@aliebman@frankjotzo good point.
1.5+ ºC of heating is already “committed” from historical emissions b/c hysteresis in climate & attendant ecosystems (eg Amazon is now a net emitter not sink + coral reef decline → trophic sea-life decline → less sink)
also coal today emits >0.2 ÂşC of cooling SLCP.
@aliebman@frankjotzo a point I & others have been making for a decade is one stock & flow literate economists should be able to grasp (heck, even IPCC WG3 has figured this out but are not leveraging it…)
*rapid elimination of methane emissions* is best tool we have to reduce the peak temp of AGW.

@ChristieKngstn@VMorganSchmidt@D_LittleproudMP@farmingforever@BZELandUse NFF talk a big game but no plan to get there. None of their cell-grazing/HM trials have demonstrated simultaneous lower emissions & increase in production levels. @UNFCCC method used in AGEIS inventory is VERY deficient in aggregating Ag sector emissions which takes time… [cont]
@ChristieKngstn@VMorganSchmidt@D_LittleproudMP@farmingforever@BZELandUse@UNFCCC 2. …to explain. The @BZELandUse Report went to great effort to comprehensively assess all Ag emissions not just those counted by AGEIS system. They find using GWP20 (which is relevant when a lot of SLCPs r in the mix) Ag is 54% of national emissions. Using GWP100 soon be ~50%.
