If we do not take rapid and decisive action to mitigate climate change, it is quite realistic that by 2050, it will be a direct existential threat to mankind – writes CNN on a new report.
The report (pdf) quoted by the Australian think tank, Breakthrough National Center for Climate Restoration, is not based on new research, but on possible future scenarios based on previous scientific findings. And he outlines a lot of hilarious events: unbearable heat, deserted cities, one billion homeless people, collapsing food industry, collapsing ecosystems.
According to the report, if the scenario that global temperatures rise by 3 degrees Celsius by 2050 compared to the pre-industrial revolution, then
55 per cent of the world’s population on 35 per cent of land areas would have to cope with the heat that is already “beyond human survival” for more than 20 days;
In West Africa, South America, the Middle East and Southeast Asia, more than 100 deaths a year would result in more than one billion people moving elsewhere;
due to the rising sea level, many metropolitan areas in the world, including Mumbai, Jakarta, Shanghai, Guangzhou, Hong Kong, Ho Chi Minh City, Bangkok and Manila, would be depopulated and only 15 million people from Bangladesh should be relocated;
food production is collapsing as the number of agriculturally important insects is catastrophically wasted;
several major ecosystems in the world would collapse, such as those on the North Pole, the Amazonian and the Coral Reefs.
The foreword of the report was written by Chris Barrie, former commander of the Australian Army, who said “after the nuclear war, man-made global warming is the greatest threat to mankind on the planet”. He adds that the judgment day outlined in the report as a realistic possibility is not inevitable today, but if we do not go immediately, our prospects are rather weak. The report is written by David Spratt and Ian Dunlop, both of whom are climate researchers, but Dunlop has previously held international managerial positions in the fossil industry and led the Australian coal industry, so he had an insight on the other side of the problem.
Andrew King, of the University of Melbourne, who did not participate in the report, said that although it does not matter that human civilization would end in 2050, the findings of the report are realistic and indeed a great existential challenge. According to him, all the problems mentioned in the report, such as mass relocations or food shortages, are likely to occur by 2050, but the question is how widely they will be. In addition to climate change, the exact scenario depends on a number of additional factors, such as population growth.
