Yes, this winter in the northeast US was slightly colder and slightly wetter than the norm. We didn't have a total thaw in late January like we usually have, but we are getting more early and late snowfall as well. Its March and we are still getting temps below zero F at night, barely hitting the 20-30 deg F range during the day. Of course local conditions are not 'representative' of the system.
The stats I find interesting is that those that claim global warming say that it is triggering more very violent storms, hurricanes, etc., yet when you look at the hurricane data, something like 75% of the most dangerous, high power, and damagine hurricanse on record for the 20th century occured before the middle of the century. This is a significant and incontrovetible indication that the predictions of the global warming claimers are off by a wide margin.
To me, global warming is a non issue for extropians. By the time it is a problem to us, we will be able to fix it with a quick nano-tech recipe. I also see it as having good aspects:
