Carbon Capture – Does it Work?

Harken! Good news (maybe) “encouraging news” is a better description, as Negative Emissions Technology (“NET”) starts coming into focus. Conceptually, carbon removal or direct air capture removes CO2 from the atmosphere, which would be great for suppressing climate change.
In that regard, Elizabeth Kolbert recently interviewed (Yale Environment 360) Stephen Pacala (Princeton professor) chairman of the US scientific panel studying carbon removal under the auspices of the National Academies. Which means the project has top-notch clearances, in fact, blue chip.
Of course, the big question about direct carbon capture is whether it can fix a very big problem created by humans burning fossil fuels like crazed Madhatters portending an ecological disaster-in-waiting because of excessive levels of CO2 in the atmosphere, possibly leading to human extinction way ahead of schedule, too early, or looked at another way, extinction occurring well ahead of scientists’ models. But really, honestly and truly who in his/her right mind “models” human extinction?
Negative Emission Technology -NET- that removes carbon dioxide (“CO2”) from the atmosphere would be a dream come true, assuming it happens fast enough to prevent already-collapsing ecosystems from further total collapse, e.g., permafrost throughout the Northern Hemisphere, especially in the East Siberian Arctic Sea, ESAS, where subsea permafrost covers massive quantities of methane (CH4) in extraordinarily shallow waters. It’s the world’s largest reservoir, and CH4 is the most potent of the greenhouse gases. Problem: The subsea permafrost protective cap is rapidly thinning because of global warming. Already a Russian/American research team has witnessed alarmingly large columns of methane escaping into the atmosphere in the ESAS.
Therefore, the crucial question of the 21st century: Does technology for carbon removal ultimately measure up to the task at hand, meaning, long-term survival of Homo sapiens?
