100% nonsense. It amazes me that even the smartest climate activists are uniformly ignorant of agronomy!
Of course most crops are C3 & eCO2 is hugely beneficial for them. But C4 crops also benefit greatly from eCO2.
EXCERPT:
"There have been many studies on the interaction of CO2 and water on plant growth. Under elevated CO2, less water is used to produce each unit of dry matter by reducing stomatal conductance."
@ciais_philippe 2/7❯ The benefits of rising CO2 levels for agriculture are spectacular. CO2 is not the only reason for improving crop yields, but it is one of the major reasons:
@ciais_philippe 3/7❯ The best scientific evidence shows that CO2 emissions are beneficial, and manmade climate change is modest and benign. Here are some relevant studies: sealevel.info/negative_socia…
@AkademiskC 2/7》Here's the Most Trusted Man in America™ (Walter Cronkite) reporting on the threat of Global Cooling, 9/11/1972:
Prof. Hubert Lamb (the source who Cronkite cited) was founding director of the UEA Climate Research Unit.
@AkademiskC 3/7》Here's a 1974 CIA report about the looming threat of a return to the neo-boreal conditions of the Little Ice Age (global cooling). It summarized the scientific consensus:
2/17. That DeSmogBlog article about Will Happer is a brazen, despicable smear.
DeSmogBlog claimed that "Peabody Energy paid [Happer] $8,000 which was routed through the CO2 Coalition."
That's a LIE. Prof. Happer was not paid, because he asked that his entire fee be donated to charity.
3/17. DeSmog also falsely claimed, "Happer told Greenpeace reporters that he would be willing to produce research promoting the benefits of carbon dioxide for $250 per hour, while the funding sources could be similarly concealed by routing them through the CO2 Coalition."
That's ANOTHER LIE.
Happer did no such thing. Rather, he was asked to produce a white paper (which is not "research") explaining the best scientific evidence about the costs and benefits of fossil fuel use—and he generously asked that the fee for that work be donated to charity.
The CO2 Coalition @CO2Coalition is a 501(c)(3) educational charity. Happer didn't "route" anything "through" them. He very generously donated the fees to which he was entitled, to that very worthy charity.
I have the paper, and the five responses, and Skrable's responses to the responses, on my site, here: sealevel.info/Skrable2022/
2/6. The 14C bomb spike decay reflects 3 main processes:
1. Removal of CO2 from the air, into other "reservoirs" (ocean & terrestrial biosphere).
2. Exchanges of carbon between atmosphere & other reservoirs.
3. "Suess effect" dilution: the addition of fossil CO2 with no 14C.
3/6. The bomb spike decay follows a beautiful logarithmic decay curve, with an 11 year half-life, so an 11 / ln(2) = 16 year apparent lifetime. But that fails to take into account Suess effect dilution. sealevel.info/logc14_two_hal…
