The video argues that rising CO2 levels both directly stimulate plant growth and, as a result of their warming properties, cause winter temperatures to rise, thereby indirectly stimulating plant growth

I remember a 1990s oil company propaganda film called “The Greening of Planet Earth” that argued we didn’t need to worry about increases in CO2 because plants would just be that much happier and gobble up the carbon.
That plants do better with more CO2 is no surprise, but it’s still good to see more plant growth. The question is whether plant growth will fully offset the excess of CO2 in the atmosphere (since CO2 levels are rising, the answer seems to be no).
And even if plants could do it all, would there be other negative effects? That too seems to not look good, as I’ve read that food plants have become less nutritious as they grow more quickly as CO2 increases.
Good news, but we’re still in a fine mess.
Some other industry players also made a movie about climate change at about the same time, but their conclusion was basically, "Don't worry about it, because plants will just love all the excess CO2." I remember this film because of an otherwise good, but somewhat dogmatic conservative high school physics teacher.
