Gambling on the Gulf Stream

British Pathé News was a British institution that produced news reels and documentaries from 1910 to 1970. Their website is full of news clips of polar interest such as Shackleton’s death in 1922.

But here is something wonderful and obscure. Gambling with the Gulf Stream made in 1936!

In just 2 and a half minutes the voice-over explains what the Gulf Stream is, how much heat it carries (“every day it gives more heat than the world’s coal supply in 2 years“), and what would be the impact on some regional climates if its pathway was deliberately moved by geoengineering.

“We should find icebergs off our favourite seafront”

“instead of icefields tropical plants would spring up"

It’s brilliant and shows our 1936 understanding of the effect of the oceans' circulation on regional climate.

 

Today we have a better understanding of the ocean circulation at a climate scale. But naturally we still have much to learn. Quirin Schiermeier published a nice piece in 2013 Nature, Oceans Under Surveillance, which showed the big experiments intended and currently going on.

Since the piece was written the OSNAP program (Overturning in the Subpolar North Atlantic Program) began, and RAPID –WATCH is still running. Both projects have some great information on their websites and there are active researchers on twitter.
