@steve_dondley @theresphysics The benefits of elevated CO2 have been settled science for >100 years. Of course, that's agronomy: a far more rigorous field than "climate science."
Scientific American called anthropogenic CO2 emissions "the precious air fertilizer" way back in 1920:

@steve_dondley @theresphysics Here's the practical effect of differing CO2 levels (among other factors). It's no laughing matter.

@steve_dondley @theresphysics Here's how elevated CO2 ("eCO2") benefits wheat:

@steve_dondley @theresphysics Here's how eCO2 benefits corn (which, significantly, is a C4 crop -- I'll leave it to you to google what that means):

@steve_dondley @theresphysics eCO2 is especially beneficial for legumes, like beans, peas, and alfalfa, which are grown for their protein content. So eCO2 helps mitigate protein shortages in poor countries. Here's a paper:

@steve_dondley @theresphysics Thousands of studies show that eCO2 is very beneficial for ALL major crops.

@steve_dondley @theresphysics eCO2 also enables plants to use water more efficiently. It does so by increasing carbon uptake relative to transpiration. In other words, when grown with higher CO2 levels, plants need less water to get the carbon they need from CO2 in the atmosphere.
@steve_dondley @theresphysics That's especially helpful in arid regions, and during droughts. Here's a paper:

@steve_dondley @theresphysics EXCERPT: "There have been many studies on the interaction of CO2 and water on plant growth. Under elevated CO2, less water is used to produce each unit of dry matter by reducing stomatal conductance."
That's settled science, yet most "climate scientists" are ignorant of it.
@steve_dondley @theresphysics CO2 emissions are benefiting whole ecosystems:
@NatGeo : "Vast swaths of North Africa are getting noticeably lusher due to warming temperatures, new satellite images show, suggesting a possible boon for people living in the driest part of the continent."

@steve_dondley @theresphysics @NatGeo Claims that CO2 is harmful are based on politics, not science.

@steve_dondley @theresphysics @NatGeo This is what mankind's CO2 emissions are doing to the planet (NASA video):
