Ocean Current That Keeps Europe Warm Is Weakening Because of Climate Change (washingtonpost.com)

The Washington Post: The Atlantic Ocean circulation that carries warmth into the Northern Hemisphere's high latitudes is slowing down because of climate change, a team of scientists asserted Wednesday, suggesting one of the most feared consequences is already coming to pass (Editor's note: the link may be paywalled; alternative source). The Atlantic meridional overturning circulation has declined in strength by 15 percent since the mid-20th century to a "new record low," the scientists conclude in a peer-reviewed study published in the journal Nature. That's a decrease of 3 million cubic meters of water per second, the equivalent of nearly 15 Amazon rivers.

The AMOC brings warm water from the equator up toward the Atlantic's northern reaches and cold water back down through the deep ocean. The current is partly why Western Europe enjoys temperate weather, and meteorologists are linking changes in North Atlantic Ocean temperatures to recent summer heat waves. The circulation is also critical for fisheries off the U.S. Atlantic coast, a key part of New England's economy that have seen changes in recent years, with the cod fishery collapsing as lobster populations have boomed off the Maine coast.

    Amazon sells about 30-40 million books, the Library of Congress has about that many.
    So an Amazon is roughly equal to a Library of Congress.

    and I'm getting about a foot of global warming deposited onto my driveway. Yup, this science is definitely settled.

    Well, as long as it's only a foot of global warming then there's nothing to worry your little head about.

    But if you were getting a foot of climate change that's a whole other thing. We all (well those of us with more than about two neurons to rub together and who have been paying attention) know that climate change means more extreme swings in intensity. What once would have been some late season flurries can now be <gasp> a foot of snow with an increase in intensity.

    So yeah, IMO, your foot of snow in mid-April definitely fits the Climate Change science.

    And do let us know what your particular qualifications are. I'm sure your AA from Hicks and Rubes in Flyover State Community College puts you in a unique position to play armchair meteorologist with the big boys and girls who have PhDs and publish peer reviewed research.

    Because, you know, it's Science, bitches.

    (Yeah, go ahead, mod me down; and prove I'm right.

    Global warming caused me to cheat on my wife. She understands now that I'm the real victim here.

    There is no "cooling trend". The current as it is today provides anomalously warm temperatures to northwestern Europe. If this current is fully disrupted, the UK and friends will end up having the same general climate as northern Canada. Along with northen Canada, it then will slowly warm in accordance with the generally accepted global rates.
