Nearly three-quarters of Conservative MPs do not accept that climate change has been proven to be caused by human activity, according to a new poll. The survey of 119 MPs from all parties was commissioned by PRWeek from Populus to establish the attitudes of parliamentarians to climate change and environmental issues as part of a special report on the subject. Only 51 per cent of MPs agree that it is an established fact that global warming is largely man made, though there are substantial differences between parties. A further 18 per cent agree that “man-made climate change is environmentalist propaganda”. --Alex Benady and John Owens, PRWeek, 10 September 2014
