Sea Level in the Arctic is Falling

This is just one of dozens of responses to common climate change denial arguments, which can all be found at How to Talk to a Climate Sceptic.


Objection:

According to the latest state of the art satellite measurements from over the Arctic, sea levels are falling! Guess all that ice isn’t melting after all.

Answer:

Yes, a new study using Europe’s Space Agency’s ERS-2 satellite has determined that over the last ten years, sea level in the Arctic ocean has been falling at an average rate of around 2mm/year. This is very new and very interesting news, though it is preliminary and not published in any peer reviewed journals yet. But even if these results hold up to time and scrutiny, it is not evidence that globally sea levels are not rising, because they are.

Sea level and sea level change, is not uniform around the globe.

Local sea levels are subject to many influences including: wind and ocean currents that can "pile up" the ocean water locally, temperature anomalies like El Nino, local gravity wells of ice sheets and land masses and regional salinity levels that alter the water’s density. Measurement of these levels is further complicated by changes in land height as the Earth’s crust moves up or down from tectonic motion and rebounding after long and recently ended glaciation, although these complications are avoided by using satellite measurements.

So in short, this is undoubtedly of interest to specialists in several fields, but it does not in any way alter the Global Climate Change picture.

  1. crakar I see no need for further discussion on this point or any other you’ve run away from. I merely raised it as an example.

    Your complaint on the other thread (“Now you see Chris your post above puts you in the category as [sic] Skip and WOW. No substance in your post just personal attacks, in other words rubbish. So why dont you jump right back into the box you crawled out of………theres a good boy.”) looks rather hollow when your reaction to posts of any substance at all is as pathetic as above.

    This was just the first example I found, if you want further examples of your lack of appreciation of posts with substance just ask.

    “I suggest the next time you feel our conversations have been prematurely cut short you raise it with me a little quicker”

    No, I’ll just assume that because you made no comment then you must agree…
