climate change: More Lightning to Come with Warmer Climate


 

More Lightning to Come with Warmer Climate

As global temperatures rise, so too will lightning strikes, says one team of climate researchers. According to the team’s projections, every 1°C rise in global temperatures will lead to a 12 percent increase in lightning strikes, so that by 2100 there will be three lightning strikes for every two in 2000. Increased lightning strikes have both positive and negative implications for the environment. Lightning strikes currently ignite half of all wildfires in the US, so it stands to reason that wildfires may increase along with lightning. However, on a more positive note, lightning also produces nitrogen oxides, which indirectly regulate greenhouse gases like ozone and methane. More… Discuss

 

WARMING TEMPERATURES COULD CAUSE MORE KATRINAS


Warming Temperatures Could Cause More Katrinas

One hopes that storms such as 2005’s Hurricane Katrina, which devastated the Gulf Coast, and last year’s Superstorm Sandy, which caused fatalities in nine countries and upwards of $75 billion in damage, would be few and far between. Unfortunately, researchers are projecting that the number of Atlantic hurricanes of this magnitude will dramatically rise over the coming years. These storms are extremely temperature sensitive, and given the warming that took place over the course of the 20th century, researchers expect the number of Katrina-strength storms to double in the 21st. If global temperatures continue to rise, this number could get even higher. More… Discuss
