New Island and Pumice Raft in the Tongas

Chilly Temperatures During the Maunder Minimum
Many things can change temperatures on Earth: a volcano erupts, swathing the Earth with bright haze that blocks sunlight, and temperatures drop; greenhouse gases trap heat in the atmosphere, and temperatures climb. From 1650 to 1710, temperatures across much of…
Paleoclimatology: Understanding the Past to Predict the Future
Scientists use complicated climate models to predict how Earth’s climate might change in the future. One of the best ways to test the reliability of such models is to see how well they recreate climates of the past.

Dust Storm off Alaska
A dust storm of glacial sediments blew off the Alaskan coast on November 1, 2006, almost exactly one year after a more intense dust storm blew out of the same spot: the Copper River Valley. The Moderate Resolution Imaging Spectroradiometer…
