Just in case somebody jumps to the conclusion that this is some kind of panacea.
> The researchers are clear that cutting the fossil fuel burning that releases CO2 is the most important action needed to tackle the climate emergency. But climate scientists also agree that, in addition, massive amounts of CO2 need to be removed from the air to meet the Paris agreement goals of keeping global temperature rise below 2C.
Basically we need to stop burning fossil fuels and spread rock dust. Short of some miracle, humanity is screwed.
- ancientworldnow 6y agoParis agreement is also built on IPCC models that ignored methane and many other feedback loops. The new model runs for the updated report coming out soon do not and their estimated temps are almost double in many cases (and more in some).
- ncmncm 6y agoRoughly half of the greenhouse forcing in this century is expected to result from hydrofluorocarbons vented from refrigeration systems and industrial processes. Thus, just cutting CO2 accumulation is not enough; we have to remove enough CO2 to make up for the HFC load. HFC is overwhelmingly harder to remove from the air once vented, and no natural process does. Anything that can be done to remove and incinerate HFCs before they get vented pays handsomely. A ton of HFC traps as much heat as 2500 tons of CO2. HFCs, ironically, were once considered world saviors, supplanting CFCs that were destroying the ozone. Now We Know. Ammonia is the best refrigerant I know of, now. I gather it is heavily used in big industrial applications, but people still worry about it in consumer applications. Toxicity is extremely unlikely to be an actual problem, but people panic if they smell a trace amount.
