Climate change is set to pass the milestone of 1C of warming since pre-industrial times by the end of 2015, representing “uncharted territory” according to scientists at the UK’s Met Office.

2015 is also set to be the hottest on record, as the temperatures are so far beating past records “by a country mile”, they said. The World Meteorological Organization further announced on Monday that 2016 would be the first year in which the concentration of carbon dioxide in the atmosphere is over 400ppm on average, due to the continued burning of fossil fuels.

The trio of landmarks comes just three weeks ahead of a crunch UN summit in Paris where world leaders including Barack Obama, Xi Jinping and David Cameron meet in Paris in a bid to reach a new deal on cutting emissions
