Climate Change, Part 2: Direct Air CO2 Capture
It's not the CO2 emissions we are making today that's causing the Global Warming we are experiencing today, it's the old CO2 in the CO2 Cloud.
After the phase 1 Decarbonization is completed around 2050, the next phase of the Climate Change recovery campaign will be the Direct Air CO2 capture of the 500 billion ton legacy cloud of CO2 that will still be remaining in the air.
And, after that, it may take an additional 100 to 1,000 years for Planet Earth to recover from the ravages of Climate Change.

What does the IPCC (Intergovernmental Panel on Climate Change) call restoration of the environment's CO2 level to it's 1700 pre-climate change level?
Does it ever mention this task specifically?

 

About the Cloud and Where It Came From

How using the atmosphere as a disposal sewer for fossil fuel's CO2 over many years while building and powering the modern industrial countries polluted the air.
We did it because we could and we didn't know anything better. More recently, coal smoke's ' SMOG ' began killing large numbers of people but the reason still eluded most people.

Restoration of the environment's CO2 level to it's 1700 pre-climate change level.

 We have to remove the legacy CO2 remaining in the air to reset Planet Earth's Thermostat to where it should be.

Understanding Climate Change: Keeping Climate Change Terms Sorted Out -
Concepts Used Frequently In Climate Change Part 1 and Less Frequently In Climate Change Part 2

 

Cement, iron and steel, and chemicals account for about 20 percent of global CO2 emissions.
Emissions from these industries are notoriously difficult to abate because, in addition to emissions associated with energy use, a significant portion of industrial emissions come from the process itself.

Do You Understand How Fire Works?
Why Can't Energy Companies Invent Carbon-free Fossil Fuels?  They Can't.  See Below.

Chemistry-ignorant Greenies will never understand why carbon's essential contribution to fire will always give it a place in the world's Energy Pantheon.

Comments about this website

As it happens, this website will be emerging over the next several months in much the same manner as a blog. It will be the writings of an engineer who has had several career encounters with Climate Change since the mid-1950s - before it was generally realized Climate Change existed - had a name, and, until the 1990s, was not considered an existential threat to humanity. While vague hints of long-term changes in the weather were detected as early as the mid-1800s but not realized as significant, the changes brought about by Climate Change between 1990 and today have been startling. For the author, it's as if he has moved at least 200 miles south. The changes between today, 2030, 2040, and 2050 have the potential to be far more startling in both the climate we will experience and humanity's response to it. Now, scientists, policy makers and military analysts increasingly believe that climate change is also leading to rapid globally destabilizing events like drought-driven mass migrations, civil wars and other forms of mass societal unrest. These circumstances make implementing as many full-size Direct Air CO2 Capturing installations as possible imperative now, not justifying leisurely waiting until after a formal assessment of the final results of the Paris decarbonization agreements post 2050.

The inspiration for revising my 'Hobby Web Site' along it's present lines emerged from a paper written by Noah McQueen, Peter Kelemen, Greg Dipple, and Jennifer Wilcox: "Ambient weathering of magnesium oxide for CO2 removal from air", Published by NATURE COMMUNICATIONS | (2020)11:3299 | https://doi.org/10.1038/s4167-02016510-3 |   Nature Communications   https://www.nature.com/articles/s41467-020-16510-3  
 
An excellent color pdf of the paper is available for downloading from the internet.

Your author is a long-retired registered control system engineer with project management experience in multiple heavy industrial process application projects who is suggesting an industrialized agricultural variant of the above basic magnesite Direct Air CO2 Capture idea. It appears to be well-suited for use within the cultural contexts of many of the 180 or so countries of the world having largely agriculture-based economies. By having CO2 farming local, we keep the money for repairing the air local everywhere in the world.
