so lazy

It’s summertime ofcourse the ice will melt in summer, but it ALWAYS goes back to normal in winter and infact, as the graph shows sea ice in winter is actually growing not melting.

I passed your inquiry along to some of my colleagues. Here are their answers:

From Walt Meier at NSIDC:
There are potential links between the Arctic and other regions, but these are mostly limited to the mid-latitudes and perhaps the northern subtropics. Any links beyond that would be tenuous.

From Ted Scambos at NSIDC:
In general, there’s not much climate communication between the hemispheres except in terms of global trends. Arctic sea ice decline is unlikely to have much of a direct impact on Botswana. The ENSO pattern and related patterns in the Indian Ocean are probably more important to this trend in South Africa. I’m sorry we can’t help more.
