A new article in Science looks like we might have another 'silver bullet' for the climate crisis:
Chemists at the University of California Los Angeles said the crystals — which go by the name zeolitic imidazolate frameworks, or ZIFs — can be tailored to absorb and trap specific molecules.
"The technical challenge of selectively removing carbon dioxide has been overcome," said UCLA chemistry professor Omar Yaghi in a statement.
This is clearly great news - a could be a big piece of an intermediate solution. I think it's important to remember at the same time that increasing concentrations of CO2 in the atmosphere are but one sustainability challenge (albeit one that is of great magnitude, urgency, and to which we all contribute). There are still many sustainability issues associated with our fossil fuel based economy - the physical destruction of nature from coal mining, the social injustices of exploitative oil extraction, etc. So let's hope this works, and at the same time keep our eyes on the big prize, of a holistic, comprehensive vision of a truly sustainable, healthy, just, and caring society.
