Carbon Emissions From Power Plants Hit 27-Year Low

Carbon Emissions From Power Plants Hit 27-Year Low

As states begin the long task of reducing greenhouse gas emissions from electric power plants to comply with new federal climate policy, a 27-year low in carbon dioxide emissions earlier this year shows the U.S. may be heading toward meeting its emissions goals. U.S. power plants emitted less carbon dioxide — 128 million metric tons — in April … Read More

White House: Efficiency Key to Tackling Climate Change

White House: Efficiency Key to Tackling Climate Change

As a way to help homeowners act on climate change locally, the White House on Monday announced a series of clean energy policies meant to increase the energy efficiency of homes and make rooftop solar installations accessible without a huge outlay of money. The Obama administration, as part of its Clean Power Plan, has highlighted energy … Read More

Study: China May Have Overestimated Carbon Emissions

Study: China May Have Overestimated Carbon Emissions

Carbon dioxide emissions in China may have been overestimated since 2000 because of conflicting estimates of the greenhouse gas emissions it produces and the carbon content of the coal it burns, a Harvard-led study published Wednesday shows. Overestimated emissions may be critical for China ahead of the upcoming Paris climate negotiations in … Read More

EPA Moves to Cut Oil and Gas Methane Emissions

EPA Moves to Cut Oil and Gas Methane Emissions

The Environmental Protection Agency on Tuesday proposed new rules meant to help combat climate change by curbing methane emissions from new hydraulically fractured crude oil wells and natural gas pipelines and other infrastructure. The measure, part of the Obama administration’s Climate Action Plan, seeks to cut methane emissions from the oil and … Read More

Surging Renewables Frame EPA’s Historic Climate Rules

Surging Renewables Frame EPA’s Historic Climate Rules

In its signature bid to reimagine America’s power infrastructure to help slow climate change, the Obama Administration has ratcheted up its demands and expectations for pollution reductions from America’s electricity sector for the years ahead. Pointing to recent projections for rapid advances in renewable energy and energy efficiency technologies,… Read More

Fossil Fuels May Bring Major Changes to Carbon Dating

Fossil Fuels May Bring Major Changes to Carbon Dating

Radiocarbon dating has been helping put the planet’s history in the right order since it was first invented in the 1940s, giving scientists a key way to determine the age of artifacts like the Dead Sea Scrolls and the Shroud of Turin. Thanks to fossil fuel emissions, though, the method used to date these famous artifacts may be in for a change. … Read More

Stagnant Summer Days on the Rise in U.S.

Stagnant Summer Days on the Rise in U.S.

Those long, hot, sultry days of summer, the ones where the air seem so still it wouldn’t disturb a leaf, are also days where air quality can take a nosedive. With winds barely above a whisper and atmosphere-scouring rains nowhere in sight, pollutants can build up in the air we breathe, with potentially serious health consequences. Since climate… Read More

New Grants Fund Research for Underseas Carbon Storage

New Grants Fund Research for Underseas Carbon Storage

As scientists seek ways to control greenhouse gas emissions to slow climate change, the federal government is on a mission to prove whether rock formations deep beneath the Atlantic Ocean can be used to store and lock away human carbon dioxide emissions. The U.S. Department of Energy, which has been researching carbon dioxide storage for years … Read More
