British Climate Secretary Ed Miliband warned Saturday night of the danger of a public backlash against the science of global warming in the face of continuing claims that experts have manipulated data.

In an exclusive interview with the Observer, Miliband spoke out for the first time about last month's revelations that climate scientists had withheld and covered up information and the apology made by the influential United Nations  Intergovernmental Panel on Climate Change (IPCC), which admitted it had exaggerated claims about the melting of Himalayan glaciers. 

The perceived failure of global talks in Copenhagen last month on combating climate change has also been blamed for undermining public support. Yet, in the government's first high-level recognition of the growing pressure on public opinion, Miliband declared a "battle" against the "siren voices" who denied global warming was real or caused by humans, or that there was a need to cut carbon emissions to tackle it.

"It's right that there's rigor applied to all the reports about climate change, but I think it would be wrong that when a mistake is made it's somehow used to undermine the overwhelming picture that's there," he said.

"We know there's a physical effect of carbon dioxide in the atmosphere leading to higher temperatures, that's a question of physics; we know CO2 concentrations are at their highest for 6,000 years; we know there are observed increases in temperatures; and we know there are observed effects that point to the existence of human-made climate change. That's what the vast majority of scientists tell us."
