Extremes

Politics versus science in attributing extreme weather events to manmade global warming.

If you follow me on twitter, you may have noticed that I was scheduled to testify before the House Oversight and Reform Committee on Jun 12 [link].  The subject of the Hearing is Contending with Natural Disasters in the Wake of Climate Change.

Late on Jun 10, I received an email telling me that the Hearing is postponed (as yet unscheduled).  Apparently the Committee finds it more urgent to have a Hearing related to holding the Attorney General and Secretary of Commerce in contempt of Congress [link].  Interesting to ponder that Congressional procedural issues are deemed to be more important than Climate Change.

So I spent all last week working on my testimony (which is why there have been no new blog posts).  I hope the Hearing will eventually happen (Michael Mann is also scheduled to testify).

Hurricanes and climate change constitute a major portion of my testimony.  You may recall my recent series  on Hurricanes & climate change [link].  Specifically with regards to detection and attribution, my bottom line conclusion was:

“In summary, the trend signal in hurricane activity has not yet had time to rise above the background variability of natural processes. Manmade climate change may have caused changes in hurricane activity that are not yet detectable due to the small magnitude of these changes compared to estimated natural variability, or due to observational limitations. But at this point, there is no convincing evidence that manmade global warming has caused a change in hurricane activity.”
