Guest essay by Eric Worrall
Associate Professor in Organic Chemistry Maurie Trewhella, of Victoria University (Australia), has just made a stunning claim about global warming, in a letter to the editor.
According to Trewhella;
Ian Dunlop’s warning (Comment, 7/4) is especially sobering. The slowing of atmospheric temperature rise over the past 15 years or so, used by climate change sceptics to debunk the work of the IPCC, is, on the contrary, evidence that the solar energy delivered to the Earth is being absorbed by the oceans. The Arctic and Antarctic ice sheets are acting as giant dampers to contain temperature rise in the oceans. When both of these ice sheets melt away in the next decade or so, the rise in both ocean and atmospheric temperatures will accelerate rapidly and demonstrate that the passing of the tipping points that Dunlop expresses concern about has, indeed, occurred. …
I’m not certain which article by Ian Dunlop Professor Trewhella was responding to, but this article, full of alarmist claims about tipping points and the “dangers” of economic growth, seems fairly typical of Dunlop’s writing.
Professor Trewhella is a person of substance within Australian academia. The press release Ephedrine’s green dream details advanced work being performed by Associate Professor Trewhella and colleagues on yeast, to economically produce important medicines (interestingly their innovation, in this case, involved large quantities of CO2).
To obtain a Chemistry qualification in Australia, you have to study Thermodynamics at an advanced level. Part of being a qualified Chemist in Australia, is knowing how much heat it takes to melt a block of ice.
Does Professor Trewhella really believe that the Antarctic and Arctic ice sheets will “melt away in the next decade”? I hope not. But whatever led to this letter being published, it seems careless to say the least, for the reputation of a man of science, to be associated with such a ridiculous claim.
