The future is now?

There is much talk this week of the runaway effects of climate change or global warming. James Lovelock has been warning of this for some time and speaks about this in his interview with Hardtalk (BBC News24, July, 2004) http://news.bbc.co.uk/2/hi/programmes/hardtalk/3937609.stm . The Geological Society has also got its forecast out for the human race, (if you've got children, look away now.....); http://www.geolsoc.org.uk/template.cfm?name=Global_Warming_Essay .

None of the above makes for easy reading (or listening). In fact, it all seems extremely surreal. These people are however eminent scientists in their field, not nutters! ....Or are they?
