NRDC released 2011 Extreme Weather Map: Thousands of weather records broken in the US!

NRDC released 2011 Extreme Weather Map: Thousands of weather records broken in the US!

Records for extreme heat and extreme cold were broken in all 50 U.S. states in 2011, according to the Natural Resources Defense Council, an international nonprofit environmental organization. The extremes at time have been disastrous, costing Americans an estimated overall $53 billion. NRDC released a web-based extreme-weather mapping tool showing exactly how areas have been hit, including state-by-state analyses on weather extremes, record breakers, rainfall and snowfall. In 2011, there were at least 2,941 monthly weather records broken by extreme events that struck communities in the US. The frequency and intensity of some extreme events is likely to worsen with climate change.

NRDC reports that 2011 has been a year of unparalleled extremes: 14 disastrous weather events in the US so far this year have resulted in over a billion dollars in property damage – an all-time record breaking number – and their estimated $53 billion price tag doesn’t include health costs. As shown recently, in a first-of-its-kind study published in the journal Health Affairs, when health-related costs of extreme events are calculated, the total tally increases substantially and will likely continue to climb due to climate change. 7 of the 2011 extreme events – a record-high number – are the type expected to worsen due to climate change.

Climate scientists are saying that these events may be part of a troubling trend influenced by climate change. This trend has also been identified by the international reinsurance company MunichRe as they concluded that from 1980 through 2011, the frequency of extreme events in the U.S. is rising.  A Special Report on Extreme Events from the Intergovernmental Panel on Climate Change has already concluded that the effects of climate change will intensify extreme heat, heavy precipitation, and maximum wind speeds of tropical storms.

Climate change is one of the most serious public health threats facing the nation, but few people are aware of how it can affect them. Children, the elderly, and communities living in poverty are among the most vulnerable.
