Part of the problem is some climate change deniers openly accept that having more CO2 will heat the earth but also say that having more CO2 in the air will "gre

  Sure. As if CO2 were the limiting factor in photosynthesis, which it isn't. But that's OK, because they don't really care about being right. They'll just shift on to the next argument, even if it's contradictory to the ones they're already using. That's how a Gish Gallop works. You can just point them at https://skepticalscience.com/oneliners.php https://skepticalscience.com/oneliners.php for a lengthy list of the arguments they're going to use and the trivial reasons why they're wrong, but it doesn't get at the core of the problem: you can't reason somebody out of a place they didn't reason themselves into.

    But increased CO2 is strongly linked to the greening effect. >Studies have shown that increased concentrations of carbon dioxide increase photosynthesis, spurring plant growth. >Results showed that carbon dioxide fertilization explains 70 percent of the greening effect, said co-author Ranga Myneni, a professor in the Department of Earth and Environment at Boston University. “The second most important driver is nitrogen, at 9 percent. So we see what an outsized role CO2 plays in this process.” https://climate.nasa.gov/news/2436/co2-is-making-earth-greenerfor-now/ https://climate.nasa.gov/news/2436/co2-is-making-earth-green...
