Genuine Risk,
If you get a chance, you might want to pick up James Lovelock's newly released book. It's a best seller in Britain and was released in the US last month.
Lovelock is the scientist that discovered the causes for problems in the ozone layer, provided data to Rachel Carson, and has views that are disrespected...until they come to be reality.
His take is that discussing "politics" doesn't matter much. Time is short, and irreversible.
