Folks... I know I am entering the
lion's den talking in this forum, but Hansen had no basis to say confidently that
last summer's heat wave was caused by global
warming.
If we multiply that over ten years, and figure that the top billion or so of world population is responsible for the
lion's share (say 80 %) of the emissions, could we then conclude that, on average, every member of that top billion (presumably including all on this forum) had contributed the energy equivalent of one Hiroshima bomb (or more) toward atmospheric global
warming over the
last decade?
