6 Ways to Remove Carbon Pollution from the Sky
Having studied most of them and a lot of others not even mentioned, some suggestions are absurd whilst reducing CO2 ... not practical ... others require some invention of limitless power or magic coming along.
Most already previously covered in depth in the 158 pages this thread and some other threads I have contributed to.
I dont disagree with any of what you have said ...
Multi Pronged attack needed. However when brute force removal via use of power to remove CO2 I honestly roll my eyes.
Algae ... seaweed and some other super CO2 absorbents and if someone mentions planting trees that are 2% as good ... I know sadly its a puff piece. Same with brute force approaches.
Possibly putting the smog back up in the air ... it reflects sunlight and when Removal ... sequestration and burying is needed, and not stressed that its say not good enough to say grow algae and then use it as an alternative fuel whilst CO2 neutral ... we need to remove and hide 1 trillion tons of CO2 if not 2 trillion tons.
I am sure some know this and BAS ... whilst I accept we will adapt and likely mitigate some of it, the task the deeper we go into the abyss ,,, setting off cascading effects and some are underway we cannot stop, the more dire and extreme any effort will need to be.
Whilst not wishing to be alarmist, and yes I sound that way, realistically we have passed the point of no return and a 4C rise locked in already. Since as say Smerf says and I agree, political and business will do not a thing and unlikely to do for some time, another 10 years likely will see another 40 PPM CO2 added.
There are things such as making the surface of the planet in vast area reflective, which is more practical and possible than some pie in the sky stuff which requires the power of every power station and nuclear generator to even try and make a dent in CO2, not a serious one ... but a dent.
I have few answers and lots of questions. I suspect a mixture of 5 or more global efforts need to occur and when we cant even agree there is a problem, globally .... politically ... self interest groups rule the world for now.
I do have hope for a regime change and the USA to be come more green as the EU which in turn puts more pressure on others like China and India along with emerging Africa.
I await with anticipation a new regime in the USA.
Or we join Elon Musk going somewhere else.
