The BBC is relentless and continues to push the AGW agenda, in fact pushing it harder now that global warming has ‘stalled’ (and the BBC’s impartiality review of their coverage of climate is over)….can’t have anyone getting complacent and thinking it’s nothing to worry about children!
Once again they roll out the old trick of inviting someone on to be interviewed about their work knowing full well that the real intention is to get around to a particular subject.
‘Today’ frequently invited on guests, musicians, artists and writers, to talk about their work but it was rare to never that somehow the interview didn’t end up with a denunciation of George Bush and the war in Iraq.
In a similar vein the BBC frequently invite scientists onto the ‘Life Scientific’ to talk about their speciality only to end up with strongly worded support for the AGW lobby.
The latest programme was no different when the BBC invited scientist Mike Benton onto the ‘Life Scientific’ to talk about dinosaurs and all that but the whole programme seemed designed around that one theme…climate change.
Presenter Jim Al Khalili didn’t waste any time and made the introductions saying:
It’s a sobering thought that just a few degrees rise in global temperature led to mass extinction that wiped out nearly all life on the planet.
He later repeated this and ensured we got the message and then connected it to climate change today asking if it is a likely scenario that could be repeated if we don’t change our ways:
It sounds terrifying that just an initial few degrees rise in temperature can trigger further global changes that can lead to the wiping out of all life…is this something that we should be worried about with the current changes in our climate?
Did you get that? Just a few degrees in temperature rise and all life will be extinguished.
We’re on a knife edge and the slightest change in the level of CO2 and a resulting tiny rise in temperature will have a snowball effect (?) that could drive us over that edge..to extinction.
Something must be done!
Mike Benton, though a ‘dinosaur scientist’, seems more concerned with climate these days and seems to have reinvented himself as a climate change advocate:
Benton, M.J. Presidential Address 2007: The end-Permian mass extinction events on land in Russia. Proceedings of the Geologists’ Association Volume 119, Issue 2, 2008, Pages 119-136
Conclusion: If the runaway greenhouse model is correct and explains perhaps the biggest crisis on Earth in the last 500 Ma, it is a model worth exploring further. It appears to represent a breakdown in global environmental mechanisms, where normal systems that would equilibrate atmospheric gases and temperatures took hundreds of thousands of years to come into play. Models for ancient extinction events affect the current debate about global warming and its possible medium-term consequences. Some scientists and politicians look to the sky for approaching asteroids that will wipe out humanity. Perhaps we should also consider how much global warming can be sustained and at what level the runaway greenhouse comes into play.
