The Human Fingerprints on Coastal Floods

The Human Fingerprints on Coastal Floods

There are human fingerprints on thousands of U.S. coastal floods — and countless more the world over. We have known for a long time that sea level is rising. The link to global warming has been both intuitive and evident. Temperatures rise, and satellites watch glaciers and ice sheets shrink; networks of robotic buoys sample ocean waters as they … Read More

Every State’s Temperature Trend for Every Season

Every State’s Temperature Trend for Every Season

A winter heat wave is spreading inland from the West Coast and could bring unseasonable warmth spanning from coast-to-coast by the weekend. Southern California is on track to continue setting hot temperature records, Phoenix will have its earliest first 90°F day of the year, and parts of the South could see temperatures 20°-30°F above normal … Read More

2° Challenge: Try to Avoid Disastrous Climate Change

2° Challenge: Try to Avoid Disastrous Climate Change

There’s one goal of international climate change negotiations: Stop warming short of 2 degrees. At 2 degrees Celsius of warming, low-lying island nations are expected to be under water, droughts and storms will become supercharged and a third of species may be put at risk for extinction. Not to mention the increased risk of deadly heat waves. It’s … Read More

U.S. Cities We Could Lose to the Sea

Historic carbon emissions have already locked in enough future sea level rise to submerge most of the homes in each of several hundred American towns and cities, according to Climate Central-led research published Monday in Proceedings of the National Academy of Sciences. The animated timeline on this page maps, year by year, how the total number … Read More

Obama Just Created a Carbon Cap-and-Trade Program

Obama Just Created a Carbon Cap-and-Trade Program

As the Obama Administration honed its historic new climate rules affecting power plants, it began thinking about electricity more broadly. It was a shift in perspective that in the end may produce the nation’s newest system for trading pollution. Instead of looking solely at how each state could reduce pollution from its electricity sector, the… Read More

Water Use Declining as Natural Gas Grows

Water Use Declining as Natural Gas Grows

As the U.S. has undergone a rapid and massive shift to natural gas from coal, one benefit has gone almost entirely overlooked: the amount of water needed to cool the nation’s power plants has dropped substantially. The widespread adoption of hydraulic fracturing (fracking) technology has led to dramatically higher natural gas production in the … Read More

U.S. Summers Bringing More and More Heat

It’s officially summer! We have now passed the points that mark the traditional start to summer (Memorial Day), the meteorological start (June 1), and now the astronomical start, or summer solstice (June 21) — so break out those flip-flops and beach towels! Though June, July, and August usually bring the heat, for parts of the country spring felt … Read More
