2008 Third Worst Year for Weather-related Insurance Claims

Climate change has already started and is very probably contributing to increasingly frequent weather extremes and ensuing natural catastrophes.”

Once again the world’s foremost risk analysts (the leading lights in the international reinsurance industry) have offered up their analysis confirming the gathering risks from global warming. The New York Times Business Page has the news here.

Debunking Joanne Nova's 'Skeptics Handbook' part 3: The Climate Models Have it Right

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.

Debunking Joanne Nova's 'Skeptics Handbook' part 2: Yes, Global Warming is Real and it's Still Happening

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).

Debunking the 'Skeptics Handbook': More CO2 Does Worsen Climate Change

If you were to take the sum “knowledge” of global warming skeptics and distill it into a short, quasi-readable manifesto, you’d end up with something like Joanne Nova’s “The Skeptics Handbook.”

For someone who claims to have been a “veteran believer in greenhouse gases from 1990 – 2007,” Nova sure has a way of rehashing a lot of the same old tired arguments that climate scientists have been shooting down for years – particularly her central point that there is no evidence to link rising carbon dioxide emissions to higher temperatures (more on that later).

Perhaps the most odious aspect of this handbook is that it seems to be aimed squarely at a younger audience – what with its dumbing down of the science and constant repetition of the same flawed arguments. Having failed to gain ground with the adults, the skeptics are presumably turning to the younger generations now to carry their water.

While I’d encourage anyone who wants a substantive discussion of the science behind climate change to go consult the experts (actual scientists like the Real Climate blogger team, for example) – a revolutionary concept, I know – I’ll do my best to debunk some of Nova’s most egregious arguments over the next few days. I’ll get things started today with her “bottom line”: that adding more CO2 to the atmosphere does not cause global warming.

The easiest way to dismiss this point, as Grist contributor and Texas A&M University Professor Andrew Dessler noted, is to look at Venus’ atmosphere. Though it shares several features in common with our planet – hence its sometimes being called Earth’s “sister planet” – it differs in one crucial aspect: the amount of CO2 in its atmosphere.

Todd Carmichael has made it to the South Pole!

We have just got word that American expeditionist and DeSmogBlog writer Todd Carmichael has made it to the South Pole. This makes Todd the very first American ever to reach the South Pole solo and unaided.

And to top it off, Todd has set a new time speed record!

Todd has been writing on DeSmogBlog and Huffington Post for the last year raising awarness about the negative impacts of human-caused global warming on the Antarctica. Here’s one of his most popular pieces: Something Strange is Happening at the Coldest, Driest Place on Earth

Wayne Moore, a physician’s assistant working at the South Pole, sends an update about Todd via the guestbook on this site: “To all his very concerned friends & family, he has made a rapid recovery from the trip and has become a local hero at the station.” Thanks very much for the word Wayne! Besides being an astronaut, I can’t think of anything cooler than working in Antarctica. Cheers to you and everyone else down there.

Now that you’re a hero Todd, you can get back to work helping us!

But seriously, we met Todd about a year ago when he asked if he could write on DeSmogBlog to help promote solutions to reducing greenhouse gas. After a cursory glance at his credentials we quickly obliged. In fact, we even made Todd his own section on the site.

Todd is one of those amazing people you read about that dream big and make the best of everything that life has to offer. The whole DeSmogBlog team is proud to be associated with Todd and really, really hope that he doesn’t come back from his trek too famous to write for us once in a while.

So over this holiday season when you pop a champagne cork, make sure one is dedicated to Todd.
