“Summary
Atmospheric carbon dioxide concentration ([CO2]) is increasing, which increases leaf-scale photosynthesis and intrinsic water-use efficiency. These direct responses have the potential to increase plant growth, vegetation biomass, and soil organic matter; transferring carbon from the atmosphere into terrestrial ecosystems (a carbon sink). A substantial global terrestrial carbon sink would slow the rate of [CO2] increase and thus climate change. However, ecosystem CO2 responses are complex or confounded by concurrent changes in multiple agents of global change and evidence for a [CO2]-driven terrestrial carbon sink can appear contradictory. Here we synthesize theory and broad, multidisciplinary evidence for the effects of increasing [CO2] (iCO2) on the global terrestrial carbon sink. Evidence suggests a substantial increase in global photosynthesis since pre-industrial times. Established theory, supported by experiments, indicates that iCO2 is likely responsible for about half of the increase. Global carbon budgeting, atmospheric data, and forest inventories indicate a historical carbon sink, and these apparent iCO2 responses are high in comparison to experiments and predictions from theory. Plant mortality and soil carbon iCO2 responses are highly uncertain. In conclusion, a range of evidence supports a positive terrestrial carbon sink in response to iCO2, albeit with uncertain magnitude and strong suggestion of a role for additional agents of global change.

Carbon dioxide is not the story we are told it is. Right now it is justification for penning humans for their carbon footprint. If they want to count us. Then Stand up and be counted.
Evil bastards (not the authors, the WEF, Bill Gates, etc). Whatever they tell you to do, just do the opposite. God, Mother Nature, the plants, the animals that eat the plants, the birds that are not chopped up by the windmills, the birds that are not cooked by the solar panels, your children and their friends, the people in the 3rd world who would be pressed into mining lithium, the residents of the 3rd world that make many of the products that we use, and depend upon the petroleum based energy sources (ultimately all the energy sources that we use beyond a camp fire) will thank you.
And you will live a freer happier and longer life.
On a side note and truly related to the scheme, I am truly amazed at how Agenda 21, Agenda 2030 and Agenda 2050 has creeped to the curriculum in Ontario and all across Canada. I am amazed at how the United Nations has influenced children and possibly their parents through ideas that are being placed in the Ontario curriculum.
I am a graduate of the University of Western Ontario. I have noticed over time, that the United Nations also influences what students are being taught.
