Arctic sea ice thickness and volume are decreasing too. http://psc.apl.uw.edu/research/projects/arctic-sea-ice-volume-anomaly/ http://psc.apl.uw.edu/research/p

  OK then you agree, the article was poorly written and didn't give enough information despite that info being important to making a logical argument. Also, if true, then shouldn't sea level be rising? Why aren't we hearing about that?

    > Besides shrinking in extent, the sea ice cap is also thinning and becoming more vulnerable to the action of ocean waters, winds and warmer temperatures. Did you read the article?

    Sea levels are rising and been for some time. Sea ice melt doesn't increase water levels much. This is particularly true for the arctic. Now Antarctic continental ice melt and Greenland ice melt does increase sea levels.

    Sea ice is floating. That means that it is already displacing water. When it melts, it fills the volume that it was displacing, and total sea levels remain nearly constant (the difference coming from salt concentration) Sea level rise comes from glaciers on land melting. That is also happening, but more slowly, because convection moves heat more efficiently in the ocean.

      A significant, possibly majority, of the expected sea level rise will come from thermal expansion. Melting land ice may be a minority factor. https://www.ipcc.ch/ipccreports/tar/wg1/411.htm https://www.ipcc.ch/ipccreports/tar/wg1/411.htm

    Go fill a glass of water and float some ice cubes in it. Mark the water level on the side of the glass. Watch the water level remain constant as the ice melts. Another experiment: fill a glass with water and ice so the ice isn't floating. Then watch the water level increase.
