The polar regions are some of the closest observed parts of the planet one reason being their direct impact on sea level rise. There is so much equipment trained on these areas it's insane.

This paper on very important research concluded in the Antarctic was just released "Antarctic Overturning Slowdown — Melting ice set to transform our oceans"

"This pattern of bottom water warming is already apparent in observations of change in the ocean's abyssal layers, as estimated by [Sarah Purkey] and [Dr Gregory C. Johnson] , although OBS are outpacing our model projections. So we are likely already 'mid slowdown' today."—Prof Matt England

This has massive implications for the food chain sea life above depends on and also the speed of ice melting that is already taking place.

Here is Prof Matt England's (one of the research authors) high level summary of the data:
