Climate Tracker

Scientists have been warning, for over a decade, that atmospheric carbon dioxide (CO2) concentrations of more than 450 parts per million (ppm) risk triggering extreme weather events and global average temperatures more than 2 degrees C above pre-industrial levels, beyond which the effects of global heating are likely to become catastrophic and irreversible.

Carbon dioxide levels in February 2020 reached 416 ppm, with an associated temperature increase of nearly 1.4 degrees C. So time is running out and we are all now being challenged to limit this global heating to 1.5 degrees C, which is linked to a CO2 level of 430 ppm, if we are to avoid the worst impacts of climate change.
