I lifted the title of this post directly from Roger Pielke Jr.s blog. I thought it was a good statement and his short post is even better. The sub-title … Correlation should make you curious not convinced. Again, lifted from a comment at his post.
What happens in the weather this week or next tells us absolutely nothing about the role of humans in influencing the climate system. It is unjustifiable to claim that a cold snap or heavy snow disproves or even casts doubts predictions of long-term climate change. It is equally unjustifiable to say that a cold snap or heavy snow in any way offers empirical support for predictions of long-term climate change. This goes for all weather events. …
Knowledge of climate requires long-term records — on the time scale of a decade and longer.
The first comment at VC has a suggestion for the following sentence…
Knowledge of climate requires accurate long-term records — on the time scale of a decade and several centuries or longer.
Ahh, another good comment at VC.
If the other side can win people over with a picture of a polar bear on an ice floe or saying Katrina was caused by CO2 emissions, then our side can win them back by pointing out record snowfalls in DC. That’s only fair. Skeptics would be perfectly happy to disregard all evidence other than thermometer readings if the AGW crowd would do the same.
