Global warming campaigners aren’t very good at being green.

There’s their bird and bat chopping wind turbines, lifeless fields covered over by solar panel silicone, and generating electricity by grinding trees into pellets and burning them as “renewable” biomass.

Then there’s their demonization of CO2, the gas you just exhaled.

CO2 is the gas of life.  Plants are green because they use chlorophyll to convert CO2 and water into glucose and oxygen.  That’s where food comes from.

CFACT senior policy analyst Bonner Cohen posted a thoughtful meditation on the benefits of CO2 at

What if manmade CO2 isn’t the villain deep-thinking elites say it is? What if rising levels of atmospheric CO2 are instead fighting the scourge of malnutrition in the world’s poorest regions? A new White Paper, “What Rising CO2 Means for Global Food Security,” published by the CO2 Coalition points out that global food security is one of the most pressing problems facing the planet’s growing population…

The White Paper acknowledges that the clear benefits to humanity of industrial CO2 as a byproduct of the use of fossil fuels must be weighed against predictions, generated by computer models, of CO2-driven warming leading to climate catastrophes. Citing research from climatologist Judith Curry and environmental studies scholar Roger Pielke Jr., the study notes that “the modest one-degree Celsius rise in average temperatures since 1900 due to what all models acknowledge is a mixture of natural and industrial causes, has had a negligible effect to date on variables such as the rate of the rise of sea levels and the frequency of droughts and hurricanes.”

Climate computer models have always run too hot.  They over-estimate temperature sensitivity to atmospheric CO2.

There’s nothing virtual about the benefits of CO2.  It’s the gas that feeds us.  We’re made from it.
