Photos: Madagascar's wonderful and wild frogs, an interview with Sahonagasy
(03/03/2010) To save Madagascar's embattled and beautiful amphibians, scientists are turning to the web. A new site built by herpetologists, Sahonagasy, is dedicated to gathering and providing information about Madagascar's unique amphibians in a bid to save them from the growing threat of extinction. "The past 20 years have seen resources wasted because of a poor coordination of efforts," explains Miguel Vences, herpetologist and professor at the Technical University of Braunschweig. "Many surveys and reports have been produced that were never published, many tourists found and photographed amphibians but these photos were not made available to mapping projects, many studies carried out by Malagasy students did not make use of literature because it was not available."
Polar bears are newcomers on the world stage
(03/01/2010) One of the most well-known animals, the polar bear, is a newcomer on the world stage, according to research published in the Proceedings of the National Academy of Sciences. By studying the DNA of an ancient polar bear jawbone uncovered in 2004 in Norway scientists have for the first time pinpointed the time when the polar bear split from its closest relative, the brown bear. "Our results confirm that the polar bear is an evolutionarily young species that split off from brown bears some 150,000 years ago and evolved extremely rapidly during the late Pleistocene, perhaps adapting to the opening of new habitats and food sources in response to climate changes just before the last interglacial period."
Galapagos fur seals exploit warmer waters to establish colony off Peru
(02/25/2010) As suggested by their name, the Galapagos fur seals were once endemic to the Galapagos island chain off the coast of Ecuador. But in a warming world species are on the move, and the Galapagos fur seal is no exception. According to a recent story in Reuters the Galapagos fur seals have established what appears to be a permanent colony off the coast of Peru, 900 miles from their home.
Grizzly bears move into polar bear territory, threatening polar cubs
(02/24/2010) Two of the world's largest land carnivores are converging on the same territory, according to data recently published in Canadian Field Naturalist. Grizzly bears ( Ursus arctos horribilis) are moving into an area that has long been considered prime polar bear habitat in Manitoba, Canada. Although polar bears (Ursus maritimus) are bigger than their grizzly relatives—they are the world's largest land carnivores—biologists are concerned that grizzlies will kill polar cubs, further threatening the polar bear, which is already thought to be imperiled by ice loss in the Arctic.
Climate change melting southern Antarctic Peninsula ice shelves
(02/23/2010) The US Geological Survey (USGS) has found that every ice front in the southern part of the Antarctic Peninsula—the coldest part—has been retreating overall for the past sixty years with the greatest changes visible since 1990.
Local vegetation can point to the consequences of climate change, Israeli scientists say after extensive studies
(02/23/2010) A recent study by a team of researchers from Bar Ilan University suggests that endangered plants in water-saturated habitats can be taken as indicators for climate change in the Levant region. They present a picture particularly of the consequences of changes in precipitation.
"No change whatsoever" in scientists' conviction that climate change is occurring
(02/22/2010) Despite some politicians and TV personalities claiming that climate change is dead, a panel of influential US and European scientists held a press conference at the annual meeting of the American Association for the Advancement of Science to set the record straight on the state of the science and the recent media frenzy against climate change. "There has been no change in the scientific community, no change whatsoever" in the consensus that globally temperatures are rising, said Gerald North, professor of atmospheric sciences at Texas A&M University. Recent data has shown that the decade from 2000-2009 was the warmest decade on record.
Decline in fog threatens California's iconic redwood ecosystems
(02/15/2010) A surprising new study finds that during the past century the frequency of fog along California's coast has declined by approximately three hours a day. Published in the Proceedings of the National Academy of Sciences the researchers are concerned that this decrease in fog threatens California's giant redwoods and the unique ecosystem they inhabit.
Desertification threatens 38 percent of the world
(02/10/2010) Over one third of the world's land surface (38 percent) is threatened with desertification, according to a new study published in theInternational Journal of Life Cycle Assessment. The study found that eight of fifteen eco-regions are threatened by desertification, including coastal areas, the prairies, the Mediterranean region, the savannah, the temperate steppes, the temperate deserts, tropical and subtropical steppes, and the tropical and subtropical deserts.
New spiny pocket mouse discovered in the mountainous rainforests of Venezuela
(02/08/2010) Researchers have discovered a new species of spiny mouse that lives on four mountainous forests in the Cordillera de la Costa mountain range of Venezuela.
The Amazongate fiasco
(02/03/2010) A claim published in the Sunday Times over the veracity of a statement published in an Intergovernmental Panel on Climate Change (IPCC) report may land the British newspaper in hot water. On Sunday, Jonathan Leake, Science & Environment Editor of the Sunday Times, accused the IPCC of making a "bogus rainforest claim" when it cited a report warning that up to 40 percent of the Amazon could be "drastically" affected by climate change. Climate change skeptics immediately seized on "Amazongate" as further evidence to discredit the IPCC just two weeks after it was found to be using shoddy glacier data in its 2007 climate assessment.
Rainforest expert agrees with IPCC: warns of 'tipping point' for Amazon
(02/03/2010) Amid questions over the Amazon forests' capacity to survive climate change, a renowned tropical biologist says that in fact the fears are real, reports Tierramerica. Speaking at the Biodiversity Science Policy Conference in Paris, Thomas Lovejoy, biodiversity chair at the Washington DC-based Heinz Center for Science, Economics and the Environment, and chief biodiversity adviser to the president of the World Bank, described the Amazon rainforest as "very close to a tipping point".
NASA: Arctic melt season lengthening
(02/03/2010) Newly released images from NASA and the National Snow and Ice Data Center show that the Arctic's melt season has lengthened significantly over the past few decades.
On World Wetland's Day bad news for America's iconic ducks
(02/02/2010) World Wetland Day 2010 brings with it new research on America's prairie wetlands and bad news for the country's waterfowl. A new study in BioScience finds that America's prairies are greatly susceptible to climate change: a warmer and drier prairie will desiccate wetlands needed by ducks and other waterfowl for food, shelter, and breeding.
Jumbo squid explosion
(02/02/2010) Jumbo squid are back in the waters of Southern California and anglers are seeing an uptick in business, reports the Los Angeles Times.
Photos: New tropical frog undergoes remarkable transformation
(02/01/2010) Nature never runs out of surprises. Exploring Sudest Island off of Papua New Guinea, researchers discovered a new species of frog that drastically changes its appearance from juvenile to adulthood, a transformation that has never been seen in another frog.The new species, named Oreophryne ezra, is shiny black with bright yellow spots. Yet when it matures, the frog becomes rose-colored and even its eyes change from black to blue.
Photos: expedition in Ecuador reveals numerous new species in threatened cloud forest
(01/14/2010) An expedition into rainforests on Ecuador's coast by Reptile & Amphibian Ecology International (RAEI) have revealed a number of possible new species including a blunt-snouted, slug-eating snake; four stick insects; and up to 30 new 'rain' frogs. The blunt-snouted snake, which feeds on gastropods like slugs, is especially interesting, as its closest relative is in Peru, 350 miles away. In addition, a fifteen-year-old volunteer with the organization found a snake that specializes on snails. The researchers are unsure of this is a new species: the closest similar snake is 600 miles away in Panama.
Climate change pushes massive Antarctic glacier past tipping point
(01/14/2010) A new study shows that a major Antarctic glacier has likely passed its tipping point, putting it on track to lose 50 percent of its ice in 100 years. Such a loss is estimated to raise global sea levels by 24 centimeters (9.4 inches), according to the study published in the Proceedings of Royal Society A.
If protected coral reefs can recover from global warming damage
(01/10/2010) A study in the Caribbean has found that coral reefs can recover from global warming impacts, such as coral bleaching, if protected from fishing. Marine biologists have long been worried that coral reefs affected by climate change may be beyond recovery, however the new study published in PLoS ONE shows that alleviating another threat, overfishing, may allow coral reefs to cope with climate change.
Bottom-dwelling sea animals play surprising role in carbon sequestration
(01/07/2010) Researchers have long known that some marine animals, such as plankton, play big roles in the carbon cycle, but a new study shows that a long-ignored family of marine animals, the bottom-dwelling echinoderms, also do their part in the carbon cycle.
Chinese official links extreme snowstorm to global warming
(01/05/2010) Bitter cold and snow have shut down Beijing after it received 4-8 inches (10-20 centimeters) of snow on Sunday, the largest snowfall since 1951, according to the Sydney Morning Herald. Guo Hu, the head of the Beijing Meteorological Bureau linked the storm to global climate change.
A 'dangerous world' for migratory birds, an interview with Sarah Lehnen
(01/04/2010) Sarah Lehnen has worked with America's rich birdlife for a decade: she has studied everything from songbirds inhabiting dwindling shrub land in Ohio to shorebirds stopping over in the Mississippi Rive alluvial valley, always with an eye towards conservation. Most recently she has been involved in testing migratory birds for avian flu. It may come as a surprise, but American birds are in serious decline. In March of last year, US Secretary of the Interior, Ken Salazar, announced that one-in-three American birds are endangered. Even once common birds are showing precipitous declines. Birds face a barrage of threats, which are only complicated—and heightened—for migratory birds.
Gone: a look at extinction over the past decade
(01/03/2010) No one can say with any certainty how many species went extinct from 2000-2009. Because no one knows if the world's species number 3 million or 30 million, it is impossible to guess how many known species—let alone unknown—may have vanished recently. Species in tropical forests and the world's oceans are notoriously under-surveyed leaving gaping holes where species can vanish taking all of their secrets—even knowledge of their existence—with them.
Record-breaking snow across the US and climate change
(12/26/2009) Over the past few weeks the United States has been pounded by a number of big snow storms. A week ago Washington DC received 18 inches of snow, setting a number of records. Over Christmas, the middle of the country, from Texas to Minnesota was also hit by record amounts of snow. While snow fall over the East Coast and middle of the country in the United States in December is hardly unusual, a number of record amounts of precipitation may point to a larger shift in the climate. Scientists say that higher temperatures causes more water evaporation, which increases the chances of heavy precipitation events, such as floods and snowstorms.
Catastrophic sea level rise could occur with only two degrees Celsius warming
(12/17/2009) Allowing the climate to rise by just two degrees Celsius—the target most industrialized nations are currently discussing in Copenhagen—may still lead to a catastrophic sea level rise of six to nine meters, according to a new study in Nature. While this rise in sea levels would take hundreds of years to fully occur, inaction this century could lock the world into this fate.
Is the US sinking climate change talks at Copenhagen?
(12/16/2009) While it's difficult to know what's truly going on inside the Bella Center at the UN Climate Change Conference in Copenhagen, a pattern seems to be emerging of the United States being unwilling to compromise on, well, anything.
Pope Benedict: environmental crisis requires review of world's economic model
(12/15/2009) Pope Benedict XVI has released a message linking world peace with preserving the environment for the World Day of Peace, which will be held on January 1st 2010. In it Benedict calls for a "long-term review" of the world's current economic model, including "[moving] beyond a purely consumerist mentality" and encouraging a more "sober lifestyle".
Well-known climate change denialist labels activists in Copenhagen 'Hitler Youth'
(12/15/2009) Prominent climate change denialist and past advisor to Margaret Thatcher, Viscount Christopher Monckton, has persisted in labeling protestors in Copenhagen 'Hitler Youth' despite little historical connection.
Climate change causing irreversible acidification in world's oceans
(12/15/2009) A new study from the Secretariat of the Convention on Biological Diversity has synthesized over 300 reports on ocean acidification caused by climate change. The report finds that increasing acidification will lead to irreversible damage in the world's oceans, creating a less biodiverse marine environment. Released today the report determines that the threat to marine life by ocean acidification must be considered by policymakers at the UN Climate Change Conference in Copenhagen.
Photos: ten beloved species threatened by global warming
(12/14/2009) The International Union for the Conservation of Nature (IUCN) has released a list of ten species that are likely to be among the hardest hit by climate change, including beloved species such as the leatherback sea turtle, the koala, the emperor penguin, the clownfish, and the beluga whale. The timing of the list coincides with the negotiations by world leaders at the UN Climate Change Conference to come up with an international agreement to combat climate change.
Sea levels set to rise more than expected due to 'deeply surprising' Greenland melt
(12/14/2009) A new study by the Arctic Monitoring and Assessment Program estimates that the sea will rise by 0.5 to 1.5 meters by 2100, threatening coastal cities and flooding island nations. This is double the predicted rise estimated by the UN's Intergovernmental Panel on climate Change (IPCC) in 2007, which did not incorporate sea level rise due to the melting of Greenland and Antarctica's ice sheets.
Obama on global warming and forest protection
(12/10/2009) President of the United States, Barack Obama, was in Oslo, Norway this morning accepting the Nobel Peace Prize, which he won in part for promising to bring the United States to the negotiating table on climate change—something he has recently done.
US think-tank: islands affected by global warming should wait for trickle-down money
(12/09/2009) Poor island nations threatened by rising seas should wait for money through trickle-down economics, according to the founder of the US Competitive Enterprise Institute. The Washington-based free-market think tank believes that curbing greenhouse gas emissions to combat climate change will be too costly to the US and global economies.
Islands and African nations present toughest treaty yet to combat global warming
(12/09/2009) Led by the small island state of Tuvalu, developing nations particularly vulnerable to climate change have put forward the most ambitious plan yet to mitigate climate change. Their move has split them from usual partners, such as China, India, Saudi Arabia, and South Africa, who are concerned about the economic consequences of the proposal.
Bangladesh tops list of most vulnerable countries to climate change
(12/09/2009) According to the Global Climate Risk Index, Bangladesh is the most vulnerable nation to extreme weather events, which many scientists say are being exacerbated by climate change. From 1990 to 2008, Bangladesh has lost 8,241 lives on average every year due to natural disasters. In addition, rising sea levels also threaten millions of Bangladeshis.
Current decade is the warmest on record
(12/08/2009) As 192 countries meet in Copenhagen to wrangle out a complex and at times sticky agreement to combat climate change, the World Meteorological Organization (WMO) has released new evidence that the world is undergoing warming. According to the WMO the current decade is likely the warmest on record.
Canada, not Copenhagen, hit by protests over climate policy
(12/08/2009) While tens of thousands of protestors have gone to Copenhagen to call on world governments to do more to fight against climate change, the most surprising protest on the first day of the Climate Change Conference in Copenhagen occurred thousands of miles away: in Canada.
Profile of the carbon footprint of the global poor: the challenge of alleviating poverty and fighting global warming
(12/07/2009) Two of the world's most serious issues—poverty and climate change—are interconnected. With a rise in one's income there usually comes a rise in one's carbon footprint, thereby threatening the environment. Wealthy nations have the highest per capita carbon footprints, while developing nations like India and China—which are experiencing unprecedented economic growth—are becoming massive contributors of greenhouse gases. However, it is those who have the smallest carbon footprint—the world's poor—who currently suffer most from climate change. Food crises, water shortages, extreme weather, and rising sea levels have all hit the poor the hardest.
Email scandal may be turning against climate change deniers
(12/07/2009) It may be that climate change scientists and policymakers have simply had enough, and it may be that the emails which were hacked did not reveal the massive conspiracy that they were supposed to, either way climatologists and politicians have gone on the offensive against claims that the hacked emails from the East Anglia's Climate Research Unit are evidence that climate change is a conspiracy or hoax.
Extinctions on the rise in the Galapagos: fishing and global warming devastating islands' species
(12/03/2009) We may never see again the Galapagos black-spotted damselfish, the beautiful 24-rayed sunstar, or the Galapagos stringweed. These species from Galapagos waters may all very well be extinct. Other species are on the brink, such as the Galapagos penguin and the Floreana cup coral. A new report in Global Change Biology reveals that in just a matter of decades, overfishing and climate change has devastated the Galapagos' unique and famous ecosystems.
James Hansen says Copenhagen approach "fundamentally wrong" would be better to "reassess"
(12/03/2009) James Hansen, one of the world's foremost climatologists, told the Guardian today that he believes the Copenhagen talks are flawed to the point where failure of the talks may be the best way forward. "The approach that is being talked about is so fundamentally wrong that it would be better to reassess," Hansen said.
Not just the polar bear: ten American species that are feeling the heat from global warming
(12/01/2009) A new report, America’s Hottest Species, highlights a variety of American wildlife that are currently threatened by climate change from a small bird to a coral reef to the world’s largest marine turtle.
World leaders falling over themselves to show up at Copenhagen
(12/01/2009) If you’re a world leader and you won’t be in Copenhagen next week you might feel out of the loop. Currently 98 heads of state have agreed to attend the Climate Change Summit in Copenhagen—nearly half of the 192 member nations of the UN.
World requires radical new economic models to fight poverty and mitigate global warming
(11/30/2009) A new report calls for a radical re-envisioning of current economic models in order to tackle poverty, mitigate and adapt to climate change, and solve other environmental problems. The report was crafted by the New Economics Foundation (NEF) and the International Institute for Environment and Development (IIED) and was supported by The Working Group on Climate Change and Development, which includes a wide variety of well-known groups, including environmental, religious, and anti-poverty organizations.
What would the Dalai Lama do?: spiritual leader speaks out on climate change
(11/30/2009) The Dalai Lama has given up taking baths in favor of showers and makes certain all lights are off when he leaves a room to help lower his carbon footprint, he told a crowd of reporters in Sydney Australia today.
Global warming will increase likelihood of civil war in Africa by 55 percent
(11/23/2009) There have been many warnings by policymakers that rising temperatures in Africa could lead to civil conflict, however a new study in Proceedings of the National Academy of Sciences is the first to uncover empirical evidence for these warnings and quantify them. The results—that higher temperatures increased the likelihood of civil war in sub-Saharan Africa by over 50 percent—took aback even the researchers.
Oceans' ability to sequester carbon diminishing
(11/18/2009) A new study—the first of its kind—has completed an annual accounting of the oceans' intake of carbon over the past 250 years, and the news is troubling. According to the study, published in Nature, the oceans' ability to sequester carbon is struggling to keep-up with mankind's ever-growing emissions. Since 2000 researchers estimate that while every year the oceans continue to sequester more anthropogenic carbon emission, the overall proportion of carbon taken in by the oceans is declining.
Coastal habitats may sequester 50 times more carbon than tropical forests by area
(11/16/2009) Highly endangered coastal habitats are incredibly effective in sequestering carbon and locking it away in soil, according to a new paper in a report by the IUCN. The paper attests that coastal habitats—such as mangroves, sea grasses, and salt marshes—sequester as much as 50 times the amount of carbon in their soil per hectare as tropical forest. "The key difference between these coastal habitats and forests is that mangroves, seagrasses and the plants in salt marshes are extremely efficient at burying carbon in the sediment below them where it can stay for centuries or even millennia."
Declaration calls for more wilderness protected areas to combat global warming
(11/11/2009) Meeting this week in Merida, Mexico, the 9th World Wilderness Congress (WILD9) has released a declaration that calls for increasing wilderness protections in an effort to mitigate climate change. The declaration, which is signed by a number of influential organizations, argues that wilderness areas—both terrestrial and marine—act as carbon sinks, while preserving biodiversity and vital ecosystem services.
Nations vulnerable to global warming present demands: carbon levels below 350ppm and billions in aid
(11/10/2009) A group of nations especially vulnerable to the effects of climate change have released a declaration calling for developed countries to keep CO2 emission below 350 parts per million (ppm) and to give 1.5 percent of their gross domestic product to aid developing nations in adapting to the myriad impacts of climate change.
