When you read the following, keep in mind the bias of The Australian, and the undeniable facts embedded in its reporting.
From the Australian:
DEBATE about the reality of a two-decade pause in global
warming and what it means has made its way from the skeptical 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 (does he still work for NASA? News to me - blog editor), says the lower
than expected temperature rise between 2000 and the present could be explained
by increased emissions from burning coal. (of course it could, but Occam's Razor demands the simplest answer, that the warmest's are wrong !!).
For Hansen the pause (i.e. the slowdown in global warming) is a fact, but it's good news that
probably won't last. (really? "They denied the slowdown at 8 years, then 10, then 16 years and, now, at the 20 year mark).
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. (well, are more than half way to that point in time, aren't we).
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.
[David] Whitehouse argues that whatever has happened to make
temperatures remain constant requires an explanation because the pause in
temperature rise has occurred despite a sharp increase in global carbon
emissions.
The Economist says the world has added roughly 100 billion
tonnes of carbon to the atmosphere between 2000 and 2010, about one-quarter of
all the carbon dioxide put there by humans since 1750. This mismatch between
rising greenhouse gas emissions and not-rising temperatures is among the
biggest puzzles in climate science just now, The Economist article says. (go to The Australian for the full article.)
