CO2 is bad, nope CO2 is good, OK, forget Greta, let's talk to real scientists..

Anda Andrei
Graph with the level of temperature and CO2 in different geological eras.
It is observed that there were periods with low levels of CO2, but high temperatures, but also with high levels of CO2, and very low temperatures.
There is NO causal link between the level of carbon dioxide and the temperature of the planet.

Pop Emil:
At the moment the planet suffers from a lack of CO2 close to the level of plant extinction, and we are following them.
The level of CO2 must be almost doubled to have jungles again in the current deserts.

Anda Andrei: Pop Emil - Correct, and I'll explain why, for those who don't know.

A high level of CO2 is really favorable for plants and helps them survive in arid conditions much better.

On the surface of the leaves there are some pores/stomata, which are open to absorb atmospheric air with CO2 in it. If the level of atmospheric CO2 is low, the pores must stay open longer, which also leads to the evaporation of water from the plants.

Plants need more water if the CO2 level in the air is low.

But if the CO2 level is higher, then the plants can close their pores faster, which means that they will not lose so much water from inside them and will need less water, so they will survive in arid conditions.

A higher amount of CO2 helps to plant desert areas more easily and to shrink these areas.

Pop Emil:
Anda Andrei, well, you're a candidate for my blog, and I'm going to hit the Greta brats and break their noses with your partecipation...
