I find it fascinating that the
IPCC's much-awaited epic tome on climate change released today was mainly held up due to having to reach a consensus about semantics.
All this science, yet the salient issue was whether to say that global warming is
'very likely' (90% probability) caused by man, or perhaps use the more frightening term
'virtually certain' (99%).
Yet they feel they "have this nailed", according to top U.S. climate scientist Jerry Mahlman, who originated the percentage system.
One of the study's many co-authors,
Andrew Weaver of the University of Victoria said that the report was "based on science that is rock-solid, peer-reviewed and consensus."
"It's very conservative. Scientists by their nature are skeptics.''
What's that?
You can be a "conservative skeptic" and still have environmental credibility? Someone should tell those jokers in Question Period.
In any case, to borrow scientific language, I agree that it is 'very likely' that human beings have something to do with climate change - The question is how much and what can we realistically do about it? Ban human beings from the planet? Apparently the damage is already done to the extent that all we can do is hope to slow down the inevitable (
CTV):
"This is just not something you can stop. We're just going to have to live with it," co-author Kevin Trenberth, director of climate analysis for the National Center for Atmospheric Research in Boulder, Colo., told The Associated Press in an interview. "We're creating a different planet. If you were to come up back in 100 years time, we'll have a different climate."
Trenberth said scientists do worry that world leaders will take the message in the wrong way and throw up their hands. Instead, the scientists urged leaders to reduce emissions and also adapt to a warmer world with wilder weather.
Well, that much seems reasonable anyway.
Rex Murphy had an interesting commentary on the
National last night (now available
here), where he made some excellent points. One of the main ones was to question how much each individual is willing to give up in terms of living a less affluent lifestyle, rather than simply donning a green scarf.
What would
you give up? Your job at your pollution-spewing factory? Your second or third car? Your vacations? Your high-tech toys that have environmentally-unfriendly components that can't be disposed of in landfills?
The other concern, as Rex Murphy pointed out in
last Saturday's Globe, is do we trust politicians to handle the problem effectively?
If we believe global warming is as big a problem as the world's experts are telling us, we also have to believe the world's politicians are capable of fixing it. That's a leap of faith the record doesn't support.
Every tiny corner of this planet, big or small, is a record of some politician's failure. Check your street: How long have the potholes been there? How's traffic in your downtown? The VancouverEastside — how long has that been a blight? Darfur? Oil for Food? Now, we want to believe the politicians are going to fix the weather of the whole world.
The world wants its politicians to “do something” about global warming.
Most likely, alas, they will.
I suppose
my biggest concern right now is that this report, along with current polls will cause some kind of
bumbling, disingenuous knee-jerk reaction in Parliament as politicians fall all over themselves trying to be
'seen' to be be green.
But at the ballot box, that's all that counts.
