“A nightmare in the not-very-distant future: the map below shows the enormous temperature rises which British scientists believe the planet may be experiencing in as a little as 50 years from now if global warming remains unchecked. Released by the [UK] Government today, the map illustrates... a rise in global average temperature of four degrees Centigrade by 2060, and as such represents a dramatic acceleration of previous forecasts made as recently as 2007 by the UN’s Intergovernmental Panel on Climate Change (IPCC). …. Britain may see an average rise of three degrees – which itself would have very damaging consequences in terms of drought and extreme heatwaves – Siberia and northern Canada may experience an immense rise of 12 degrees or even more. Scientists believe this may trigger a climate “tipping point” – the melting of the permafrost under the northern tundras which, if it happened, would release large amounts of trapped methane gas, which in turn would boost global warming yet further. … Over the Arctic Ocean in the far north, the rise might be a colossal 15 or even 16 degrees, which would mean the complete disappearance of all the Arctic ice in summer and spell extinction for ice-dependent wildlife such as polar bears and walruses.
The map shows rises of five degrees in Asia, seven degrees in Africa and parts of the US and eight degrees in the Amazon rainforest, all of which will have devastating consequences for some of the world’s poorest people. Rises like this are likely to lead to maize and wheat yields falling by 40 per cent across the world, and rice yields in China, India, Banglasdesh and Indonesia falling by 30 per cent – all at a time when world population is expected to grow from 6.9 billion today to more than 9 billion people.
Water resources are likely to be severely affected by a 70 per cent reduction in run-off around the Mediterranean, southern Africa and large areas of South America, forest fires are likely to be much more dangerous everywhere and warming-induced sea-level rise will affect millions more people in low-lying nations such as Bangladesh.”
