(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.
