Just after I published the last post, I read this [quote](http://thecaucus.blogs.nytimes.com/2011/04/28/obama-announces-changes-to-national-security-team/?hp) from President Obama, made at the opening of his press conference to announce his new national security team.

As I wrote just a few minutes ago, he’s not quite right. Recent [scientific findings](http://voices.washingtonpost.com/capitalweathergang/2011/02/sifting_through_evidence_on_cl.html) do show evidence of a connection between human-activities-based contributions to global warming and severe weather patterns. If so, we may be able to reduce the frequency and severity of tornadoes and other extreme events by modifying our behavior.
