CO2 and plants

New study undercuts favorite climate myth ‘more CO2 is good for plants’

A 16-year study found that we’re at a point where more CO2 won’t keep increasing plant production, but higher temperatures will decrease it.

A new study by scientists at Stanford University, published in the Proceedings of the National Academy of Sciences, tested whether hotter temperatures and higher carbon dioxide levels that we’ll see post-2050 will benefit the kinds of plants that live in California grasslands. They found that carbon dioxide at higher levels than today (400 ppm) did not significantly change plant growth, while higher temperatures had a negative effect.
