Transparency needed on donors to climate sceptic lobby

Science is by its nature sceptical: scientists interrogate information and only on repeated investigation does data become science. The science of climate change has been established through numerous high-profile studies (IPCC, NOAA, Nasa) and was even verified by the sceptic-ledBest report. In 2009 one of the world's leading medical journals, the Lancet, declared climate change "the biggest global health threat of the 21st century". Denying the links between greenhouse gas emissions and man-made climate change is akin to denying the links between HIV/Aids and unprotected sex, smoking and lung cancer, or alcohol consumption and liver disease. In each of these cases, well-funded deniers have had to be exposed and confronted before appropriate health-promoting legislation was put in place.

The Climate and Health Council supports Nasa scientist James Hansenas he joins the campaign to uncover secret funders bankrolling climate sceptic Nigel Lawson and his lobbying think-tank (Climate experts back unveiling of Lawson thinktank donor, 23 January). The public may finally discover who is secretly influencing UK climate policy – contrary to scientific consensus – today (27 January), when the Information Rights Tribunal hears this key freedom of information case. Some anti-climate lobbyists routinely misrepresent and cast doubt on the work of climate scientists. Although Lawson and his Global Warming Policy Foundationhave been discredited and attacked by numerous scientists and senior politicians, his thinktank continues to receive significant coverage, wrongfully distorting the public and policy debate over climate change.

Perverting the course of evidence-based policy on climate-change adaptation and mitigation damages our health resilience, our economic prosperity and our environmental stability. Transparency around climate-sceptic funders is essential. We support freedom of information to reveal those deliberately preventing the UK's sustainable future.
