How good is CO2? This good:
1. You are a carbon based life form that would not be alive were it not for carbon dioxide in the atmosphere.
2. Plant life on land and in the oceans store chemical energy through a process scientists call ‘photosynthesis’.
3. Higher amounts of available carbon dioxide result in greater plant growth, apparently both on land and in the oceans.
4. Higher amounts of available carbon dioxide result in greater crop yield.
5. Higher amounts of available carbon dioxide result in reduced land based plant water loss because of more effective respiration.
6. Phytoplankton are the base of most ocean food chains.
7. Phytoplankton are apparently growing in abundance with increased CO2.
Even this good: Professor Freeman Dyson agrees that more CO2 is good. https://www.bostonglobe.com/opinion/2015/12/03/freeman-dyson-misunderstandings-questionable-beliefs-mar-paris-climate-talks/vG3oBrbmcZlv2m22DTNjMP/story.html
“The good news is that the main effect of carbon dioxide on the ecology of the planet has nothing to do with climate. The main effect of carbon dioxide is to make the planet greener, feeding the growth of green plants of all kinds, increasing the fertility of farms and fields and forests.”
Thanks to comments on Dr Judith Curry’s site.
Proof, from co2science: The Combined Effects of CO2, Temperature and Drought on Wheat (4 December 2015)
As the air’s CO2 concentration rises in the years and decades to come, the negative impacts of drought on wheat biomass and grain yield should diminish…
