#carbondrawdown is going to be essential - yes, we need to stop further emissions, but we also need to deal with centuries of emissions. Large scale deployment of #cryogenicenergystorage generating dry ice serve as a primary means of carbon collection. What already is a good long lasting option for large scale #renewable #energy storage could serve as carbon scrubbers almost for free, just by adding a mechanism to extract dry ice instead of filtering out CO2. https://en.wikipedia.org/wiki/Cryogenic_energy_storage

A #climatechange idea that's been on my mind for a number of years now: Air liquification ( https://en.wikipedia.org/wiki/Cryogenic_energy_storage ) is a viable way of storing energy on its own and particularly attractive at large scale. These systems usually filter out CO2, but dry ice could easily be produced as a by-service of the battery, meaning that a municipal energy storage system could do double duty for #carbondrawdown and #carbonsequestration - pump into ground, use in sequestering industrial processes, etc.

Soils as natural carbon solutions need careful language to evaluate the effectiveness of various strategies. Specifically language distinguishing (1) accrual vs loss reduction, (2) additional storage vs total stocks, (3) C-SOC sourced from C-CO2, and (4) permanence of flux. Currently literature has been remarkably sloppy about these distinctions.

Start-ups are adding antacids to the ocean to slow global warming. Will it work?

A New York experiment is part of a commercial race to develop ocean-based technologies to extract carbon dioxide from the atmosphere.

egads. when those mangroves are gone, cyclones are going to wipe out the people there.

They want to quit. they just need another way to feed their families. #Indonesia #deforestation #charcoal

This is were sensible low tech #CarbonDrawdown would really make sense. They could be growing bamboo and using those furnaces to turn it into #biochar $1 billion spent there would go a lot farther than paying fossil fuel companies for high tech #CarbonCapture schemes.

Burning mangrove trees for a living: 'I'd quit tomorrow if I could'

Indonesia's mangrove forests are being felled to make charcoal - locals say they have to make a living.
