Climate Change May Cause More And Stronger Tornadoes

Climate Change May Cause More And Stronger Tornadoes says new research, report Chris Mooney at Mother Jones, and Joe Romm at Climate Progress. Some evidence indicates that tornadoes are getting stronger.

But records also show that the total number of days with high levels of two key tornado ingredients — wind shear and atmospheric instability (“convective available potential energy, CAPE) — have been increasing over the seasons with climate change, thus upping the chance of tornadoes forming.

Previously global warming was predicted to reduce wind shear and thus tornadoes, but researchers now find that such reductions usually occur on low CAPE days, so the shear effect overall becomes trivial.

Join the swelling numbers of voters TELLING Congress they’ll vote for Clean Energy candidates here. This is an ongoing campaign (the next Congressional election is this year!) so please, spread the word. It’s our way of telling Congress that a strong clean energy voting bloc is out there. This is how YOU can make a difference.
