The Science Behind the Paris Climate Accords (thebulletin.org)

Lasrick writes: The Bulletin of the Atomic Scientists offers a pretty thorough run-down of the pros and cons of the Paris climate accords. William Sweet examines not only the political machinations behind the agreement but much of what the agreement entails and how it got there after 21 years of COP meetings. "As for the tighter 1.5-degree standard, this is a complicated issue that the Paris accords fudge a bit. The difference between impacts expected from a 1.5-degree world and a 2-degree world are not trivial. The Greenland ice sheet, for example, is expected to melt in its entirely in the 2-degree scenario, while in a 1.5-degree world the odds of a complete melt are only 70 percent... But at the same time the scientific consensus is that it would be virtually impossible to meet the 1.5-degree goal because on top of the 0.8–0.9 degrees of warming that already has occurred, another half-degree is already in the pipeline, 'hidden away in the oceans,' as Schellnhuber put it." In an additional audio recording of a teleconference briefing given to the Bulletin's Science and Security Board and other leading scientists and policy makers, Sivan Kartha and Richard Somerville (both on the S & S Board) explain what was accomplished (and not accomplished).

    That's not from the 3-5 mm/year sea level rise. That's from overpumping of groundwater. Once you suck the fresh water out, the silt compacts and the land subsides. You can fairly blame that on overdevelopment, but it doesn't have the slightest connection to climate.

      So? The Bulletin of the Atomic Scientists is a global security / public policy magazine aimed at a scientific readership.

      From TFA, the reference to Kerry's speech "In the version of the speech he delivered upon arrival in Paris, he said the flat-earthers seem to think that as the world’s oceans rise, the water is just going to pour off the sides." shows the fundamental disconnect; the AGW proponents aren't willing to even consider the premises of the skeptics, so they make ad hominem attacks against the skeptics themselves to make them personally ridiculous and their positions inherently fallacial. It's always seemed to me, though, that if the proponents of one side of a scientific disagreement have to resort to bad-mouthing the proponents of the other side, rather than the research and data presented by the other side, they do it because they know that their research and data won't stand up to close scrutiny in a comparison.

    This article is a good one, anyway. It's one of the best reports of what happened at the Paris accords. It talks about the different factions (the island nation coalition, the group of 77, etc), and discusses what negotiations went on, compromises made, and how it managed to come to something that looked like an agreement.

    It has to be the deep ocean because measurements of shallow ocean temperatures have not shown any excess warming.

    What are you talking about? There has been lots of warming in the upper ocean. It is clearly shown at this NOAA page on ocean heat content.

    Since heat only moves from a warmer object to a cooler object, the heat will never exit from the ocean until the atmospheric temperature drops.

    Since over 90% of the heat energy from global warming goes into the oceans it only takes a slight change in how much goes into the ocean for major changes in atmospheric temperatures. For example 2015 is about to set a new temperature record because El Nino has reduced the amount of heat going into the ocean leaving more of it in the atmosphere.

    I doubt it was much warmer during the Holocene Thermal Optimum than it is now. Most of the science I've seen says the temperatures may have been similar.

    Silt is compacting and land subsiding in California's central valley from groundwater pumping but that isn't the case in Florida where the underlying bedrock is limestone. What groundwater pumping does in Florida is allow the ocean saltwater to intrude further inland contaminating existing freshwater supplied. Subsidence is not the issue in southern Florida.
