Over the past three decades, our planet has gotten greener!
Even stranger, the greening of the planet in recent decades appears to be happening because of, not despite, our reliance on fossil fuels.
While environmentalists often talk about how bad stuff like CO2 causes bad things to happen like global warming, it turns out that the plants aren't complaining.

      50 x 50 Pixel The giver of life
This is a short description of the process of photosynthesis and how the carbon dioxide molecule gives us life as well as heat
Photosynthese - Strahlung
      701 x 480 Pixel

The graphs show how the rate of photosynthesis varies with irradiance, the three experiments differing only in the concentration of CO2.

The lowest graph is that for a CO2 concentration of 0.03%, much as it is at this time [actually ~385 ppmv or 0.0385%].

In the early part of the graph the rate of the reaction is related almost directly to the amount of irradiance, but the rate falls off at higher irradiances and eventually levels off.

This tells us that at higher irradiances it is the concentration of CO2 that limits the reaction rate, there is sufficient light falling on the leaves, but the requirement for more CO2 is the limiting factor.

We strongly object to CO2 being regarded as a pollutant; it is the giver of life and we all depend upon its chemical and radiative properties.
