The future pattern of population growth, not climate change, is likely to be the dominant factor in determining whether the amount of land burned by fires increases or decreases globally this century.

The ORCAS field project records carbon dioxide levels exceeding 400 ppm over one of the remote regions of the globe.

A reduction in the amount of oxygen dissolved in the oceans due to climate change should be evident across large parts of the ocean between 2030 and 2040.

Hosted at NCAR, the program brings scientists and engineers together with Native American community members to build bonds and discuss ways to adapt to a changing climate.
