Warming-Driven Glacier Melt Leads to ‘River Piracy’

Warming-Driven Glacier Melt Leads to ‘River Piracy’

In the summer of 2016, the global warming-induced retreat of Kaskawulsh Glacier — one of the largest glaciers in Canada — altered the flow of its meltwater so substantially that it killed off one river and shunted its waters over to another, an abrupt geological act known as river piracy. A team of researchers were serendipitously on hand to… Read More

Since the first Earth Day was celebrated 46 years ago, in 1970, average temperatures across the U.S. have been steadily rising. This Climate Central interactive graphic shows a state-by-state analysis of those temperature trends. Across most of the country, average temperatures have increased at a rate of about 0.13°F (0.07°C) per decade since … Read More

Flirting with the 1.5°C Threshold

Flirting with the 1.5°C Threshold

Global leaders are meeting in New York this week to sign the Paris climate agreement. One of the expressed purposes of the document is to limit warming to “well below 2°C above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5°C.” A Climate Central analysis shows that the world will have to dramatically accelerate… Read More

Meltdown: More Rain, Less Snow as the World Warms

Meltdown: More Rain, Less Snow as the World Warms

As the world warms, the meaning of winter is changing. In the U.S., a greater percentage of winter precipitation is falling as rain, with potentially severe consequences in western states where industries and cities depend on snowpack for water, and across the country wherever there is a winter sports economy. A Climate Central analysis of 65 … Read More

How a Monster El Niño Transforms the World’s Weather

How a Monster El Niño Transforms the World’s Weather

From crippling drought in southern Africa to a record number of February tornadoes in the U.S. Southeast, an exceptionally strong El Niño has been making headlines around the globe as it tampers with the world’s weather. While the event has begun its slow decline, those wide-ranging impacts will continue to be felt for weeks and months to come … Read More

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
