The most helpful reminder for me, being now many years past my own emotional reckoning with climate change, is that ignoring emotions is like holding a ball underwater - it takes energy, and eventually that ball is coming up. So yes, even climate old-timers need to regularly check in and take care.

While I have my issues with direct air capture, research into that field keeps producing interesting technologies for future CO2 scrubbers, like these reversible mineralization, which could open up longer durations underwater or in space. 🧪 Link: www.nature.com/articles/s41560-026-…
Electrified capture/release devices and chemical concepts, including eCO2-sMDCR. a, Indirect, bulk-pH-swing device. b, Adsorption/surface mineralization device. In the indirect system, to capture CO2 with kinetics suited for DAC, CO2 is captured by forming CO32−, which consumes two OH−
ions and thus requires two electrons. The reversible CO2 adsorption/surface mineralization device can be operated in a regime employing one electron per CO2. c, Surface chemistry of direct surface mineralization CO2 capture compared to pH-swing CO2 capture. Red: oxygen atoms, purple: metal (Mn) atoms, grey: carbon atoms, white: hydrogen atoms. d, Pourbaix diagram screening of a rangof candidate transition metal oxides. MnO2 avoids dissolution and has a redox window within the water-stable potential bracket at near-neutral conditions.
Data adapted from the Materials Project. e, DFT calculation of the *OCO2H adsorption energy in the form of Mn–OCO2H versus potential. The crossover in free energy circa 0.7 V indicates that CO2 capture and release are tuned using the applied potential. We use the chemical formula MnOOCO2H to denote the formation of Mn–OCO2H on the surface when MnO2 is reduced. Illustration in c was generated by Ovito and the structures for calculation in e were generated by Vesta.
