Levels of the most significant planet-warming gas in our atmosphere rose more quickly than ever previously recorded last year, scientists say, leaving a key global climate target hanging by a thread. Concentrations of carbon dioxide (CO2) are now more than 50% higher than before humans started burning large amounts of fossil fuels.

Carbon dioxide in the atmosphere is increasing at rates that are incompatible with staying below 1.5 degrees Celsius (34.7 degrees Fahrenheit) of global warming, a Met Office study warns.
