This report from the World Meteorological Organization (WMO) reveals that there is a two-out-of-three chance that the world will temporarily reach the internationally accepted global temperature threshold for limiting the worst effects of climate change within the next five years. This threshold was set by the 2015 Paris climate agreement, and is likely to be surpassed due to a combination of human-caused warming and a natural El Nino climate pattern. The WMO has urged countries to take action to reduce their emissions and to prepare for the impacts of climate change.
