Still warmin’ after all these years (Prat watch #5.6)

1967withlines

Courtesy of Texas state climatologist John Nielsen-Gammon, a very nice graphical demonstration of why “warming” hasn’t stopped in the last decade (or two). Nielsen-Gammon took the GISS global temperature series, classified years as El Niño dominated, neutral, or La Niña, excluded the influence of the Pinatubo-cooled years in the early 90s, and then calculated the trends for each set. The graph really says it all, but his blog post provides all the analysis. The next El Niño looks as though it’s going to be interesting…

Cuckoo cocoon (Prat Watch #5.5)

Something stirred inside the carefully cultivated cocoon of ignorance at Richard Treadgold’s Climate “Conversation” blog, but I don’t think it was the butterfly of understanding preparing to inflate its wings. Something much more subterranean, I suspect. Needled by my post about said cocoon (namely, Treadgold’s insistence that “global warming has not happened for about 15 years, unless you take a micrometer to the thermometer“), RT issues a bold challenge: Well, where’s your evidence, Renowden?

He heads his post with a graph lifted from JunkScience (that well known purveyor of same), showing the HadCRUT3 monthly temperature series from 1978 to date. Amusingly, Treadgold makes an error before he even begins the meat of his diatribe. The caption he provides to the graph includes this:

The graph that proves no significant warming for about 15 years – since about 1996. Measured by satellite, not the unreliable hand of man.

The HadCRUT3 global series is most assuredly not a satellite generated temperature record. But we’ll let that pass, shall we, and take a quick canter through an answer to his challenge. I shall ignore Mark Twain’s advice just this once, in the hope that some light may shine in to the dark corners of his misunderstanding.

Rough Winds: Extreme Weather and Climate Change

James Powell has produced a Kindle eBook, Rough Winds: Extreme Weather and Climate Change, which in brief compass links climate change to the extreme weather events increasing across the globe.  As a Kindle Single it has the advantage of being right up to date with what has been happening in the US, including the visit of Hurricane Irene. You don’t need a Kindle to read it – apps are available for other devices and I read it on my PC. It cost 99 cents!

Powell is the author of the recent book The Inquisition of Climate Science which I reviewed here. He’s a former geology professor, college president and museum director who also served as a member of the US National Science Board for twelve years. In Rough Winds he writes for the general reader. He points out that scientists have been thinking about global warming for nearly two centuries. It is one of the oldest concepts in science, recognised first in the 1820s and then refined in the 1860s and 1890s and steadily throughout the second half of the 20th century. Moreover it’s uncomplicated and incontrovertible. There’s no escape from the elemental fact that the extra CO2 we are putting into the atmosphere will cause future temperatures to be higher than they would otherwise have been. And the warmer the earth, the more extreme will be the weather. Continue reading “Rough Winds: Extreme Weather and Climate Change”

This Is Not Cool

Return of the Climate Clueless™: there’s none so blind…

Sir Peter Gluckman, scientific adviser to NZ prime minister John Key, recently published a discussion paper entitled Towards better use of evidence in policy formation (pdf). It’s an interesting read for anyone who has ever noted the sometimes large discrepancy between political dogma and policy outcomes. Sciblogger Peter Griffin went so far as to describe it as “possibly one of the most important [papers] he has released thus far”.

Over in the land of the Climate Clueless™ however, Richard “Climate Conversation” Treadgold has taken Gluckman’s paper as a cue to demand evidence of climate change. Treadgold appears to have forgotten that one of Sir Peter’s first acts following his appointment was to review the evidence and issue a statement on the subject, and is perhaps still smarting from Gluckman’s comments on climate denial last year. He therefore issues this stern challenge:

I would remind Sir Peter that evidence is required to establish the following key factors in the global warming debate — evidence that has not surfaced so far. We have been looking for evidence to show:

  1. The existence of a current unprecedented global warming trend.
  2. That the greenhouse effect is powerful enough to endanger the environment.
  3. A causal link between human activities and dangerously high global temperatures.
  4. That climate models have a high level of skill in predicting the climate.
  5. A causal link between atmospheric levels of carbon dioxide and global temperatures.
  6. A causal link between global warming and the gentle rise in sea level.

Time to play some whack-a-mole…
