More Evidence That AGW is a Scam

Whilst the Greta Thunbergs of this world have been wringing their hands and wailing about the disaster that will follow if we don't cut back on CO2 emissions, the planet has been quietly making the most of a good thing.
The planet is greening. Not only has this implications on shrinking the deserts, but it also means that yields of crops have been going up as well.
We are supposed, however to disregard the benefits of additional CO2 in the atmosphere because of a hypothetical disaster that it might cause in the future. Is this not the essence of a scam? For a definite cost in the present, you are promised large but uncertain rewards in the future. It's the same whether it is a "pump and dump" scheme or a ground source heat pump: the promoter walks away with a nice profit and the customer might or might not see their money again some time well into the future.
