The amount of carbon dioxide in the air is growing at alarming rates and is now at levels not seen for millions of years, according to the UN.
The dangerous levels of CO2 could fuel a 20-metre rise in sea levels and add 3 degrees to temperatures, its World Meteorological Organisation said.
Levels are accelerating far faster than before, with last year’s growth more than 50 per cent above the average for the last decade. That has led CO2 levels to rise 45 per cent above pre-industrial levels and further outside the range of 180-280 ppm seen in recent cycles of ice ages and warmer periods.
