  1. Question:
    What is to first order the process that does heat the oceans.
    Is there a nett effect of more fluxes?

      Solar radiation penetrates ocean to a few metres depth. That warms water, makes it warmer than air above. So heat seeps upward in top few metres of ocean. Radiates, evaporates & conducts heat away at surface, warming air. “greenhouse gases (GHGs)” radiate down on ocean surface, penetrating up to 1 mm. This heats top 1 mm which reduces the rate of that solar heat getting to the surface and meanwhile the wind mixes the heat downward in ocean. So some heat gets mixed downward instead of moving to surface and escaping to air. The more GHGs making more down-welling LWR the more heating of the top 1 mm, so the more solar-radiation-caused heat mixing down. That’s how it warms the ocean. All explained more thoroughly on Skeptical Science (SKS), obviously, but I like typing to keep my fingers strong & limber.

    This week I gave a Zoom talk to the Citizen’s Climate Lobby chapters of Central California. It has some very recent new studies included and emphasizes how very far we are from any sort of meaningful action, and how deeply antithetical meaningful action is to the evolutionary biological drives Nature bred into us. A few honorable and honest people, and scientists understand and would make great sacrifices to save the future. The political/economic paradigm we threw in with, will not. Nor will the large majority of us fight our short term gains in favor of long term benefit. We’ll posture, but in the end, we want someone ELSE to pay for what must be done. The proof of that is in the people we continually choose to empower. Brooks et al 2016 finds the percentage of CEO’s who fit the diagnostic criteria as psychopaths, is 21x higher than for the general population. And they are the ones we’ve let choose the people we ultimately have the choice to elect (Boss Tweed “I don’t care who does the electing, as long as I get to do the nominating”). Gilens and Page 2014 show there is zero correlation between what the average citizen prefers in legislation, and the legislation that is actually enacted, while there is near perfect correlation for the Economic Elites.

    Meanwhile, we keep trying to cheer ourselves up with hopeful little techno things here and there, which only – in the end – will help civilization grow yet faster.

    I’ve got to massage it some before the Zoom recording is ready for YouTube.

      20 thumbs up if I could.

      Most excellent. With zero sarcasm, am perpetually searching for effective ways to help, persuade, generally make a difference. Suggestions welcome.

      Very comprehensive and easy to comprehend visual aids – a lot of thought, time, blood, sweat and tears must have gone into your Zoom presentation, sure to put aside doubts in the minds of the receiver. Thanks for sharing in the “crock” blog.

    • Gingerbaker Says:

      Your presentation seems to contradict the recent statements by Mann and others who say that temperatures will start to come down very soon after we achieve near zero CO2 emissions.

      Is that a fair statement?
