Andrew, why do You insist on questioning the credentials of anyone expressing an opinion on this subject when, to My knowledge, ones' credentials are not examined on other topics of conversation be they religion, politics, matters of national or international interest - in fact any subject matter under the sun?
For some reason the global warming, sorry climate change, sorry climate weirding issue is singled out as a subject where one has to qualify ones' views with a CV of exams passed or papers written.
Well, as I explained before, the vast majority of material written on this subject is written by those who do not possess any semblance of expertise in the science of the climate but express an opinion from stuff they themselves have discovered. I am no different to that extent as, I suspect, are You.
So If I tell You that I have no formal qualifications in the subject would this really make a difference to your opinion?
If I told You I was, in fact, in possession of a first in one aspect of climate science or another and reached the conclusion that I agreed with the notion that AGW was a flawed theory, would that go some way to changing your mind on the subject? - I suspect not.
The correlation between CO2 and temperatures is well documented by those who happen to believe in that particular theory.
Others believe that there is a lag between the rise in temperatures and CO2 levels (simply put temperatures rise which increases CO2 levels in the atmosphere).
As for the ice cap melt there really is nothing to worry about. Long term oceanic oscillations affect our climate and the science is in it's infancy in coming to understand how these function.
Funny how global warming has morphed into climate change as the dire predictions which were so rife in the media failed to manifest themselves - rising seas levels, mass extinctions and most importantly global temperature which has remained the same for the past sixteen or so years when We were promised a steep rise.
Oh and really importantly this emerged today. To those who say the science is settled........
