The likelihood that Earth briefly hits key warming threshold grows bigger and closer, UN forecasts
May 18, 2023
There's a two-out-of-three chance that the world will temporarily hit a key warming limit within the next five years, the United Nations weather agency said Wednesday.
But it likely would only be a fleeting and less worrisome flirtation with the internationally agreed upon temperature threshold. Scientists expect a temporary burst of heat from El Nino - a naturally-occurring weather phenomenon - to supercharge human-caused warming from the burning of coal, oil and gas to new heights. Temperatures are expected to then slip back down a bit.
The World Meteorological Organization forecasts a 66% likelihood that between now and 2027, the globe will have a year that averages 1.5 degrees Celsius (2.7 degrees Fahrenheit) warmer than the mid 19th century.
