Global Warming is becoming more & more extreme.

Hot, Hot, Hot!

Consistent with widespread media reports of extreme heat and adverse impacts in various places, the latest results from ERA-Interim indicate that the average temperature over land areas of the extratropical northern hemisphere reached a new high in July 2010. May and June 2010 were also unusually warm.

Dr. Jeff Masters of the Weather Underground has a word or two about heavy snowfall in a warming world:

The U.S. Global Change Research Program (USGCRP) ... has put out some excellent peer-reviewed science on climate change that, in my view, is as authoritative as the U.N.-sponsored Intergovernmental Panel on Climate Change (IPCC) reports. In 2009, the USGCRP put out its excellent U.S. Climate Impacts Report, summarizing the observed and forecast impacts of climate change on the U.S. The report's main conclusion about cold season storms was "Cold-season storm tracks are shifting northward and the strongest storms are likely to become stronger and more frequent".

ArkStorms, coming soon to a theater near you.

Actually, the science is not that Hollywood.

The most powerful storm in recorded history for the region swept through the Southwestern United States last week, “bringing deadly flooding, tornadoes, hail, hurricane force winds, and blizzard conditions.”

"We expect to get powerful winter storms affecting the Southwest U.S. during strong El Niño events, but yesterday’s storm was truly epic in its size and intensity. The storm set all-time low pressure records over roughly 10 – 15% of the U.S.–over southern Oregon, and most of California, Nevada, Arizona, and Utah." ~Jeff Masters

However, this record storm is only a preview of what is to come in a warmer world. Global Boiling: Preparing For Frankenstorms

The USGS Multi Hazards Demonstration Project (MHDP) is preparing a new emergency-preparedness scenario, called ARkStorm, to address massive U.S. West Coast storms analogous to those that devastated California in 1861–62. Storms of this magnitude are projected to become more frequent and intense as a result of climate change. ARKSTORM: WEST COAST STORM SCENARIO
