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

Recession Caused U.S. Emissions Drop, Study Says

Recession Caused U.S. Emissions Drop, Study Says

An ongoing move from coal to natural gas to generate electricity has been considered one of the primary reasons for a tumble in carbon dioxide emissions in the U.S. between 2007 and 2012, but a new study has found that the falling emissions were more likely caused by an overall drop in consumption during the Great Recession. … Read More

Gap Seen Between Federal Climate Policy, Coal Leasing

Gap Seen Between Federal Climate Policy, Coal Leasing

At a time when climate scientists are warning with increasing urgency that many fossil fuel resources must be left in the ground, the federal government is leasing publicly-owned land and minerals for coal mining at an increasing rate, especially in Wyoming, Colorado and Utah. It’s happening even as the White House finalizes the Clean Power Plan … Read More

States Cut Power Plant Emissions Ahead of New EPA Rule

States Cut Power Plant Emissions Ahead of New EPA Rule

Forty-two states are reducing carbon dioxide emissions from power plants on their own as they move toward using less coal and more natural gas to produce electricity. Between 2008 and 2013, those states reduced greenhouse gas emissions from electric power plants by an average of 19 percent, according to a report published Tuesday.… Read More

Study: Warming Leads to Longer Flights, More Emissions

Study: Warming Leads to Longer Flights, More Emissions

Climate change is causing wind patterns to change over the Pacific Ocean, leading to longer commercial airline flight times and causing airplanes to burn more fuel and emit more greenhouse gases. Those are the conclusions of a Woods Hole Oceanographic Institution study published Monday in the journal Nature Climate Change, showing that the … Read More

Mountaintop Coal Falls As Renewables, Natural Gas Rise

Mountaintop Coal Falls As Renewables, Natural Gas Rise

Coal country in West Virginia and eastern Kentucky is riddled with flattened mountain tops and valleys filled in with the rocks and debris that once formed the peaks high above. Mountains blasted from the central Appalachian landscape are signs that the coal industry is at work supplying fuel for electric power plants throughout the region … Read More
