Study: Glacial Lakes Appearing in Antarctica

Antarctica is home to Earth’s largest ice mass, which unlike the Arctic remains frozen year round. But a new satellite-based study in the journal Geophysical Research Letters shows that atop the coastal Langhovde Glacier in East Antarctica’s Dronning Maud Land, large numbers of meltwater lakes have been forming. The study suggests that the lakes—nearly 8,000…

Diving Deep Below Arctic Ice to Bring Back Our Ocean’s Skeletons: #bestjobever

Polar expeditions to explore the ocean are not for the faint of heart. Above the water’s surface, you better be on alert for polar bears. Below, you better be game for diving 60 feet under sea ice into freezing temperatures. Watch National Geographic grantee Branwen Williams lead a team to the Canadian Arctic to do both in an effort to better understand how our oceans and the climate are changing over time.

Americans View of Climate Change Polarized; U.N. Targets May Be Tough to Achieve

Surveys conducted by Yale University and George Mason University suggest that 17 percent of Americans view climate change as an alarming threat and that another 28 percent are concerned about climate change but view it as a distant threat. The subject has become highly contentious since 1997, when then Vice President Gore helped broker an…

Volcanic Eruption Affects Sea Level Rise

A new study in the journal Scientific Reports suggests that the evidence to pinpoint expected acceleration of sea-level rise due to climate change was hiding behind the effects of a 1991 eruption of Mount Pinatubo. This eruption sent tens of millions of tons of sulphur dioxide into the stratosphere and may have masked the effects of industrial…

New York Joins Handful of Other States with Ambitious Clean Energy Targets

By 2030, half of the energy produced in the state of New York will come from renewables, according to a new policy adopted Monday by the state’s public service commission. The move is expected to reduce greenhouse gas emissions by 40 percent from 1990 levels (80 percent by 2050) and to attract billions in clean…

Pending Deal on Montreal Protocol Amendment Second Only to Paris Agreement

World climate leaders meeting in Vienna have laid the foundation for an amendment to the 1987 Montreal Protocol, the global treaty that phased out ozone-depleting chlorofluorocarbons (CFCs). The amendment would address climate-damaging hydrofluorocarbons (HFCs), the refrigerant chemicals that replaced CFCs but that can trap heat in the atmosphere at levels a thousand times higher than…

Urgent Global Action Needed to Stop Extinction of Earth’s Last Megafauna

A swift and global conservation response is needed to prevent the world’s gorillas, lions, tigers, rhinos, and other iconic terrestrial megafauna from being lost forever, an influential group of international scientists reported today in the journal BioScience.

Their analysis, entitled Saving the World’s Terrestrial Megafauna, covers the precipitous loss of large animal populations around the globe. The report included a 13-point declaration by 43 scientists and conservationists calling for acknowledgement that a “business as usual” mentality will result in massive species extinction. Read the declaration and study the maps showing the global decline of big land animals.

Survey, Party Platforms Reveal Deep Divide on Climate Change

In March, the Guardian issued an election-related call-out to online readers in the United States, asking them to identify the “one issue that affects your life you wish the presidential candidates were discussing more.” The results are in. Of the 1,385 respondents from all 50 states, one in five expressed discontent about lack of discussion…

Cecil the Lion one Year on: An Interview with Cecil’s Researcher

A year ago, a male lion called Cecil was killed in Hwange National Park, Zimbabwe, by an American trophy hunter. Cecil’s death caused uproar around the world and shone a much-needed light on the decline and vulnerability of the African lion population; today, there may be no more than 20,000 remaining in the wild. To…

Natural Fluctuations Responsible, in Part, for Antarctica Ice Growth

Natural fluctuations specifically related to the Interdecadal Pacific Oscillation (IPO) are responsible for the increased growth of Antarctic sea ice, according to a new study in the journal Nature Geoscience. A negative shift in the IPO has caused cooler-than-average sea surface temperatures in the Eastern Pacific, allowing Antarctic sea ice to expand since 2000. “The…

North American Leaders Commit to Clean Energy Goal

At the North American Leaders Summit on Wednesday, Mexico, Canada and the United States pledged to generate 50 percent of their energy from clean sources by 2025. The joint commitment by the three countries, according to White House Adviser Brian Deese, is “an aggressive goal” but one that is “achievable continent-wide.” “The Paris Agreement was…

Coral Reef Bleaching Event Forecast to Worsen; NASA Studies Cause in Pacific

Coral in every major reef region across the world has already experienced bleaching, and the National Oceanic and Atmospheric Administration (NOAA) forecasts that temperatures in much of the Pacific, Atlantic and Indian oceans could reach a point at which significant bleaching of corals is present this summer. NOAA’s Coral Reef Watch suggests that the greatest…

It’s Catching, If You’re a Clam: Infectious Cancer Spreading in Soft-Shell Clams, Other Mollusks

It sounds like the plot of a summer horror flick: Malignant cells floating in the sea, ferrying infectious cancer everywhere they go. The story is all too true, say scientists who’ve made a discovery they call “beyond surprising.” Outbreaks of leukemia that have devastated populations of soft-shell clams (Mya arenaria) along the east coast of…

If payers don’t sway players, what does funding tell you?

Several people have objected to the recent piece here by me and Greenpeace’s John Hocevar, so I am following up with this. That earlier piece explained a complaint by Greenpeace alleging that fisheries scientist Ray Hilborn has often not properly disclosed industry funding in his scientific publications. The people writing in to object to that piece…

Big Black Bears Celebrated in Big Way in Washington County, North Carolina

On a recent spring morning, photographer Doward Jones and a friend were looking for photo opportunities in the Pocosin Lakes National Wildlife Refuge near Plymouth, North Carolina. As they cruised through the refuge in an SUV, they spotted a black bear helping himself to wheat in a farmer’s field. The young male bear was enjoying…
