Rain, Storm Surge Combine to Put U.S. Coasts at Risk

Rain, Storm Surge Combine to Put U.S. Coasts at Risk

After the devastation of Hurricane Katrina, New Orleanians thought they knew what areas were susceptible to flooding during a storm. So when Hurricane Isaac, a much weaker storm than Katrina, bore down on the city in 2012, those who live to the west of Lake Pontchartrain weren’t worried, as they had been spared the raging waters that inundated so… 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

Record Hot First Half May Herald Warmest Year Yet

In what has become a monthly refrain this year, yet another month has set a global temperature record, with June 2015 coming in as the warmest June on record going back to 1880. It follows other record or near-record hot months during the first six months of this year, so there’s a good chance 2015 will take 2014’s place atop the podium as the warm… Read More

Arctic Sea Ice Volume Rebounds, But Not Recovering

Over the last few decades, and particularly in recent years, the area of the Arctic Ocean covered by a skin of sea ice has steadily shrunk. But it’s not just this extent that matters — the volume of sea ice, which takes into account its thickness, is also important, but traditionally much more difficult to measure. The 2010 launch of the European… Read More

Renewables Outpace Nuclear in Major World Economies

Renewables Outpace Nuclear in Major World Economies

Solar, wind and other forms of renewable energy besides hydro-electric dams now supply more electricity than nuclear in Japan, China, India and five other major economies accounting for about half the world's population, an atomic industry report shows.… Read More

Summer Nights Are Heating Up Across U.S.

Summer Nights Are Heating Up Across U.S.

Global warming often conjures scenes of sweaty, scorching summer days, but daytime temperatures aren’t the only thing expected to rise in a warming world. Nights, too, are expected to get sultrier, with overnight lows not dropping as much as they used to. That trend in increasing nighttime low temperatures is expected to continue for the entire … Read More
