Saw an interesting prog on the TV awhile back about global warming and dimming
keeping each other in balance.....

IIRC, it suggested that the extra sunlight coming through the holes in
the ozone layer, was being diffused by the pollution layer beneath.
As global warming and levels of skin cancer are still rising, it would
seem that we need even more pollution to protect us! :-(
