1. “Introduce your idea in one picture”: Climate science and western policymakers still neglect bamboo, THE plant for resilience, climate adaptation and mitigation, because it can do it all. Worldwide use is a challenge, so start local. Can replace timber, plastic, concrete, edible, grow soil, etc.👇

Hydrogen does not directly warm the climate, but interacts with OH to extend the life of CH4.

"More hydrogen means fewer detergents [OH] in the atmosphere, causing methane to persist longer &, therefore, warm the climate longer"

The Global Carbon Project has just published the most comprehensive Global Hydrogen Budget to date.

H2, although not a GHG, has an indirect Global Warming Potential 37 times more potent than CO2.

Hydrogen emissions are ‘supercharging’ the warming impact of methane - Carbon Brief
The warming impact of hydrogen has been “overlooked” in projections of climate change, authors of the latest “global hydrogen budget” say.

Hansen predicts global temperature will reach a record +1.7°C in 2027. In addition to Earth’s heating rate of 0.2°C per decade, this implies an acceleration by 0.1°C per decade since 2016, likely from (“one-time only”) aerosol effects, ie shift to cleaner and less fuels. mailchi.mp/caa/global-t...

The biggest misunderstanding of Carbon Dioxide Removal (CDR), IMHO, is that many assume it is a replacement for emissions reductions. As in, more CDR, less emission reductions. No. Emissions need to go down as fast as possible, even faster, no matter how much (~feasible) CDR you have.
