DEBATE about the reality of a two-decade pause in global warming and what it means has made its way from the sceptical fringe to the mainstream.
In a lengthy article this week, The Economist magazine said if climate scientists were credit-rating agencies, then climate sensitivity - the way climate reacts to changes in carbon-dioxide levels - would be on negative watch but not yet downgraded.
Another paper published by leading climate scientist James Hansen, the head of NASA's Goddard Institute for Space Studies, says the lower than expected temperature rise between 2000 and the present could be explained by increased emissions from burning coal.
For Hansen the pause is a fact, but it's good news that probably won't last.
International Panel on Climate Change chairman Rajendra Pachauri recently told The Weekend Australian the hiatus would have to last 30 to 40 years "at least" to break the long-term warming trend.
But the fact that global surface temperatures have not followed the expected global warming pattern is now widely accepted.
Research by Ed Hawkins of University of Reading shows surface temperatures since 2005 are already at the low end of the range projections derived from 20 climate models and if they remain flat, they will fall outside the models' range within a few years.
"The global temperature standstill shows that climate models are diverging from observations," says David Whitehouse of the Global Warming Policy Foundation.
"If we have not passed it already, we are on the threshold of global observations becoming incompatible with the consensus theory of climate change," he says.
A Kildee Comeuppance? Or More Obama Aloofness?
Posted at 6:57 p.m. on March 14
Michigan Democratic Rep. Dan Kildee has been in Congress for a little more than two months, and today the leader of the free world gave him a gentle ribbing about just how new he is to Capitol Hill.
At a closed-door meeting between President Barack Obama and House Democrats, Kildee introduced himself as a freshman, to which Obama said, “Wow, you’re really classing up the place then.”
Kildee then proceeded to ask what one person described as a somewhat “long-winded” question about the importance of creating jobs for his economically distraught district.
“I can tell you’re a freshman because you didn’t pay much attention to the State of the Union,” Obama joked. “I talked about that.”
Amid the resulting laughter, House Democratic Caucus Chairman Xavier Becerra of California then offered to provide Kildee a printout of the speech.
Obama was referring to his $1 billion proposal for 15 manufacturing “innovation centers,” the details of which are still somewhat hazy.
Actually, though, the joke was on Obama: On Wednesday, Kildee had met with the White House legislative affairs team about the innovation centers proposal, so he was quite familiar with it.
And his question was broader, about what types of reforms are necessary to reform decaying urban centers like Flint, Mich., which Kildee represents.
“Dan wasn’t specifically talking about innovation centers in his question,” a spokesman said.
