IPCC

“All of the scenarios modeled by the IPCC that keep climate change to two degrees or lower by the end of the century agree. In addition to decarbonizing, we're going to need CDR.”

“There will definitely be a moment for government demand. I think when you look at the IPCC numbers for five plus gigatons, five to 10 gigatons of carbon removal, you need public procurement to play an essential role of that.”

“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%.”

“This isn't just a research report because by the end of it, governments approved this report on a line by line basis. They approved the summary of it. So they literally put up on the screen one sentence at a time. Governments will comment on it, suggest modifi…”

“One, when the IPCC runs these models, and we say politically we want to try and keep to a world of 1.5 warming, the models don't close. You can't do it without a whole bunch of assumptions around carbon dioxide removal.”

“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…”

“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 …”

“But I think that the UNFCCC should be aligning closely to the IPCC report's definition of carbon dioxide removal. In that it is a solution that's part of the puzzle to reaching our net zero goals.”

“Today if you look at IPCC's numbers, all greenhouse gases account for about three watts per square meter of warming. That's human activity. The sulfur aerosols we're already emitting from ship fuels, from diesel engines, from coal plants, low altitude, they ca…”

“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.”

“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.”

“All of the oil and gas that has moved around the world is about five billion tons. That is the minimum amount of CO₂ removal that the IPCC says we need.”

“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.”

“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.”

“Where I went from the somewhat concern range to the very, very concern range was that IPCC report and several other reports that came out, culminating in me eventually not being able to sleep, and my wife being like, what's going on?”

“The IPCC, the Intergovernmental Panel on Climate Change, tells us that we need two trillion a year, at least, invested in clean energy systems to have a chance of staying below one and a half degrees C of warming.”

“People have been talking about AI AI ethics and AI governance for a long time, but there hasn't been much dialogue between, you know, this world and then the other worlds of, like, you know, science policy and public policy, and, you know, one way to think abo…”
