if we continue to burn fossil fuels at current rates, levels of carbon dioxide in the atmosphere will reach 550 ppm (parts per million) - double the pre-industrial levels - by around 2050. the intergovernmental panel on climate change said this would increase global temperatures by between 1.4 and 5.8°C by 2100, and that sea levels would rise by between 0.09 and 0.88 metres. this will lead to…
the melting of the greenland ice sheet, which holds about 2.6 million cubic kilometres of fresh water (around 6% of the world’s supply). with a 3°C rise in temp it will begin releasing all that water into the north atlantic ocean. according to scientists, sea levels around the world would rise at 5mm a year (compared with 1-2mm a year at the moment).
here’s an interactive guide to the issues
should we be concerned? do you live near the coast? can anything be done? by countries? governments? us? individuals?
