“This is the priority and should be roughly 90% of our collective efforts. The other thing that we can do is take CO2 that we've already put into the atmosphere, already put into the ocean, take it out, and store it permanently. Both of these things you can further break down into supply and demand. There are the things that on the emissions reduction side that consume energy. And then there's where does that energy come from? So we can talk about that in detail, but these are things like making sure that all of our appliances and vehicles can digest renewable energy. And that functionally means making them electric. So we need to make those appliances electric. We need to then power those appliances with renewable sources of energy. So switching from things like natural gas and oil to solar and wind and nuclear, and then we need to attach those two things by updating.”

“Is complicated, and I think the thing that is true about climate is it's our entire global infrastructure. So you have to grapple with the whole thing. But to your point, I think it's hard to digest the details if you don't have a framework to hang those details on. So the way that I think about it is roughly the world admits about 50 billion tons of CO2 equivalents every single year. And in order to stay within reasonable warming targets, we need to get that number to net zero by 2050. And the reason that we say net is because there are some parts of the equation that are going to be really hard to decarbonize. So if we're emitting 5 billion tons by 2050, we also need to be taking out 5 billion tons as well so that the plus five minus five equals zero. And there are two main things that we can do to do this. The first is we can stop emitting in the first place.”

“The source of these emissions is effectively from humans using energy. And humans have been using more and more energy as we've grown in population and as the quality of living has increased. That has traditionally been associated with more fossil fuel usage to drive cars, to power air conditioning, to build things, to get around, these all require energy. And the primary sources of energy to date have been dead plants and dead animals that we have found underground and brought those to the surface and use it to create energy for humans. The crux of decarbonization and the work that we have to do is figure out how can we still enable economic growth for humans and other living things without harmful climate and environmental impacts. And there has been a lot of increasing evidence that this really is possible to do, but that is the work of decarbonization.”

“Today, there are roughly 416 parts per million of CO2 as of 2021 for context back in 1900, this was around 290 parts per million. So that is 43% increase in the amount of CO2 in the atmosphere in the last 120 years. This is the highest level that we've seen in at least three to five-ish million years. It's pretty substantial, and the vast majority of this is driven by humans pumping fossil fuels from the ground into the atmosphere.”
