'Suffering...without witnesses': over a quarter of a million people perished in Somali famine

2013-05-06T13:58:00Z

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

2013-04-30T21:46:00Z

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

2013-04-24T17:10:00Z

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

2013-04-09T14:50:00Z

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

2013-01-09T17:52:00Z

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.

Amazon rainforest failing to recover after droughts

2012-12-24T20:36:00Z

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.

Advanced technology reveals massive tree die-off in remote, unexplored parts of the Amazon

2012-12-12T19:52:00Z

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

2012-11-23T22:00:00Z

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

2012-11-20T00:23:00Z

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

2012-11-15T09:07:00Z

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

2012-11-14T21:02:00Z

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

2012-10-16T17:37:00Z

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

2012-10-10T15:31:00Z

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

2012-09-09T23:39:00Z

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.

Extreme heatwaves 50 to 100 times more likely due to climate change

2012-08-05T17:53:00Z

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

2012-08-01T00:24:00Z

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

2012-07-24T16:06:00Z

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

2012-07-23T20:40:00Z

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.

Deja vu: U.S. undergoes hottest 12 months on record...again and again

2012-07-12T20:55:00Z

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

2012-07-11T18:58:00Z

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

2012-07-02T14:09:00Z

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

2012-06-04T16:34:00Z

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.

2012-06-04T14:19:00Z

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

2012-05-01T17:19:00Z

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

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

2012-03-28T11:07:00Z

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

2012-01-30T19:59:00Z

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

2012-01-19T02:02:00Z

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

2012-01-18T20:51:00Z

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.

Earth systems disruption: Does 2011 indicate the "new normal" of climate chaos and conflict?

2011-12-21T19:02:00Z

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

2011-12-21T17:35:00Z

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

2011-12-19T15:39:00Z

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?

2011-12-19T14:48:00Z

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

2011-12-08T17:32:00Z

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

2011-11-10T21:30:00Z

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

2011-11-02T16:41:00Z

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

2011-10-26T16:04:00Z

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

2011-10-09T14:34:00Z

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

2011-10-06T18:32:00Z

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

2011-08-28T16:30:00Z

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.
