(CNN)There is an increasing chance that annual global temperatures could exceed 1.5 degrees Celsius (2.7 degrees Fahrenheit) above pre-industrial levels over the next five years, new climate predictions from the World Meteorological Organization (WMO) say.
Global temperatures could exceed crucial 1.5 C target in the next five years
Under the 2015 Paris climate accord, countries committed to reduce their carbon output and halt global warming below 2 degrees Celsius -- and if possible, below 1.5 degrees Celsius -- by the end of the century to avoid the worst impacts of climate change.
But according to the WMO report, there is around a 20% chance that one of the next five years will be at least 1.5 degrees Celsius warmer than pre-industrial levels, with the chance "increasing with time."
Annual global temperature is likely to be at least 1 degrees Celsius warmer than pre-industrial levels, and the last five years has been the warmest on record, the assessment -- based on modeling and the expertise of climate scientists -- found.
In 2020, the Arctic is likely to have warmed by more than twice the global mean, and many parts of South America, southern Africa and Australia are likely to be dryer than in the recent past, the WMO said.
There is a 70% chance that one or more months during the next five years will be at least 1.5 degrees Celsius warmer than pre-industrial levels, the WMO assessment said.
In the coming five years, almost all regions are likely to be warmer than the recent past, scientists warned.
Over 2020-2024, eastern parts of South America are likely to be dryer, high latitude regions and the Sahel are likely to be wetter, and the northern North Atlantic region could have stronger westerly winds, which could lead to more storms in western Europe.
