So, we’re told the globe is warming. We’re told the surface temperatures are warming, and we’re told the oceans are warming. If both are true, then how is this possible?
Well, it isn’t possible. Ocean currents and the physical properties of heat simply don’t allow for these two things to be congruently true.
You have both deep water and near surface currents circumpassing the Antarctic (where all of the SH sea ice is).
