I guess everyone is talking about "climate change", and its consequences. However if you look back, all these effects of "climate change" accelerated greatly when we started talking about doing something to address the issue. All these "sustainable" power introduced are not actually helping. For example, scientists and enviromental activitists are saying that we need to cut down carbon output as it traps heat, but the introduction of black solar panel and plating earth with solar panels kind of run contrary to reflecting heat back to space. And anyone who owns a solar panel should go check out how hot the panel gets. So why won't global temperature go up?
We are starting to get feed back loops - like the huge amount of fires this year and previous - releasing huge amounts of CO2
Also some things need to gain entry - eg if too much warm water gains entry under the Larsen Ice shelf - it will become unstoppable
If the permafrost melts in Siberia and the artic tundra - it will release methane a huge warming agent - thankfully more short-lived
As to your point - black has been used as a heating method for quite a while
we have increased roadways , concrete to absorb the heat - we use that to aid house warming - with stones inside to collect days heat and release slowly
I did see solutions for reflecting heat back into space
Note lost of ice is also a feedback loop - ice reflects lot of light back to space , so exposed rock will now collect that heat much more ( albedo )
These and thousands of other things are built into the modelling
Anyway one downside of huge arrays of mirrors sending warming light back into space- is that it might kill flying buys overhead - as get hit from heat from all sides
Plus solar panels . mirrors on large scales can change rain patterns - rewarding some countries , punishing others
So have to be careful of unintended consequences - generally planting trees is mostly positive.
Kelp forests likely so
Increasing wetlands is very good as huge carbon sink and huge flood protection mechanism
So not only do we have to cut CO2 - we need to actively remove it from the atmosphere
One of the reasons - we didn't see more effects sooner - is the ocean is a huge huge carbon sink
