CO2 is Not a Pollutant but a Huge Benefactor

By Joseph D’Aleo, CCM, AMS Fellow
ICECAP, Aug 07, 2010

There is a wild debate in the skeptic community on whether CO2 plays a role in climate changes over time and if so how much. I am going to avoid getting embroiled in that discussion because no one knows, including the IPCC, which starts with the basic assumption that it does, that we understand the forcing and proceeds from there. They back into the forcing in their models which are seriously flawed with very poor understanding of the clearly important factors of water in all its forms in our atmosphere and in the role of the sun and oceans. Even with seriously contaminated surface observation data, their models are failing miserably even just a decade or two into the runs.

There was a very similar divisive argument in the meteorological community in early to middle part the last century as Dr James Fleming of Colby College documented in the book “Historical Perspectives on Climate Change”. The pertinent chapter was on the web and can be found here. This was before models and was based on theory as the write-up documents.

As a Synoptic Meteorologist and Climatologist over the years I have let the data do the talking. The data says that CO2 plays little or no role in climate change – which is cyclical and relates far better with the cycles in sun and ocean.

When correlating CO2 with temperature trends in various periods of cyclical warming and cooling the last 110 years we find a negative correlation from the late 1800s to 1917 (-0.35), positive from 1917 to 1940 (+0.43), negative during the WWII and post WWII boom from 1940 to around 1975 (-0.40), positive from 1975 to around 2000 (+0.36) and negative in the short period to 2009 (-0.56).

Indonesia’s Climate Follows the Sun


By Dr. Willie Soon and Lord Christopher Monckton

Carbon dioxide is not an air pollutant. It is plant food. All life on Earth depends on it. It is natural. It forms the bubbles in bread, champagne, and Coca-Cola. You breathe it out, and plants breathe it in. The Earth contains a lot of CO2, but the atmosphere contains so little that the United Nations’ Intergovernmental Panel on Climate Change (IPCC) rightly calls CO2 a “trace gas”. A scientific mystery is why the air does not hold more CO2 than it does. Half a billion years ago, there was almost 20 times today’s CO2 concentration.

Most farmers would prefer to grow crops under much-higher concentrations of CO2 than today’s 385 parts per million – less than 1/25 of 1 percent of the atmosphere. To feed the world, low CO2 concentration is not such a great idea. High concentrations are better, and they cause no harm. Experiments have shown that even delicate plants such as orchids thrive at CO2 concentrations of 10,000 ppm. That is why U.S. Supreme Court Justice Anthony Scalia has declared that if CO2 is to be labeled an “air pollutant”, then so must Frisbees and flatulence.

What about the danger of overheating the Earth by CO2? Al Gore is spending $300 million telling us “global warming” will be a catastrophe. Yet a survey of 539 scientific papers containing the words “global climate change” and published between January 2004 and February 2007 found not a single one that provided any evidence that “global warming” would be catastrophic. It does not matter how many scientists or politicians say that more CO2 will cause a catastrophe. To true scientists, what matters is whether any real-world data support the idea.

If CO2 is a powerful greenhouse gas, we would have seen a great warming trend in Indonesian temperature history. We haven’t. Recent temperatures, according to the Tyndall Centre for Climate Change Research, have been scarcely warmer than they were 70 to 100 years ago. Instead of a strong warming trend, the Indonesian data are dominated by year-to-year changes and natural oscillations every 50 to 100 years.


Look to matahari (the sun in Bahasa Indonesia) rather than CO2 as the key player in Indonesia’s climate. Read more here.

New Detailed Analysis of Global Temperature Data Does Not Support Significant Role for Carbon Dioxide

From Jennifer Marohasy’s Blog, October 5, 2008

The Intergovernmental Panel on Climate Change (IPCC) has stated that: Most of the observed increase in global average temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations, mainly carbon dioxide. This conclusion is based on output from global climate computer models known as General Circulation Models (GCM).

David Douglass and John Christy, in a paper recently accepted for publication and already available on the internet, have come to a different conclusion. By considering observed, as opposed to modelled, temperature changes and at different latitude bands they conclude that:

1. El Nino and La Nina effects in the tropics have a more significant affect on global temperature anomalies than carbon dioxide, in particular it was an El Nino event that drove the 1998 global temperature maximum.

2. Variations in global temperatures since 1978 have mostly been due to climate effects in the northern hemisphere (northern extratropics) and these effects cannot be attributed to carbon dioxide.

3. Carbon dioxide has contributed a small amount to an increase in global temperatures but without what is commonly referred to as feed-back.

Global warming: why cut one 3,000th of a degree?

From The Times, September 30, 2008

Britain’s efforts to reduce the speed of global warming will cost huge sums of money and have a pitifully tiny effect.

Global warming is seen everywhere as one of the most important issues. From the EU to the G8, leaders trip over one another to affirm their commitment to cutting CO2 to heal the world. What they do not often acknowledge – in part because it would lose them support – is that the solutions proffered are incredibly costly and will end up doing amazingly little good, even in a century’s time. This is the truly inconvenient truth of the politics of global warming.
