Report: Climate Changing More Rapidly Than At Any Point On Record

A new look at the “vital signs” of Earth’s climate reveals a stark picture of declining health. As global temperatures rise, so do sea level and the amount of heat trapped in the ocean’s upper layers. Meanwhile, mountain glaciers and Arctic sea ice are melting away beneath an atmosphere where concentrations of three key planet-warming greenhouse gases continue to rise.

“Data show that the climate is changing more rapidly now than it has at any time in the historical record,” says Thomas Karl, director of the National Oceanic and Atmospheric Administration’s (NOAA’s) National Climatic Data Center in Asheville, North Carolina. “The numbers speak for themselves.”
