Global Warming Fail

Drudge had linked to an article at the Australian discussing the 20-year "hiatus" in global warming. From the article:
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.
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.
"But it does not mean global warming is a delusion."
The fact is temperatures between 2000 and 2010 are still almost 1C above their level in the first decade of the 20th century.
"The mismatch might mean that for some unexplained reason there has been a temporary lag between more carbon dioxide and higher temperatures in 2000-2010.

"Or it might mean that the 1990s, when temperatures were rising fast, was the anomalous period."
What it means is that there are still too many questions remaining to support the imposition of wide-ranging political and economic policies, or refocusing of government and societal priorities. Unfortunately, like many other leftist delusions, global warming has become more than a scientific theory--it is a religion. And one that can bear no dissent, as this article at Forbes makes clear:
Fox News Channel apparently invited [Michael] Mann to appear on the air and debate climate scientist Roy Spencer on the topic of global warming. Roy Spencer, a principal research scientist at the University of Alabama in Huntsville, is one of the most knowledgeable climate scientists in the world. He has been a Senior Scientist for Climate Studies at NASA’s Marshall Space Flight Center, receiving NASA’s Exceptional Scientific Achievement Medal for his global temperature monitoring work with satellites. Spencer currently holds the position of U.S. Science Team leader for the Advanced Microwave Scanning Radiometer flying on NASA’s Aqua satellite. He is frequently invited to testify before Congress and in state legislatures regarding climate science.
Spencer’s scientific research leads him to be skeptical of the assertion that humans are causing a global warming crisis. He is also well-known among climate scientists for being an evangelical Christian.
Mann declined Fox News Channel’s invitation to debate Spencer. Not content to be a gracious invitee, Mann took to his Twitter account to pour out venom at Fox News Channel, Roy Spencer, and Spencer’s religious beliefs. “No, @FoxNews, I’m not interested in ‘debating’ #climatechange and #evolution denier Roy Spencer on your ‘news’ network,” wrote Mann.

Within the global warming debate, it is well understood that calling a global warming skeptic a “denier” is a deliberate attempt to demean and disrespect him or her on a personal level. Global warming skeptics were universally labeled “skeptics” until a handful of particularly aggressive warmists began drawing asserted links between global warming skeptics and “holocaust deniers.” Soon thereafter, the most aggressive warmists lumped the two groups together and began referring to global warming skeptics as “deniers.” Mann was quite aware of the insulting and disrespectful nature of the term when he called Spencer an “evolution denier.” Indeed, shortly after refusing to debate Spencer and calling him an “evolution denier,” Mann punctuated his use of deliberately disrespectful language by tweeting, “Getting on a debate stage signals that, while you might disagree, you respect the position of your opponent.”
