My partner Doug sent me this link for an article on global warming. The lead is long, but there's some valid stuff farther down.
The climate is warming. It is almost certain this is caused by emissions of greenhouse gases caused by human activity. Nobody has come up with an alternative explanation that stands up. If the present warming trend continues, nasty things will probably start happening to humans within the next century, possibly the next decade. Something must be done. If nothing is done, then the benign climatic conditions that have sustained human civilisation for 10,000 years are in danger of collapse to be replaced by… well, write your own disaster movie.
