Are Plants Starving for Carbon Dioxide?

In a previous post I went through why I don't believe in man made global warming. Going through that exercise of examining the greenhouse gases in the atmosphere I found out that there is less than 400 ppm (0.04%) of carbon dioxide in the air, that's not much. My previous post had pointed out research that carbon dioxide levels in excess of 200 ppm have no impact on global warming but I couldn't help but wonder, are plants starving for carbon dioxide?

Plants use photosynthesis to convert carbon dioxide and water into carbohydrates like sugar for energy and wood for their structures which includes the root system. So, how do plants react to higher levels of carbon dioxide in the atmosphere?

In October, 2014, the Conversation has an article that points out that climate models are underestimating the amount of carbon dioxide that is absorbed by plants. As a result, the climate models were predicting carbon dioxide levels 16% higher than measured levels.

In November, 2016, the Christian Science Monitor published an article reporting that between 2002 and 2014 the rate of increase in the concentration of carbon dioxide was a steady 1.9 ppm/year. Prior to this, the rate of increase had been accelerating every year but now has plateaued off.

An article on The Seeker by John Dyer in July of 2017 indicates that plants are absorbing 17% more carbon dioxide than they were 30 years ago. The article goes on to talk about the forest getting thicker and the plants themselves becoming larger.

So apparently plants are starving for carbon dioxide. I know the last few years I have cut my lawn for more often than I wanted. The takeaway from this is that "climate scientist" have been underestimating the ability of plants to pull carbon dioxide out of the atmosphere and as a result have overestimated the impact of carbon dioxide on the greenhouse effect of the atmosphere.
