We Won’t Stop . .

. . till we have concreted the whole planet and burnt the last scuttle of coal and barrel of oil.

We won’t.

The concentration of carbon dioxide in the atmosphere hit 415 parts per million (ppm) last week for the first time in 800 000 years. Scientists have warned that the world must keep CO2 emissions below 350 ppm to avoid dangerous levels of climate change – but emissions keep rising.

The record high was measured on May 3 at the Mauna Loa Observatory in Hawaii, part of the US National Oceanic and Atmospheric Administration (NOAA) global monitoring division.

This is the highest level recorded at this station since it began keeping records in 1959. Analysis of the ice cores in Antarctica show that over the last 800 000 years the CO2 levels in the atmosphere fluctuated between 170 ppm and 300ppm.

Climate organisations say this record high level is a strong indicator that governments must take climate change seriously and move away from fossil fuels. 

We won’t. Our grandkids will wonder why.
