Tell us Martin, are weather and climate the same thing.Here is my answer: Weather and climate are not the same thing in the case of reports of unusually cold weather, where we go into finger-wagging mode and give people who take note of it lectures about how just because we are freezing our booties off and considering the virtues of muktuk and Caribou jerky that this does not mean anything significant about the temperature of the planet; but weather and climate are the same thing when a newspaper reports that someone in Greenland notices a glacier starting to drip or someone in Alaska hasn't seen a polar bear in over a week, in which case we clam up and contract a bad case of amnesia about the relation of weather and climate.
I wonder how many blogs this commenter has posted on making this same point in the case of the countless reports that have reported some warm weather event somewhere that is the direct result of global warming.
In other words, no particular cold weather event can be taken as evidence against global warming, and all particular warm weather events can be taken as evidence for it.
Then there is Josh Rosenau of the National Center for Science Education, who responded by quoting Roger Peilke:
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 [on] 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.I wonder how many posts Josh has made cautioning those who equate weather and climate when discussing warm weather events.
