We should expect to see plenty more of them month by month through 2100. Thank human activity, which is inducing global climate change.
Extreme weather kills people. Just ask the New Orleans residents who witnessed Hurricane Katrina. It devastates the livelihoods of others, as any farmer in monsoon-prone India will surely tell you. Deaths, famines, poor health, and homelessness will run rampant across the globe if climatologists’ warnings prove true. BUT… This prevalence of harsh weather might be just the kick in the teeth that humanity needs to take aggressive action to stop polluting and climate-altering behavior. Climate deniers can quarrel with climate scientists all they want about the hypotheticals of tree rings, ice cores, and hockey sticks. But there is no denying the tornadoes that have obliterated your neighborhood, the monsoon that has destroyed your farm fields, or the cold spell that is claiming the lives of homeless people all across your city. People will realize the depth of the problem and demand that their leaders finally act.
