1. Smaller mountain glaciers disappear in Andes, threatening water supply of 50 million people. More than 300,000 people extra die from increase in climate-related diseases in tropical regions. Permafrost melting damages roads and buildings in Canada and Russia. One in ten species threatened with extinction, 80 per cent of coral suffers regular bleaching.
2. Water scarcity increases in Southern Africa and the Mediterranean. Significant decline in food production in Africa, where malaria affects up to 10 million more people. Arctic species, such as the polar bear, face extinction along with 15-40 per cent of the worlds remaining wildlife. Gulf Stream begins to weaken and Greenland ice sheet begins to melt irreversibly.
3. Serious droughts in the southern Europe occur once every ten years. Between 1 and 4 billion people suffer water shortages and a similar number suffer from floods. Many millions of people are at risk of malnutrition, as agricultural yields at higher latitudes reach peak output. More than 100 million people are effected by the risk of coastal flooding. Mass extinction of animals and plants accelerates.
4. Sub-Sahara Africa and the southern Mediterranean suffer between 30 and 50 per cent decrease in availability of water, Agricultural yields decline by 15-35 per cent in Africa. Crops fail in entire regions. Up to 80 million extra people are exposed to malaria. Loss of of around half the Arctic tundra. Many nature reserves collapse. Giant West Antarctic Ice Sheet begins to melt irreversibly, threatening catastrophic increases in global sea levels.
5. Possible disappearance of the large glaciers of the Himalayas, affecting the water supply of 25 per cent of population of China and hundreds of millions more in India. Ocean acidity increases with threat of total collapse in the global fisheries industry. Sea levels rise inexorably, inundating vast regions of Asia and about half of the worlds major cities, including London, New York and Tokyo.
