Insight
Kann: Voluntary carbon removal must scale 20,000x or become mandatory
“So, within an order of magnitude or so, that voluntary carbon removal market needs to scale up something like 20,000 times. By twenty-fifty in order to reach those IPCC goals, or it needs to no longer be voluntary.”

Opinion
Kann: Limiting warming to 1.5°C or 2°C requires gigatons of carbon removal
“There is no realistic pathway for us to get to one and a half degrees Celsius of temperature rise or even really two degrees without substantial carbon, carbon removal. There's just no way we're going to do it. And substantial being gigatons.”

Koch-Blank: Historical IPCC tables underestimated the climate impact of hydrogen leakage
“There has, I mean, if you go back in the tables that have been developed by the IPCC process and used in all the national inventories for hydrogen leakage, the number has been significantly lower than some of the recent research suggests.”

Shayle Kann: Most IPCC scenarios require storing hundreds of gigatons of CO2
“Most of the scenarios in the IPCC's sixth assessment report, which is the most recent one, include capturing and storing literally hundreds of gigatons, cumulatively, of CO₂ between now and the end of the century.”

Visioni: IPCC estimates surface aerosols masked 0.3 to 0.4°C of warming
“Right now, the IPCC estimates that aerosol emissions from the surface have probably hidden a small fraction of the overall global warming, probably 0.3 to 0.4 Celsius. Whereas Pinatubo itself, just by that outburst of that tiny fraction of sulfate compared to …”

Zou: Transportation gets 30% of climate VC despite causing 15% of emissions
“We've tracked transportation accounting for 15% of total emissions. As per the IPCC 2019 report, but receiving 30% of venture and growth investment since 2020. Whereas on the other hand, you know, energy deals, or energy investment made up 22% of overall fundi…”

Friedmann: IPCC models show 90% of captured CO2 must go underground
“Out of the, say, six gigatons that the IPCC believes we're going to need to do, five and a half gigatons of that are going to be storage. It's something like 90%.”
