Agree up to "the whole planet has got a lot greener because of 150 years of carbon fuel use"
Gonna have to pull you up short there. :)
Higher CO2 doesn't benefit all plants, which creates unpredictability. We can adapt, but quick changes in nature translate to dodgier food supply chains.
CO2 may have greened parts of the planet but the same carbon fuels are powering the destruction of green land back to bare soil. I think man has degraded something like 5 out of 8 billion hectares during its tenure, creating big trouble for the whole food chain.
Oil industry additives may have fuelled a green revolution but after it first raised productivity it then provoked decreased soil productivity, forcing farmers to use ever more inputs to maintain production. That foobar has been masked by fiat sleight of hand.
Your statement is also skimping over the minor issues on the other side of mega carbon fuel use - unbridled pollution. Pollution is gonna kill us off long before any climate related issue.
(This is the danger of current climate crisis policies, diverting the publics gaze away from whats killing us now, to focusing on green-building our way out of a climate "crisis". The causes of hat crisis are so beyond our understanding, that manipulation games can be played for ever.)
Oil pollution and chemical loads are undoing any greening benefits from CO2 creation. Our can-do mindset built on carbon fuel-powered industry has left our species as sick as parrots, infertile, autistic, asthmatic, yadda yadda.
Humankind has also surrounded itself in flammable materials made from oil. One spark and poufffff.
If we can just keep it simple, respect the carbon cycle, the hydrological cycle, the bi-cycle, and understand that homo sapiens has flourished because of a relatively predictable natural environment, unchanged for thousands of years, we will be fine. But most don't want to hear it.
When kids in cities don't even know where milk comes from or what cycle the moon is in tonight, the cord joining billions to nature has been cut...
Peace.
