> is this taken into account in all the models It is in the relevant ones (having “all” in the question makes the question not meaningful). Not only it is in the relevant models, but modelling all the effects includes the aspects that the most probably would never think about. E.g. “bigger crops” store C but it is “returned back” after harvesting. What matters is only what can permanently store C.

Good points but Jungles or Taigas can now also have more mass presumably. I guess that is accounted for in the relevant models indeed.

Yes it is, take a look here how complex it is: https://www.earth-syst-sci-data.net/10/405/2018/essd-10-405-2018-discussion.html https://www.earth-syst-sci-data.net/10/405/2018/essd-10-405-... And it's not just "models" for the predictions, the data about what happens from day to day and from year to year are measured constantly, and all give the numbers that are very clear. CO2 in the atmosphere increases. And it won't be nice. To quote one scientist that first didn't believe, but checked the data and now himself corrects the false claims by those who have some special agendas: "Of the 7 GtC, which we blow into the atmosphere every year, only 3 remain there. 2 are absorbed by the ocean and 2 by the forests. This means that in the atmosphere and in the land biosphere and in the ocean the amount of stored carbon is increasing. And the source of all this additional carbon is the fact that we extract loads of fossil carbon from the earth's crust and add it to the system." "The system was almost exactly in equilibrium before humans intervened. That is why the CO2 concentration in the air was almost constant for several thousand years." Now it's not, even if the biosphere takes some of CO2 the we extract from the Earth's crust, still more remains up there and makes the Earth surface warmer. We measure that year after year already. Here you can find the graph of the measurements of CO2: https://e360.yale.edu/features/how-the-world-passed-a-carbon-threshold-400ppm-and-why-it-matters https://e360.yale.edu/features/how-the-world-passed-a-carbon... Yes, there is more CO2 every year, yes, some CO2 remains in biosphere, but no, there's no balance.
