On Mon 16th May at the annual Imperial College Lighthill Lecture* – this year by Professor Sir Brian Hoskins on ‘Predicting Weather and Climate’ – WeatherAction astrophysicist Piers Corbyn, First class Physics graduate from Imperial College, challenged Sir Brian to produce observational evidence of CO2 driving changes in Climate * http://www.imperial.ac.uk/fluids-cdt/about/lighthill-lectures/
In the discussion section of the event Piers thanked Sir Brian for his superb presentation on meteorology concepts and processes and said that however he had difficulty with his comments on Carbon dioxide and climate. Piers said
“The problem you have is that there is no observational evidence that world temperatures follow CO2 levels but the relationship is the other way. The trace gas CO2 follows temperatures with delays of some centuries because the relative partition between CO2 in the air and in the sea – which holds 50 times more CO2 than the atmosphere – is controlled by Sea (surface) temperatures (under Henry’s Law) and I challenge you to provide evidence of your claims”
Sir Brian said there was evidence in the UN IPCC reports.
Piers said “No, there is no evidence in those reports only opinion. We must rely on evidence not opinion”. Sir Brian said he agreed evidence not opinion was required. Piers said Yes we need to see a graph of observational evidence please send evidence to piers@WeatherAction.com ”
Afterwards Piers gave his business card with email to Sir Brian.
Further Comment from Piers: We will keep WeatherAction site updated on any responses. Sir Brian’s CO2 and Climate claims did not follow in any way from the main part of his presentation on world weather description parameters and meteorological concepts and processes.
His claims that Man’s CO2 lasts thousands of years and that this is causing Ocean acidification are factually false (but we didnt have time to discuss these). For a start IF Man’s CO2 lasts thousands of years in the atmosphere it cannot also be in the sea causing so-called ‘acidification’. The fact is that because the sea holds 50 times more CO2 than the all even if all atmpsheric CO2 went into the sea – let alone man’s 4% contribution to it – which anyway it cannot because of Henry’s partition Law, it could potentially have only a trivial effect which is further suppressed by the ‘buffer solution’ nature of the sea.
There is a dynamic balance between CO2 in the sea and air and on average half any atmosperic@ CO2 will enter the sea in a few years and CO2 is similarly releaased from the sea at close to the same rate.
