Yes there are almost certainly some casualties already to climate change but almost certainly considerably less than either of these numbers; there have always been casualties due to ‘Heat &amp; Cold Illnesses’ (35000) but are all these attributable to climate change? Probably not. There were extreme weather events even before climate change. Even if there are such deaths this does not amount to meaning the developed world should fund adaptation; just like not every outbreak of violence in Africa should be considered the responsibility of the developed world not every natural disaster is.
