CLIMATE change is the most important political issue of our generation. There’s 99 per cent scientific consensus that humans are causing global warming and that, unless we stop putting greenhouse gases in the atmosphere, life on Earth will become increasingly unviable. 

If we continue at the current trajectory in terms of greenhouse gas emissions, we’re facing over 4°C of warming by the year 2100.

David Wallace-Wells writes in his book The Uninhabitable Earth: A Story of the Future that, “according to some estimates, that would mean that whole regions of Africa and Australia and the United States, parts of South America north of Patagonia, and Asia south of Siberia would be rendered uninhabitable by direct heat, desertification, and flooding.”
