1.5 C. Warming Could Be In Next 5 Years – WMO
New climate predictions increase likelihood of temporarily reaching 1.5 °C in next 5 years
27 May 2021 (World Meteorological Organization)
“There is about a 40% chance of the annual average global temperature temporarily reaching 1.5°C above the pre-industrial level in at least one of the next five years – and these odds are increasing with time, according to a new climate update issued by the World Meteorological Organization (WMO)…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…Over 2021-2025, high-latitude regions and the Sahel are likely to be wetter and there is an increased chance of more tropical cyclones in the Atlantic compared to the recent past (defined as the 1981-2010 average)…
In 2020 – one of the three warmest years on record – the global average temperature was 1.2 °C above the pre-industrial baseline…[There is an acceleration of] climate change indicators like rising sea levels, melting sea ice, and extreme weather, as well as worsening impacts on socio-economic development…The chance of temporarily reaching 1.5°C has roughly doubled compared to last year’s predictions. This is mainly due to using an improved temperature dataset to estimate the baseline rather than sudden changes in climate indicators. It is very unlikely (10%) that the 5 year mean annual global temperature for the entire 2021-2025 period will be 1.5°C warmer than preindustrial levels…The development of near-term prediction capability was driven by the WMO co-sponsored World Climate Research Programme, which declared one of its overarching Grand Challenges is to support research and development to improve multi-year to decadal climate predictions and their utility to decision makers…” click here for more
