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

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

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

Cities ‘Woefully Unprepared’ for Rising Disaster Risk

Cities ‘Woefully Unprepared’ for Rising Disaster Risk

Cities around the world are failing to plan for fast-increasing risks from extreme weather and other hazards, particularly as population growth and surging migration put more people in the path of those threats, the World Bank said. By 2050, 1.3 billion people and $158 trillion in assets will be menaced by worsening river and coastal floods alone… 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

Sea Level Rise Could Help Marshes Ease Flooding

Sea Level Rise Could Help Marshes Ease Flooding

Along the mid-Atlantic coast, where waters are rising quickly, marshes are on the march, consuming forestland, farms and yards. “Habitats are changing fast here,” said Matt Whitbeck, a biologist at the Blackwater National Wildlife Refuge in Maryland, where dead trees still jut from young marshes. Newly published modeling shows that a looming… Read More

Young Forests Can Store ‘Enormous’ Amounts of Carbon

Young Forests Can Store ‘Enormous’ Amounts of Carbon

Woodland areas that regrow after forest fires, logging operations or other disturbances can sequester huge amounts of carbon dioxide and they play an unexpectedly valuable role in mitigating climate change, according to a study by 60 scientists from across the globe. The research, published Friday in the journal Science Advances, is the first to … Read More

EPA Moves to Regulate Oil and Gas Methane Emissions

EPA Moves to Regulate Oil and Gas Methane Emissions

The Obama administration announced new rules on Thursday aimed at cutting methane emissions from new oil and gas wells and fracking operations. The rules also will require energy companies to provide pollution information to the Environmental Protection Agency so it can regulate methane emissions from existing oil and gas wells. Methane warms the … Read More

Global 2040 Forecast Sees Only Slight Fall in Fossil Fuels

Global 2040 Forecast Sees Only Slight Fall in Fossil Fuels

Despite the urgency to cut greenhouse gas emissions as climate change bears down on the globe, fossil fuel use is not likely to change much in the coming decades. Though renewable energy will grow quickly though 2040, gasoline and diesel will still move most of the world’s vehicles, and coal will still be the largest single source of carbon … Read More
