Interesting site about C02.
Strong group of members.

What about all those dogs in the urban areas?
Will those poor people have to watch their dogs die a terrible excess Co2 death?

It appears that agstar isn't going to respond, so I will generously help him out.
CO2 is immediately fatal at 10% concentration. That would be 100,000 ppm.
That is a mere 240 times higher than the current 420 ppm concentration.
What do you think agstar, do we have enough fossil fuels to accomplish that?

The flat earth climate change deniers will, so it seems, never accept the science that proves CO2 from burning fossil fuels causes climate change.
They will resort to all kinds of dumbass ideas in their denial.
Like A5 they disregard the all the signs of climate change and serious consequences and focus on the very small benefits of increased plant growth that will be offset by higher temperatures and increased frequent drought and heat stress in southern Alberta.
We all know CO2 levels are not a limiting factor in crop production in the southern prairies. The limiting factor is moisture.

The CO2 fertilization effect has been dominant driver of the global-scale increase in “leaf area index” (LAI), or greening, since the 1980s. Scientists have estimated that CO2’s photosynthesis-enhancing capacity is 70% responsible for the greening trend (Zhu et al., 2016 ([url]https://www.nature.com/articles/nclimate3004[/url])).
....
Using much more reliable MODIS data, scientists (Chen et al., 2024 ([url]https://www.sciencedirect.com/science/article/pii/S2351989423004262[/url])) can now say the LAI trend in the 21st century is robustly positive, and that 2001-2020 “global greening is an indisputable fact.”
The satellite data indicate 55.15% of global areas are greening “at an accelerated rate,” whereas just 7.28% have undergone a browning trend since 2001.
CO2 fertilization is still the dominant (75.63%) driver of Earth’s 21st century greening trend. Any drought trends in recent decades cannot overtake the positive CO2 fertilization effect, as all drought can do is slightly slow down the acceleration of the CO2-induced greening trend.
