#12Could we breed trees which capture more CO2? We increased crop yields multifold already: https://ourworldindata.org/crop-yields So maybe we can do the same to carbon yield? Are trees the plants which capture most CO2 per hectare?
Wetlands capture a lot more CO2 and we have lost 85 percent of them globally since the 1700s.

Agriculture production as a major driver of the Earth system exceeding planetary boundaries
Most of it is because of animal agriculture - it uses 80% of agriculture land and about half of our crops.

> Could we breed trees which capture more CO2?
We don't have to breed new trees. The ones we have are enough.
We have enough space to capture 2+x more CO2 than we've released into the atmosphere since industrial revolution.
We could switch to plant-based diets and free an area the size of both Americas.

On that land a regular primeval forest, Miyawayki/Amazon/Syntropic style would grow 10x faster than regular monocultures and that would also enable the biodiversity to rebound. We'd get ourselves out of overshoot in no time (given few decades, of course).

The overshoot threatens our civilization with crop failures. The only realistic way out of it is immediate phase-out of fossil fuels and plant-based diets.

There is a slight danger though. Suppose there is a baseline climate change, Earth is getting gradually warmer on average. Then there is some yearly variation, say, this year above average by 3 degrees, 5 years later below average by 3 degrees. If you call the yearly variation climate change, then five years later your opponents will say "you see, it was a hoax". It is a bit like presidents taking credit for the stoc…
Sure - save for the geophysical fact that we're not seeing just variation .. underlying the usual flux we are seeing a steady increase in heat energy trapped in the near sea | land layer.
This is an inevitable physical consequence of human activity steadily increasing the insulating properties of the atmosphere in a demonstrable and measurable way.
Sure, right now we're going up faster than our new normal rate of increase due to ENSO flux, and in a few years we'll see our rate of increase drop below the current rate as ENSO swings back (fingers crossed) .. but overall on a ten year rolling average we're seeing steady increases in average global temp. as a direct result of human activity (hence AGW) and it'll stay that way until we reduce the insulation properties of the atmosphere.

That is not true, I think most people care dearly and are doing everything to slow down climate change, this includes participating in recycling and watching our own carbon footprints. Ultimately its up to us to convince the policymakers and senior leadership in corporations to make the correct decision.

Imagine a nation with the highest consumption of meat, where individual choices and habits have long shaped dietary preferences. In such a scenario, without widespread adoption of plant-based diets and a shift in societal norms driven by individuals, convincing policymakers and senior leadership in corporations to regulate and promote sustainable diets becomes an uphill battle.
It's through our own choices and advocacy that we can lay the foundation for systemic change and address the pressing issue of climate change effectively.

Huh, "most people"? Maybe in your community, but most of the planet probably don't care. And even if they do those things, only to a degree of inconvenience that they tolerate.. separating plastic/metal/etc? Easy. Missing out on European vacations? "But it's been my life dream to see Italy! It'll only be once in my lifetime!".
And the little plastic recycling they do has the effect of making them think "I'm helping!", when in reality it moves the needle very little...
