Weather Blogs

We currently do not know how tornadoes and severe thunderstorms may be changing due to climate change, nor is there hope that we will be able to do so in the foreseeable future. It does not appear that there has been an increase in U.S. tornadoes stronger than EF-0 in recent decades, but climate change appears to be causing more extreme years--both high and low--of late. We may see an increase in the number of severe thunderstorms over the U.S. by late this century.

The recent catastrophic EF-5 tornado in Oklahoma has prompted me to revisit a blog I posted in April 2011 (ironically that blog was posted just two weeks prior to the deadly tornado outbreak on April 27-28 of that year). This blog updates the lists of all known F-5 and EF-5 tornadoes and other statistics concerning the deadliest tornadoes on record in U.S. and world history.
