What used to be considered extreme seems to be an everyday occurrence these days. And that might be the sign of a much larger problem. ?Extreme weather is the new weather reality,? says Mindy Lubber of the Huffington Post.
What does this mean? We can expect more dramatic highs and lows in temperature, storms at unpredicted and unseasonal times, and put simply, weather we cannot possibly be prepared for.
And it will be costly. According to the International Panel on Climate Change (IPCC) 2011 estimates of annual losses have ranged since 1980 from a few billion to above US $200 billion (in 2010 dollars), with the highest value for 2005, due to Hurricane Katrina.
There will also be related problems. Heatwaves one of the least visible forms of severe weather can damage populations and crops due to potential dehydration or hyperthermia, heat cramps, heat expansion and heat stroke. Erosion increases due to dried soils, less land is available for growing crops and bodies of water evaporate causing devastating damage to marine populations ? through decreasing habitats and nutrition present within the waters. Cold snaps also lead to hypothermia, increased caloric intake of farming animals, higher production costs for farmers, lower crop yields due to frost and temperatures that remain unseasonably low.
However, the most significant change will be in the strength of storms ? like the tornadoes that just ripped through Dallas, Texas on December 27, 2015. Hurricane modeling done by the IPCC has demonstrated that hurricanes, simulated under warmer, high CO2 conditions, are more intense than under present-day conditions. Thomas Knutson and Robert E. Tuleya of the National Oceanic and Atmospheric Administration (NOAA) seconded the IPCC?s findings, stating that warming induced by greenhouse gas may lead to increasing occurrence of highly destructive category-5 storms.
While only time will tell just how severe and how devastating our extreme weather events will be, for now, we can consider ourselves warned.
