    Observations? Probably coincide with the magnetic poles flipping.

    Known formally as the Atlantic Meridional Overturning Circulation (AMOC), it is the driving force which brings warm water from the Gulf of Mexico up to the UK.

    It's the basic laws of science (chemistry, optics, etc) that say CO2 causes warming, something that was recognised over 100 years ago and accept by even the most ardent climate science "sceptics" (wha

    So, as a first post, I thought I'd take a look at a graph that was posted in the IPCC thread a few times, first by @cheeky_monkey and then by @booferking. This graph is often posted by vario

    It's an interesting study, noting a long term decline that has accelerated since mid-20th century. They still think it's many more decades away from slowing to the point where it become unstable.
    The cause isn't entirely clear either (though previous related studies have suggested fresh meltwater from Greenland is a major driver), so we'll need to wait for further studies for clarification.

    I know that aerosols are considered to be bad for the environment, but as they have a colling effect, could they be used to slow down global warming?  If the various clean air acts had not been passed, would the planet be cooler today?

    Hi @Greyhound81, welcome to the forum!
    You are correct about their cooling effect, a term called global dimming. And yes, the planet would probably be a little cooler if many of the clear air acts hadn't come into play, and if coal use continued to grow. Some geoengineering proposals involve injecting aerosols into the stratosphere to reflect more sunlight too. In fact, there are plans to test this method on a small scale in Sweden soon (link below)
    However, the regional effects of geoengineering are uncertain and it couldn't prevent the other -ve effects of our CO2 emissions, such as ocean acidification. Also, as soon as you stop producing enough aerosols, warming would come roaring back!

    Swedish environmental groups warn test flight could be first step towards the adoption of a potentially “dangerous, unpredictable, and unmanageable” technology

    Bad news for the future generations in the trouser department 😄

    Penises are shrinking and genitals becoming malformed because of pollution, an environmental scientist has warned in a new book detailing the challenges facing human reproduction.
