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

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

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

One in Five of World’s Plant Species at Risk of Extinction

One in Five of World’s Plant Species at Risk of Extinction

One in five of the world’s plant species is threatened with extinction, according to the first global assessment of flora, putting supplies of food and medicines at risk. But the report also found that 2,000 new species of plant are discovered every year, raising hopes of new sources of food that are resilient to disease and climate change. New … 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

Fracking Hits Milestone as Natural Gas Use Rises in U.S.

Fracking Hits Milestone as Natural Gas Use Rises in U.S.

More natural gas in the U.S. is coming from wells that have been hydraulically fractured than ever before, and fracking’s share of the country’s gas supply is continuing to rise, according to new data from the U.S. Energy Information Administration. At the same time, the fracking boom in the U.S. has led to a major boost in natural gas consumption… Read More
