NASA image shows decline in maximum sea ice extent
(03/28/2012) Data released by the National Snow and Ice Data Center (NSIDC) shows that Arctic sea ice for the winter of 2011-2012 reached its maximum extent on March 18 at 15.24 million square kilometers (5.88 million square miles). The mark is well below the 1979–2000 average, but was above the record low of the 2010–2011 winter.
Cloud forests may be particularly vulnerable to climate change
(03/26/2012) Mexico could lose nearly 70 percent of its cloud forests due to climate change by 2080, according to new research published in Nature Climate Change, that has implications for cloud forests worldwide.
NASA image: records shattered across U.S. as summer arrives before spring
(03/22/2012) Central U.S. and parts of Canada have seen over a thousand record temperatures shattered over the past week and a half, as an abnormally-long and bizarrely-hot warm spell moves across portions of North America. The direct cause of the weird weather is a blocked high pressure system, but as the U.S. experiences what may be the warmest March on record, meteorologists say climate change may be playing a role in the severity of the heatwave.
Featured Video: FEVER, the climate change challenge for indigenous people
(03/21/2012) Four short films have been produced highlighting the challenges of climate change for indigenous people in the tropics. Produced by LifeMosaic, the indigenous right organization says the films are "designed to inform and empower indigenous communities."
2010, not 1998, warmest year on record
(03/20/2012) An updated temperature analysis by the Met Office and the University of East Anglia's Climatic Research Unit has confirmed that 2010, not 1998, was the warmest year since record keeping began in the late 19th Century. The new analysis adds in temperature data from 400 stations across northern Canada, Russia, and the Arctic, which had been left out of the previous analysis.
Featured Video: the true cost of the tar sands
(03/15/2012) What's the big deal about the tar sands? Canadian photographer Garth Lenz presents the local environmental and social concerns presented by the tar sands in a concise, impassioned speech in a TEDx talk in Victoria, Canada.
Climate change could increase fires, logging, and hunting in rainforests
(03/13/2012) The combined impacts of deforestation and climate change will bring a host of new troubles for the world's tropical rainforests argues a new study in Trends in Ecology and Evolution. Drying rainforests due to climate change could lead to previously inaccessible forests falling to loggers, burning in unprecedented fires, or being overexploited by hunters.
Climate journalism gone awry
(03/12/2012) A leading journalist and editor at The Atlantic made a startling admission regarding how she writes about climate science last week. Megan McArdle, who not long ago wrote in-depth about documents leaked from Heartland Institute, has noted that as a journalist she depends on her comprehension of climate science on two non-experts and one climatologist who is widely viewed as an outlier for his view that climate change may actually be good for the world.
Environmental news - month in review: wildlife traffickers busted, funders of climate denial revealed
(03/08/2012) Mongabay.com provides a quick review of forest-related news for February 2012.
Tornado season likely to expand due to climate change
(03/06/2012) Last Friday, around a hundred tornadoes left a wake of destruction in the U.S., killing 39 people to date and destroying entire towns. The tragedy hit hardest in Kentucky and Indiana and experts predict the weather-disaster will cost over $1 billion. But isn't this early for tornado season? Yes, say experts, and climatologists add that while research on tornadoes and climate change is currently in its infancy, it's possible, probably even likely, that climate change is expanding tornado season in the U.S. due to the earlier arrival of spring.
TransCanada to build southern half of Keystone to avoid State Department approval
(02/29/2012) Keystone XL is becoming the project that refuses to die: TransCanada, the company behind the pipeline, has said it plans to build the southern half of the pipeline while it waits to determine a new route for the northern section. The company does not need approval from the State Department, which turned down the entire pipeline in January, to build the southern half from Texas to Oklahoma. However, the Obama Administration has embraced the idea. Carrying carbon-intensive tar sands oil down from Canada to a global market, the proposed pipeline galvanized environmental and climate activists last year, resulting in several large protests and civil disobedience actions.
Birders beware: climate change could push 600 tropical birds into extinction
(02/21/2012) There may be less birds for birders to see in the world as the planet warms. Climate change, in combination with deforestation, could send between 100 and 2,500 tropical birds to extinction before the end of century, according to new research published in Biological Conservation. The wide range depends on the extent of climate and how much habitat is lost, but researchers say the most likely range of extinctions is between 600 and 900 species, meaning about 10-14 percent of tropical birds, excluding migratory species.
Six nations, including U.S., set up climate initiative to target short-term greenhouse gases
(02/20/2012) With global negotiations to tackle carbon emissions progressing interminably, nations are seeking roundabout ways to combat global climate change. U.S. Secretary of State, Hillary Clinton, announced in India last week a new six nation initiative to target non-carbon greenhouse gases, including soot (also known as "black carbon"), methane, and hydro-fluorocarbons (HFCs). Reductions of these emissions would not only impact short-term climate change, but also improve health and agriculture worldwide according to a recent study in Science.
Arctic warms to highest level yet as researchers fear tipping points
(02/13/2012) Last year the Arctic, which is warming faster than anywhere else on Earth due to global climate change, experienced its warmest twelve months yet. According to recent data by NASA, average Arctic temperatures in 2011 were 2.28 degrees Celsius (4.1 degrees Fahrenheit) above those recorded from 1951-1980. As the Arctic warms, imperiling its biodiversity and indigenous people, researchers are increasingly concerned that the region will hit climatic tipping points that could severely impact the rest of the world. A recent commentary in Nature Climate Change highlighted a number of tipping points that keep scientists awake at night.
Humans drove rainforest into savannah in ancient Africa
(02/09/2012) Three thousand years ago (around 1000 BCE) several large sections of the Congo rainforest in central Africa suddenly vanished and became savannah. Scientists have long believed the loss of the forest was due to changes in the climate, however a new study in Science implicates an additional culprit: humans. The study argues that a migration of farmers into the region led to rapid land-use changes from agriculture and iron smelting, eventually causing the collapse of rainforest in places and a rise of grasslands. The study has implications for today as scientists warn that the potent combination of deforestation and climate change could flip parts of the Amazon rainforest as well into savannah.
Black Swans and bottom-up environmental action
(02/08/2012) The defining events shaping the modern world - economic, social, environmental, progressive and disruptive - are frequently characterized as "Black Swans."The Black Swan term and theory were characterized by author and analyst Nassim Nicholas Taleb who explains, "What we call here a Black Swan (and capitalize it) is an event with the following three attributes. First, it is an outlier, as it lies outside the realm of regular expectations, because nothing in the past can convincingly point to its possibility. Second, it carries an extreme impact. Third, in spite of its outlier status, human nature makes us concoct explanations for its occurrence after the fact, making it explainable and predictable." Taleb identifies the emergence of the internet, the attacks of September 11, 2001, the popularity of Facebook, stock market crashes, the success of Harry Potter, and World War I as among Black Swan events.
Kelly Blynn: activists not "letting the pressure off" on Keystone pipeline
(02/06/2012) Along with Bill McKibben and a small cadre of passionate environmental activists, Kelly Blynn co-founded the climate activism group "350." 350 exemplifies the power of online networks combined with activism and has coordinated some of the largest and most successful environmental protests in history. The 350 team has organized more than 5,200 events in 181 countries around the world. Kelly graduated from Middlebury College with a degree in Geography and Environmental Studies and experience coordinating one of the largest university campus environmental activism groups in the United States. Blynn is currently situated in Washington, D.C.
Wall Street Journal climate op-ed: the "equivalent of dentists practicing cardiology"
(02/06/2012) Climate scientists have struck back at the Wall Street Journal after it published an op-ed authored by 16 mostly non-climatologists arguing that global warming was not an urgent concern. The response letter, entitled Check With Climate Scientists for Views on Climate, responds that the Wall Street Journal should seek input on global warming from climate scientists. Six of the 16 authors who published the original article have ties to Exxon Mobil and their professions range from engineers to astronauts. In turn the letter to Wall Street Journal was signed by 38 well-noted climatologists.
Jellyfish explosion may be natural cycle
(02/06/2012) Evidence that jellyfish are taking over the oceans is currently lacking, according to a new study published in Bioscience. Complied by a number of marine experts, the study found that while jellyfish have been on the rise in some regions it is likely due to a natural cycle of jellyfish populations and not a global boom. Researchers, including a number of marine biologists, have warned for years that jellyfish numbers may be exploding due to human activities, such as overfishing, warmer oceans due to global climate change, and the rise of oxygen-depleted, so-called "dead zones."
Environmental news - month in review: setbacks for the palm oil industry, climate outlook darkens
(02/02/2012) Here mongabay.com provides a quick review of forest-related news for January 2012.
Majority of Andes' biodiversity hotspots remain unprotected
(02/01/2012) Around 80 percent of the Andes' most biodiverse and important ecosystems are unprotected according to a new paper published in the open-access journal BMC Ecology. Looking at a broad range of ecosystems across the Andes in Peru and Bolivia, the study found that 226 endemic species, those found no-where else, were afforded no protection whatsoever. Yet time is running out, as Andean ecosystems are undergoing incredible strain: a combination of climate change and habitat destruction may be pushing many species into ever-shrinking pockets of habitat until they literally have no-where to go.
New meteorological theory argues that the world's forests are rainmakers
(02/01/2012) New, radical theories in science often take time to be accepted, especially those that directly challenge longstanding ideas, contemporary policy or cultural norms. The fact that the Earth revolves around the sun, and not vice-versa, took centuries to gain widespread scientific and public acceptance. While Darwin's theory of evolution was quickly grasped by biologists, portions of the public today, especially in places like the U.S., still disbelieve. Currently, the near total consensus by climatologists that human activities are warming the Earth continues to be challenged by outsiders. Whether or not the biotic pump theory will one day fall into this grouping remains to be seen. First published in 2007 by two Russian physicists, Victor Gorshkov and Anastassia Makarieva, the still little-known biotic pump theory postulates that forests are the driving force behind precipitation over land masses.
Wall Street Journal under attack for climate op-ed
(01/31/2012) The Wall Street Journal is under attack for publishing an op-ed attacking climate science last Friday, while turning down another op-ed explaining climate change and signed by 255 researchers with the U.S. National Academy of Sciences, which was eventually published in the journal Science. The op-ed last Friday first garnered attention because it was signed by 16 scientists, however other journalists have shown that most of these signatories are not climatologists (the list includes an astronaut, a physician, and an airplane engineer), many are well-known deniers, and at least six have been tied to the fossil fuels industry.
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.
California sets tough new clean car standards
(01/30/2012) The U.S. state that takes climate change most seriously—California—has unanimously approved new rules dubbed the Advanced Clean Cars program to lower carbon emissions, reduce oil dependence, mitigate health impacts from pollution, and save consumers money in the long-term. According to the new standards, by 2025 cars sold in California must cut greenhouse gas emissions by 34 percent and smog emissions by 75 percent. The program will also require 15.4 percent of all cars sold in California to be zero or near-zero emissions by 2025.
Featured video: NASA releases shocking 30 second film on climate
(01/30/2012) NASA has created a new animation showing global temperatures on a map of the Earth from 1880-2011. On the map, blues represent temperatures lower than baseline averages, while reds indicate temperatures higher than the average. As the 131 years pass, the map turns from bluish-white to increasingly yellow and red. Caused by the burning of fossil fuels, deforestation, agricultural practices, and other human impacts, climate change has currently raised temperatures 0.8 degrees Celsius (1.44 degrees Fahrenheit) higher than the Industrial Revolution average.
U.S. media favored Keystone pipeline in coverage
(01/26/2012) A new report by Media Matters finds that U.S. TV and print media were largely biased toward the construction of TransCanada's Keystone XL Pipeline, which the Obama administration recently turned down. The report finds that guests and quotes were largely in favor of the pipeline in addition to news outlets consistently repeating job figures for the pipeline that have been discredited.
Sustainable Materials With Both Eyes Open: A book review
(01/26/2012) Sustainable Materials With Both Eyes Open: Future Buildings, vehicles, products and equipment – made efficiently and made with less new material is a remarkable popular impartial well-written engineering book that addresses sustainable production of cement, plastic, paper, aluminum and steel and their long-term impacts on the environment. The authors provide a comprehensive background regarding the uses of said materials.
Climate and The Oceans - Princeton Primers in Climate: A Book Review
(01/25/2012) Climate and The Oceans by Dr. Geoffrey K. Vallis provides a coherent, well-articulated primer on how the oceans impact the Earth's climate. This easy-to-read illustrated book, filled with both data and accessible mathematical equations demonstrating the impact of the oceans on the Earth's climate, offers practitioners and stakeholders' state-of-the-art scientific analysis of how the oceans and climate interact that is both user friendly to the non-expert yet scientifically rigorous enough as bridge material for graduate students as they grapple with the compelling field of climate science and oceanography.
Acid oceans: in some regions acidification a 'hundred times greater' than natural variation
(01/24/2012) Emissions of carbon over the last two centuries have raised the acidity of the oceans to the highest levels in 21,000 years and likely beyond, according to a new study in Nature Climate Change. The change threatens a number of marine species, including coral reefs and molluscs.
The Cryosphere-Princeton primers in climate: A Book Review
(01/23/2012) The Cryosphere by Dr. Shawn J. Marshall, Canada Research Chair in Climate Change, University of Calgary, is an excellent book because it summarizes leading scientific research into easily accessible chapters each one on a different component of the cryosphere. The cryosphere, which incorporates the Earth's snow and ice mass including seasonal snow, permafrost (both land-based permafrost and below water permafrost), river and lake ice, sea ice, glaciers, ice sheets, and ice shelves, is intrinsically related to global climate change. Hence, understanding how the cryosphere interacts with and is at risk because of climate change and its greenhouse gases is fundamental to developing effective policy mechanisms that mitigate climate change.
NASA: 2011 ninth warmest year yet
(01/23/2012) Despite being a strong La Niña year, which tends to be cooler than the average year, 2011 was the ninth warmest year on record and the warmest La Niña yet, according to a global temperature analysis by NASA. To date, nine of the world's ten warmest years have occurred since 2000 according to data going back to 1880.
Hugh Powell: birds lend invaluable insight into ecosystems
(01/23/2012) Hugh Powell is science editor at the Cornell Lab of Ornithology as well as a contributor to Woods Hole Oceanographic Institution's Oceanus and other publications. He's traveled extensively while writing, including stints in Antarctica for WHOI's Live from the Poles. Before finding his niche as a science writer, Hugh studied the interconnections between black-backed woodpeckers, insects, and forest fires in Montana. He currently resides in Ithaca, New York.
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.
Obama rejects Keystone pipeline, but leaves door open for tar sands
(01/18/2012) The Obama administration today announced it is scrapping TransCanada's Keystone pipeline after Republicans forced a 60-day deadline on the issue in a Congressional rider. The State Department advised against the pipeline arguing that the deadline did not give the department enough time to determine if the pipeline "served the national interest." The cancellation of the pipeline is a victory for environmental and social activists who fought the project for months, but Republicans are blasting the administration.
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.
One company behind U.S.'s top three biggest greenhouse gas emitters
(01/16/2012) The Atlanta-based Southern company owns the top three biggest sources of greenhouse gas emissions in the U.S. according to recent data released by the Environmental Protection Agency (EPA). Three of Southern's coal-fired plants—two in Georgia and one in Alabama—account for around 64.74 million metric tons of total greenhouse gas emissions, higher than all of Finland's carbon emission in 2008.
Climate change may make lizards smarter, if they don't go extinct first
(01/12/2012) A new study in Biology Letters has found that warmer temperatures may make lizards smarter, even as past studies have linked a global decline in lizards to climate change.
Targeting methane, black carbon could buy world a little time on climate change
(01/12/2012) A new study in Science argues that reducing methane and black carbon emissions would bring global health, agriculture, and climate benefits. While such reductions would not replace the need to reduce CO2 emissions, they could have the result of lowering global temperature by 0.5 degrees Celsius (0.9 degree Fahrenheit) by mid-century, as well as having the added benefits of saving lives and boosting agricultural yields. In addition, the authors contend that dealing with black carbon and methane now would be inexpensive and politically feasible.
Seals, birds, and alpine plants suffer under climate change
(01/11/2012) The number of species identified by scientists as vulnerable to climate change continues to rise along with the Earth's temperature. Recent studies have found that a warmer world is leading to premature deaths of harp seal pups (Pagophilus groenlandicus) in the Arctic, a decline of some duck species in Canada, shrinking alpine meadows in Europe, and indirect pressure on mountain songbirds and plants in the U.S. Scientists have long known that climate change will upend ecosystems worldwide, creating climate winners and losers, and likely leading to waves of extinction. While the impacts of climate change on polar bears and coral reefs have been well-documented, every year scientists add new species to the list of those already threatened by anthropogenic climate change.
How lemurs fight climate change
(01/09/2012) Kara Moses may have never become a biologist if not for a coin toss. The coin, which came up heads and decided Moses' direction in college, has led her on a sinuous path from studying lemurs in captivity to environmental writing, and back to lemurs, only this time tracking them in their natural habitat. Her recent research on ruffed lemurs is attracting attention for documenting the seed dispersal capabilities of Critically Endangered ruffed lemurs as well as theorizing connections between Madagascar's lemurs and the carbon storage capacity of its forests. Focusing on the black-and-white ruffed lemur's (Varecia variegata) ecological role as a seed disperser—animals that play a major role in spreading a plant's seeds far-and-wide—Moses suggests that not only do the lemurs disperse key tree species, but they could be instrumental in dispersing big species that store large amounts of carbon.
Climate change media coverage drops 20 percent in 2011
(01/05/2012) Global media reporting on climate change issues was down again last year, according to a new analysis from The Daily Climate. The news organization counted around 19,000 stories on climate issues during the year written by 7,140 journalists, falling 20 percent from 2010 levels.
Ecuador makes $116 million to not drill for oil in Amazon
(01/02/2012) A possibly ground-breaking idea has been kept on life support after Ecuador revealed its Yasuni-ITT Initiative had raked in $116 million before the end of the year, breaking the $100 million mark that Ecuador said it needed to keep the program alive. Ecuador is proposing to not drill for an estimated 850 million barrels of oil in the Ishpingo-Tambococha-Tiputinin (ITT) blocs of Yasuni National Park if the international community pledges $3.6 billion to a United Nations Development Fund (UNDF), or about half of what the oil is currently worth. The Yasuni-ITT Initiative would preserve arguably the most biodiverse region on Earth from oil exploitation, safeguard indigenous populations, and keep an estimated 410 million tons of CO2 out of the atmosphere. However, the initiative is not without its detractors, some arguing the program is little more than blackmail; meanwhile proponents say it could prove an effective way to combat climate change, deforestation, and mass extinction.
The year in review for rainforests
(12/28/2011) 2011 was designated as "Year of the Forests" by the United Nations. While there was relatively little progress on intergovernmental forest protection programs during the year, a lot happened elsewhere. Below is a look at some of the biggest tropical forest-related news stories for 2011. We at mongabay readily acknowledge there were a number of important temperate and boreal forest developments, including Britain's decision not to privatize its forests and the severe drought in Texas, but this article will cover only tropical forest news.
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.
Philippines disaster may have been worsened by climate change, deforestation
(12/20/2011) As the Philippines begins to bury more than a 1,000 disaster victims in mass graves, Philippine President Benigno Aquino has ordered an investigation into last weekend's flash flood and landslide, including looking at the role of illegal logging. Officials have pointed to both climate change and vast deforestation as likely exacerbating the disaster.
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.
Facebook pledges to go green...someday soon
(12/15/2011) After a massive campaign by Greenpeace to get everyone's favorite social media site to quit coal energy, Facebook has announced a new energy policy and a partnership with Greenpeace. The policy includes a goal "to power all of our operations with clean and renewable energy," however does not go so far as to state it is dropping coal at this time or give a timeline as to when it may do so. Still, Greenpeace is calling the new policy by Facebook a victory.
