Any road up, here's the link:

WHY is the arctic shrinking and the antarctic growing?



It's getting warmer.



Arctic sea and land ice is melting. Any fresh water from melting land

ice is quickly lost from the area, carried south and mixed with

warmer, saline water.



Antarctic land ice is melting. Increased fresh water largely remains

within Antarctic waters, circling eastwards, making formation of sea-ice

easier.



Having just sent my previous post, I then read this about the increasing

sea ice around Antarctica:



"Factors like increasing fresh water and higher wind speeds promote ice

growth and expansion-factors that appear to be dominating right now."

So it is both fresh water and more storms that is causing the sea ice to

increase..



Cheers, Alastair.



Really?
