Four climate change indicators reached new highs in 2021: WMO
> Science
The ‘State of the Global Climate’ report has just been released by the World Meteorological Organization and it reveals that four key climate change indicators — greenhouse gas concentrations, sea level rise, ocean heat and ocean acidification — set new records in 2021.
The report confirmed that the past seven years have been the warmest years on record and while we the Earth did experience a temporary cooling effect due to the phenomenon of ‘La Nina’ at the start and end of 2021, this has not reversed the overall warming trend.
Carbon dioxide concentrations reached a new global high in 2020, reaching 413.2 parts per million (ppm) – 149 per cent of the pre-industrial level.
Oceans too experienced at least one ‘strong’ marine heat wave at some point in 2021 and droughts affected many parts of the world, including the Horn of Africa, Iran, Afghanistan, Pakistan and Turkey leading to huge agricultural losses.
“It is just a matter of time before we see another warmest year on record,” said WMO Secretary-General Prof. Petteri Taalas. “Our climate is changing before our eyes. The heat trapped by human-induced greenhouse gasses will warm the planet for many generations to come.”
