Roger Pielke Jr. Writes :
the IPCC should be congratulated for delivering a message that cannot have been comfortable to deliver. The IPCC has accurately reflected the scientific literature on the state of attribution with respect to extreme events — it is not there yet, not even close, for events such as floods, hurricanes, tornadoes, bushfires and on other topics there remain enormous uncertainties. That is just the way that it is, so that is indeed what the IPCC should have reported.
I’m not so generous. Why is the IPCC looking for attribution? First they should look to see if there is a trend, and only then look for a cause. The fact they are looking for a specific result indicates an agenda.
Landfalling hurricanes and severe tornadoes are on the decline, and the IPCC should be reporting it, not hiding it.
