Keeping his cool: the sceptical environmentalist

Similarly, Europe’s deadly heat waves in 2003 lead Gore to conclude that climate change will mean more fatalities. But global warming would mean fewer deaths caused by cold temperatures, which in most of the developed world vastly outweigh deaths caused by heat. In the UK alone, it is estimated that the temperature increase would cause 2,000 extra heat deaths by 2050, but result in 20,000 fewer cold deaths.
Financial losses from weather events have increased dramatically over the past 45 years, which Gore attributes to global warming. But all or almost all of this increase comes from more people with more possessions living closer to harm’s way. If all hurricanes had hit the US with today’s demographics, the biggest damage would have been caused not by Katrina, but by a hurricane in 1926. Allowing for changes in the number of people and their wealth, flood losses have actually decreased slightly.
The movie invites viewers to conclude that global warming caused Hurricane Katrina, with Gore claiming that the warm Caribbean waters made the storm stronger. But when Katrina made landfall, it was not a catastrophic Category 5 hurricane; it was a milder Category 3. In fact, there is no scientific consensus that global warming makes hurricanes more destructive, as he claims. The author that Gore himself relies on says that it would be “absurd to attribute the Katrina disaster to global warming.”
At the climax of his movie, Gore argues that future generations will chastise us for not having committed ourselves to the Kyoto Protocol. More likely, they will wonder why, in a world overflowing with inconvenient truths, Gore focused on the one where we could achieve the least good for the highest cost.
MSN: So, are we to assume the global Live Earth events of July 2007 left you cold?
BL: It's honourable that the Live Earth organisers are so concerned about the far-off future, but you have to wonder why there is so little concern about the much-worse present. I don't want to stop anyone from caring about climate change, only to encourage a sense of perspective. There is a massive amount of good that we can do through practical, affordable approaches like HIV/AIDS education, malaria prevention, and the provision of micro-nutrients or clean water. This is the message I would like to ring out: we should focus on the best ideas first. At the Live Earth events, unfortunately, that is not what we heard.
