Is it really plausible that the almost imperceptible changes in climate that we have experienced since the 1930s and 40s are 1000x faster than previous natural climate changes?? We went from the Medieval Warm Period to the Little Ice Age -- a much larger change than the warming of the last century -- in a few hundred years. Google "Younger Dryas" and ask yourself if modern climate change is really 1000x faster than that.
SA, sorry to say, is just makin' $#!+ up again.
Lurkers, his reply is not to provide a link to a source, it is to argue from what he thinks are facts.
My reply to his source is =>
1] The heating we have seen since 1750 is 1.2 deg. C. The cooling to go into the Little Ice Age was about half that.
2] The orbital cycles that cause the shift from ice ages to warmer times and back, etc., are in a cooling trend now and have been for all the last 10K years.
3] Dr. Britt has shown that humans were why the period from 10K ya until 1300 AD had a very flat temp curve was human actions related to growing/spreading farming and cattle herding. Then, the Black Death killed 1/3 to 1/2 of the farmers and herders, which resulted in CO2 and CH4 being pulled out of the air, fairly rapidly by forest re growth. So, the cause of the cooling was related to humans and not natural.
4] So, my source may have left the Little Ice Age out of his thinking, as a case of unnatural climate change.
5] BTW, the LIA lasted until the early 1800s so until the human population had grown a lot from the low point of around 1450 AD and had started burning coal in a big way.
6] In any case, my seat of my pants calculation is that the LIA developed slower than he thinks, and it ended as part of ACC and not "naturally".
