Cosmic rays "contribute 40% to global warming"

Cosmic ray shower

From The Science is Settled Department. This is what happens when you decide on a pre-conceived politically-motivated conclusion (that man-made CO2 is solely to blame for climate change) and then set up an entire bureaucracy (the IPCC) to build a scientific case to support it. You only look at matters that will support your case, and you shut your eyes to anything that might challenge that case – and the result is not science at all.

So it’s little wonder that independent researchers who have no political axe to grind are constantly making discoveries about the climate that the consensus boys don’t want to hear. Like this:

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.

‘Cosmic ray impact ignored’

Releasing Dr. Rao’s findings as a discussion paper on Thursday, Environment Minister Jairam Ramesh noted that “the impact of cosmic ray intensity on climate change has thus far been largely ignored by the mainstream scientific consensus.” He added that the “unidimensional focus” on carbon emissions by most Western countries put additional pressure on countries like India in international climate negotiations.

The continuing increase in solar activity has caused a 9 per cent decrease in cosmic ray intensity over the last 150 years, which results in less cloud cover, which in turn results in less albedo radiation being reflected back to the space, causing an increase in the Earth’s surface temperature.

Expect to see this story reported widely on the ABC and in Fairfax…


  1. You’re kidding, right? I doubt it’ll be reported anywhere mainstream, at least not prominently

  2. Very interesting that Henrik Svensmark’s hypothesis has made it to India. Now here’s a conundrum: how could anyone explain to Mr Combet in a way he could accept it?

    I’ve not looked at it in detail myself, but I have looked at the intensity and length of solar cycles, and they really do blow away any mere greenhouse gas when explaining the temperature record. So maybe this is the linking mechanism? I should go find and read the paper I suppose.
