(01/21/2013) In Obama's second inauguration speech today, the newly re-elected president of the U.S. reaffirmed his commitment to taking action on climate during his second term. Noting that ignoring climate change would "betray our children and future generations," Obama argued whole-heartedly for a transition to clean energy.
Fish unable to pass through dams in U.S. presents 'cautionary tale' for developing world
(01/17/2013) Dams create a largely impenetrable barrier for fish even when the dams were installed with specially-built passages, according to a new study in Conservation Letters. The scientists found that migrating fish largely failed to use the passages in the U.S., resulting in far fewer moving through the state-of-the-art hydroelectric dams than had been promised. The researchers say that their findings are a "cautionary tale" for developing nations.
Presence of trees may mitigate cardiovascular and respiratory disease
(01/17/2013) Scientists with the U.S. Forest Service have observed a link between human health and trees, implying that trees may actually mitigate both cardiovascular and lower respiratory disease. Although the researchers do not yet put forward a reason why or how the presence of trees save lives, they are convinced there is a link.
Climate change already pummeling U.S. according to government report
(01/14/2013) Climate change is on the march across the U.S. according to a new draft report written by U.S. government scientists with input from 240 experts. It documents increasing and worsening extreme weather, rising sea levels, and ocean acidification among other impacts. Released Friday for public review, the report will be officially launched later this year or early in 2014.
Mercury hurts birds and people: what we can learn from studying our feathered friends
(01/07/2013) Birds aren't that different from people. We learn from our parents, just like zebra finches learn songs from their fathers. We are active and noisy during the day, like birds, and we can also be territorial. Also like birds, we try to attract mates through colorful displays and beautiful songs. Birds are sensitive to pollution in their environment just like we are: harmful elements such as mercury wreak similar havoc on human and bird biology alike. Because our species share so many attributes, studying birds illustrates the connections between them and us.
Mountain pine beetle threatening high-altitude, endangered trees
(01/02/2013) In the western U.S., few trees generally grow in higher altitudes than the whitebark pine (Pinus albicaulis). Providing shelter and food for bears, squirrels and birds, the whitebark pine ecosystems also help regulate water flow from snowmelt. But, according to a new study in the Proceedings of the National Academy of Sciences (PNAS), climate change has produced a novel threat for these high-altitude forests : mountain pine beetles (Dendroctonus ponderosae).
Arctic oil rig runs aground
(01/02/2013) On Monday night, an oil drilling rig owned by Dutch Royal Shell ran aground on Sitkalidak Island in southern Alaska, prompting fears of an oil spill. As of yesterday no oil was seen leaking from the rig according to the Coast Guard, but efforts to secure the rig have floundered due to extreme weather. The rig, dubbed Kulluk, contains over 140,000 gallons of diesel fuel.
Western scrub jay funerals...what's all the ruckus?
(12/10/2012) The western scrub jay (Aphelocoma californica) is a common denizen of suburban neighborhoods in the U.S., loitering at bird feeders and amusing bird watchers with their entertaining antics. Known to birders as 'WESJ,' this handsome bird is non-migratory and territorial during the breeding season, but what's curious about WESJ's is the way they respond to risks in their environment. When descended on by a predator or encountering a dead member of its kind, these birds hop from perch to perch and call loudly, ensuing in a 'cacophonous reaction,' a term coined by researchers at the University of California, Davis who are studying the behavior of these unique birds.
Greenpeace says U.S. logging company has broken landmark boreal forest agreement
(12/06/2012) When a long-fought peace was reached between nine environmental groups and 20 logging companies in 2010 for the vast Canadian boreal forest, it was dubbed the "world's largest conservation agreement." However, now that agreement is being shaken. A dispute between Greenpeace and U.S. logging company, Resolute Forest Products, over alleged logging in critical caribou habitat has resulted in the activist group abandoning the agreement.
Wealthy nations' fossil fuel subsidies dwarf climate financing
(12/05/2012) A new analysis finds that 21 wealthy countries spent five-times more on subsidizing fossil fuels in 2011 than they have on providing funds for poor nations to cut greenhouse gas emissions and adapt to the impacts of climate change. The analysis, by Oil Change International, comes in the midst of the current UN Climate Summit held in Doha, Qatar; progress at the talks has been stymied due to the gulf between poor and rich nations, including on the issue of climate financing.
'No-one is listening to the entire scientific community': global carbon emissions set to hit new high
(12/03/2012) Global carbon dioxide (CO2) emissions from industrial sources are set to hit a new record high this year according to a new analysis by Global Carbon Project. The analysis in Nature Climate Changes predicts that CO2 emissions will rise another 2.6 percent, hitting 35.6 billion tonnes. The scientists warn that such steep climbs in global emissions year-after-year means that the door is rapidly closing on a global agreement to keep temperatures from rising 2 degree Celsius (3.6 degrees Fahrenheit) above pre-industrial levels.
Hopes pinned on Obama again as Doha Climate Summit opens
(11/26/2012) A number of observers have expressed hope that the Obama Administration, fresh from a re-election victory in the U.S., will take a more active and ambitious role at this year's UN Climate Summit, held in Doha, Qatar. The summit opens amid fresh—and increasingly dire—warnings over climate change from the World Bank, the International Energy Agency, and the UN itself.
China and India plan 818 new coal plants
(11/26/2012) Even as the clamor to reduce greenhouse gas emissions reaches a new high—echoed recently by such staid institutions as the World Bank and the International Energy Agency (IEA)—a new analysis by the World Resources Institute (WRI) finds that 818 new coal-fired plants are under proposal in China and India. In all 1,199 new coal-fired plants are currently planned worldwide, according to the report, totaling 1.4 million megawatts of energy.
Climate activists march on White House again to oppose Keystone XL pipeline
(11/19/2012) Yesterday, climate activists marched around the White House in opposition against the Keystone XL pipeline, which if built will carry tar sands from Canada to the Gulf of Mexico and an international market. The protest, which included over 3,000 people according to organizing groups, is an opening salvo in activists' battle to convince the Obama Administration to turn down the pipeline for good.
BP fined $4.5 billion for Gulf of Mexico oil spill, but company may spend more buying its own stocks
(11/19/2012) Last week the U.S. federal government fined BP $4.5 billion for the Deepwater Horizon disaster in 2010, which killed 11 workers and leaked nearly 5 million barrels of oil into the Gulf of Mexico. The oil giant also plead guilt to 12 felonies and two misdemeanors. However, even this fine—the largest in U.S. history—failed to dampen shareholder support of BP: stocks actually rose one percent following the announcement. Meanwhile, according to the Sunday Times, BP plans to spend $5.9 billion (over a billion more than the fine) buying back its own shares in order to boost stock prices.
Obama criticized for lack of urgency on climate change
(11/15/2012) Following the devastation wrought by Hurricane Sandy—which many scientists say was likely worsened by climate change—and a long silence on the issue of global warming during the Presidential campaign, environmentalists yesterday were disappointed when re-elected President Barack Obama seemingly put action on climate change on the back burner.
House windows may kill 22 million Canadian birds each year
(11/15/2012) The sickening thud of a bird crashing into a window is an all-too-familiar sound for many Canadian homeowners. Birds often mistake windows for openings, flying into the glass at full speed. A startling new analysis suggests about 22 million Canadian birds die each year from such crashes, researchers reported Sept. 4 in Wildlife Research.
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.
Controversial wolf hunt moves to the Midwest, 196 wolves killed to date
(11/14/2012) The hugely controversial wolf hunt in the U.S. has spread from the western U.S. (Montana, Idaho, and Wyoming) to the Midwest (Minnesota and Wisconsin) this year. Although the wolf hunt is less than a month old in the region—and only eleven days old in Minnesota—196 animals so far have been shot. As in the west, the wolf hunt has raised hackles among environmentalists along with fierce defenders among hunters. Wolves, which were protected under the the Endangered Species Act (ESA) since 1973, were stripped of that status by legislation in 2009, opening the door—should a state choose—to trophy hunting.
It's not just Sandy: U.S. hit by record droughts, fires, and heatwaves in 2012
(11/05/2012) As the devastation wrought by Hurricane Sandy—killing over 100 people and producing upwards of $50 billion in damage along the U.S. East Coast—has reignited a long-dormant conversation on climate change in the media, it's important to note that this is not the only weird and wild weather the U.S. has seen this year. In fact, 2012 has been a year of record-breaking weather across the U.S.: the worst drought in decades, unprecedented heatwaves, and monster forest fires. While climatologists have long stated that it is not yet possible to blame a single extreme weather event on climate change, research is showing that rising temperatures are very likely increasing the chances of extreme weather events and worsening them when they occur.
New York Aquarium entirely 'underwater'
(10/30/2012) Hurricane Sandy, which brought storm surges that reached 14 feet to New York City, has put the Wildlife Conservation Society's New York Aquarium "under water," according to a statement from the organization. The aquarium is located on the Coney Island boardwalk, in the heart of an area where rescue operations are currently under way to save people stranded in their homes. There are reports that flooding has reached some people's roofs.
Hours before Hurricane Sandy hit, activists protested climate inaction in Times Square
(10/30/2012) On Sunday, as Hurricane Sandy roared towards the coast of the Eastern U.S., activists took to the streets in New York City to highlight the issue of climate change. Activists organized by 350.org unfurled a huge parachute in Times Square with the words, "End Climate Silence," a message meant to call attention to the fact that there has been almost zero mention of climate change during the presidential campaign, including not a single reference to the issue in the four presidential debates.
How climate change may be worsening Hurricane Sandy
(10/29/2012) While scientists are still debating some fundamental questions regarding hurricanes and climate change (such as: will climate change cause more or less hurricanes?), there's no debating that a monster hurricane is now imperiling the U.S. East Coast. A few connections between a warmer world and Hurricane Sandy can certainly be made, however: rising sea levels are likely to worsen storm surges; warmer waters bring more rain to increase flooding; and hotter temperatures may allow the hurricane to push both seasonal and geographic boundaries.
Future of the Tongass forest lies in salmon, not clear-cut logging
(10/25/2012) The Parnell administration's Timber Task Force recently unveiled a proposal to carve out two million acres of the Tongass National Forest for clear-cut logging under a state-managed "logging trust." The stated goal is to revive Southeast Alaska’s timber industry that collapsed two decades ago amid changing market conditions, logging cutbacks and evolving public opinion about timber harvesting on national forests.
New study adds to evidence that common pesticides decimating bee colonies
(10/24/2012) The evidence that common pesticides may be partly to blame for a decline in bees keeps piling up. Several recent studies have shown that pesticides known as "neonicotinoid" may cause various long-term impacts on bee colonies, including fewer queens, foraging bees losing their way, and in some cases total hive collapse. The studies have been so convincing that recently France banned the use of neonicotinoid pesticides. Now a new study finds further evidence of harm caused by pesticides, including that bees who are exposed to more than one chemical, i.e. neonicotinoid and pyrethroid, were the most vulnerable.
Lack of climate change in presidential debates part of larger trend
(10/23/2012) The final presidential debate between President Barack Obama and Governor Mitt Romney, focusing on foreign policy, ended like all the others: without a mention of climate change or its likely impacts on Americans, from rising sea levels to worsening extreme weather to the threat of instability abroad. While environmental groups have kicked-off a campaign to target this "climate silence," the lack of discussion on climate change is a part of a larger trend in the U.S. where media coverage of the issue has declined even as scientists argue that impacts are increasing.
By imitating human voices, beluga whale may have been attempting to communicate
(10/23/2012) Five years after the death of a captive beluga whale named NOC, researchers have discovered that the marine mammal may have been trying to communicate with people by mimicking humans voices at the National Marine Mammal Foundation in San Diego. Analyzing tapes of human-like speech from the young male beluga whale, scientists writing in Current Biology note that while there have been reports of beluga whales making human like sounds before, this is the first time evidence has been captured on tape and analyzed.
Cute animal picture of the day: baby walruses on the mend
(10/11/2012) Two walrus male calves were discovered over the summer near Barrow, Alaska, dehydrated and ill, after their separate mothers perished. The calves have been receiving care at the Alaska SeaLife Center, but one will soon be moved to the Wildlife Conservation Society's (WCS) New York Aquarium and the other to the Indianapolis Zoo.
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.
Nary a mention of climate change during U.S. presidential debate
(10/04/2012) The hour-and-a-half long debate between President Barack Obama and ex-governor Mitt Romney last night ended without a single reference to climate change. Frustrated with the lack of discussion on the issue from both candidates, environmental activists sent a petition with over 160,000 signatures to debate moderator, Jim Lehr, urging him to ask a question about climate change. The petition fell on deaf ears.
Jaguar conservation gets a boost in North and Central America
(09/27/2012) Jaguar conservation has received a huge boost in the past few months both in Latin America and in the U.S. An historic agreement singed between the world's leading wild cat conservation organization Panthera and the government of Costa Rica in addition to a new U.S. Fish and Wildlife Service (FWS) proposal bring renewed hope to the efforts to revive the iconic jaguar in its current habitat and return the cats to the American Southwest.
Corruption still plundering forests in Laos for furniture
(09/26/2012) The forests of Lao are still suffering from widespread destruction with the government turning a blind eye to a thriving black market logging trade on the border of Laos and Vietnam, according to an update report by the Environmental Investigation Agency (EIA). Last year, the EIA found that powerful players, including the Vietnamese military, were plundering Laos of its forests for raw logs. Smuggled from Laos into Vietnam, the raw logs are crafted into furniture, which are eventually exported to Europe and the U.S. Now, over a year later a new report finds little has changed.
Featured video: trailer for Living Downstream
(09/25/2012) After suffering from bladder cancer at 20, Sandra Steingraber began to study the links between toxic chemicals and deadly diseases. Her research led her to write the the much-acclaimed book Living Downstream, which combines her personal struggles with disease and the on-going contamination of our environment. Now, a new film based on the book, Steingraber's life, and the science behind cancer and chemicals in our environmental, is being released worldwide. To see the list of screenings worldwide: LIVING DOWNSTREAM.
Another mishap kills Shell's Arctic oil drilling for the year
(09/18/2012) Following global protests, a series of embarrassing mishaps, and a lengthy regulatory process, Dutch Royal Shell has announced it is abandoning its hugely controversial off-shore oil drilling in the Arctic—this year. The announcement came after the company damaged a containment dome meant to cap an oil spill. The incident was the latest in a series of delays and problems that oil the giant faced in its $4 billion plan to drill in the Chukchi and Beaufort Seas.
Extremely rare plant region left unprotected in the Yucatan Peninsula
(09/17/2012) For the first time, scientists have identified the areas of the Yucatan Peninsula that hold the highest concentrations of endangered woody plants, which includes trees, shrubs, and lianas. In doing so they uncovered four key regions, but also noted that the region with the highest concentration of extremely rare plants was left unprotected, according to a new paper in mongabay.com's open access journal Tropical Conservation Science.
NASA image shows why San Francisco is foggy
(09/12/2012) The short answer to why San Francisco, California is foggy? The Pacific Ocean's marine layer. A new image by NASA's Earth Observing-1 satellite shows the marine layer—cool, heavy air produced by a colder ocean surface meeting warmer air—encroaching on the metropolis. Western winds push the marine layer over the city, which brings dense cloud cover over the city, and often engulfs buildings, bridges, and people in fog.
Shell begins offshore drilling in the Alaskan Arctic
(09/10/2012) With the approval of the Obama Administration, Royal Dutch Shell began drilling into the ocean floor of the Chukchi Sea off the coast of Alaska yesterday morning. The controversial operation, which has been vehemently opposed by environmental and Native groups, will likely only last a few weeks this year until the Arctic winter sets in. The U.S. government has said that Shell must complete operations by September 24th, however the oil giant has asked for an extension.
Obama approves preparation for oil drilling in Arctic, Shell en route
(08/30/2012) In the same week that sea ice in the Arctic Ocean hit another record low due to climate change, the Obama Administration has given final approval to Royal Dutch Shell to prepare for exploratory drilling in the region. Vehemently opposed by environmentalists and indigenous groups, the drilling plans are a part of the Obama Administrations 'all of the above' energy policy. Whether or not Shell will actually drill a well this season, however, is still up in the air as its oil spill containment barge remains docked in Washington state for an upgrade that could last several days.
Chinook salmon return to Olympic National Park after dam demolished
(08/21/2012) In March of this year the Elwha Dam, which had stood for 99 years, was demolished in the U.S. state of Washington. Five months later, Chinook salmon (Oncorhynchus tshawytscha) made their way down 70 miles of long-blocked off habitat and entered Olympic National Park.
Pictures of the day: NASA captures stunning images of U.S. wildfires at night
(08/21/2012) NASA is now able to capture satellite images of wildfires—at night. Using the The Suomi National Polar-orbiting Partnership satellite (S-NPP), which has instruments that are particularly sensitive to light, NASA was able to take images of fires burning nocturnally across the American West in what has been a record year, to date, for fires in the country.
Shell running out of time to drill in U.S. Arctic - this year
(08/20/2012) The clock is running out for oil giant, Royal Dutch Shell, to drill controversial oil wells in the U.S. Arctic before the harsh winter sets in, reports the Wall Street Journal and Bloomberg. While the company is still optimistic it can reach the Arctic by summer's end, it awaits a number of final permits after suffering numerous setbacks, including one of its drilling ships going adrift and nearly running aground in Alaska.
Velociraptor spider discovered in Oregon cave (pictures)
(08/17/2012) Scouring the caves of Southwest Oregon, scientists have made the incredible discovery of a fearsome apex predator with massive, sickle claws. No, it's not the Velociraptor from Jurassic Park: it's a large spider that is so unique scientists were forced to create a new taxonomic family for it. This is the first new spider family to be discovered in North America in over 130 years. 'This is something completely new,' lead author of a paper on the species, Charles Griswold with the California Academy of Sciences, told SFGate. 'It's a historic event.'
United States ranks near bottom on first ever energy efficiency scorecard
(08/15/2012) Last month, the American Council for an Energy Efficient Economy released its first ever international energy efficiency scorecard, which gave the United Kingdom the top score. Using data points honed over years of rating U.S. states, the organization hoped to inspire nations to learn from each others' effective policies, as well as encourage "friendly competition" in the spirit of lowering global carbon emissions. At number one, the United Kingdom achieved a score of 67 out of 100 points, followed by Germany, Italy and Japan. As a whole, the European Union tied with China and Australia, and nine points below them, the United States came in with a score of 47 out of 100.
North American freshwater fish going extinct at rate over 800 times the fossil record
(08/14/2012) Since 1898 North America has lost at least 39 species of freshwater fish, according to a new study in Bioscience, and an additional 18 subspecies. Moreover, the loss of freshwater fish on the continent seems to be increasing, as the rate jumped by 25 percent since 1989, though even this data may be low.
July 2012: hottest month in U.S. history
(08/08/2012) Last month was not only the hottest July in U.S. weather history, but the hottest month ever recorded in the contiguous U.S, besting a record struck in July 1936 during the Dust Bowl, according to new data from the National Oceanic and Atmospheric Administration (NOAA). The average temperature last month over the contiguous U.S. was 77.6 degrees Fahrenheit, or 3.3 degrees Fahrenheit above the 20th Century average. Making matters worse, crippling drought continued to spread over 63 percent of the lower 48 states.
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.
Scientists testing anti-fungal bacteria on diseased frogs in California
(07/23/2012) Researchers are treating tadpoles in Kings Canyon National Park with a bacteria they hope will provide immunity to an infamous fungal disease, reports the San Francisco Gate. The bacteria could be key not only to saving California's mountain yellow-legged frog (Rana muscosa), which is listed as Endangered by the IUCN Red List, but also frog species around the planet, many of which have been decimated by the chytrid fungal disease.
