Watching the political news coming out of the US is often mind boggling, especially when it involves the Republican Party, AKA the Grand Old Party (GOP), or Fox News, or that complete mentalist Rush Limbaugh. When I first saw statements coming from these sources, I thought it was some sort of surrealist performance art parody of Monty Python. Alas, the whole thing is not a hoax. These people are real and very serious about their own myth making.
For years they have been denying that manmade climate change is real or can be proven, despite overwhelming evidence from climate scientists. During that time we have gone “beyond the limits” of what the Earth can manage in terms of being able to sustain an ever expanding population of humans. Even as I write there are over 200 fires raging in Alaska, a terrific heatwave causing mass deaths in India, crippling drought in large parts of South, Central and North America. The list of extreme weather events goes on and millions of people are suffering worldwide.
Professor David MacKay is the former Chief Scientific Advisor to the UK Government Department of Energy and Climate Change (DECC). In this important presentation Professor MacKay demonstrates how summers in the coming decades are going to be more extreme than what we are experiencing now, even giving examples of the summer of 2013 where thousands of people died in Europe from the heat.
This presentation gives a view into what 2ºC warming really means.
Lord Rees explains how governments can lead the world in an energy revolution that would change the course of human civilisation by making renewables cheaper than coal within a decade.
Martin Rees says: “Everyone agrees that if the warming gets too severe the net harms will grossly overwhelm the net gains and that’s why it’s been supposed by most people that a 2ºC limit is what we should strive for.”
