|Motto||"Carbon Dioxide is Essential for Life"|
|Founder(s)||Roger Cohen, William Happer, Rodney W. Nichols|
The CO2 Coalition is a nonprofit climate change denial advocacy organization in the United States founded in 2015. The group's claims are disputed by the vast majority of climate scientists. The organization has 55 members. The organization been funded by energy industry firms and conservative activists who oppose climate change mitigation policies, such as the Mercer Family Foundation and Koch brothers. It is viewed as the successor to the George C. Marshall Institute.
The CO2 Coalition was one of over 40 organizations to sign a letter dated May 8, 2017, to president Donald Trump thanking him for his campaign promise to withdraw from the Paris Agreement, an action Trump announced 3 weeks later on June 1, 2017.
There is limited evidence to suggest that an increase in carbon dioxide would be beneficial for plant growth, in the long term. Carbon dioxide is rarely the limiting factor for natural plant growth.
The consensus that humans are causing recent global warming is shared by 90–100% of publishing climate scientists according to six independent studies by co-authors of a 2016 paper. Those results are consistent with the 97% consensus reported by Cook et al (Environ. Res. Lett. 8 024024) based on 11 944 abstracts of research papers, of which 4014 took a position on the cause of recent global warming. A survey of authors of those papers (N = 2412 papers) also supported a 97% consensus.
Climate change is likely to stimulate the development of harmful cyanobacterial blooms in eutrophic waters, with negative consequences for water quality of many lakes, reservoirs and brackish ecosystems across the globe.
Air pollution needs to be addressed as visible threat. A total of 54 000 and 27 500 premature deaths can be avoided by a 20% reduction of global anthropogenic emissions in Europe and the US, respectively (The article subsumizes the surface concentrations of O3, CO, SO2 and PM2.5 in their so labeled "Economic Valuation of Air Pollution-index") . A 20% reduction of North American anthropogenic emissions avoids a total of ∼ 1000 premature deaths in Europe and 25 000 total premature deaths in the US. A 20% decrease of anthropogenic emissions within the European source region avoids a total of 47 000 premature deaths in Europe. Reducing the east Asian anthropogenic emissions by 20% avoids ∼ 2000 total premature deaths in the US. These results show that the domestic anthropogenic emissions make the largest impacts on premature deaths on a continental scale, while foreign sources make a minor contribution to adverse impacts of air pollution. However, the results of the study are not based on CO2 emissions. 
Air pollution already costs a lot. In the entire Medicare population, there was significant evidence of adverse effects related to exposure to PM2.5 and ozone at concentrations below current national standards. This effect was most pronounced among self-identified racial minorities and people with low income. (Supported by the Health Effects Institute and others.)
Generally, global past and planned land usage of the Earth is not with the view of helping plants grow. Much of the Earth's biodiversity is facing extinction due to human activity all while CO
2 has been rising.
