The skillful predictions of climate science

Surely the first Met Office graph is a mistake? It does not look remotely frightening enough 😀

Thanks Paul. Excellent post.

The IPCC Report

Smith et al (2007): 0.3°C in 10 years

In 2007, a team of climate scientists from the UK Met Office led by Doug Smith wrote a paper “Improved Surface Temperature Prediction for the Coming Decade from a Global Climate Model”, published in the journal Science.  Although published in 2007, the paper made predictions for the decade 2004-2014. (Presumably the work was started around 2004 and it took some time for the paper to be published). The paper made claims about the “skill” of the model, for example “Having established the predictive skill of DePreSys…

The Smith et al paper made the following specific predictions:

  • There would be 0.3°C warming over the decade 2004-2014
  • At least half of the years after 2009 would be warmer than the record year of 1998.

Note that at that time, 2007, the warmest year was thought to be 1998; subsequent adjustments to…

Contrasting Good and Bad Science: Disease, Climate Change and the Case of the Golden Toad

I have often thought (and said) the CO2 meme takes valuable resources, time and effort away from real environmental issues. A very good read.

Watts Up With That?

Guest essay by Jim Steele, Director Emeritus, Sierra Nevada Field Campus San Francisco State University

clip_image002To insure the public does not become complacent as the 16-year hiatus in rising global temperatures continues, the media is spammed with untested models claiming rising CO2 is and will spread death and destruction via food shortages and disease.

As MIT’s world-renowned oceanographer Carl Wunsch warned “Convenient assumptions should not be turned prematurely into “facts,” nor uncertainties and ambiguities suppressed…Anyone can write a model: the challenge is to demonstrate its accuracy and precision…Otherwise, the scientific debate is controlled by the most articulate, colorful, or adamant players. (emphasis added)”1As presented here before, the extinction of the Golden Toad illustrates the great abyss that separates the rigor of good medical science from the opportunistic models trumpeted by a few articulate and adamant climate scientists. The lack of substance in climate propaganda…
