The American Association for the Advancement of Science (AAAS) has produced yet another report on climate change. The report states clearly that, based on the evidence, more than 97% of climate scientists agree that human-caused climate change is happening. When I first started at university almost 20 years ago, the nature of climate change was a live debate. However by the late 1990’s, when I graduated, the evidence had become overwhelming and the debate was settled. Since that time, more and more evidence has accumulated, but the policy makers have stopped listening, as we hurtle towards the cliff edge. NOW really is the time to put the brakes on climate change before it is too late…

For the record, I have a BSc in Ecological Science at The University of Edinburgh and an MPhil in Plant Ecology, my thesis was on the potential affects of climate change on mountain vegetation in Scotland, so I am in a position to know what I am talking about.
