Here is a list of the inaccuracies in the Climate Skeptic’s Hanbook [PDF]  authored by “professional speaker” Joann Nova.
The Climate Skeptic’s 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.
1. The greenhouse signature is missing
Flat out wrong.
There is a clear signature  that greenhouse gases are warming the atmosphere and has been for years. If you thought that the scientific community had picked over this issue pretty carefully for about 100 years, you would be right. Hundreds of studies have looked at this question using mathematical analysis, laboratory studies and atmospheric observation. Modeling based on this data agrees very well  with what we are seeing.
There are several drivers of temperature change on Earth, including atmospheric sulfates, volcanic ash, fluctuations in the ozone layer, changes in the Sun and greenhouse gases. Here’s what the modeling and direct observations shows:
As a matter of fact, the warming profile  of the atmosphere is exactly what you would expect from the greenhouse effect due to carbon emissions – namely a hotter lower atmosphere and a colder stratosphere. Sorry deniers – that one is tossed in the tank yet again.
2. Ice Cores do not support carbon as a driver
Ice core data shows a very strong link  between atmospheric carbon and global temperatures. What the deniers are harping on is that it appears that carbon does not start the warming, it only amplifies it .
Believe me, this is nothing to take comfort  from.
Ice core data dating back hundreds of thousands  of years clearly shows that once warming is started due to regular fluctuations in the Earth’s orbit or solar output, it leads to massive increases in atmospheric CO2 from melting permafrost and release from the oceans. This in turn leads to positive feedbacks that amplify warming by up to five times.
The difference now is that we are jump-starting the warming by dumping huge amounts of ancient carbon into the atmosphere by burning fossil fuels. This is already leading to positive feedbacks  like melting permafrost, and increased forest fires. The other scary difference is that scientists believe that this time we may push past tipping points like melting the Greenland ice sheet  that the planet has not seen in a long, long time. Sound like a good idea? Maybe we shouldn’t give it a try.
It is also amussing that deniers say that atmospheric carbon dioxide has nothing to do with warming, while also maintaining that it does, but it dosn’t matter. You try and figure out what they are saying - I can’t.
3. Temperatures are not rising
Again, completely incorrect. The clear trend is upwards and has been since about 1900 with a large increase since 1980. Here is the latest world land temperature graph from NASA – decide for yourself whether things are getting chillier.
What climate deniers love to do is cherry pick the data by starting counting in 1998 – the warmest year in the history of meteorology and one of the strongest El Nino  years on record.
Another hoary old myth is the urban heat island  effect – that weather stations that used to be far off in the country are now in the city surrounded by pavement and air conditioners. Believe it or not, scientists actually thought of that .
Still don’t believe the entire scientific community? Have a look at the latest graph of global temperatures for both land and oceans. Not many air conditioners floating around sea.
4. Carbon dioxide is doing almost all the warming it can do
Absolutely false. Saying increased atmospheric carbon is not going to make a difference is like suggesting that throwing more wood on a fire will not make it bigger.
It is true that high school physics shows that CO2 warming in the atmosphere follows a logarithmic relationship – meaning that heating from increasing CO2  does not follow a straight line. That is precisely why scientists instead talk about an atmospheric doubling of CO2 (yes, they’ve thought of that  too).
Climate models predict that every additional doubling will lead to global warming of about 3°C  – but some estimates put it as high as 6°C. I guess we’ll find out…
In the last 150 years, we have increased atmospheric carbon  from 280 ppm to 385 ppm, and the pace is picking up speed . We are on track to hit 530 ppm by 2050 . To see what all these numbers mean, have a look at this animation  from the Bjerknes Centre for Climate Research in Norway.
Of course any real scientist making such ridiculous arguments among their peers would be laughed out of the room. That is why you will never ever see climate deniers make such absurd claims in the scientific literature – only in the mainstream media. Meanwhile the voting public remains dangerously confused  by this garbage. As they say, tick tock goes the clock .
The Denier’s Handbook was written not by a practicing researcher of course, but by a woman named Jo Nova whose past vocations included hosting of children’s program in Australia and touring Australia with a “science circus ” sponsored by Shell Oil.
Interesting, her former funder (the oil company) is no longer denying the link between carbon emissions and climate change in their communications with kids . Maybe she didn’t get the memo.
She has at least one science-related publication to her credit: Serious Science Party Tricks  ($14.95 AUD plus $2.50 postage). It does not directly relate to atmospheric chemistry however. It instead documents how to:
“Do the funniest, silliest, and most surprising tricks with things like paper, balloons, straws and flour. Simple, quick, easy and stunning. An activity book to keep you engrossed for hours!”
Hardly peer-reviewed stuff. I do not mean to disparage children’s literature, but these patently false claims are going to be distributed to 16,000 decision-makers and politicians and frankly she is asking for it.
It is also interesting that almost all of these augments seem to originate from our “rocket scientist ” friend David Evans. Real climate scientists in Australia were tearing their hair out when he kept popping up in the media Down-Under claiming to have an expertise in climate science. FYI – he has not published one single peer-reviewed paper in the field.
For some excellent critiques of these old and erroneous talking points see the blog of Dr. Barry Brook , an actual climate scientist from the University of Adelaide, and Dr. David Karoly  at the University of Melbourne. There are good eviscerations of Nova’s “arguments” here .
The old field of climate scince misinformation blooms anew – well fertilized by ““anonymous donors” and of course the fossil fuel industry.
