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.

Senator James Inhofe Rehashed Skeptic Screed Getting Old

He may only be part of a noisy minority, but Sen. James Inhofe (R-OK) isn’t about to let his fringe status get in the way of his latest skeptic shtick.

As he did last year, Inhofe, writing under the guise of the Minority on the Senate Committee on Environment & Public Works, has penned another anti-global warming screed with the help of his staffer, Marc Morano, entitled “UN Blowback: More than 650 International Scientists Dissent over Man-Made Global Warming Claims”. And, like last year, Inhofe’s laughable attempt at a serious “report” falls flat on its face upon any close scrutiny.

While there is much that could be singled out for ridicule in the senator’s report, I’ll focus on what I’ll call the skeptics’ “greatest hits” (i.e. the wrong-headed arguments they’ve been trotting out for months, if not years, to “prove” their point).

Let’s start with the claim made in the report’s title: that “half of warming” is due to solar forcing.

Despite being debunked over and over again, skeptics like Inhofe have latched onto a few studies published during the last decade that purported to show a link between solar activity – cosmic rays, in particular – and rising greenhouse gas emissions. (The idea being that cosmic rays helped water droplets form in the atmosphere, leading to increased cloud clover and, thus, lower average temperatures.)

Bush's Midnight Regulations: The Worse Is Yet to Come

Reports of the president’s lame duck status – his impotence, if you will – have been vastly exaggerated. Even as he has all but given up on rescuing the faltering economy (which, given his track record, isn’t necessarily a bad thing), he and his advisers have been redoubling their efforts to squash what is left of his predecessors’ environmental legacy.

Climate Change: It's Worse than You Think

Even if you aren’t a dyed in the wool environmentalist, it’s hard not to feel at least somewhat giddy at the prospects of what an Obama presidency could do for climate change.

During the electoral campaign, Obama repeatedly said that he would consider climate change and energy two of his administration’s top priorities. When pressed on the urgency of the economic crisis and the yawning federal deficit, he refused to buckle – arguing that the climate crisis was too critical an issue to kick down the road again.

In the wake of his memorable speech at the Global Climate Summit, only a hardened cynic would dismiss his climate advocacy as an opportunistic campaign ploy.

And, with the recent elevation of Rep. Henry Waxman (D-CA) to the chairmanship of the House Energy and Commerce Committee (replacing long-serving Rep. John Dingell, the notoriously pro-Detroit, regulation-leery Democrat), there’s reason to believe President-elect Obama’s first term could see significant progress on this front.
