today on getting answers on this earth day, a new report that shows climate change will make you poorer. how? by how much and what can we do to reverse our

fortunes? also on this earth day, our favorite baseball playing environmentalist, former giant hunter pence and his wife alexis will share their latest sustainability efforts and why you should go to tonight's giants game. but first, frustration with sanctioned line cutting at airport checkpoints. a new california bill that goes after the security screening company. clear. you're watching, getting answers. i'm kristen sze. thanks for joining us. you've seen it at the airports. no doubt. long lines to go through security checkpoints. and you've probably noticed some people cutting to the front of the line using clear, a biometric identity verification system near the checkpoint. that arrangement has many travelers. and now some california lawmakers crying foul. and there's a new bipartisan bill to change the way that pay to play process works. joining us live now to talk about it is jim lights, executive director of the california airports council, that is an organization that advocates for california's

commercial airport interests. jim, thank you for joining us today. >> thank you for having me. >> before we dive into this, bill, i think if you can help by explaining what clear is. >> so as you mentioned, clear provides enhanced passenger screening through biometric methods, either a retinal scan or fingerprints. whereas the regular checkpoint, either that or precheck is simply checking your government issued id document. >> got it. so that's something as a member, you give to clear ahead of time, right? and then they have that. so at the airports at these clear stations you go to the kiosk. and at that point what happens. do you kind of scan your eyes or do you what is what happens to verify your identity, clear customers are offered the option of a retinal scan or fingerprints. >> once that's completed, they double check your boarding pass electronically and then you are

brought to the front of either the regular or precheck security line, and then you go through that line to the to the baggage inspection station. >> okay, i see, so i think that's the part that gets to some people who feel that it's not fair because it does cost about $200 per year. right. so it's not like everybody can afford it. and so for that you do get the privilege of getting to the front of the line after you get verified. so can i just ask you, you know, this bill, what it would do is that it would require that clear to get their own security lanes, if you will, so that it's not like they're kind of moving up to the front of the regular line. what do you think about that? do you think that could work? do you think that is more fair? >> well, it's actually a tsa decision. uh- airports do not control the security checkpoint. that is the domain of the tsa, and it's the tsa that has set up this process. and so while it

might be more convenient if there were a dedicated tsa officer for clear customs, that is entirely a tsa decision. and the reason why airports in the state are concerned about this bill. >> okay, so i should mention it's sponsored by one democrat, one republican. it's bipartisan. so basically, are you saying that if it does pass right, then there was something that needs to be negotiated with the federal government to make it actually happen, where clear operates its own lane clear, the bill would prevent airports from renewing any current contracts with clear and prevent airports from inviting clear into their airports. >> uh. currently, they operate in nine airports in california. they are doing revenue sharing of about 13 million, almost half of that is enjoyed by the primary bay area airports sfo,

oakland and san jose. and so we at airports would lose revenue. and the thought is that airports, along with clear, would go to the united states congress and ask them to make the tsa to provide that dedicated officer for the clear customers, i just don't know that there'd be a lot of sympathy for california if we shoot ourselves in the foot from a revenue standpoint, and then go to congress and ask them to fix our foot for us, in fact, when you talk about revenue, i'm already hearing opposition from the airlines saying that this could lead to flying passengers paying more for their airfares. do you think that is possible? >> because airports are required to be financially self-sufficient as possible, we do that by levying what we call rates and charges to the airlines wherever an airport can

generate non-airline revenue, rental cars, the concessions, your gift shops and restaurants advertising within the airport, along with operations like clear, it helps us keep the airline rates and charges lower. and then airlines will be able to operate at our airports for a less expensive cost. this bill will reduce that non-airline revenue and could indeed put pressure on airline prices in california. >> so i hear you on the cost thing, but let me just ask you about the optics, right. because regular travelers who can't afford the $200 a month seem very irritated that they can just go to the front of the line, right. and unlike the different product, tsa precheck, which is actually not run by a private concessionaire company, but by the federal government, you can say tsa, you know, precheck by allowing some people who pay a much lesser amount to keep their shoes on, keep their

jackets on, not have to take out their laptops, save the collective, everybody some time overall. right. but that clear doesn't do that. it just allows some people to go ahead of others. do you agree that the existence of clear doesn't really save the collective? the overall the whole time? >> well, it's hard to say if clear saves everyone time, but the overall goal of an airport is to make your passage through the checkpoint as quick as possible. and so the tsa has recognized the technology that clear offers and has allowed them to, be in checkpoints where there's space for them. not every airport has space for clear. and again, it's the tsa that has set up the go to the front of the line process. and no one in the state of california has the ability to influence that, except the tsa. >> this is very true. of course,

there are also those who wonder if it has a place something like clear in a federally mandated process, like going through security at the airport. right. so that's a different question. but i want to ask you, hasn't clear had some issues. i know that the whole point is identity verification, but i think in 2022, some person with a false identity got through at reagan national, and it turned out he was going to maybe do some harm. and then there were a couple of other incidents. how do you feel about their, technical stuff there? behind the scenes there are security and there's, you know, how safe it actually is. >> well, they are very, we're we're looking for all airports and checkpoints to be vigilant. and there certainly been some examples where that vigilance may not have been what we want it to be in those instances that you just mentioned. but generally speaking, it is a fairly secure, process. yes. and we think it's just one of the

components of airport security checkpoint operations that we are always looking to see improved, both from the airport side and the tsa side, right. >> i mean, i kind of liken clear to the lightning lane at disneyland, which does irritate a lot of people, you do pay and you do, you know, get to move to the front of the line. so we'll see what they discuss tomorrow. i think the state senate transportation committee will take it up tomorrow, and it could be amended so things could still change. but jim lites really appreciate you coming on to share your thoughts. >> thank you very much for having me. >> appreciate it. thank you. coming up, data shows the environment is paying the price for climate change. and so are we on this earth day. a stanford professor joins us you got it? let's go back to the beginning. are you... your electric future. customized. the fully-electric audi q4 e-tron. get exceptional offers at your local audi dealer. ♪ ♪

awareness to creating a more sustainable planet. while scientists have documented the impact global warming is having on our planet. a new report documents its impact on our wallet. spoiler alert climate change makes us poor. joining us live now is professor noah diffenbaugh with stanford's school of sustainability to discuss the study and the economic impact of global warming. professor diffenbaugh, thanks for your time today. >> thanks for having me. >> so you were not part of the study, right? >> uh- not this study. that's just been published, correct? >> okay. this one was done by the potsdam institute of climate impact research out of germany. but i know you're quite familiar with the findings and the findings of others like it in fact, having done studies of your own, i'm sure. so please summarize the main points here about climate change making us poor. how? >> well, you know, when

researchers look overall at economic growth, it's clear that, you know, hotter conditions for much of the world, really erode economic growth, and, when, researchers look at the building blocks of economic growth, whether it's labor productivity or agricultural productivity or, you know, cognitive, performance, whole, whole suite of measures of what goes into economic growth. they find the same thing, which is that, that, you know, extreme hot conditions really erode, productivity. so we see it, to use the jargon, both top down and bottom up. we see that it's already happened historically and that, global warming will continue to intensify those impacts, as, as we get more and more warming in the future, can you break down

the cost a little bit for us in terms of, i don't know if you can say with each degree of warming, then addition of this much cost and the cost comes from this us having to cope with that. well, you know, there's both, you know, there's, there's what we can measure at the aggregate level so i can tell you about, you know, the research that i've been involved in where we look back at the historical global warming that's already happened and what we find is that, you know, a large number of countries that are already tsay, very warm, that have very large populations and in particular, you know, large fraction of the world's poor populations. those countries have already been harmed by the global warming that's already happened. so india is on the order of 30% poorer today per capita than it would have been if global warming hadn't already occurred. nigeria similarly, about 30% poorer. brazil about 25% poorer. what this means is that overall, globally, inequality between the richest countries and the poorest

countries is, anywhere from 25 to 40% larger today than if global warming hadn't happened. >> really? really. zoom in, please, and explain to me why the person in india is 30% poorer than they would have been had global climate change not happened at all. >> well, you know, it really varies depending on industry and location, but, you know, it's very clear that agricultural productivity, declined steeply, at high temperatures. this is for a broad suite of, of crops. we see that here in the us as as well as elsewhere. we know that, labor productivity likewise has very steep declines on, on the days when, when temperatures are very hot, we know that workplace injuries, even that aren't attributed to heat stress, go up, when conditions are very hot, we know from standardized test score studies of, of standardized test scores linking

, the temperature on the days that the tests are taken across very large, populations of test takers. we know that that cognitive performance declines, when conditions are very hot. so there are lots and lots of reasons that add up to, you know, a drag on, economic productivity when conditions are very hot. >> okay. so then let's talk about how we can cut our future losses, if you will. right. that suggests we need to take climate actions to, you know, to prevent the climbing temperatures. but when governments talk about that, it's usually a problem with cost, how much it costs to make that kind of investment. can you talk about it as an investment and whether to, you know, do more but pay more now? >> yeah. so cost benefit analysis is a really important tool for policymakers and for other decision makers. and in order to do cost benefit analysis, you have to consider, you know, both sides of the equation and there's a lot of emphasis on what will it cost to , you know, curb greenhouse gas emissions. what will it cost to

adapt to climate change? and that's a really important part of the analysis. it's also important to, to quantify, the damages that that will occur at different levels of global warming and hence what will be avoided, if, if, if, we have a lower level of global warming in the future, which, you know, is really a question about, our greenhouse gas emissions and, you know, what we find and what in our research and what this study is reporting, just in the last week is that, you know, curbing, the increase in global warming is a good investment in terms of costs and benefit when we account for the damages from climate change that will be avoided by having lower levels of global warming. >> what about we take this down to the individual level? what can we as individuals do? >> well, you know, the global warming results from global

greenhouse gas concentrations going up. and that's a result of global emissions. so, you know, we each contribute to the emissions of greenhouse gases, there's also a lot that we can do to prepare ourselves for the climate change that, is sure to come in the future. we're not adapted to, the levels of extreme climate events that are already occurring. and we can be sure that, that those will continue to intensify. so there's lots that we can do individually. but i think, you know, the main point is that this is really a global scale challenge. and it's going to take, global scale, action, in order to avoid damages. we're we're not adapted to what's happening now. it's already costing us individually and collectively. and, you know, if we want to avoid, further damages, it's going to require not only reducing greenhouse gas emissions, but also accelerating adaptation real quickly. >> can i just ask you, you know, like the climate, the paris climate agreement, we all made

promises. all the nations. how how far along are we in terms of staying on that track? and are we on track to meeting the timeline stated, well, you know, as the united nations has reported, you know, just this last fall, there's a gap between , what's needed just in terms of the physics of the climate system, what's needed, in terms of emissions reductions to meet the paris global warming goals. you know, there's still been a lot of progress made, but the reality is, is that, you know, we use a lot of energy globally. we need energy, you know, it's a it's a fundamental part of human well-being, most of that energy comes from fossil fuels globally , more than 80% of our of our total energy, is supplied by, by fossil energy sources right now. so it's a really big ship, to turn, it's really, you know,

both of these things are true at the same time. we've made a lot of progress collectively in terms of, working to meet those those paris agreement goals. and that's still leaving us with a lot of global warming to deal with. >> all right. a lot of work to do on this earth day to think about professor noah diffenbaugh, thank you so much. >> my pleasure. >> from home run to hero to environmental advocate, former san francisco giant hunter pence and lexi pence will talk about the nonprofit they created to help save the earth and how you can

you made a cow! actually it's a piggy bank. my inspiration to start saving. how about a more solid way to save? i'm listening. well, bmo helps get your savings habit into shape with a cash reward, every month you save. both: cash reward? and there's a cash bonus when you open a new checking account to get you started. wow. anything you can't do? ( ♪ ) mugs.

♪ bmo ♪ we have your personal invitation to go to a special giants game tonight. >> hello giants fans. hunter pence here at oracle park and i am excited to be celebrating earth day, a cause that is very near to my heart. and my nonprofit, the healthy planet project. >> joining us live now, founders

of the healthy planet project, hunter and alexis pence. hey, happy earth day, you guys. >> a happy earth day, kristin. earth our favorite day. yay! >> thank you. aren't you guys running off to the game soon or something? >> we sure are. >> yes, indeed. we, we first, before we go to the game, we have to kick off climate week here in sf and get that bad boy started. and this is going to be a really fun week for us and a really fun game for the giants starting off the series against the mets. kristen i know it's big. >> i know you're all over the place this week. all for the planet. but tell us about this game tonight and how your foundation, the healthy planet project, is involved. >> yeah. so basically, we are selling tickets to the game and proceeds for anyone that does buy the tickets, a portion of it goes to help the healthy planet project, which is our nonprofit organization that is dedicated to cleaning up the bay area through planting trees, picking up trash, through teaching our youth and educational systems. and it's been an absolute pleasure. so it's a win win. you

get to go to the baseball game, celebrate earth day, watch some baseball, and also help us clean up san francisco. >> and guess what? you would be going to the greenest stadium, which i think the giants video we're watching tweeted that like this ballpark has it all from recycling to composting to the way the field is maintained, right? >> yes. and this year, actually, the giants won the eco slugger innovation award, which is amazing in all their efforts. and i think they do their own like their own bacteria. they grow it there and then they use it for the pesticide on the field, which is amazing. >> absolutely incredible. the details and the links that that the giants go to, to, you know, they've won the award 13 of the, of the 15 times, the green glove award. and this year the eco slugger innovation. they have all these automated drones and this amazing sub air system that's insane with the water. so it's really, really wild what they do and how they're able to, you know, produce a great product, but also do it in a healthy way, which is what earth day is. and climate week is all

about totally. >> and i did not know that the penis shells actually go toward helping grow our is it wines like. yeah they go to, local, local wine, wine, properties, wineries and they compost up the peanut shells and use it as fertilizer. >> so they just find so many amazing ways to, to do things. the right way. and i always love that. it feels so good to be a part of the giants when they're doing that, because it's something that's near and dear to us, but it also, you know, the decision between what's right and easy and they go an extra mile to make these things happen and to do the right thing, and you just feel good about that. it's easy to root for the giants and to be happy to be a part of that family. >> yes, yes. and you know, you guys go the extra mile because i know how how busy you guys have been with the nonprofit. okay. so i'm just going to give you some stats because i know you're a stats guy, last year you guys improved seven neighborhoods, work with 400 volunteers, and clocked over 1200 volunteer hours. and 2024 is just as busy. i think you just did something ten days ago, right?

>> yeah. so niantic joined forces with us and friends of the urban forest, and we planted 28 trees together in the crocker amazon neighborhood. >> look at us this day. yeah, it was day. >> i mean, it is so rewarding, chris. i'm not going to lie. i have an absolute blast doing it. and it's really fun. also to work with with friends of the urban forest. you can always check them out as well, because they also maintain the trees for up to three years. you see, the people in the neighborhood coming out and high fiving you and giving you a thank thanks for, for, planting the trees and, every one of us, we had a really great time. and big thanks to, obviously all our friends at niantic for coming out and showing up. yeah. >> and for folks don't know, you go to the healthy planet project website and you can sign up for upcoming events to work with the two of you right on these amazing projects. >> yes, we also have a great event on wednesday where hunter is going to bat for the bay. and we're having we're going to be interviewing and talking and starting conversation with all the organizations we work with,

like friends of the urban forest bay keepers, save the bay and refuse, refuse, and we'll be having a great conversation over here at the east cut. and we'd love for everyone to come out and come say hi. there's a bay on the bay. let's learn. yeah. >> climate week, it's time to. yeah, yeah. >> and you can head over to healthy planet project.org forward slash donate to get your tickets or to just donate if you aren't able to make it. >> all right. and that's all part of san francisco climate week, which is this whole big thing the city is putting on. you got like businesses that are innovating, right? scientists you got people like yourselves who really care about the environment. it's all there. so check it out. okay. how do we get tickets to tonight's game? the one where you get the discount and you get a chance to win like a date with you, both of you. or just hunter? i don't know, meet and greet. >> just a date with hunter really is no, i'm putting him out for earth. it's a no. >> it's a meet and greet with me, alexis. but the winners have already, have have have already been drawn, so. but you can talk about healthy planet project and get your ticket to this big

opening day, game for the series against the mets through, through our. >> so. yeah, yeah, online for healthy planet project.org. you can find everything there. >> okay. i need a play date with the two of you soon.
