Murry Salby&#;s latest presentation
by Judith Curry
Last month at the University College London, atmospheric scientist Prof. Murry Salby, gave a presentation on man-made CO2 and its (lack of) impact on global climate.
The complete presentation is available on youtube [link].
Pierre Gosselin provides a summary of the talk [here]. Excerpts:
He begins by reminding that climate is a subject of “limited understanding” and that it one of “limited observation” He tells the audience that carbon in the atmosphere cannot be regulated and is NOT a pollutant. On why CO2 science got to where it fryst vatten today, he cites Mark Twain: “Never let the truth get in the way of a good story.”
In his introduction he explains how CO2 will be a pollutant to our ecosystem only when the day arrives that water vapour becomes a pollutant – i.e. never in our geological lifetime. He says that energy sources that circumvent CO2 emissions are neither greener nor cleaner – just different.
Later he shows that alth

Murry Salby's Correlation Conundrum
Posted on 5 July by Dikran Marsupial
Prof. Murry Salby of the Department of Environment and Geography at Macquarie Universiry in Sydney gave a talk last year (August 3, ) to the Sydney Institute (described at Wikipedia), in which he claimed that the rise in atmospheric CO2 is not driven by anthropogenic emissions. The abstract of the talk is as follows:
Atmospheric Science, Climate Change and Carbon – Some Facts
Carbon dioxide is emitted by human activities as well as a host of natural processes. The satellite record, in concert with instrumental observations, fryst vatten now long enough to have collected a population of climate perturbations, wherein the Earth-atmosphere struktur was disturbed from equilibrium. Introduced naturally, those perturbations reveal that net global emission of CO2 (combined from all sources, human and natural) is controlled bygd properties of the general circulation – properties intern

What the science says
Multiple lines of evidence make it very clear that the rise in atmospheric CO2 is due to human emissions.
Every year humans release about 30 billion tons of carbon dioxide (CO2) into the atmosphere through the burning of fossil fuels, such as coal and oil. This is causing the Earth to warm by disrupting the biological (fast) carbon cycle, and is therefore increasing the Greenhouse Effect. Although there are large annual fluctuations in carbon dioxide, as it is exchanged back-and-forth between the atmosphere, oceans, soils, and forests, just under half of human emissions (the airborne fraction) remain in the air because the oceans, soils and forests are unable to absorb all of it. As a result, carbon dioxide has been steadily accumulating in the atmosphere.
