    ROTFLMAO!

    Another fake ‘owning the libs’ article. There is a fantasy that those who love low operating expense are ‘green idiots’ who can be fooled so easily.

    That is an answerable question @bisco. You observe X species of hummingbirds and each species has a current range. Overlay those ranges with climate maps. Next comes future climate projections. When your future climate falls outside some species' range, it will likely have moved away.
    There are many ornithologists who ought to be doing such things, so you're off the hook. But they aren't.

    The high-elevation limitation is a different matter, and won't play out in coastal backyards. I don't recall seeing zumbadores in White Mtns of NH, but yes in Smokies down south. There, they could possibly run out of resources. Also I have a very sad story about Smokies hummingbirds. Maybe I should have a subscription website for all this stuff eh? Instead of giving it away for free here.

    It's not really 'news' but:

    Earth Hits Record Carbon Dioxide Levels

    Annual maximum is in May with annual minimum in Sept (or Oct). It has been this way since Keeling started this measurement campaign in 1958, and was most likely so for 100 years before. Annual averages increase each year as well, and will continue to do so until emissions are substantially curtailed.

    So it's not news, and will be viewed by some as clickbait. OTOH, If there were not media reports like this after every May, some people would think increases were finished. Maybe? I'm not sure.

    But it seems worth knowing what the patterns are, and reasons why, even if people don't get lathered up about possible/probable implications.

    In the version I heard yesterday, the focus was that at 421 ppm, it has broken through a milestone of 50% increase from the pre-Industrial level of 280 ppm.

    I think late pre-industrial 280 ppm is probably pretty close. As backward-looking techniques are unlikely to improve further, pin it there OK.

    280 times 1.5 is 420 - no argument there :) However ...

    We ought not be comparing to the known-highest month of May. At Scripps site (I just updated my copy of their Mauna Loa data), most recent 12-month average is 417.2 ppm. Most recent 5-year average is 412.2 ppm.

    Not advocating which 'window' is most appropriate for such a comparison, but the highest month would not be my first choice.

    Mauna Loa is appropriate for extrapolation though (not all records are), so I'm happy to predict that 12-month running avg CO2 will reach 420 ppm in 2023 August. Will throw confetti then.

    That gives me time to think of something other than confetti to throw.

    =================

    Looking at currently monthly data, it appears that the trailing 12-month average is 416.97 ppm.

    Keeling's data starts in March 1958, but several months were missed. The first 12-month average can start in Oct 1958, and figures as 315.78 ppm. We have now gone up just over 100 ppm since he started.

    Source: When Trump’s EPA Needed a Climate Scientist, They Called on John Christy - Inside Climate News

    . . . In an analysis he put together for the Environmental Protection Agency’s elite board of outside science advisors, of which he was a member, Christy argued that Earth’s climate simply wasn’t that sensitive to changes in carbon dioxide. So neither the weakened federal standards, nor California’s tougher standards, which the Administration repealed as part of its rollback, would make any difference.

    “My analysis showed that it doesn’t make a difference which rule you pick,” Christy, a professor and interim dean of the College of Science at the University of Alabama in Huntsville, said in an interview. “You can have the California rule for the whole country or California accept the rest of the country’s rule and the amount of carbon emissions are so tiny relative to the world, it’s not going to make a difference in whatever the climate is going to do.”

    It’s an assertion that flies in the face of mainstream science. But it is right in line with the argument that Christy has been making for 30 years, drawing on his pioneering—but hotly disputed—work on satellite temperature readings. He has argued before Congress and elsewhere that the Earth is not heating as quickly as climate models predict, and that society should not make the costly decision to curb fossil fuel consumption based on what he often describes as the “murky” science of climate change.
    . . .     ​

    Not surprising.

    Here is some mainstream news publicity on this practice. While there are a couple old stand-alone threads for this topic, I'll tack this onto the most recent mention here.

    Seattle TImes: Meet the peecyclers. Their idea to help farmers is No. 1
    (originally from NYTimes: Meet the Peecyclers. Their Idea to Help Farmers Is No. 1. - The New York Times)
