Blistering Future Summers for 1,001 U.S. Cities

Blistering Future Summers for 1,001 U.S. Cities

During these dog days of summer, air conditioning and splash parks can help beat the heat, but climate change is making it harder to avoid simmering temperatures. Summers in most of the U.S. are already warmer than they were in the 1970s. And climate models tell us that summers are going to keep warming as greenhouse gas emissions continue. What … Read More

Derailments May Increase as ‘Sun Kinks’ Buckle Tracks

Derailments May Increase as ‘Sun Kinks’ Buckle Tracks

Railroads could see more sun kinks if climate change-related heat waves become more severe and more frequent, possibly leading to train derailments. Sun kinks have been a major cause of derailments in recent decades, but scientists fear they could become more common in a warming world.… Read More

Using CO2 Emissions to Pump Oil May Help the Climate

Using CO2 Emissions to Pump Oil May Help the Climate

Called “carbon dioxide enhanced oil recovery,” the process works like this: CO2 emissions are captured from coal-fired power plants, then transported to old oil fields where production peaked long ago. By injecting the captured CO2 into existing oil wells that have been producing diminishing amounts of crude oil, hard-to-get crude oil will react wi… Read More

Waiting to Slash CO2 Emissions? It Could Cost You

Waiting to Slash CO2 Emissions? It Could Cost You

The cost of the U.S. delaying action on climate change by reducing carbon dioxide emissions could increase 40 percent each decade if no action is taken, according to a Council of Economic Advisers report released by the White House on Tuesday.… Read More

Warming Threatens Roads, Ports and Planes, Report Says

Warming Threatens Roads, Ports and Planes, Report Says

The transportation sector is a major contributor to climate-changing carbon dioxide emissions, it’s also one of the most vulnerable sectors to the effects of climate change. That means “sun kinks” could warp train tracks in the heat, and airplanes will be pricer to fly.… Read More

Court Ruling May Reverberate on ‘Social Cost’ of Carbon

Court Ruling May Reverberate on ‘Social Cost’ of Carbon

Greenhouse gas emissions from burning and extracting coal, oil and natural gas drive climate change, and as communities feel the effects of a warming world — rising seas, burning forests and withering crops — communities’ pocketbooks take a hit, too.… Read More
