1. What's amazing to me is that 1998 was actually warmer overall, globally speaking.....
....at least, if UAH temperature measurements are accurate:
(BTW, just so you know, I don't agree with Dr. Spencer's interpretation of the data; he says .2*C as of December. I, however, would peg us at an average temperature rise of about .5*C above 1979 levels, with last month being at around .4*C using that assumption.)
And yet, we didn't get any major heatwaves in '98, but we did in 2011 and last year, too. Truly strange, isn't it? I guess that's why some call it "global weirding".....and, TBH, I think it fits quite well.
