Most climate denial material is all over the map so it is a pleasant change to have a nice clear target.

I am talking about the "Skeptic’s Handbook" that the notorious Heartland Institute is helpfully printing 150,000 copies of for distribution across the US including 850 journalists, 26,000 schools, “19,000 leaders and politicians”.

The mass printing of this climate propaganda piece is being funded by an “anonymous donor”. It is odd that “someone” feels strongly enough to shell out that kind of money but also wants their identity concealed. We do know that the Heartland Institute has been bankrolled to the tune of $676,000 from ExxonMobil since 1998. Nuff said.

It is also interesting that this latest product of the denial machine is washing over the nation less than a month after the US government released their Climate Change Literacy brochure – cosigned by 13 federal agencies and 24 educational and scientific partners.

Membership in the supposed climate change conspiracy now includes such well known eco-freaks as the Department of Defense, the Department of the Interior and the US Forest Service.

The handbook itself is hilariously illogical. It coaches “skeptics” to avoid talking about the evidence of changing climate - for obvious reasons presumably. According to them, something may be heating things up, its just not carbon dioxide. Independent thinkers are instead counseled to follow these four cookbook points:

• The greenhouse signature is missing
• Ice Cores do not support carbon as a driver of climate change
• Temperatures are not rising
• Carbon dioxide is doing almost all the warming it can do.

All of these points are either entirely wrong or grossly misleading. Lets get out the shovel and start unloading this pile of manure.

This is my final posting debunking professional climate denier Joanne Nova’s “The Skeptics Handbook.”

Nova's final pseudo-scientific arguments is greenhouse signature.

The greenhouse signature argument boils down to the following:

Because weather balloons haven’t yet been able to locate the “hot spot” – a patch of air above the tropics that should show signs of greenhouse gas-induced warming (hence, the greenhouse “signature”) – there must be something else causing the warming. This was somehow also proof that the models had it all wrong – since they had predicted that, in the tropics, the warming of the troposphere should have been larger than that of the surface.

Today we'll look at two more of the (supposedly) bullet-proof points in Joanne Nova’s “The Skeptics Handbook.”

"Professional Speaker" turned climate expert Nova rehashes two of the more common skeptic talking points, that: the world is no longer warming and the Vostok ice core record proves that rising CO2 emissions are not the cause of warmer temperatures.

As skeptics love to point out, the planet has not appreciably warmed over the last decade even though carbon dioxide levels have greatly increased. While it’s true that surface temperatures have remained essentially flat over the last 10 years, taking such a myopic view of the temperature record obscures the much more meaningful long-term trends.

Indeed, if you look at the temperature record of the last 150 years or so, you’ll find it extremely hard not to notice the obvious upward trend (there’s a reason why the nine warmest years on record have all occurred between 1998 and 2008).
