    If climate change wrecks your city, can it sue Exxon?
    Scientists can now link disasters to climate change, opening the door to lawsuits against fossil fuel companies

    Research hints at tipping point in the Atlantic’s currents
    Lots of fresh water from melting ice could radically alter the Atlantic’s currents.
    ...
    The key issue in all of this is the density of water, which drives the cycling of the oceans. Given similar temperatures, salt water is more dense; given similar salt content, cold water will be more dense. These density differences are large enough that if you have a patch of warm, fresh water sitting on top of cold, salty water, the two bodies won't mix very efficiently. The water ends up layered, or stratified.

    This sort of stratification hasn't happened in the North Atlantic. The surface water that arrives north is warm but salty, and the Arctic winter allows it to cool and mix with the layers below it. That's enough to cause the water to sink and drive the cycling.

    But the researchers—Marilena Oltmanns, Johannes Karstensen, and Jürgen Fischer from the GEOMAR Helmholtz Centre for Ocean Research—focus on an area where that is changing: the Greenland coast. Specifically, they look at the Labrador Sea, between Canada and southern Greenland, and the Irminger Sea, between Greenland and Iceland. And here they find something unusual. "Neither cold-and-fresh polar water nor warm-and-salty Atlantic water matches the hydrographic properties of the surface water in these regions—being warm and fresh," they write. "We speculate that it has a continental origin and was modified by surface heating."

    In other words, the water is fresh because it comes from the melting of Greenland and warm because the temperatures at these locations have been driven upward by climate change.

    Boas!

    Chevron’s lawyer, speaking for major oil companies, says climate change is real and it’s your fault
    In a court hearing in San Francisco, oil companies publicly backed the science of climate change

    In a federal court in San Francisco on Wednesday, major oil companies concurred with the “scientific consensus,” saying it was “extremely likely” that human activity has been driving global warming since the middle of the 20th century. They just don’t think they can be sued for it.
