Sweltering heat waves that typically strike once every 20 years could become yearly events across 60 percent of Earth's land surface by 2075.

The planet is effectively three-quarters of the way to the limit set by world leaders of 2 degrees Celsius of warming.

The weather patterns that typically bring moisture to the southwestern United States are becoming more rare, an indication that the region is sliding into a drier climate state.

A global weather model developed at NCAR offers a new way of simulating the atmosphere while providing scientists with flexibility when focusing on a specific area.

The new system for the NCAR-Wyoming Supercomputing Center will be capable of more than three times the amount of scientific computing performed by its predecessor.
