drought conditions increasing around the globe due to climate change and deforestation, the research suggests large swathes of the world's forests — and the services they afford — may be approaching a tipping point.
World Bank: 4 degrees Celsius warming would be miserable
(11/20/2012) A new report by the World Bank paints a bleak picture of life on Earth in 80 years: global temperatures have risen by 4 degrees Celsius spurring rapidly rising sea levels and devastating droughts. Global agriculture is under constant threat; economies have been hampered; coastal cities are repeatedly flooded; coral reefs are dissolving from ocean acidification; and species worldwide are vanishing. This, according to the World Bank, is where we are headed even if all of the world's nations meet their pledges on cutting greenhouse gas emissions. However, the report also notes that with swift, aggressive action it's still possible to ensure that global temperatures don't rise above 4 degrees Celsius.
Remembering the Dust Bowl: it could happen again
(11/15/2012) The Dust Bowl, a film by Ken Burns and Dayton Duncan, and The Dust Bowl: An Illustrated History, a book authored by Dayton Duncan and Ken Burns, chronicles the worst man-made ecological disaster in American history. Told in first-person narrative by survivors of the Dust Bowl and brought to color through vivid storytelling and over 300 rare archival photos, these two combined efforts must be watched and read by those concerned with our human impact on Earth.
Obama breaks climate silence at press conference
(11/14/2012) At a news conference today, a question by New York Times reporter Mark Landler pushed President Obama to speak at some length about climate change. In his answer, Obama re-iterated his acceptance of climate science and discussed how progress on tackling climate change might proceed in his second term, though he also noted that he wouldn't put action on the climate ahead of the economy. President Obama made a small reference to climate change in his victory speech following his historic re-election last Tuesday, but his answer today was the most the president has talked about the issue at any length since at least Hurricane Sandy.
One in eight people suffer from malnutrition worldwide
(10/16/2012) In a world where technology has advanced to a point where I can instantly have a face-to-face conversation via online video with a friend in Tokyo, nearly 870 million people, or one in eight, still suffer from malnutrition, according to a new UN report. While worldwide hunger declined from 1990 to 2007, progress was slowed by the global economic crisis. Over the last few years, numerous and record-breaking extreme weather events have also taken tolls on food production. Currently, food prices hover just below crisis levels.
Over 70 percent of Americans: climate change worsening extreme weather
(10/10/2012) According to a new poll, 74 percent of Americans agree that climate change is impacting weather in the U.S., including 73 percent who agreed, strongly or somewhat, that climate change had exacerbated record high temperatures over the summer. The findings mean that a large majority of Americans agree with climatologists who in recent years have found increasingly strong evidence that climate change has both increased and worsened extreme weather events.
Climate change causing forest die-off globally
(09/09/2012) Already facing an onslaught of threats from logging and conversion for agriculture, forests worldwide are increasingly impacted by the effects of climate change, including drought, heightened fire risk, and disease, putting the ecological services they afford in jeopardy, warns a new paper published in the journal Nature Climate Change.
Drought drives corn prices to record high
(08/09/2012) Drought in America's Midwest drive corn prices to record highs on Thursday.
Extreme heatwaves 50 to 100 times more likely due to climate change
(08/05/2012) A recent rise in deadly, debilitating, and expensive heatwaves was caused by climate change, argues a new statistical analysis published in the Proceedings of the National Academy of Sciences (PNAS). Climatologists found that extreme heatwaves have increased by at least 50 times during the last 30 years. The researchers, including James Hansen of NASA, conclude that climate change is the only explanation for such a statistical jump.
Drought pits farmers against frackers
(08/01/2012) Drought has created a standoff over water supplies in the U.S. Midwest between energy producers and farmers, reports Bloomberg. Natural gas and oil producers have been forced to seek new water sources as they mull calls from farmers and activists to recycle their water, a practice that would make 'fracking' more expensive.
Featured video: climate change bringing on the extremes
(07/24/2012) Focusing on extreme weather events in the U.S. this summer, a new compilation video highlights the connection between climate change and increasing and worsening extremes, such as heatwaves, droughts, and floods.
U.S. drought could set in motion global food crisis
(07/23/2012) The U.S. is suffering drought levels not seen in over 50 years—and drawing comparisons to the Dust Bowl—with 56 percent of the contiguous U.S. in moderate to extreme drought. Some experts fear that the drought, and resulting hikes in food prices, could propel another global food crisis like those seen in 2008 and 2010.
Drought, heat, fires push more Americans to accept reality of climate change
(07/19/2012) Record temperatures, wildfires, drought, and crop failures have is helping convince more Americans that climate change is real and occurring, reports Bloomberg.
Borneo's forests face dire future from global warming
(07/18/2012) Already wracked by extensive deforestation and forest degradation, the future looks grim for Borneo's tropical rainforests, reports a new study published in the Journal of Geophysical Research-Biogeosciences.
Deja vu: U.S. undergoes hottest 12 months on record...again and again
(07/12/2012) According to new data from the National Oceanic and Atmospheric Administration (NOAA)'s National Climatic Data Center, the last twelve months have been the warmest on record for the contiguous United States. This record, set between July 2011 through June 2012, beat the last consecutive twelve month record set only a month earlier between June 2011 and May 2012, which in turn beat the previous record holder, you guessed it: May 2011 through April 2012.
Climate change increased the probability of Texas drought, African famine, and other extreme weather
(07/11/2012) Climate change is here and its increasing the chances for crazy weather, according to scientists. A prestigious group of climatologists have released a landmark report that makes the dramatic point that climate change is impacting our weather systems—and in turn our food crops, our economies, and even our lives—here-and-now. The new report in the American Meteorological Society is first of what is intended to be an annual offering that will attempt to tease out the connections between climate change and individual extreme weather events, such as heatwaves, droughts and floods.
Scientist: 'no doubt' that climate change is playing a role in U.S. fires
(07/02/2012) A noted climate scientist says there is 'no doubt' that climate change is 'playing a role' in this year's series of record fires in the western U.S. A massive wildfire in Colorado has forced the evacuation of 36,000 people, destroyed over 300 homes, and killed two people. The devastation wrought by the Waldo Canyon Fire even prompted a visit form U.S. President Barack Obama. But this is not the only epic fire in the U.S. this year: less than a month before the Colorado disaster, New Mexico experienced its largest fire on record in Gila Nation Forest; the conflagration burned up 247,000 acres (100,000 hectares). Other major wildfires have occurred in Utah and Wyoming, as well as other parts of New Mexico and Colorado.
NASA image: New Mexico suffers record megafire
(06/04/2012) To date, around 250,000 acres (101,000 hectares) of the Gila Forest in New Mexico have burned in the state's largest fire ever recorded. Begun on May 16th due to lightning strikes, the unprecedented fire has likely been made possible by a combination of land-use changes, unflagging drought, and climate change.
The vanishing Niger River imperils tourism and livelihoods in the desert
(06/04/2012) Severely affected by recent turmoil across its northern frontiers, Nigerien tourism pins hope on river valley attractions to play a major role in rebuilding its tourism industry in the upcoming years. Even though the river itself is threatened. Located in the heart of the Sahel Region, the vast desert lands of Niger have captivated European tourists seeking a taste of its immensely varied natural landscapes.
Featured video: climate, water, and desperation in Texas
(05/01/2012) As a part of PBS' new series Coping with Climate Change reporters visited several towns in Texas, which has suffered unprecedented drought beginning in 2010. The drought, which climatologists say is consistent with climate change predictions, has led to forest fires, vast tree mortalities, agricultural and livestock losses, and water shortages.
Scientists unlock indigenous secret to sustainable agriculture in the Amazon's savannas
(04/11/2012) Indigenous populations in the Amazon successfully farmed without the use of fire before the arrival of Europeans, demonstrating a potentially sustainable approach to land management in a region that is increasingly vulnerable to man-made fires.
"Strong evidence" linking extreme heatwaves, floods, and droughts to climate change
(03/28/2012) As North America recovers from what noted meteorologist Jeff Masters has called "the most incredible spring heatwave in U.S. and Canadian recorded history," a new paper argues that climate change is playing an important role in a world that appears increasingly pummeled by extreme weather. Published in Nature Climate Change, the paper surveys recent studies of climate change and extreme weather and finds "strong evidence" of a link between a warming world and the frequency and intensity of droughts, floods, and heatwaves—such as the one that turned winter into summer in the U.S.
Bad feedback loop: climate change diminishing Canadian forest's carbon sink
(01/30/2012) Climate change, in the form of rising temperatures and less precipitation, is shrinking the carbon sink of western Canada's forest, according to a new study released today in the Proceedings of the National Academy of Sciences (PNAS). Tree mortality and a general loss of biomass has cut the carbon storage capacity of Canada's boreal forests by around 7.28 million tons of carbon annually, equal to nearly 4 percent of Canada's total yearly carbon emissions.
Deforestation, climate change threaten the ecological resilience of the Amazon rainforest
(01/19/2012) The combination of deforestation, forest degradation, and the effects of climate change are weakening the resilience of the Amazon rainforest ecosystem, potentially leading to loss of carbon storage and changes in rainfall patterns and river discharge, finds a comprehensive review published in the journal Nature.
Delayed response to Somalia famine cost thousands of lives
(01/18/2012) A hesitant response by the international community likely led to thousands of unnecessary deaths in last year's famine in East Africa finds a new report released by Oxfam and Save the Children. The report, entitled A Dangerous Delay, says that early warning systems worked in informing the international community about the likelihood of a dire food crisis in East Africa, however a "culture of risk aversion" led to months-long delays. By the time aid arrived it was already too late for many. The British government has estimated somewhere between 50,000 and 100,000 people perished in the famine, half of whom were likely children under five.
Top 10 Environmental Stories of 2011
(12/22/2011) Many of 2011's most dramatic stories on environmental issues came from people taking to the streets. With governments and corporations slow to tackle massive environmental problems, people have begun to assert themselves. Victories were seen on four continents: in Bolivia a draconian response to protestors embarrassed the government, causing them to drop plans to build a road through Tipnis, an indigenous Amazonian reserve; in Myanmar, a nation not known for bowing to public demands, large protests pushed the government to cancel a massive Chinese hydroelectric project; in Borneo a three-year struggle to stop the construction of a coal plant on the coast of the Coral Triangle ended in victory for activists; in Britain plans to privatize forests created such a public outcry that the government not only pulled back but also apologized; and in the U.S. civil disobedience and massive marches pressured the Obama Administration to delay a decision on the controversial Keystone XL pipeline, which would bring tar sands from Canada to a global market.
Earth systems disruption: Does 2011 indicate the "new normal" of climate chaos and conflict?
(12/21/2011) The year 2011 has presented the world with a shocking increase in irregular weather and disasters linked to climate change. Just as the 2007 "big melt" of summer arctic sea ice sent scientists and environmentalists scrambling to re-evaluate the severity of climate change, so have recent events forced major revisions and updates in climate science.
Texas loses half a billion trees to epic drought
(12/21/2011) A punishing drought in Texas has not only damaged crops, killed cattle, and led to widespread fires, but has also killed off a significant portion of the state's trees: between 100 and 500 million trees have perished to drought stress according to preliminary analysis. The estimate does not include tree mortality caused by fires. The drought has been linked to La Niña conditions, which causes drying in the Southern U.S., and has likely been exacerbated by global climate change.
Droughts could push parts of Africa back into famine
(12/19/2011) Drought and erratic rains could lead to further food scarcities in Africa warns the United Nations World Food Program (WFP). The WFP singles out South Sudan, the world's newest nation, and Niger as nations of particular concern. Earlier this year famine killed scores of people, including an estimated 30,000 children, in Somalia.
Is the Russian Forest Code a warning for Brazil?
(12/19/2011) Brazil, which last week moved to reform its Forest Code, may find lessons in Russia's revision of its forest law in 2007, say a pair of Russian scientists. The Brazilian Senate last week passed a bill that would relax some of forest provisions imposed on landowners. Environmentalists blasted the move, arguing that the new Forest Code — provided it is not vetoed by Brazilian President Dilma Rousseff next year — could undermine the country's progress in reducing deforestation.
Evidence mounts that Maya did themselves in through deforestation
(12/08/2011) Researchers have garnered further evidence for a smoking gun behind the fall of the great Maya civilization: deforestation. At the American Geophysical Union (AGU) conference, climatologist Ben Cook presented recent research showing how the destruction of rainforests by the Mayan ultimately led to declines in precipitation and possibly civilization-rocking droughts. While the idea that the Maya may have committed ecological-suicide through deforestation has been widely discussed, including in Jared Diamond's popular book Collapse, Cook's findings add greater weight to the theory.
Monarch butterflies decline at wintering grounds in Mexico, Texas drought adds to stress to migration
(11/10/2011) Every fall, millions of monarch butterflies travel south to Mexico and take refuge in twelve mountain sanctuaries of oyamel fir forests. Now, declining numbers of the overwintering butterflies expose the migration’s vulnerability and raise questions about threats throughout the monarch’s lifecycle. A study published online last spring in Insect Conservation and Diversity shows a decrease in Mexico’s overwintering monarch butterflies between 1994 and 2011. The butterflies face loss of wintering habitat in Mexico and breeding habitat in the United States. Extreme weather, like winter storms in Mexico and the ongoing drought in Texas, adds yet another challenge.
Climate change already worsening weird, deadly, and expensive weather
(11/02/2011) Unprecedented flooding in Thailand, torrential rains pummeling El Salvador, long-term and beyond-extreme drought in Texas, killer snowstorm in the eastern US—and that's just the last month or so. Extreme weather worldwide appears to be both increasing in frequency and intensity, and a new report from the Intergovernmental Panel on Climate Change (IPCC) connects the dots between wilder weather patterns and global climate change.
Killer Russian heatwave product of climate change
(10/26/2011) Last year's Russian heatwave and drought resulted in vast wildfires and a morality rate that was 56,000 people higher than the same period in 2009. Now, researchers have published a paper in the Proceedings of the National Academy of Sciences (PNAS) that finds the heatwave would very likely have never happened if not for climate change. The study flies in the face of previous research by the National Oceanic and Atmospheric Administration (NOAA) that concluded the heatwave was simply due to natural variation and not a warming world.
2010 Amazon drought released more carbon than India's annual emissions
(10/09/2011) The 2010 drought that affected much of the Amazon rainforest triggered the release of nearly 500 million tons of carbon (1.8 billion tons of carbon dioxide) into the atmosphere, or more than the total emissions from deforestation in the region over the period, estimates a new study published in the journal Environmental Research Letters.
World's newest nation faces prospect of famine
(10/06/2011) As East Africa reels from a devastating famine, which is hitting Somalia the hardest, there are new fears that another African nation could soon slip into a similar situation. On July 9th of this year, South Sudan became the world's newest nation; however a few months later drought, conflict, refugees, and rising food prices could push the eastern region of South Sudan into a famine, warned officials from the fledgling nation yesterday.
Photos: World Food Program works to save lives in East Africa famine
(08/28/2011) Over 12 million people across East Africa are imperiled by a hunger crisis brought on by extreme drought. The worst of the crisis is in Somalia, where famine has been declared in 5 areas of Somalia to date—the first famine to be declared by the UN in three decades. Somalia is unique, because here the drought has been exacerbated by a long-failed government and militants. Refugee camps have been set up in Kenya and Ethiopia, but are strained. A number of aid groups are working on the ground to provide emergency food and medical attention to hunger victims, but funding is still below what is needed. The largest group is probably the UN's World Food Program (WFP). Mongabay.com spoke to Dena Gubaitis, Communications Officer for the WFP, for background on the famine and how relief efforts are going on the ground.
Climate change may fuel increase in warfare, finds study
(08/24/2011) Civil war is twice as likely in tropical countries during particularly hot and dry years, according to a new study in Nature. The researchers found that El Niño conditions, which generally cuts rainfall and raises temperatures in the tropics, may have played a factor in one-fifth of the world's total conflicts during the past 50 years. El Niño conditions occur every 3-7 years. While the study did not examine global climate change in conjunction with conflict, the study links a warmer world to a more conflict-prone one, as least in the tropics.
Lessons from the world's longest study of rainforest fragments
(08/15/2011) For over 30 years, hundreds of scientists have scoured eleven forest fragments in the Amazon seeking answers to big questions: how do forest fragments' species and microclimate differ from their intact relatives? Will rainforest fragments provide a safe haven for imperiled species or are they last stand for the living dead? Should conservation focus on saving forest fragments or is it more important to focus the fight on big tropical landscapes? Are forest fragments capable of regrowth and expansion? Can a forest—once cut-off—heal itself? Such questions are increasingly important as forest fragments—patches of forest that are separated from larger forest landscapes due to expanding agriculture, pasture, or fire—increase worldwide along with the human footprint.
Famine spreads: 29,000 young children perish
(08/04/2011) As the UN announces that famine has spread in Somalia to three additional regions (making five in total now), the US has put the first number to the amount of children under 5 who have so far perished from starvation in the last 90 days: 29,000. Nearly half of the total population of Somalia is currently in need of emergency food assistance. Yet, the al Qaeda-linked group al-Shabaab, which controls parts of Somalia, has made bringing assistance to many of the malnourished incredibly difficult, if not impossible. The famine in Somalia has been brought-on by lack of governance combined with crippling droughts throughout East Africa, which some experts have linked to climate change. High food prices worldwide and a lagging response by the international community and donors have made matters only worse.
Chart: US suffers record drought
(08/01/2011) An exceptional drought is still scorching major parts of Texas, New Mexico, Oklahoma, and Louisiana. A new report from the National Drought Mitigation Center finds that over July, nearly 12 percent of the US saw exceptional drought conditions, the highest record since monitoring began a dozen years. Exceptional drought is the worst possible on a 5-scale drought scale.
Adaptation, justice and morality in a warming world
(07/28/2011) If last year was the first in which climate change impacts became apparent worldwide—unprecedented drought and fires in Russia, megaflood in Pakistan, record drought in the Amazon, deadly floods in South America, plus record highs all over the place—this may be the year in which the American public sees climate change as no longer distant and abstract, but happening at home. With burning across the southwest, record drought in Texas, majors flooding in the Midwest, heatwaves everywhere, its becoming harder and harder to ignore the obvious. Climate change consultant and blogger, Brian Thomas, says these patterns are pushing 'prominent scientists' to state 'more explicitly that the pattern we're seeing today shows a definite climate change link,' but that it may not yet change the public perception in the US.
U.S. park to reopen after massive peat forest fires
(07/24/2011) Authorities are reopening Okefenokee National Wildlife Refuge in Georgia five weeks after the 402,000-acre swamp was closed due to a massive forest fire sparked by a lightning strike during the state's severe drought.
Tens of thousands starving to death in East Africa
(07/20/2011) As the US media is focused like a laser on theatric debt talks and the UK media is agog at the heinous Rupert Murdoch scandal, millions of people are undergoing a starvation crisis in East Africa. The UN has upgraded the disaster—driven by high food prices, conflict, and prolonged drought linked by some to climate change—to famine in parts of Somalia today. Mark Bowden, UN humanitarian coordinator for Somalia, has said that tens of thousands Somalis have died from malnutrition recently, "the majority of whom were children."
Amazon drought and forest fire prediction system devised
(07/18/2011) Researchers have devised a model to anticipate drought and forest fires in the Amazon rainforest.
Global forests offset 16% of fossil fuel emissions
(07/14/2011) Between 1990 and 2007 global forests absorbed nearly one-sixth of all carbon released by fossil fuel emissions, reports a new study published in Science. The results suggest forests play an even bigger role in fighting climate change than previously believed.
Worst drought in 60 years brings starvation fears to East Africa
(06/30/2011) A prolonged drought in East Africa is bringing many of the region's impoverished to their knees: the World Food Program (WFP) is warning that 10 million people in the region are facing severe shortages. While not dubbed a famine yet, experts say it could become one. Meanwhile, a recent study by FEWS NET/USGS has revealed that the current drought is the worst in 11 of 15 East African regions since 1950-51. Worsening droughts are one of the predictions for the region as the world grows warmer.
Climate change and deforestation pose risk to Amazon rainforest
(05/20/2011) Deforestation and climate change will likely decimate much of the Amazon rainforest, says a new study by Brazil’s National Institute for Space Research (INPE) and the UK's Met Office Hadley Centre. Climate change and widespread deforestation is expected to cause warmer and drier conditions overall, reducing the resistance of the rainforest ecosystem to natural and human-caused stressors while increasing the frequency of extreme rainfall events and droughts by the end of this century. While climate models show that higher temperatures resulting from global climate change will threaten the resilience of the Amazon, current deforestation is an immediate concern to the rainforest ecosystem and is likely driving regional changes in climate.
Burning up: warmer world means the rise of megafires
(05/12/2011) Megafires are likely both worsened by and contributing to global climate change, according to a new United Nations report. In the tropics, deforestation is playing a major role in creating giant, unprecedented fires.
Are US floods, fires linked to climate change?
(04/28/2011) The short answer to the question of whether or not on-going floods in the US Midwest and fires in Texas are linked to a warming Earth is: maybe. The long answer, however, is that while it is difficult—some argue impossible—for scientists to link a single extreme weather event to climate change, climate models have long shown that extreme weather events will both intensify and become more frequent as the world continues to heat up. In other words, the probability of such extreme events increases along with global average temperature.
NASA image reveals extent of 2010 Amazon drought
(04/17/2011) NASA has revealed a satellite image of the crippling effect of last year's record-breaking drought on the Amazon ecosystem. For those of you counting, that's two record droughts in the Amazon Basin in 5 years.
Last year's drought hit Amazon hard: nearly a million square miles impacted
(03/29/2011) A new study on its way to being published shows that the Amazon rainforest suffered greatly from last year's drought. Employing satellite data and supercomputing technology, researchers have found that the Amazon was likely hit harder by last year's drought than a recent severe drought from 2005. The droughts have supported predictions by the Intergovernmental Panel on Climate Change's (IPCC) that climate change, among other impacts, could push portions of the Amazon to grasslands, devastating the world's greatest rainforest. "The greenness levels of Amazonian vegetation—a measure of its health—decreased dramatically over an area more than three and one-half times the size of Texas and did not recover to normal levels, even after the drought ended in late October 2010," explains the study's lead author Liang Xu of Boston University.
What's behind the 85% decline of mammals in West Africa's parks?
(03/28/2011) A recent, well-covered study found that African mammals populations are in steep decline in the continent's protected areas. Large mammal populations over forty years have dropped by 59% on average in Africa [read an interview on the study here] and by 85% in west and central Africa, according to the study headed by Ian Craigie, which links the decline to continuing habitat degradation as well as hunting and human-wildlife conflict. However, a new opinion piece in mongabay.com's open access journal Tropical Conservation Science argues that this study missed an important factor in central and west Africa where the decline in mammals was the worst: rainfall.
Food crisis 2011?: drought in China could push food prices even higher
(02/09/2011) The UN's Food and Agriculture Organization (FAO) has warned that a drought in China could devastate the nation's winter wheat crop and further inflate food prices worldwide. Already, food prices hit a record high in January according to the FAO. Rising 3.4 percent since December, prices reached the highest point since tracking began in 1990. While many fear a food crisis similar to the one in 2008-2007, experts say the world has more food in reserve this time around and gasoline, at least for now, remains cheaper. However, if China loses its winter wheat that could scuttle any hopes of avoiding another price rise in crop staples.
Two massive droughts evidence that climate change is 'playing Russian roulette' with Amazon
(02/03/2011) In 2005 the Amazon rainforest underwent a massive drought that was labeled a one-in-100 year event. The subsequent die-off of trees from the drought released 5 billion tons of CO2. Just five years later another major drought struck. The 2010 drought, which desiccated entire rivers, may have been even worse according to a new study in Science, adding on-the-ground evidence to fears that climate change may inevitably transform the world's greatest rainforest.
Top 10 Environmental Stories of 2010
(12/20/2010) Below is a quick review of some of the biggest environmental stories of 2010: Climate change rears it ugly head; Oil spill in the Gulf; Agreement to save global biodiversity; Illegal logging crisis in Madagascar; REDD kicks off in Indonesia; Brazil deforestation falls to its lowest level; Hungary's red sludge; Nestle caves to social media activists; New mammals galore' and Global climate framework back on the table?
'These are the facts': 2010 to be among top three hottest years
(12/02/2010) Despite La Nina arriving at the end of the year—which bring cooler than average conditions—and bitter cold showing up recently in the Northern Hemisphere due to the North Atlantic Oscillation (NAO), 2010 was smoldering enough worldwide that it will very likely be among the top three hottest years since record-keeping began 160 years ago, reports the World Meteorological Organization (WMO) today.
Climate change linked to 21,000 deaths in nine months
(11/30/2010) Extreme weather events linked to climate change has caused the deaths of 21,000 people worldwide in the first nine months of 2010, according to Oxfam. This is already twice the casualties of 2009. In a new report More than ever: climate talks that work for those that need them most, the organization outlines the casualties of such weather-related disasters, for example devastating floods in Pakistan which killed 2,000 people and affected more than 20 million.
Earth could see 4 degrees Celsius warming in less than a lifetime
(11/29/2010) By the time children born this year reach 50 years old, the Earth could be 4 degrees Celsius warmer (7.2 degrees Fahrenheit) warns a new study as governments meet in Cancun for this year's UN climate summit, which is not expected to produce an agreement. Last year governments pledged in the non-binding Copenhagen Accord to keep temperatures below a 2 degree Celsius rise, but a new study in Philosophical Transactions of the Royal Society A argues that even with current promises to cut emissions this is unlikely and, in a worst-case scenario, a rise of 4 degrees Celsius is possible by 2060.
Amazon suffers worst drought in decades
(10/24/2010) The worst drought since 1963 has created a regional disaster in the Brazilian Amazon. Severely low water levels have isolated communities dependent on river transport. Given a worsening situation, Brazil announced on Friday an emergency package of $13.5 million for water purification, tents, and food airdrops.
NASA image captures one of the warmest Julys on record
(08/19/2010) The NASA Goddard Institute for Space Studies (GISS) has found that the global average temperature of July 2010 was nearly 1 degree Fahrenheit (0.55 degrees Celsius) higher than average temperatures from July1951-1980. In fact, this July was tied for the warmest on record with July 2005 and 1998.
Exploring Kenya's sky island
(08/18/2010) Rising over 2,500 meters from Kenya's northern desert, the Mathews Range is a sky island: isolated mountain forests surrounded by valleys. Long cut off from other forests, 'sky islands' such as this often contain unique species and ecosystems. Supported by the Nature Conservancy, an expedition including local community programs Northern Rangelands Trust and Namunyak Conservancy recently spent a week surveying the mountain range, expanding the range of a number of species and discovering what is likely a new insect.
New NASA images reveal devastating impact of Russian fires
(08/11/2010) A new series of images released by NASA show the extent of smoke hovering over Moscow and Central European Russia, while another image measures the amount of carbon monoxide in the area, a gas which can produce a number of health problems. Russia is in the midst of a full-scale disaster as hundreds of forest and peatland fires are covering part of the world's largest nation in a thick cloud of smoke. Temperatures in Moscow and elsewhere have broken past heat records several times in the last month while a long drought combined with fires have led to the loss of 20 percent of Russia's grain crop, causing Prime Minister Vladimir Putin to ban grain exports. Russian officials say that it;s likely some 15,000 people to date have died from the disaster.
Summer from hell: seventeen nations hit all-time heat records
(08/09/2010) The summer isn't over yet, but already seventeen nations have matched or beaten their all-time heat records. According to Jeff Masters' WunderBlog, Belarus, the Ukraine, Cyprus, Russia, Finland, Qatar, the Sudan, Saudi Arabia, Niger, Chad, Kuwait, Iraq, Pakistan, Colombia, Myanmar, Ascension Island, and the Solomon Islands have all equaled or broken their top temperature records this year. In addition, the hottest temperature ever recorded in Asia was taken in Pakistan at 128 degrees Fahrenheit (53 degrees Celsius); this incredible temperature still has to be reviewed by the World Meteorological Organization (WMO).
