White Roofs May Partially Offset Summer Warming by 2100

White Roofs May Partially Offset Summer Warming by 2100

Painting building roofs white could cool some major cities baking in the intensifying heat of a changing climate. How much benefits white roofs could bring depend on the region of the country they’re installed in and the season, new research shows. Keeping cities cool in the summer is becoming increasingly important as more people move to urban ar… Read More

Snowmakers Save Ski Season in Warming World, For Now

Snowmakers Save Ski Season in Warming World, For Now

When Aaron Sherritt took a job as a ski instructor at a hill near his parents' home to make some extra money during college break, he didn't think much about how the snow under his skis got there. Fifteen years later, it's all he thinks about. As snowmaking supervisor at Wachusett Mountain, it's his job make sure the slopes are cloaked in white c… Read More

Watch 63 Years of Global Warming in 14 Seconds

Updated to include 2013, this 14-second animation from our friends at NASA depicts how temperatures around the globe have warmed since 1950. You’ll note an acceleration of the temperature trend in the late 1970s as greenhouse gas emissions from energy production increased worldwide and clean air laws reduced emissions of pollutants that had a … Read More

Time is Running Out for California Drought Relief

Time is Running Out for California Drought Relief

More than halfway through the state's wet season and the Sierra Nevada snowcap all but non-existent, California's prospects for making up its precipitation deficit are slim. The snowcap will yield precious little water and the state would need to get about a foot or more of rain in the next two months to make up the difference. Forecasts are not of… Read More

Climate Change Cuisine: It’s What’s for Dinner

Climate Change Cuisine: It’s What’s for Dinner

Living in Ames, Iowa, Steven Cannon is no stranger to the Midwestern potluck. Instead of a potato-chip-capped casserole, however, Cannon serves up “potato beans” fried in duck fat or simmered in south Indian spices. Either way, he says the smooth-textured starch, hinting of boiled peanut flavor, is always a hit. The potato bean, also called groundn… Read More

Dams May Provide Resilience to Climate Change

Dams May Provide Resilience to Climate Change

It’s official: Last year was Australia’s hottest on record. As temperatures go up Down Under, so do concerns about how to keep rivers cool in a warming world. Ironically, the soundest solution could mean tapping into what has long been considered a pollutant. Until recently, scientists only studied how cold water releases from dams can send a therm… Read More
