# The World Meteorological Organisation has warned of a 55-percent likelihood that La Niña conditions will emerge between this month and February. It refers to the large-scale cooling of the ocean surface temperatures. Secretary-general Celeste Saulo says even if a La Niña event does emerge, its short-term cooling impact will be insufficient to counterbalance the warming effect of record heat-trapping greenhouse gases in the atmosphere. The previous update, issued in September, forecast a 60-percent likelihood of La Niña in December to February.
