I wondered if it were possible to have a reasoned and hopefully not heated debate of Global Warming , modeling, observations and arguments for and against. The reason I raise this is because I am a qualified Met and yet I find it difficult to reconcile some of the claims and counter claims that are out there in the media or even in scientific papers and wondered if I am the only one that has doubts about some of the pro global warming predictions and rhetoric and equally some of the anti global warming arguments. I know this is a passionate topic for some, but I want to deal in facts as much as possible rather than emotional unsubstantiated beliefs. Lets start with claims scientists have deliberately adjusted the observations to exaggerate GW. The Karl et al paper in the USA http://www.sciencemag.org/content/348/6242/1469 is controversial to say the least where they removed the Argo float records from the temperature data set to prove that the current 15-18 year "global pause" in temps http://www.metoffice.gov.uk/research/news/recent-pause-in-warming was actually false and that warming has continued.
