The main greenhouse gas emissions driving climate change have all reached record levels, the UN’s meteorology experts have reported.

Carbon dioxide, methane and nitrous oxide are now far above pre-industrial levels, with no sign of a reversal of the upward trend, a World Meteorological Organization report says.

“The last time the Earth experienced a comparable concentration of CO2 was 3-5m years ago, when the temperature was 2-3C warmer and sea level was 10-20 metres higher than now,” said the WMO secretary general, Petteri Taalas.

“The science is clear. Without rapid cuts in CO2 and other greenhouse gases, climate change will have increasingly destructive and irreversible impacts on life on Earth. The window of opportunity for action is almost closed.”

1. It's not like this can meaningfully change.

There’s no scenario that’s achievable where he don’t have record concentrations in the atmosphere for the foreseeable future.

2. Handy headline - just plug it in every year with new numbers

Convenient!
