"steven hamburg" Discussed on Should This Exist?

"Hi it's katharina asking. Should the success with kelly wasser of silver lining. We've been learning about silver linings experiments with marine salt spray to increase the reflectiveness of clouds. The hope is that this will slow or even stop the steady march of global warming but humans. Deliberately interfering with the climate isn't an easy sell especially to some veterans of the environmental movement. So my experience in talking with albor about this topic very briefly on two different occasions in a decade apart. I'll tell you the stories as a young activist. She got a big big dose of the negativity she'd be up against from an icon of the battle against climate change. I was at the democratic convention. When obama was nominated and i happen to have a floor house which allowed me access to the elevators up and down the stadium and i got on the wrong elevator and i ended up getting off behind the stage and coming off. The stage was al gore with his Suffer that. I said you know honor to meet you and i was curious what you think about geo engineering which i was calling in at the time and he was really unhappy to be asked about it and had a pretty strong reaction. She said she engineering. It's a terrible idea. it's like methadone. We should never do that and interesting that he compared to methadone. I find it interesting because methadone is kind of a treatment but it was pretty clear that this was a sensitive kind of off limits area. And i saw him a decade later At the ted conference and was reintroduced. I wasn't going to bring it up and this person said you know. This is kelly wasser. She works on geo engineering. What do you think. And he's like well you know i'm opposed to that but he was much more relaxed about it. And so i so. I took that as a sign of progress but this is still something that it's not easy for. I think particularly for people who've been working on climate change for a long time. If we were cloud brightening would that just be a quick fix would it weaken the international resolve to reduce carbon emissions or global reliance on fossil fuels and there may be other pitfalls in the hands of the wrong person is. Is this dangerous. The first thing i'll say is unlike some things. It's not an easy technology for one person to sort of go and do you. Very visible from the calculations we've done in silver lining. It's tens of billions of dollars a year. It's not cheap and easy to do. It's not something you can do in secret. It's something that takes a lot of research a lot of cooperation to find out answers to the questions that you want. Like satellites ariel studies them all kinds of things no rogue actors. It's a lot less likely than you think. I asked the same question of dr steven hamburg. The chief scientist of the environmental defense fund supervillain a bond villain who kinda came and Deployed some radical method of changing the atmosphere for example. There's been some movies along those lines. But i was less worry. I mean i think the really challenge we face so obviously people doing various things is always a concern but like any system. This is the most complex we've got right the biosphere the whole earth when you start tweaking. You have unintended consequences. We have to remember. The queuing. Generic is not solving climate change. It's about masking some of the impacts. This is only at its best and if it works out well and doesn't have a lot of side effects an opportunity in a climate crisis to buy some time relative to the worst possible effects of climate change. Kelly one sir from silver lining. She likens it to a medical intervention. You know this is this is. This would not be maintenance. This would be emergency medicine right though. Metaphors are dangerous things. We're talking about all of humanity being impacted by any such intervention or at least large regions. And so we really have to think about it as how would how do you get a global consensus for doing anything got your hamburg has been working on questions of governance for solar radiation management holding meetings on every continent except in article to find out what people are thinking what are the impacts and potential risks. You know the scale of the decision is just unprecedented and so the challenges that there's such a relatively small group people who even know much about this topic thinking about the implications the moral hazard that potentially comes along with deploying of these kinds of technologies. So we're involved in trying to do the governance of the research. That's the first baby steps. So far. I've heard several warnings of caution but no definitive supervillain scenario for cloud brightening so he went looking for perspective. Rooted as much in history has science. I'm just working on a paper. Where people coaches and and slightly more reasonable approaches and then things that we could really do now to help with our climate pickle. We're in a pickle. Yeah and i list. I love you. I love your turns of phrase or in a pickle. Yes jim fleming. A historian of science at colby college says if we're facing unprecedented challenges it's good to take a look at the precedence. I love this approach of taking history and mythology and fiction Referencing walt disney mark twain. Kurt vonnegut ray. I mean you actually say you say You know in fiction writing. There's a moral core that's missing from the speculations of scientists and engineers in his book fixing the sky. He says this history is quote a tragicomedy of overreaching hubris and self delusion but he says speculating about climate. Engineering has a long history. One of his favorite stories is of the first national meteorologist james. Sp in the eighteen forties. The storm king a storm king espy. Yes and.
