The surfaces of the oceans went through a short period of rapid temperature change 40 years ago, scientists have found - but the cause is unknown.
Top layers of Northern Hemisphere water cooled by about 0.3C; the south saw roughly the same degree of warming.
Writing in the journal Nature, the team suggests that air pollution cannot be responsible for the changes, as has been suggested for mid-century cooling.
They do not suggest a cause. It is not clear what could link all the oceans.
However, events called Great Salinity Anomalies have been recorded in the last few decades in the North Atlantic Ocean - including one around 1970.
The 1970s global temperature record shows a period where the Earth's surface cooled in the Northern Hemisphere, while the Southern Hemisphere saw warming.

“The 1970s global temperature record shows a period where the Earth’s surface cooled in the Northern Hemisphere, while the Southern Hemisphere saw warming.”
There you go! Cold travels north. Mystery solved.
Hmm... scientists don’t know why.....
Maybe they're hedging their position on either saving their tattering reputation as Scientists, or are holding out for the highest bidder of grant money. Or maybe both.
I’m thinking huge amounts of grant money with a touch of cowardly lying.

Could it be the *Sun*, the Earth's sole source of heat?
