Draft Climate Assessment Warns Of Devastating 9°-15°F Warming Over Most Of U.S.

See the link below for more details on how there has already been an increase in extreme weather in different areas.

The rule in Washington, DC is if you want to bury news, release it late on a Friday afternoon. So one can only assume the climate silence crowd prevailed in the release this afternoon of the draft U.S. Climate Assessment.

Perhaps it’s this chart they don’t want folks talking about, from the “Newer Simulations for Projected Temperature” in Chapter 2:


The Assessment, put together by dozens of the country’s top climate experts, makes clear that if we stay anywhere near our current emissions path, we are headed towards a devastating 9°F to 15°F warming over most of the United States (this century), with ever-worsening extreme weather, heat waves, deluges and droughts. As the report notes “generally, wet [areas] get wetter and dry get drier.” Future generations will be wishing for the boring “moist” and “cool” days of 2012 (when they aren’t cursing our names).


U.S. average temperature has increased by about 1.5°F since record keeping began in 1895; more than 80% of this increase has occurred since 1980. The most recent decade was the nation’s warmest on record. U.S. temperatures are expected to continue to rise. Because human-induced warming is superimposed on a naturally varying climate, the temperature rise has not been, and will not be, smooth across the country or over time.


Global sea level has risen by about 8 inches since reliable record keeping began in 1880. It is projected to rise another 1 to 4 feet by 2100.
