Global Warming

I’ve seen the news that the US and Europe have experiencing record heat waves . Well I must add to the list of record high temperatures. I’ve been told that Sao Paulo has been experiencing the highest temperatures on record for the month of July, which is of course the winter down here. The weather has seen highs in the 80’s. But even at night the temperature has stayed in the mid 70’s. Now this may not quite compare to the 100+ temperatures some of you may have been feeling, but for a city that has average winter temperatures in the 50’s this is definitely an abnormal occurrence. Perhaps this is more evidence of global warming.
