Renowned Climatologist: ‘You can go outside and spit and have the same effect as doubling carbon dioxide’

‘Scientists note that geologically speaking, the Earth is currently in a ‘CO2 famine and that the geologic record reveals that ice ages have occurred when CO2 was at 2000 ppm to as high as 8000 ppm. In addition, peer-reviewed studies have documented that there have been temperatures similar to the present day on Earth when carbon dioxide was up to twenty times higher than today’s levels’

The level of carbon dioxide, a trace essential gas in the atmosphere that humans exhale from our mouths, has come very close to reaching the “symbolic” 400 parts per million (ppm) threshold in the atmosphere. Former Vice President Al Gore declared the 400 ppm level “A sad milestone. A call to action.”  New York times reporter Justin Gillis compared trace amounts of CO2 to “a tiny bit of arsenic or cobra venom” and warned that rising CO2 means “the fate of the earth hangs in the balance.” The New Yorker Magazine declared “Everything we use that emits carbon dioxide needs to be replaced with something that doesn’t.”  And a UK Guardian editorial declared “Swift political action can avert a carbon dioxide crisis.” (more…)

My Global Warming Skepticism, for Dummies

by Roy Spencer, Ph.D.

I receive many e-mails, and a recurring complaint is that many of my posts are too technical to understand. This morning’s installment arrived with the subject line, “Please Talk to Us”, and suggested I provide short, concise, easily understood summaries and explanations “for dummies”.

So, here’s a list of basic climate change questions, and brief answers based upon what I know today. I might update them as I receive suggestions and comments. I will also be adding links to other sources, and some visual aids, as appropriate. (more…)

New SPPI Paper on NRDC’s Ocean Acidification Scare Film

Wednesday, January 6th, 2010

by Robert Ferguson

The new SPPI paper can be found here: http://scienceandpublicpolicy.org/originals/acid_test.html

Reproduced here is the Foreword to the paper.

“OCEAN ACIDIFICATION” – THE EXTREMISTS’ FALLBACK SCARE

First, they called it “global warming”. Then they noticed there had been no warming for 15 years, and cooling for 9, so they hastily renamed it “climate change”. Then they noticed the climate was changing no more than it ever had, so they tried “energy security”, and even named a Congressional Bill after it. Then they noticed that most Western nations already had bountiful energy security, in the form of vast, untapped domestic supplies of oil, gas, coal, or all three, so they switched to “ocean acidification”.

This is the new phantasmagoric for the tired, old scare whipped up by the NRDC and the environmental extremist movement for their own profit at our expense. The world’s corals, they tell us, will be eaten away by the acidified ocean within not more than ten years hence. Shellfish will be no more, their calcified carapaces and exoskeletons dissolved by the carbonic acid caused by our burning of fossil fuels. The oceans will die. Sound familiar?

Yet, as the indefatigable Craig Idso here demonstrates, the scientific consensus – if science were done by consensus at all, which it is not – is that the rising “ocean acidification” scare is just more piffle. (more…)

CO2 – a bit-part player in ‘global warming’

Monday, January 4th, 2010

From The Viscount Monckton of Brenchley

  • A reader has asked us four questions about CO2 and its role in warming the Earth. We are always delighted to answer questions about the science and economics of “global warming”.

Dear SPPI, – I enjoyed your article debunking the peculiarly unscientific position of Scientific American.  I first heard of the “global warming” theory from my Advanced Physical Chemistry professor at Penn State University in the late 1960’s and wondered if his background in theoretical chemistry and easily-controlled-solution chemistry would let him understand a very complex atmospheric environment.  I also later learned that his vision of a hydrogen economy, and a few patents, was the major driving force.  I wonder if you could clarify a few of my assumptions.

1.    While I do find it difficult to get data, it seems to me that annual anthropogenic CO2 production is less than 1% of the current atmospheric levels.

2.   I have read that the first 20 ppmv of CO2 in the atmosphere provides the most IR absorption and thus greenhouse effect with the contribution declining rapidly thereafter.  This seems to me to mean that any increase, whatever its source, over the last 100 years would have little additional greenhouse effect.  I have seen someone suggest that doubling CO2 would have less than a 2% increase.

3.   Does anyone really know the capacity of plants and ocean flora to take up any increase and act as a stabilizing influence that could easily compensate for the small anthropogenic increase?  Or other sinks like formation of shells in mollusks and crustacean and other carbonates?

4.   If currently 98% of CO2 is dissolved in bodies of water that is far from saturation, wouldn’t at equilibrium 98% of any anthropogenic CO2 be there and not in the atmosphere?  Doesn’t that mean that doubling or even another 25% increase in atmospheric levels would require much more human production?
