Cooling the planet may be simpler than we think
Trees do more than provide shade. Through evapotranspiration, they release water vapor that absorbs heat and helps cool the atmosphere naturally. The more vegetation we restore, the stronger the cooling effect becomes.
Expanding agroforestry and restoring tree cover could be one of the most powerful natural climate solutions of our time

It might actually be more complex than you think. Evaporation cools down locally. But what goes up must come down. What has evaporated will condense at some point, and condensation increases the temperature by a same amount as the evaporation decreased it. This is just physics, sorry.
And water vapor is a a green house gas, it traps heat.
I still think planting trees is good, but just not for cooling down the planet.
Really, the only solution is to reduce CO2 emissions. It is the only way.

@FransVeldman @samuel26 When I was on the high school debate team, some 50+ years ago, we were debating carbon and global warming and should President Nixon authorize the EPA. It looks like Nixon was right and the
is very wrong to dismantle it! -

Allowing forests to mature back into unmanaged old growth tracts both helps cycle and cool water from the oceans, prevents excessive forest fires but also allows them to serve as important carbon sinks as well. Forests are critical as part of balancing and mitigating the effects of climate change, stopping emissions alone won't be enough it must be both.

I like trees too. That is not the point. But we had more trees centuries ago, even if we would go back to that level, we would still have to deal with the surplus of CO2 we have added since that time.
Again, forests don't cool. Evaporation cools indeed, locally, but the resulting extra condensation warms in the same amount. On the global scale the cooling sum is zero. That's thermodynamics at work.
Also, trees die, and all the captured CO2 is released again when they do. Trees only temporarily hold CO2. It doesn't solve the problem.
We must cut down on CO2 emissions, fast. There is no natural way to deal with all the CO2 that has been released into the atmosphere. Myths that trees somehow deal with this problem are counter productive.
It is like dealing with a leaking roof. Yes, buckets capture water. But buckets are not a solution as long as the roof keeps leaking, and you have no means to empty the buckets. If the only way to empty the buckets is to topple them inside the house, it will not get your house any drier.
We have no way to empty the buckets full of CO2. It is scary. The solution is not "more buckets". We must stop filling these buckets, really fast.

@FransVeldman @samuel26 Yeah, what about so many of us who actually live in Arid, Semi Arid Zones ! Where temperature crosses 40C
