Hoping That Sucking CO2 From the Air Will Fix the Climate? Good Luck (easac.eu)

From a study published on Thursday by scientists on the European Academies Science Advisory Council: Senior scientists from across Europe have evaluated the potential contribution of negative emission technologies (NETs) to allow humanity to meet the Paris Agreement's targets of avoiding dangerous climate change. They find that NETs have "limited realistic potential" to halt increases in the concentration of greenhouse gases in the atmosphere at the scale envisioned in the Intergovernmental Panel on Climate Change (IPCC) scenarios. This new report finds that none of the NETs has the potential to deliver carbon removals at the gigaton (Gt) scale and at the rate of deployment envisaged by the IPCC, including reforestation, afforestation, carbon-friendly agriculture, bioenergy with carbon capture and storage (BECCs), enhanced weathering, ocean fertilisation, or direct air capture and carbon storage (DACCs).

Rube Goldberg would be Impressed...

...by the Scientific calisthenics required derive a working AGW theory, that hasn't been show to be true by any empirical evidence.

Anytime some authority insist that you give up freedom or money and the best they can do to justify it is to say, "It's complicated and you wouldn't understand, Trust Us", you know that something isn't right.

Maybe the Wall could consist of thick shrubs that will suck CO2 from the air! Liberals and conservatives will rejoice!

Liberals won't go for ANYTHING, short of capitulation, if the idea is suggested by conservatives right now...

Solutions outside Narrative not credible

[TheZeitgeist]

Solar harvesting (wind, solar cells) and battery cars are true goals for the Warmers. CO2 is the reason we HAVE to do this.

That's why solutions to the CO2 gods that don't involve such goals are "scientifically" calibrated out of the Narrative. That's why natural gas has gone from being "clean energy future" when I was a kid into "methane greenhouse doom" once it became widely available.

This is also why Germany, after sinking all that money into solar cells and windmills - and remember this is land of rising carbon footprints, shiny new lignite coal plants, and diesel scandals - is so "progressive" fighting "climate change" in the same Narrative. Not because of any actual impact on CO2 levels, but because Germany spends tons of public money on windmills and solar cells.

Won't work, we're kinda fucked.

Unfortunately afforestation was one of the approaches considered and found lacking.

This is extremely bad news. In effect, this is the hypothetical "Surprise! Global warming is much worse than previously thought!" news, just from the prevention side. Gigaton-scale carbon capture was necessary to prevent climate catastrophe and now it looks like it's not an option.

In a sane and responsible world this would be an emergency call to action, to replace all coal plants with the most renewable thing people can afford immediately to avoid the worst possible consequences.

Unfortunately this is a world where the world's now-3rd most powerful country and #2 carbon emitter is led by a reality TV star who thinks global warming is a hoax made up by the Chinese, and who just gutted renewable energy research.
