So, the bad news is that it is looking increasingly likely that the world will experience a very strong El Nino event this 2014-2015 winter (winter in the N. hemisphere, summer down under).Â There is even talk of a super-El Nino, one to rival 1998's phenomenal event.Â Lots of good information on that here at … Continue reading Bad news, good news, bad news.
Watch the video below and see if you can see where the warming stops: (seen at the wonderful APOD site)
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?
Oh boy, get out the tinfoil. Here's one the conspiracy nuts will howl over. The temperature record that has been showing the lowest anomaly in the recent decades, HadCRU, the dataset managed by the UK's Met Office and the University of East Anglia's Climate Research Unit (CRU), is about to be revised upwards. Met Office … Continue reading Global warming has been underestimated by HadCRU
As fate would have it, no sooner does a disengenous commenter here point out the unusual cold and snow falling on my hometown of Vancouver, Canada than I come accross this amusing comic from Jen Sorenson:
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 NiÃÂ±a cannot erase decades of warming
"I don't think that anyone disagrees with the fact that we actually are in a cold period that started about nine years ago." Um...okay. I guess that's true if your definition of "anyone" excludes every single scientific agency that concerns itself with climate indicators and those of us who actually look at them. A good … Continue reading Inhofe’s alternate reality
A regular here recently offered us this PDF from Willie Soon and Lord Monkton's Science and Public Policy Institute and asks what is wrong with the graph in there. As it happens, Michael Tobis has already taken a look at another very similar construction and identified three deceptions (he kindly called "bugs") in what is … Continue reading What’s wrong with this graph?
I have tried to make it quite clear a few times that regardless of no new record, there is no evidence that the underlying rising trend in global surface temperatures has reversed or stopped. But absent a short term rising trend the inattentive public is very vulnerable to disengenouous denialists claiming warming is over (did … Continue reading So when will we get a new temperature record?
Changes? Well hardly. Apparently the shocking "dog bites man" story of minuscule changes in GISS global anomaly data is making the rounds on denier sites. A poster here embedded the copy/pasted accusation in an off topic thread, it goes thus: Looks like Hansen/GISS is up to their old tricks; Here are the June global temperature … Continue reading GISS record changes
