Recent satellite data show the Arctic sea ice has recovered from recent lows. Data from the European space Agency Cryosat-2 satellite indicates at 10 200 cubic kilometres Arctic sea ice volumes in 2014 were above the average over the past five years and sharply above the lows of 4275 cubic kilometres in 2011 and 6000 cubic kilometres in 2012. Oceanographers at Woods Hole Oceanographic Institution sent a under water robot deep into the Antarctic sea to measure the ice and have found that the ice is much thicker than has been predicted over the past 20 years. The melting of the small peninsular of the west antarctic ice sheet is due to a underwater volcano.
Nasa scientists have found that after years of research they have gathered data showing that normal, decade long changes in Arctic Ocean currents driven by a circulation known as the Arctic Oscillation was largely responsible for the major Arctic climate shifts observed over the past several years. These periodic reversals in the ocean currents move warmer and cooler water around to new places, greatly affecting the climate. The AO was at record low last winter explaining the record cold and snow in middle latitudes. A strongly negative AO pushes the coldest air well south while temperatures in the polar regions are warmer than normal under blocking high pressure. It may have been this AO that sunk the Titanic with icebergs much further south than was expected by the Titanic on its voyage.
Tthe IPCC climate models are only computer projections which have been repeatedly shown to be wrong. their predictions of ocean warming has not been borne out by direct observations. Ocean temperatures have been only properly measured since 2003 using the Argo system. In the Argo system a buoy duck dives down to 2000m, slowly ascends and reads the temperatures on the way, then radios the result back by satellite to HQ. Three thousand ARGO buoys patrol the oceans constantly. Their readings show that the ocean temperature since 2003 has been basically flat. Reality is very different to the climate models.
