The Guardian editorial on the 2018 IPCC Report “Global warming of 1.5 °C” (2018): “Climate change is an existential threat to the human race… The latest report of the Intergovernmental Panel on Climate Change tells us that there are only a dozen or so years in which to change our economies radically if we are to keep the effects of the warming already under way to manageable proportions. That would require the countries of the world to live up to the most ambitious of the goals of the Paris climate change agreement, and keep the rise in average global temperatures to 1.5C above preindustrial levels. A rise of even half a degree above that, to 2C, will have effects that are very much worse. Already this seems much more likely. All corals will disappear, as will many insects and plants… All these risks make it quite credible that we will end with a warming of 3C, 4C or even worse – and the consequences will be globally terrible, and everywhere unavoidable. Hundreds of millions of people may die through droughts on land, and flooding at the coasts, through the loss of marine species due to acidification of the oceans, and probably through the disruption of long-term weather patterns around which the world’s agriculture has been shaped.” (The Guardian, Editorial, “The Guardian view on climate change: a global emergency”, The Guardian, 9 October 2018: https://www.theguardian.com/commentisfree/2018/oct/08/the-guardian-view-on-climate-change-a-global-emergency ).
