The Japanese have developed a promising new means of direct CO2 capture from the air using a unique chemistry, one which is much more efficient than previous approaches*.
Quoting from the Newsweek article :
"The new carbon capture system is said to remove carbon dioxide directly from the atmosphere "with unprecedented performance," with experts saying that they want to not only slow down climate change but also go "beyond zero" and actually reduce the amount of carbon dioxide in the atmosphere."
and again :
"The expert said that the isophorone diamine (IPDA) in a "liquid-solid phase separation" system was "found to remove carbon dioxide at the low concentrations contained in the atmosphere with 99-percent efficiency."
"They said that it was at least as twice as fast as existing systems and that it uses compounds that are reusable, labeling it an "exciting new development for direct air capture.""

There is little doubt the only hope humans have of reversing global warming and its associated climate change is by dramatic and rapid removal of CO2 from the atmosphere as it continues to rise, in view of the feeble efforts to prevent it.
