Do greenhouse gases warm the planet by 33°C? Jinan Cao checks the numbers.

Jinan Cao has been dissecting the nature of the greenhouse effect and a key calculation that I normally just accept without questioning. This will set a few pigeons loose, but it will be interesting to see where they land. Continue reading

Imaginative feature on Paul Nurse: A Redoubt of Learning Holds Firm

Bizarrely Sir Paul conflates scientific skepticism with superstition and taints CAGW skeptics with anti vaxxers and fear of modernity. CAGW hysteria is doing more damage to science and society that even religious zealotry has done and that is desperately dangerous. See this item for a direct quote from the IPCC’s Working Group I disclaiming an ability to predict future climate states and the linked examination of probable climate sensitivity to enhanced greenhouse effect, drawn directly from Earth’s natural greenhouse effect and too trivial to worry about or even detect amid the noise of natural variation.

The boy who cried ‘Warming’

This is apparently a feature length video. It has ben strongly recommended to me although I have not yet had an opportunity to view it.

Another confused effort: Proving the greenhouse gas effect does not exist

This time from Berthold Klein. These misguided efforts are a real worry. Just because GHE is poor nomenclature does not mean earth acts like a physical greenhouse (it doesn’t) but the lower atmosphere is most assuredly warmed by compression, conduction, evaporation and transpiration and through absorption of infrared radiation. All manner of seriously stupid claims are made with reference to the infrared absorption and radiation part. Continue reading

Does the IPCC really believe anyone can predict the future?

In sum, a strategy must recognise what is possible. In climate research and modelling, we should recognise that we are dealing with a coupled non-linear chaotic system, and therefore that the long-term prediction of future climate states is not possible.”

So states the IPCC’s Working Group I: The Scientific Basis, Third Assessment Report (TAR), Chapter 14 (final para., 14.2.2.2), p774.

It is also about the only unequivocally true statement made by the IPCC in the Third Millennium. Continue reading

Roger Pielke Sr.: Skeptical Science Survey By John Cook On “Climate Related Research”

My view of this survey is that it is much too limiting in the questions they are asking regarding the findings in the peer reviewed literature. It appears they are writing their questions to reinforce a preconceived perspective, rather than complete an actual survey of the diversity of viewpoints in climate system science and the role of humans in its alteration. Continue reading

William Gray: In climate change, we are not to blame

An important process with regards to weather/climate change is the prevalence of naturally occurring multi-decadal periods of up-and-down swings in temperature, precipitation and other climate elements. The usual period of these variations is about 50 to 60 years or roughly 25 to 35 years between low to high or high to low periods. Continue reading

“Never have so many scientists forecast so far into the future such fearful weather with so little risk of consequence for being wrong.” – I just made that up. Continue reading

Duncan Steel: Climate Change And The Shape Of The Earth

This is what scientists are supposed to do, find inconsistencies, point them out, and put them right. And so I gave this a little thought. Continue reading

Predictions by climate models are flawed, says invited speaker at Sandia

Massachusetts Institute of Technology professor Richard Lindzen, a global warming skeptic, told about 70 Sandia researchers in June that too much is being made of climate change by researchers seeking government funding. He said their data and their methods did not support their claims. Continue reading

Comments On The Cato Report “ADDENDUM: Global Climate Change Impacts In The United States” By Michaels Et Al 2012

I have been alerted to an informative, much-needed detailed 2012 Cato Institute asssessment of the 2009 US government report “Global Climate Change Impacts in the United States. See also Judy Curry’s excellent post on the Cato report at Cato’s Impact Assessment  Continue reading

Hockey Schtick: Paper finds climate is ‘highly sensitive to extremely weak’ changes in solar activity

A paper published in Science by the esteemed geologist Dr. Gerard Bond and colleagues finds that “Earth’s climate system is highly sensitive to extremely weak perturbations in the Sun’s energy output, not just on the decadal scales that have been investigated previously, but also on the centennial to millennial time scales.” Continue reading

Rise in temperatures and CO2 follow each other closely in climate change

Despite the reluctance of their admission they do state specifically that “Our analyses of ice cores from the ice sheet in Antarctica shows that the concentration of CO2 in the atmosphere follows the rise in Antarctic temperatures very closely and is staggered by a few hundred years at most” em added Continue reading
