New Ways to Visualize Increasingly Hot Weather in U.S.

New Ways to Visualize Increasingly Hot Weather in U.S.

The portion of days with warm weather in the U.S. have increased by 25 percent over the past 50 years according to a new data analysis. The analysis draws on publicly available data and represents the tip of the iceberg for how publicly available climate and weather data can be accessed and used. New York-based open data firm Enigma unde… Read More

Carbon Capture Faces Hurdles of Will, Not Technology

Carbon Capture Faces Hurdles of Will, Not Technology

The IPCC calls for carbon capture and storage technology to be used to reduce CO2 concentrations in the atmosphere to prevent the worst consequences of climate change from occurring. Scientists say the technology is ready, but there is no incentive to build carbon sequestration projects.… Read More

Climate Models, Globe’s Oceans Put Stamp on Earth Day

Climate Models, Globe’s Oceans Put Stamp on Earth Day

For the stamp collector in search of an accurate portrayal of the globe’s oceans, look no further than the new U.S. Postal Service international Forever stamp. Released to commemorate Earth Day, the stamp features a snapshot of how high-tech climate models depict oceans. The Postal Service has a citizen advisory committee (who knew?) that looks fo… Read More

‘Oldest Living Things in the World’ Tell a Tale of Climate

‘Oldest Living Things in the World’ Tell a Tale of Climate

The spindly trunk of a Norway spruce reaches above the lichen-covered rocks. Nothing about the tree is remarkable aside from it being the only thing to reach more than a foot feet off the ground on a windswept plateau. Yet Rachel Sussman traveled the roughly 3,500 miles from her Brooklyn studio to western Sweden to photograph it. Its age is what d… Read More

April Will Be First Month With CO2 Levels Above 400 PPM

April Will Be First Month With CO2 Levels Above 400 PPM

April will be the first time in human history where levels of atmospheric carbon dioxide were higher than 400 parts per million for an entire month, one scientist who monitors the levels said. And they could stay above that mark into July. Carbon dioxide concentrations, as measured at a site atop Hawaii’s Mauna Loa volcano since 1958, surpassed… Read More

Hot West, Cold East May be the Norm as World Warms

Hot West, Cold East May be the Norm as World Warms

The split personality of this winter’s weather in the U.S. appears to have been thousands of years in the making. The big driver behind the frigid-East and warm-West divide was a kinky jet stream, a pattern that arose 4,000 years ago. While natural variations have controlled its wanderings to date, climate change could make the duality we saw this … Read More

U.S. State Department Delays Keystone XL Decision

The U.S. State Department is delaying its decision on whether to approve the controversial Keystone XL Pipeline to give federal agencies more time to review the proposal. The delay could push the Keystone XL decision beyond the November midterm elections.… Read More

U.S. GHG Emissions at Lowest Level in 20 Years

U.S. GHG Emissions at Lowest Level in 20 Years

U.S. greenhouse gas emissions declined 3.4 percent in 2012 from 2011, the Environmental Protection Agency announced Tuesday. Those emissions are down 10 percent from what they were in 2005, the EPA said. Most of the decline came from reductions in energy consumption, increased fuel efficiency of cars and other types of transportation, and a shift… Read More
