As temperatures warm across much of the globe, how often will people be threatened by extreme heat and extreme air pollution happening at the same time?

A hypothetical nuclear war between India and Pakistan could kill 50-125 million people in the two nations in less than a week, according to new research.

NCAR has started to generate high-resolution experimental, 48-hour forecasts of air pollutants across the contiguous United States.

Residents of New Delhi and nearby heavily polluted areas of northern India now have access to air quality forecasts that provide critical information for reducing their exposure to potentially unhealthy air.

NCAR supported research to efficiently measure methane and associated chemicals in the atmosphere.
