Cooling spell

Forecasters around the world say that a La Niña cooling of the tropical Pacific is likely to develop between August and October.

This reverse phase of the El Niño Southern Oscillation has its own set of global weather effects, but they generally are less damaging.

The developing cool strip across the tropical Pacific probably means 2017 won’t be a record warm year, but the cooling trend would only bring a temporary reprieve from global warming.
