The Pacific Ocean may open a “heat vent” above it that releases enough energy into space to reduce projected climate warming caused by the build-up of greenhouse gases in the atmosphere.
High clouds over the western tropical Pacific Ocean seem to decrease when sea surface temperatures are higher, said Arthur Hou of the American space agency, Nasa.
The mechanism allows the heat to escape, keeping the oceans cool.
The newly discovered vent, if confirmed, could significantly reduce estimates of future global warming now being put forward by computer models of the Earth’s climate.
