There are a lot of underlying governance mechanisms, and we need them and we need to grow them faster in order to manage all sorts of problems of which climate is just one. What we’re doing is roughly 100 times faster than the natural pace of climate change over the last, say, few hundred thousand years. David Keith: Solar geoengineering is the idea that humans might deliberately alter the amount of heat the earth absorbs from the sun. So I do see climate as the most important global-scale environmental problem. David Keith (born May 8, 1954) is famous for being movie actor. Art by Niko Yaitanes/Harvard Magazine; images by iStock. I think we will get to some level of federal consensus and power around decarbonization that will be slower than a kind of 20-year pace that I said, but quicker than the 200-year pace Dan said, but it will require some political discontinuity between now and then. It required either foregoing inexpensive fossil fuels or replacing them with technologies that were pretty much all much more expensive.

And the answer is, in the end, the governor of Connecticut can be overruled federally, just to take that example. Photo collage by Harvard Magazine/JC.

If you’re going to allow every individual local person to fight every installation all the way through the court system, you’ll never do it. I would sort of see two end member pathways and the reality of the world is likely to be somewhere in between. Jonathan Shaw: And David, do you imagine solar geoengineering being used as part of a larger decarbonization project? It’s extremely hard to transition. Daniel Schrag: Well, I think there are many lessons from the paleoclimate record. Because if someone did develop a way of doing this at a much, much lower cost, it would be incredibly consequential. I’ve had lots of interviewers ask me if I think solar geoengineering is inevitable, and the answer is certainly not. I can easily imagine situations where it’s avoided. And I think with decisions like that, I think you can do in just a few decades, but with enormous social and actually other environmental consequences. And so when I look at that, I say, “Boy, I’d love to imagine that it could happen in 20 or 30 years. But when they actually get together to talk about a terrorist attack in Paris, or in New York, or whatever, they actually talk with their top military advisors. And the frustrating thing about this problem is, it’s important. Climate changes now underway are occurring at a rate 100 times more rapid than at any time in Earth’s geological history.

DETAILS BELOW. And I think that this is not just for my mind about managing human risks. But I worry that humans’ ability to kind of get used to their surroundings means their willingness to sacrifice to return to something that has much lower carbon dioxide is going to be a challenge. And my hope is that technology can be wind in our sails. Graded out best on the mound as a righthanded pitcher. There’s no value-free answer for how quickly we should cut emissions. But I think it’s important for everybody to understand the difference between what we see in the geologic past with warmer climates and higher CO2 levels and what we’re experiencing today.

I think there’s some value in leaving the natural world that we evolved out of, that we inherited, leaving as much of it as we can for future generations to love, to serve as an anchor for their civilizations. David Keith: Thank you. Great to be here. Loose and fluid swing with consistent hard contact and line drives. So one track is the, you might call it the UN system process, the IPCC, all these meetings, all this conversation about something that points to a global consensus. Another risk is the fact that solar geoengineering is not anti-CO2.

But if your home is under attack, you’re going to figure out.

Take over a bunch of siting decisions in a way that’s very different from what we’re familiar with in democracies.

I think it’s going to be really difficult. So to me, reality is in between those two rails. That’s exactly right.

I think that climate change itself is going to ultimately push us into new forms of global governance. In the past, when we’ve had times with higher carbon dioxide levels and warmer temperatures, the changes have been very slow. Fall 2020 TV Lineup: What You Need to Know About the New and Returning Shows Here's What's New to Stream in October on Netflix, Hulu, Amazon, Disney+, and More David Keith But in human terms, at this early stage of climate impacts such as rising seas, rampant wildfires, and intensifying storms, the pace of change has been perceived as slow. The timescale, and this is why I actually think the way you do it is really important, some people have advocated low level cloud modification.

And so we moved to a very loose Paris agreement where countries offer their own commitments and set their own targets with maybe a little bit of peer pressure but certainly nobody’s telling anybody what to do. So I think there are lots of examples like that where global governance has grown. And then there’s a final binding decision and it’s backed up by troops. Loving husband of 53 years, David Keith Perry, was born in Toledo, Ohio on October 10, 1947 and passed from this earth on August 26, 2020.

That is, if we go to still higher CO2 levels, 450, 500, 550, essentially, we’re going to melt the entire Greenland ice sheet. What David said is exactly right, that doing something on that timescale means forget permitting, you’re just going to build stuff. So you just to do that 20 gigawatts a year, 4,000 gigawatts. But not all problems have to be the absolute most important problem. David Keith (December 27, 1973 – October 22, 2020) was an American professional stock car racing driver and spotter.

But I think that wouldn’t be a very good outcome, because in the long run, I suspect that’s not very stable. In some places it will certainly increase some climate changes compared to pre-industrial with consequences. Small stride into contact with a high hand set and high back elbow. So it is a no-brainer that some countries, oil companies or whatever, will over-claim at some point about how solar geoengineering might work as a way to avoid emissions cuts. He is survived by his wife, Constance Lee (Ocheske) Perry; Children, Paula and Robert Roe; Pamela and Tracy Skaggs; Patricia and Reid Rossmann. The Harvard Initiative for Learning and Teaching conference considers classroom inclusion and equity. We’re tribal, we’re nationalistic, and we’re really bad at long time scale problems. vs. And there are certainly ways to do it that would have very high risks that would be just crazy, wantonly destructive. https://www.perfectgame.org/Players/PlayerProfile.aspx?ID=535172 Class Notes or Obituaries, please log in using your Harvard A late drive leads to a legendary ’66 win over Dartmouth. And not only do we have to do it here in the US, but it has to be done globally. I think the key point I’m trying to make is these are human choices, political choices, and we shouldn’t imagine there’s some technocratic, turn the crank value-free answer. Since natural mechanisms of removing CO2 from the atmosphere operate slowly, is there a way to remove carbon from the atmosphere at scale? So it’s losing mass every summer. So there’s no way to separate out discussion about what the risks are from discussion about what engineering choices are made in implementing solar geoengineering? Or what if there’s a global war? That might be done by putting reflective aerosols—these are just tiny little particles of dust—into the upper atmosphere, the stratosphere, maybe 20 kilometers above our heads.

Jonathan Shaw: Thank you both for joining us today. community. So, in the near term in the U.S., you do a lot of solar, because the solar capacity factors are much higher, and you do that associated with a huge amount of long-distance transmission. I mean, imagine now when the G7 get together, and they come out with some statement on climate, which I guess President Trump didn’t want to join, but imagine they actually did all come out with some statement on climate. Daniel Schrag: I step back from it. And people buy electric cars because they’re better choices, not because the government tells you have to, or because the government subsidizes them heavily. I mean, new technologies and new interconnections require different kinds of global governance. But if you want to do that in a couple decades, you need a level of command and control that’s akin to wartime where you simply nationalize a bunch of industries, shut down a bunch of things you don’t want.

What does paleoclimate data suggest lies in store for us at current CO2 concentrations, which reached a seasonal peak of 417 parts per million in May 2020? You can go on and on. And so it’s worth funding a lot of different ideas at this stage because we just don’t know at this point. That’s very general. What is the risk that the fruits of solar geoengineering research might be used to lower Earth’s temperature without addressing the underlying cause of the warming? Your donation today Certainly the environmental groups want to make this an urgent problem. And how long would that conversion take? I think the fires in California and Australia and Greece are just a little bit of a wake-up call. And the technology cost gets cheaper. I don’t mean a revolution. And I think that’s going to make it very attractive.

That is, right now some of the new technology is looking like it’s going to make this problem a lot easier. So let’s say that you want to do it on wind and solar. David Keith: So I personally don’t think that trade-off would be ethical, but I don’t think it’s technologically impossible. Can solar geoengineering, the lofting of reflective particles into the stratosphere, help stop this runaway train?
