Warmist Bob Ward writes in The Independent:
David Cameron will face another challenge to his authority and credibility as a world leader today when Conservative MPs call for the UK to abandon its targets for reducing greenhouse gas emissions.
David Davies, the MP for Monmouth, and his other backbench colleagues will call during a debate in Westminster Hall for the Government to review the Climate Change Act, which commits the UK to cut its emissions by at least 80 per cent by 2050 compared with 1990.
The Act, which was passed in the House of Commons by an overwhelming majority in 2008 when only 5 MPs voted against it, is regarded around the world as a model of evidence-based climate change policy.
It is intended to ensure that the UK plays its part in international efforts to avoid global average temperature increasing more than 2°C above the level it was at before the Industrial Revolution, when widespread burning of fossil fuels started to dump large volumes of carbon dioxide into the atmosphere.
The last time global average temperature were more than 2°C above the pre-industrial level was 3 million years ago, during the Pliocene Epoch, when the polar ice caps were much smaller and global sea level was about 20 metres higher than today.
But Mr Davies, who voted for the Act five years ago, now questions the need for the emissions target and disputes scientists’ explanations of the causes of climate change.
