Hum,
i also think that most ppl don’t realise that a warmer planet also means more cloud cover, that `hides` the true extent of the effects of any pollution.
" This means that the climate may in fact be more sensitive to the greenhouse effect than thought. " - from article.
The danger here is that while we cannot point to any one climatic event and say that was due to global warming - a threshold maybe reached that accelerates the frequency of these events....
