Global annual to decadal climate update
Odds are increasing that the annual average global temperature will rise beyond 1.5°C above pre-industrial levels, in at least one of the next five years, the UN weather agency warns in a new report. The World Meteorological Organization (WMO) said there was a 40% chance of the watershed global warming mark being met during the time frame, and these odds are increasing with time. The 1.5°C mark was established as the desirable target for all the countries of the world who signed up to the Paris Agreement to limit temperature rises, in order to prevent permanent changes that threaten the wellbeing of all life on earth. The agreement calls for limiting rises to 2°C or below. There is a 90% likelihood of at least one year between 2021-2025 becoming the warmest on record, which would dislodge 2016 from the top ranking, according to the Global Annual to Decadal Climate Update, produced by the United Kingdom’s Met Office, the WMO lead centre for such predictions.
