NASA: Sea levels falling

Sea level rise is caused primarily by two factors related to global warming: the added water from melting ice sheets and glaciers and the expansion of sea water as it warms. 

So, as sea level has been falling for the last two years, does that imply the reverse?  Do we have global cooling adding ice to ice sheets and cooling oceans?

H/t Ice Age Now


  1. A bit premature to tell yet, but good to know. Greenland and the Arctic ice recoveries are other indicators of maybe we are going back into a cooler period. Then there is the low Sun activity. But, wouldn't we be better off in a warmer and greener world.

  2. Sea Level increases due to thermal expansion. IR radiation between 13 and 18 microns doesn't warm water, visible radiation does. Warming oceans are the result of more visible radiation reaching the oceans. Unless CO2 causes more visible radiation to reach the oceans, then there isn't much of a case to blame CO2. Warming oceans are evidence of more warming visible radiation reaching the surface, which would also explain why the atmosphere is warming. Explain why the oceans are warming and you explain why the atmosphere is warming, and it isn't CO2 and IR radiation, it is visible radiation.
