Guest post by David Middleton (Featured image borrowed from http://www.hockeyministries.org/rwt-blog-52316) Unfortunately this article is behind a pay wall. While some of the points in the abstract are reasonable, these two seem to be totally unsupported in any literature of which I am aware… An average global temperature increase of 0.6o to 0.9oC from 1900 to…
From climate.gov, making two debunked papers into “cartoon science”, I think Josh could do a better job than this. Mann’s hockey stick is like zombie science, it’s dead, it keeps shuffling about on the streets of science with no purpose except to be reanimated in press releases like this one. Marcott’s paper has a lot…
Kenji got this in his inbox today (donation links redacted): ============================================================= UCS supporter— It’s bad enough that climate deniers get elected to Congress. But it gets much worse: some purveyors of disinformation sit on the House Science Committee. Rep. Lamar Smith, who chairs the committee, wrote a recent Washington Post op-ed replete with misleading information…
Robert Scheaffer reports from the meeting via email: Mann just told TAM (The Amazing Meeting of the Skeptics Society) that there has been no pause in Global Warming, and says claims that there has been are just ‘Cherry Picking’.
People send me stuff. Robert Sheaffer sent part of a blog post titled: The “hockey stick” slaps back by Donald Prothero After reading it, this is what I mailed back:
You’d think academics in the upside down Mann climate proxy world would pay attention, and not repeat the same mistakes of the past. Apparently not. WUWT readers surely recall the Yamal YAD06 (The most influential tree in the world) and the core sample YAD061. Steve McIntyre points out the YAD061 equivalent in Marcott et al,…
Guest post by Nancy Green Tamino claims he has added 3 spikes to the Marcott et al proxy data and the Marcott et al process detects them. Source: http://tamino.files.wordpress.com/2013/04/many_vs_unpert.jpg This, he then proposes, is proof that there are no 20th century spikes in the Holocene. This claim appears to run counter to a prediction I…
Skiphil writes: Andy Revkin of Dot Earth/NY Times blog is inviting questions to be submitted to the authors of Marcott et al. (2013). Since Revkin is one of the only journalists who might have a chance of getting the study authors to be responsive, this is a good opportunity.
Story submitted by WUWT reader Nancy Green There is a message in Marcott that I think many have missed. Marcott tells us almost nothing about how the past compares with today, because of the resolution problem. Marcott recognizes this in their FAQ. The probability function is specific to the resolution. Thus, you cannot infer the…
Just last month, these were the claims: We’re screwed: 11,000 years’ worth of climate data prove it. It’s among the most compelling bits of proof out there that human beings are behind global warming, and as such has become a target on Mann’s back for climate denialists looking to draw a bead on scientists. —…
