A little more on Global Warming (Real or Not)

Here we go again, we all need to pay attention( remember I am no scientist):

Proof of Man-Made Global Warming Grows 'Stronger' ( NOT)...An international team of scientists led by Britain's Met Office.This, so called international group, which seems to be lead by Peter Stott. They read 110 documents of others written since 2007...
Peter Stott , head of climate monitoring at the Met Office Hadley Centre for climate research;" Our climate is changing now and it's very likely human activity is to blame"
I have done some research trying to find out about Peter Stott I found:Peter A. Stott is a climate scientist and Manager of Understanding and Attributing Climate Change at the UK Met Office Hadley Centre for Climate Prediction and Research in Exeter, U.K
I have also found out most of the information about global warming comes from their reading of 110 documents that have been written since 2007. Their predictions of what is likely or not likely comes from computer models. (I would like to know who programs them?) I have no idea who programs these computer with thousands of pages of code but no mention of that is made. By the way, according to one of their own scientist, these computer models are the same computer models they use to predict the weather. Need I say more!!! (OK sorry)
When a question is asked such as; what about the lowering of the temp. "or" hasn't the temp. declined since 1998 ? It is explained away by, looking at a larger length of time or a longer time span. I n any event it seems that anything can be explained away and as I said before I am not a scientist and do not claim to be!
This might not "prove" anything but it is reason to be concerned. ( EXAMPLE: when the thickening of the Arctic ice is explained away by saying, well over the last years it was melting and now it is just refreezing, in the long run it is getting warmer..) There is reason to be careful and watch for yourself. Who are these people do they have reasons they just don't express.
