The Arctic is one place that’s been hit particularly hard by climate change. Now a new study has shown that the Arctic is beginning to transition into an entirely new climate state, leaving its predominantly frozen state behind.

A solar eclipse might darken the day for minutes, but 65 million years ago the sun may have disappeared for 18 months. New simulations show that atmospheric particles would have blocked sunlight, disrupting plants' photosynthesis and cascading into a mass extinction event.

Arctic temperatures in the 1990s reached their warmest level in 2,000 years, new research indicates. The study provides new evidence that the Arctic would be cooling if not for greenhouse gas emissions that are overpowering natural climate patterns.

An international team of scientists led by the National Center for Atmospheric Research (NCAR) has created the first-ever comprehensive computer model of sunspots.

A team of UC San Diego-led atmospheric chemistry researchers have detected biological particles within ice clouds leading to the discovery that not only mineral dust but also biological particles play a major role in the formation of clouds.

The National Center for Atmospheric Research (NCAR) has announced the arrival of AMSTAR, a new digital storage library that will preserve and protect 30 petabytes of valuable scientific data for the next 15 to 20 years.
