The Indian government has established its own body to monitor the effects of global warming because it “cannot rely” on the United Nations’ Intergovernmental Panel on Climate Change, the group headed by its own leading scientist Dr R.K Pachauri.

The move is a significant snub to both the IPCC and Dr Pachauri as he battles to defend his reputation following the revelation that his most recent climate change report included false claims that most of the Himalayan glaciers would melt away by 2035. Scientists believe it could take more than 300 years for the glaciers to disappear.

The body and its chairman have faced growing criticism ever since as questions have been raised on the credibility of their work and the rigour with which climate change claims are assessed. In India the false claims have heightened tensions between Dr Pachauri and the government, which had earlier questioned his glacial melting claims.

In Autumn, its environment minister Mr Jairam Ramesh said while glacial melting in the Himalayas was a real concern, there was evidence that some were actually advancing despite global warming.

There is a fine line between climate science and climate evangelism. I am for climate science. I think people misused [the] IPCC report, [the] IPCC doesn’t do the original research which is one of the weaknesses… they just take published literature and then they derive assessments, so we had goof-ups on Amazon forest, glaciers, snow peaks. “I respect the IPCC but India is a very large country and cannot depend only on [the] IPCC and so we have launched the Indian Network on Comprehensive Climate Change Assessment (INCCA),” he said.

It will bring together 125 research institutions throughout India, work with international bodies and operate as a “sort of Indian IPCC,” he added. The body, which he said will not rival the UN’s panel, will publish its own climate assessment in November this year, with reports on the Himalayas, India’s long coastline, the Western Ghat highlands and the north-eastern region close to the borders with Bangladesh, Burma, China and Nepal. “Through these we will demonstrate our commitment to climate science,” he said.

The UN panel’s claims of glacial meltdown by 2035 “was clearly out of place and didn’t have any scientific basis,” he said, while stressing the government remained concerned about the health of the Himalayan ice flows. “Most glaciers are melting, they are retreating, some glaciers, like the Siachen glacier, are advancing. But overall one can say incontrovertibly that the debris on our glaciers is very high the snow balance is very low. We have to be very cautious because of the water security particularly in north India which depends on the health of the Himalayan glaciers,” he added. The new National Institute of Himalayan Glaciology will be based in Dehradun, in Uttarakhand, and will monitor glacial changes and compare results with those from glaciers in Pakistan, Nepal and Bhutan.
