What did temperatures do as the last glacial minimum ended 120K years ago?

A commenter on the most recent edition of het's AWOGWN asks an interesting set of questions: How would temperature data have been seen during the last 10,000 years prior to the peak of each of the previous Milankovich cycles? What caused the temperature to reverse course in those cycles and why would we not expect … Continue reading What did temperatures do as the last glacial minimum ended 120K years ago?

Global warming has been underestimated by HadCRU

Oh boy, get out the tinfoil. Here's one the conspiracy nuts will howl over.

La Niña cannot erase decades of warming

A great and substantive post up at Skeptical Science on La Nina and what we should expect (and not expect) in terms of its impact on global temperatures. Read it all! (image borrowed from Skeptical Science) La Ninas typically redistribute the global heat budget in such a way as average surface temperatures are depressed from … Continue reading La Niña cannot erase decades of warming
