Plants the world over are absorbing about 31% more carbon dioxide than previously thought.
Cornell University & Oak Ridge National Laboratory used new models and measurements to assess GPP (Gross Primary Production) from the land at 157 petagrams of carbon per year, up from an estimate of 120 petagrams established 40 years ago and currently used in most estimates of Earth’s carbon cycle.

Press release: Plant CO2 uptake rises by nearly one third in new global estimates https://www.ornl.gov/news/plant-co2-uptake-rises-nearly-one-third-new-global-estimates
I have questions: If we increase CO2 but available nutrients stay the same, how it affects plants and herbivores?
Is the situation analogous to humans who eat too much carbs but don't get enough nutrients? Less nutrients per kg? Does vulnerability to plant diseases increase?
