Sea Level Rise May Eclipse 3 Feet By 2100, Study Finds

Sea Level Rise May Eclipse 3 Feet By 2100, Study Finds

The study adds to a growing body of evidence showing that the globe’s ice sheets in Greenland and Antarctica, which were once thought to have a slow and delayed response to climate change, are melting more rapidly, and becoming more vulnerable to crossing tipping points beyond which they may not quickly recover.… Read More

Why Bark Beetles are Chewing Through U.S. Forests

Why Bark Beetles are Chewing Through U.S. Forests

The conifer forests of the North American west have been under a massive assault over the past decade by bark beetles: one species alone, the mountain pine beetle, has killed more than 70,000 square miles’ worth of trees, equivalent to the area of Washington State, and two recent studies have shed some light on how climate change is helping fuel… Read More

Global Warming-El Nino Link Stronger but Still Not Proven

Global Warming-El Nino Link Stronger but Still Not Proven

The natural climate cycle known as the El Niño/Southern Oscillation (ENSO) would wreak havoc even if humans weren’t warming the planet. During its El Niño phase, the Americas get floods and torrential rains while Asia suffers drought. When it swings over to the La Niña phase, it’s the opposite. But humans are warming the planet, and a report … Read More

Climate Coverage Falls Further in 2012

Climate Coverage Falls Further in 2012

Widespread drought, super-storm Sandy, and a melting ice cap failed to revive the media's interest in climate change in 2012, with worldwide coverage continuing its three-year slide, according to a media database maintained by the nonprofit journalism site The Daily Climate. The decline in the number of stories published on the topic – 2.4 percent… Read More

Radiocarbon Dating: Nature’s Timepiece Gets a Tune-Up

Radiocarbon Dating: Nature’s Timepiece Gets a Tune-Up

It’s relatively easy for scientists to see the signature of droughts and other climate events in the prehistoric past by looking digging into underground or seafloor sediments, or drilling into ancient ice. In order to say exactly when these events happened, though, you need a reliable natural dating method, and even the best of these is flawed. On… Read More

Great Lakes Legacy Contaminants Fall, Newer Ones Rise

Great Lakes Legacy Contaminants Fall, Newer Ones Rise

Legacy contaminants are decreasing more quickly than previously reported in three of the Great Lakes, but have stayed virtually the same in two other lakes, according to new research. “These are very positive results. The lakes are improving and slowly cleaning themselves up,” said Thomas Holsen, co-director of Clarkson University’s Center for the … Read More

Sandy Tops List of 2012 Extreme Weather & Climate Events

Sandy Tops List of 2012 Extreme Weather & Climate Events

From unprecedented heat waves that shattered "Dust Bowl" era records from the 1930s, to Hurricane Sandy, which devastated coastal New Jersey and New York, 2012 was the year Mother Nature had it out for the U.S. No country on Earth rivaled the U.S. in 2012 in terms of extreme weather and climate events, as one rare episode after another rocked the c… Read More

Coal to Challenge Oil’s Dominance by 2017, Says IEA

Coal to Challenge Oil’s Dominance by 2017, Says IEA

Coal is likely to rival oil as the world's biggest source of energy in the next five years, with potentially disastrous consequences for the climate, according to the world's leading authority on energy economics. One of the biggest factors behind the rise in coal use has been the massive increase in the use of shale gas in the U.S. … Read More
