I’ve read articles saying that more CO2 is not necessarily a bad thing because it’s caused more plant growth due to better temperatures. Anyone ever see any articles like that?
Plants grow better with more CO2 up to a point, around 800-1000 ppm depending on the plant.
But that is in a greenhouse with unlimited nutrients. In nature nitrogen, phosphorous, potassium are limiting factors, or just growing in a place without enough water or light. This is why plants haven't evolved better respiration, because CO2 is usually not the limiting factor.
This is why plants in nature won't just soak up the excess CO2, and also why iron seeding the oceans works so well; the oceans have tons on nutrients for photosynthesis except for iron. So you add some iron and you get a huge bloom that soaks up CO2 and then the algae falls to the sea floor.
Thanks. I do feel like the climate hysteria makes it impossible to have honest discussions
It's hard to get to the truth because there's irrational hysteria on both sides.
A lot of the arguments against the warming are 'flat earth' where they grasp at straws to justify their belief, and they sound reasonable to a layman except with flat earth you can look at pictures of the earth and see it's nonsense. On the other hand, climate scientists seem to be in a Covid-like 10x worse than it is hysteria where they'll get fired and lose their funding for questioning the party line and then media hypes that into 100x worse.
Personally I judge these things by comparing risk. The scientists and people in charge clearly do not believe it's a major problem or they'd be strongly behind using geoengineering to control climate. There are known methods that quickly extract massive amounts of CO2 (like iron seeding), simulate volcanoes, and so on but each with some seemingly small risk to them.
So these people who study climate as their day job believe the risk from growing CO2 is less than the risk of these geoengineering solutions.
Also I remember someone saying that if they were truly sincere they would promote nuclear power.
