Yes, I thought it was a repeat as I watched it, but I still learnt from it second time round. I must have dozed off first time!

Hurricanes, Jet Streams, El Nino, QBO, SSW and Arctic sea ice all get mentioned.

Cheers, Alastair.


Not quite arctic ice, but at least no politics in this thread.
Something I learnt at a recent open day at the National Oceanography
Centre , Southampton, courtesy of one of their profs.
I'll give the answer tomorrow, allowing for a few answers here first.
A sort of thought experiment. If sufficient ice melted off , only,
Greenland to raise the average sea-level around the world by 1 metre,
how much of a rise around Greenland itself?
