4 thoughts on “Climate Sensitivity”

  1. Equilibrium climate sensitivity (ECS) is defined as the amount of temperature change in response to a doubling of atmospheric CO2 concentrations, after the climate system has reached equilibrium.

    Since CO2 is plant food, how on earth could you even theorize what an “equilibrium” would be?

    This from Quillette is related, and hilarious.

    “It’s just like my front porch at home,” he insisted. “In the afternoon the porch is much warmer than the rest of the house during the summer—you really bake in there—because of the carbon dioxide in the windows.”

    At least we’re sequestering some CO2, by injecting it into double-pane windows.

    Sure glad he’s got tenure.

  2. We’re still living in the icehouse that resulted from the Eocene-Oligocene Transition of 40 million years ago. Most theories about why it happened relate to plate tectonics, but there’s some evidence it was the result of a prolonged carbon sequestration event that took place in a landlocked Arctic Sea that resulted from prolonged and repeated overgrowth of aquatic plants that cut the atmospheric carbon dioxide in half, and that that was the proximate cause of the appearance of the Antarcic icecap. As with all such events, nobody really knows what happened, but lots of people think they do.
