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.

Cosmic rays contribute 40 p.c. to global warming: study
By Priscilla Jebaraj,

A key belief of climate science theology — that a reduction in carbon emissions will take care of the bulk of global warming — has been questioned in a scientific paper released by the Environment Ministry on Monday.
Physicist and the former ISRO chairman, U.R. Rao, has calculated that cosmic rays — which, unlike carbon emissions, cannot be controlled by human activity — have a much larger impact on climate change than The Intergovernmental Panel on Climate Change (IPCC) claims.
In fact, the contribution of decreasing cosmic ray activity to climate change is almost 40 per cent, argues Dr. Rao in a paper which has been accepted for publication in Current Science, the preeminent Indian science journal. The IPCC model, on the other hand, says that the contribution of carbon emissions is over 90 per cent.
Put up or shut up on global warming

It is time for an independent investigation of whether or to what degree human activities are creating catastrophic global warming. It should be conducted by scientists untainted by advocacy and uncompromised through receiving taxes or private funding to advance or debunk the theory.
Many in the new Congress were elected on promises to re-evaluate global warming claims used to justify Draconian regulations. A "team of nongovernment and non-U.N. experts must be established with access to all the raw data, records, adjustments, fudges ... and computer codes currently being black-boxed by government scientists," says Robert Ferguson, president of the nonprofit Science and Public Policy Institute for "sound public policy based on sound science." We agree.
NASA and the National Oceanic and Atmospheric Administration have resisted Freedom of Information Act requests for release of unadjusted raw data and documentation of their adjustments to them. Good science requires theories be tested.
