@DoctorVive @KenCaldeira While info deficit out of fashion with climate behavioral sci experts @climategeorge,still something to be said for the old Stoic approach, and which you (Ken)have espoused in the past. religionfacts.com/stoicism @KevinClimate @ClimateHuman @flyingless @KA_Nicholas @ryankatzrosene

@DoctorVive @KenCaldeira @climategeorge @KevinClimate @ClimateHuman @flyingless @KA_Nicholas @ryankatzrosene Yesterday I confirmed with a large industrial shell ice manufacturer the efficiency of their freezers (= heat pump w COP 2.5, not heat engine). Expanding on Ken's estimate of 625 tonnes ice melted per tonne CO2 emitted, the cost to refreeze 625 tonnes of ice is $4,000 @ $0.15 kwh

@DoctorVive @KenCaldeira @climategeorge @KevinClimate @ClimateHuman @flyingless @KA_Nicholas @ryankatzrosene Imagine when you take a plane trip that the tonne you emit will melt a 625 M3 block of ice the size of your house incl bsmt, or that if you had to pick up the ice melted by that flight in suitcases up return, it would amount to 6,250 large suitcases of 100 kg each? @ideas_idees

@DoctorVive @KenCaldeira @climategeorge @KevinClimate @ClimateHuman @flyingless @KA_Nicholas @ryankatzrosene @ideas_idees Using @Ricarda_Climate @ALevermann @derp_code & Ken's estimate advances.sciencemag.org/content/1/8/e1… of 625 tonnes ice melted/tonne CO2 released, the cost to refreeze using @BergChilling COP 2.5 freezers is $3,750 - 4,000 for a limited one-step reversal of one impact @MichaelEMann @ClimateFran

@DoctorVive @KenCaldeira @climategeorge @KevinClimate @ClimateHuman @flyingless @KA_Nicholas @ryankatzrosene @ideas_idees @Ricarda_Climate @ALevermann @derp_code @BergChilling @MichaelEMann @ClimateFran Here are calculations to support my statements. The one using CoP was confirmed by @ReNu_Eng and is attached. And
@ecogenenergy pointed out that using a heat pump to reverse the melting of ice might save money but would still leave energy in the Earth system. @CBCQuirks
