Climate change does consider the whole earth, but the particular weather effects you experience or I experience will vary.  That is why I used SF, where I lived for a few years.  The weather in the UK and Europe is not driven by the same factors as in the US.  Their experience of worldwide climate change is unlikely to match what we encounter in the US.

Given the ongoing conversation being conducted via scientific papers, as documented at Realclimate, I seriously doubt that the papers being published are all about getting perks.  What is clear is that the available data points are increasing and the ability to sift noise out of the analysis is improving.  Climate change denial is real and it is feeding the failure of political will to engage in a systemic way with the real consequences of climate change now being experienced.
