Global Warming and Tornadoes: A Guide for Policymakers Bullet Points:

• The overall number of tornadoes has been declining for the past 45 years.
• The number of strong, F3 or higher tornadoes, has been dramatically declining for the past 45 years.
• Tornadoes, including very strong hurricanes, have always occurred and always will. The existence of modest global warming will not change this.

Short Summary: Tornado activity has been declining during the past 45 years as our planet modestly warms. Strong tornadoes, measuring F3 or higher, have also been declining during the past 45 years. Tornadoes, including severe tornado outbreaks, have always impacted human civilization and likely always will. The fact that tornadoes still occur while global warming occurs does not mean global warming suddenly is the cause of all or even any tornadoes. Some models predict that global warming will make tornadoes less frequent and less severe. Guide for Policymakers – Global Warming and Tornadoes]]>
