Answer 1

A bit, yes. There is a NASA study showing that *on average*, the world is greening, mostly due to the higher CO2 levels in the air.

However, CO2 is just one of the things plants need, so this effect is limited. There’s a limit to how much CO2 a plant can even absorb, so while many plants *do* benefit a bit from the rise in CO2 levels, it doesn’t mean they’ll continue to benefit from further increases.
