CO2 is Plant Food – We Need More!

Will more CO2 bring more abundant crops? A common assertion in the climate change disinformation campaignCO2 is plant food, therefore more of it is a good thing

Or so goes a common tenet of the climate change disinformation campaign. Similar to the Glenn Beckian idea that “the government wants to tax your breathing,” the notion is based on a poorly understood (or deliberately misrepresented) concept in an effort to twist the truth, sowing doubt and confusion.

Plants eat CO2 – so the more of it there is in the atmosphere, the better off we all are – right?

No – as common sense might suggest.


Like Beck’s hyperbolic confusion about the difference between the source of biologically respirated CO2 and coal plant emissions, many, such as the fantastical “Lord” Christopher Monckton, employ similar tactics with their simplistic – and dangerous – “CO2 is plant food” argument. They advocate as good policy maintaining, even increasing, the continued disruption of the natural carbon cycle upon which the entire history of agriculture is based.

Greenman3610 (Peter Sinclair ) takes a look at the issue in his latest “Climate Crock of the Week” video.

  1. Disturbing post about how science is being bought by industry and then totally corrupted.

    Such arguments annoy me so much because we are wasting our time responding

    We are really getting into the last years where we still have a chance to stop climate change.

  2. So, some people wish to "stop Climate Change".
    Be careful of what you wish… for it may come true.
    During the entire existence of Earth, the climate has changed… when that stops so will Earth.

    • Thanks for the comment Ronnie. I agree with your point and there is no dispute of naturally occurring climate change anywhere in this blog, nor by any climate scientist, nor by anyone with the least bit of understanding of the issue.

      • Hej Tom,
        yes, natural climate change is an accepted fact. I appreciate your moderate response.
        As for CO2… it seems to me that Earth's atmosphere is currently much closer to dangerously low levels than it is to a dangerously high levels.

        An atmosphere containing less than 150ppm of CO2 would likely cause adverse effects on both plant and animal life.
        Contrast that with CO2 at 1100 ppm…
        Most (if not all)) independent experiments show a positive impact an plant life.
        Is there evidence that 1100ppm is a threat to animal life? It seems to me that a reasonable upper limit of safe CO2 in the atmosphere is somewhere above the upper figure I mention.

        If these assumptions are acceptable to you, Tom, than I submit that at current levels, 390ppm is much closer to the dangerously low limit of <150ppm than it is to the dangerously high level of >1100ppm.

        Climate Change is a fact.
        Global Warming is a fact.
        And I do believe that CO2 is the first link in the food chain.
