New Tar Sands Impact on Climate, Air Quality Found

New Tar Sands Impact on Climate, Air Quality Found

In one of the first studies of its kind, scientists have found that tar sands production in Canada is one of North America’s largest sources of secondary organic aerosols — air pollutants that affect the climate, cloud formation and public health. The study, published Wednesday in the journal Nature, showed that the production of tar sands and … Read More

Acidifying Waters Put Dungeness Crabs at Risk

Acidifying Waters Put Dungeness Crabs at Risk

Research published this month could give a crab connoisseur a case of acid reflux. Scientists reported in the journal Marine Biology that ocean acidification, which is caused when carbon dioxide pollution dissolves into oceans, can kill and stunt young crabs, potentially jeopardizing whole populations. “It’s something that’s projected into the … Read More

U.S. Leads Globe in Oil Production for Third Year

The U.S. led the world last year in producing both oil and gas, federal government estimates published Monday show, even as the country committed to cutting greenhouse gas emissions. … Read More

Abrupt Atlantic Ocean Changes May Have Been Natural

Abrupt Atlantic Ocean Changes May Have Been Natural

Climate change may not have been to blame for an abrupt recent slowdown of a sweeping Atlantic Ocean current, a change that delivered an intense pulse of ocean warming and sea level rise through the Gulf of Maine and elsewhere along the East Coast. Modeling-based analysis by British scientists, published Monday in Nature Geoscience, concluded that … Read More

Global Warming Will Hit Poorer Countries Hardest

Global Warming Will Hit Poorer Countries Hardest

New evidence that poorer countries will suffer the worst effects of climate change has shown that the number of hot days in tropical developing countries is likely to increase markedly as global warming takes hold. It has long been expected that poor people would bear the brunt of climate change, largely because so many more of the world’s poorest … Read More

‘99 Percent Chance’ 2016 Will Be Hottest Year

‘99 Percent Chance’ 2016 Will Be Hottest Year

Odds are increasing that 2016 will be the hottest year on the books, as April continued a remarkable streak of record-warm months. Last month was rated as the warmest April on record by both NASA and the National Oceanic and Atmospheric Administration, which released their data this week. In the temperature annals kept by NOAA, it marked the 12th … Read More

Power Plant Emissions Fall to Lowest Level in Decades

Power Plant Emissions Fall to Lowest Level in Decades

Carbon dioxide emissions from electric power plants have fallen to their lowest level in decades, and that trend could help states meet their emissions goals under the Obama administration’s Clean Power Plan if it survives court challenges, according to new U.S. Energy Information Administration data and a New York University analysis. Carbon … Read More

Marine Parks Help Global Fish Stocks Withstand Warming

Marine Parks Help Global Fish Stocks Withstand Warming

New and expanded marine parks and fishing rules could be powerful antidotes for threats of famine as fisheries dwindle from climate change and overfishing, new research has shown. An ambitious new analysis of big marine data produced from thousands of dives by citizen scientists has detected a powerful link between the biodiversity of a … Read More
