Global Warming miscellany

1. Climate Realists report:
'India has once again challenged the UN's climate science body - the Intergovernmental Panel on Climate Change (IPCC) --- through a new scientific paper.

The Environment ministry sponsored paper says that human induced global warming is much less than what the R K Pachauri headed IPCC had said. The cause is reduced impact of Galactic Cosmic Rays (GCRs) on formulation of low clouds over earth in the last 150 years, says a paper by U R Rao, former chairman of Indian Space Research Organisation, released by Environment minister Jairam Ramesh.

The GCRs are the ones that enter solar system from outside, mostly from exploding of stars, and help in forming low-level clouds over the earth. The theory is that the solar magnetic field deflects GCRs, thereby impacting low-level cloud formation.

Analyzing the data between 1960 and 2005, Rao found that lesser GCRs were reaching the earth due to increase in solar magnetic field and thereby leading to increase in global warming.

"Consequently the contribution of increased CO2 emission to be observed global warming of 0.75 degree Celsius would only be 0.42 degree Celsius, considerably less than what predicted by IPCC," the paper said to be published in Indian Journal Current Science had said. This is about 44 % less than what IPCC had said.

Ramesh in 2009 had released a similar scientific paper saying that the IPCC's claim that most Himalayan glaciers will melt by 2035 was wrong. A few months later, after a review the IPCC regretted the error. If Ramesh latest bid gets globally recognition, it can alter the rules of UN run climate negotiations of 200 nations.'

2. Weather Action have a helpful round-up of articles regarding 'The Claim 2010 is '2nd warmest year on record' and explains why this 'is delusional, irrelevant & disingenuous – the last gasp of the failed global warming cult'

3. The Carbon Sense Coalition explain that
'CO2 is not a pollutant and it is not a poison and we should not corrupt the English language by depriving “pollutant” and “poison” of their original meaning.

Our exhaled breath contains about 4% CO2. That is 40,000 parts per million, or about 100 times the current atmospheric concentration. CO2 is absolutely essential for life on earth. Commercial greenhouse operators often use CO2 as a fertilizer to improve the health and growth rate of their plants. Plants, and our own primate ancestors evolved when the levels of atmospheric CO2 were about 1000 ppm, a level that we will probably not reach by burning fossil fuels, and far above our current level of about 380 ppm. We try to keep CO2 levels in our US Navy submarines no higher than 8,000 parts per million, about 20 times current atmospheric levels. Few adverse effects are observed at even higher levels.
