Extreme Weather in 2011

For the second year in a row, unprecedented numbers of extreme weather events have occurred across the globe. However, more of 2011’s impacts occurred in the United States. From the drought in Texas to the floods in the Midwest and Northeast, this past year underscored the huge economic costs associated with extreme weather.  While specific weather events are not solely caused by climate change, the risks of droughts, floods, extreme precipitation events, and heat waves are already climbing as a result of climate change. This year reminded us of our vulnerability to those events.

That’s One Small Step for the IPCC; One Giant Leap for Understanding Our Climate Risk

The Intergovernmental Panel on Climate Change (IPCC) released a “special report” (that’s what they call topical reports they publish in between their better known comprehensive assessments) today that is worth a close look for anyone who wants to start getting ready for a future with weirder and often harsher weather.

About a year ago I published an opinion editorial taking the Intergovernmental Panel on Climate Change (IPCC) to task for neglecting risk-based information to help decision makers cope with inevitable uncertainties about the future impacts of climate change:

Since uncertainty is endemic to the future, when the second IPCC assessment concluded in 1995 that ‘The balance of evidence suggests a discernable human influence on the global climate’, the IPCC should have reconvened around the risk implications of this probable human influence. Instead, it redoubled its effort to reduce physical science uncertainties [which will not be resolved before action is required].

Global Warming Contributing to Texas Drought

Recently, President Obama quipped about GOP presidential candidate and Texas governor Rick Perry: “You’ve got a governor whose state is on fire denying climate change.” While this type of election jousting risks further politicizing an issue that should be totally non-partisan, it raises a legitimate question: Is climate change increasing the risk of drought and wildfires in Texas?

Flood Damages Stacking Up in Northeast

With the Northeast still reeling from the impacts of Hurricane Irene, the possibility of even more flooding was almost too much to comprehend. But last week the remnants of Tropical Storm Lee stalled and sent plumes of precipitation toward the Northeast, creating a replay of the floods a few weeks earlier. This time the area along the Susquehanna River in Pennsylvania and New York was in the bulls-eye. Since the ground was still saturated from Irene, this new round of flooding was worse, surpassing the previous record event set in 1972 when Hurricane Agnes dropped a torrential downpour on the area.

Irene’s Impacts Hit Home

During the last weekend of August, the Eastern U.S. braced for a walloping. Hurricane Irene spiraled up the Atlantic coast, ripping trees out of the ground in North Carolina and drenching much of the rest of the coast. When I heard that Irene was making her way up toward my hometown of Ridgewood, NJ, I had flashbacks to Hurricane Floyd, a devastating storm in 1999 that brought us much destruction and devastation.
