This is a continuation of the dissection of Dan Kuttner’s 11 points regarding the science behind AGW, anthropogenic global warming. Dan posted these on Facebook a few months ago, and he reposted them again this year. He challenges readers to answer his 11 points, and he has agreed to allow me to use his name. He says in a separate communication that this is not a prank and he considers these to be serious matters. Here is Dan’s point number 4:
If global warming is happening, why did they change the name of the crisis to “Climate Change?”
Once again, Dan has assured me he is serious about his 11 points, and this is not some kind of come-on. Respecting that, this is an easy question to answer. And here is mine.
Global warming is still the problem. To be sure, global warming is logically a subset of climate change. If the air and oceans get warmer, the climate is going to change. There is going to be a shift in weather patterns. Predicting what the shift will be is a keener problem than predicting temperatures will rise. So far we have seen temperatures rise in our life times, and we are witness to some of the consequences: melting land and sea ice, rising sea levels, flooding of low-lying coastal regions. Other consequences, less rain here, more rain there, stronger and more frequent storms, some of this can be attributed to rising global temperatures. It is difficult to determine which event is one of the consequences of global warming.
