In October 2003, a little-known think tank in the Department of Defense quietly released a report warning that climate change could happen so suddenly it could pose a major threat to our country's national security. Why was the Pentagon worried about abrupt climate change? Because new evidence from Greenland showed it had happened before.
Working with private companies, the U.S. Department of Agriculture’s Risk Management Agency uses precipitation data from NOAA’s Climate Prediction Center as part of an insurance program for ranchers and those who grow hay or other livestock forage. This video describes how it works.
Although you might have a hard time convincing residents of the eastern United States, Scandinavia, and Russia (outside of Sochi, anyway), January’s global average surface temperature balanced out as the fourth warmest in the historical record.
Persistent cold temperatures in the Midwest this winter almost completely frozen over many of the Great Lakes. The Great Lakes Environmental Research Laboratory (GLERL) reported that 88 percent of the Great Lakes were frozen as of mid-February.
Models project that extreme dust events combined with global warming could advance the spring thaw in the mountains of the Upper Colorado River Basin by as many as 6 weeks by 2050. The earlier disappearance of snow could amplify water disputes, extend the fire season, and stress aquatic ecosystems.
Nearly ten percent of U.S. watersheds are living beyond their means when it comes to their water supply. For nearly half the country, water stress is projected to worsen by mid-century because of climate change, according to a recent NOAA-funded analysis.
Why do global climate models behave like they do? The Coupled Model Intercomparison Project (CMIP) panel—a subcommittee of the World Climate Research Programme—designs experiments to evaluate differences among climate models in how they simulate our global climate system and predict future changes.
