Tell me, we have already added 50% more CO2 from pre-industrial levels and what have we seen?

How did you work that out?

Pre-industrial levels was presumably a time when most of Europe had well managed forests. What it didn't have was well managed weather data. We can only go by crop records -which were immediately consumed locally according to local need, not stored and conveyed to other regions.

So what was grown (and how) was regional and impossible to make direct comparisons with agricultural practice these days.

What we have now is insolation at ground level that would be dealt with at tree top height in most countries; which difference, coupled with the two major arboreal effects of trees, navigating to deeper water reserves in dry weather and replenishing moisture in wet and foggy weather (not counting their aerofoil effect on winds and the shelter and subsequent non drying of surface water pools.)

A warmer planet. Next question?

That was the OP question and you have not answered it. Doubling the fertiliser content of the atmosphere wouldn't do that and to say that it does is merely juggling data that deserves to be looked at properly for a change.

Don't dawlish a post just to be clever.
Leave clever to me; you don't do it well enough.

If you want to be clever explain why a warmer planet would store heat energy as heat. And why an atmosphere charged with heat retaining gas would not deliver it above cloud height and dispose of it in the regular way.

And if you want to impress me, tell us why heat isn't directly converted to kinetic energy and disposed of just as quickly.

Or go for the dawlish prize and tell us how it manages to get into 300 feet of water. (And for the gold medal: why it doesn't take the carbon dioxide with it.)

Carbon dioxide is a mantra for idiots. Mere hand waving ploys to get past logic and reason. Fairy tales have there place as dreams do theirs. The trick to watching fairy tales is not to concentrate on the fairy need to wear undergarments over the outer ones and to accept without question what they accomplish waving their wands.

The trick with dreams is to forget them as soon as you wake up.

WAKE UP!
