Climate change is not expected to affect the extent or frequency of the El Niño/Southern Oscillation over the 21st century, but it could worsen its impacts. That’s the conclusion of a modeling study published in Journal of Climate in September.

New research by a team of scientists that includes NCAR’s Marika Holland takes a close look at making seasonal forecasts of Arctic sea ice coverage.

The unprecedented strength of both heat and drought across Texas has echoes in climate periods of the past and projections of the future.

Computer simulations point to ocean depths below about 1,000 feet as the main location for "missing heat."

The study underscores the complex and sometimes conflicting ways in which fossil fuel burning affects Earth’s climate.
