Antarctica Gains More Sea Ice this Year
At the North Pole we are losing sea ice cover, year on year and we can tell this from satellite mapping. Using the same techniques we find that at the South Pole the sea ice cover is now at its greatest extent for thirty years. The sea ice was in 2012 very slightly higher than the extent previously recorded which was in 2006. Ice lose at the North Pole is far greater than ice gain at the South, but nevertheless the findings are puzzling.
One year of record sea ice extent in the Antarctic does not win or lose the global warming argument any more than one year of the opposite phenomena does at the Arctic. They should be considered carefully as part of the overall understanding of what is happening to our climate. There is a message from the south indicating that that part of the world is getting very slightly colder, for this year, while from the North the message claims that that part of the world is getting very much warmer.
Both can be evidence of global warming, as heat moves from warmer places to colder places carried in the molecules of air and water as those molecules vibrate and oscillate around the global carrying heat spreading and diluting it.
