Summary
This episode of We Wow on the Weekend features Dennis and Reggie discussing a revisited Wow in the World episode about climate change and geoengineering. The featured segment explores how Harvard scientists plan to use calcium carbonate particles to create a planetary parasol effect, reflecting sunlight to cool Earth's temperature as a temporary climate solution.
Insights
- Geoengineering with calcium carbonate offers a temporary climate mitigation strategy while permanent solutions are developed, buying time rather than solving the root problem
- Natural volcanic eruptions demonstrate that atmospheric particle injection can measurably cool global temperatures, providing a proof-of-concept for human-engineered solutions
- Climate change differs from weather; it represents long-term atmospheric pattern shifts over decades, making extreme weather events like heat waves more frequent and severe
- The IPCC reports indicate a critical 12-year window to reverse climate impact, making interim solutions like solar geoengineering strategically important
- Calcium carbonate was selected over harmful alternatives like heavy metals or sulfur because it's less environmentally toxic while remaining highly reflective
Trends
Growing mainstream discussion of geoengineering as climate change mitigation strategy in children's educational mediaShift in scientific terminology from 'global warming' to 'climate change' to better describe complex atmospheric system alterationsIncreased focus on temporary climate solutions as bridge strategies while permanent emissions reduction infrastructure developsEducational content emphasizing distinction between weather events and climate patterns for public understandingIntegration of climate science education into entertainment-focused podcast formats for younger audiences

Hey WowsR fams, Mindy here, and before we start the show, guess what? You can join me every Friday for two What's in a Wow people who wow edition. In this Getting to Know You game show, I'll be visited by some of the world's most fascinating people to get the wows and the what's of their lives. From cartoonist and graphic novelist Rana Telgemeier of the Smile series to everyday extraordinary kids just like you. And that's not all. With this new season of Two What's in a Wow, there are now two ways to wow. What am I talking about? Well first, you can listen to episodes right here in our Wow in the World podcast feed. OOOR. And this is a big OOR. Yeah, you're right, Reg. That doesn't have the same ring to it. Okay, now where was I? Oh yeah. As always, you can listen to new episodes in your favorite podcast player, or you can watch these episodes with your eyeballs on YouTube. I know! I should comb my hair or something! We are so excited for you to listen and watch our new season of Two What's In A Wow People Who Wow Edition starting this Friday. So make sure you're subscribed to our podcast feed and our Wow Tube channel on YouTube so you don't miss out. That's Two What's In A Wow People Who Wow Edition coming this Friday. And now a quick ad break and then we'll get on with the show. Me and Reggie singing, laughing, and then we... oh wait, no I said laughing twice. Ah, whatever! We Wow on the weekend! Yeah! We Wow on the weekend! Clap, clap! We Wow on the weekend! Cause this is what we do on the weekend! Hello and welcome to We Wow on the weekend! I'm your host, Dennis. And that's Reggie, Mike Ho host. This is the show where we chit chat and answer questions from our fans and listen to TinkerCast podcasts. Hey Reggie, check out all the stuff I got for Goldie Bob, the goldfish's goldfish bowl. Yeah! Look, I got her a water filter so her bowl stays nice and clean and some cool, groovy, colorful pebbles. And I even got her a little pirate ship. Yeah, look at her in there. She's a little book in the air. Captain Goldie Bob setting sail on the seven seas. Or in the seven seas, I guess. Okay, fine. In the one sea, that's not really a sea because it's a fish bowl. Reggie, we're using our imaginations. Hey Goldie Bob, say, egg! Ha ha ha ha! Yay! Wow, all this fish bowl talk is making me thirsty. No, I'm not going to drink the fish water, Reggie. That's Goldie Bob's water. I feel thirsty for a new drink that I want to invent. That's right, it's time for a cooking segment. Dish it up on a dish, anything that you wish, take a bite. That's the list! Dishin' it up with Dennis and Reggie. Today on Dishin' It Up with Dennis, we're going to be making a never been drank before refreshing beverage that will quench my thirst. And first, let's start with this glass that has a little bit of lemon-lime soda left in it. Right, the soda's been in there for a while, so there's no more bubbles left in it. Next, I'll add in some of this raspberry cherry skaterade. Yeah, it's a sports drink for when I'm rollerblading. It has electrolytes. And now I'll take the tea bag from my mug of tea and give my drink an Earl Greyton fusion. No, Reggie, not Earl Grey. Earl Greype. It's grape-flavored tea. It's not gross, it's grape. Then lastly, I'll top it off with some of this chocolate banana peanut butter smoothie I had for breakfast. Yeah, it's a little warm and melted, but it's still good. Okay, there we go. Oops, I spilled a little. Reggie, I know I need to clean up down here. Sheesh, Louie. All right, give that a stir. And now all we need is a straw. No, not that one. We need a crazy straw with the loop-de-loops. Yeah, like that one. Perfect. And there. I call this drink Dennis Punch. Want the first sip of Dennis Punch, Reggie? No. Are you sure? Okay, suit yourself. I'll try the Dennis Punch. Mmm. No, it tastes horrible. How is that possible? All of the ingredients taste good on their own. Why do they taste so nasty when I mix them all together? Oh, you're right. Maybe the next sip will taste better. No, it didn't taste any better. Okay, I'm going to rename Dennis Punch to Nobody Drink This Punch. It's a bad, bad punch. Okay, next up is a little segment I like to call Inside Tinker Cast Studios. Inside Tinker Cast Studios. This is the part where we revisit an episode of one of my favorite Tinker Cast shows. And today, we're listening to Wow in the World Season 3, episode 24 called A Sunbrella for the Planet. Oh, this was the one where it was really, really hot out, and we all went to the beach. Yeah, I love the beach, too. As long as I don't get wet or get sand on me or touch any kind of seaweed or get pinched by a crab or get my sandwich stolen by seagull or get... Right, right, right, right, right. Let's just listen to the episode. Okay, here we go. And play. We Wow will be right back. Grownups, this message is for you. That's it, now back to the show. ["Wow in the World"] You're listening to Bungo and the Two Talk in the Morning on Wobble FM, wobbling your way through the workweek. Whoa, I tell you what, folks, it's a hot one out here today. Yeah, totally, I saw a kid trying to cool off his hot pocket by sticking it in lava. I just saw a chicken land omelet. Oh, but seriously, folks, stay safe out there. Find some shade, drink plenty of water. Yeah, cause hydration is cool. Whee-wee-wee-wee. Yeah. Okay, don't go anywhere, folks. All your favorite summer tunes coming up right after these messages. So, ever heat get you down? Well, then, head on over to the Spit-Tig restaurant. Moist, bitter and... Wow, oh, Mindy, you really picked a hot day to go to the beach. I'm sweating through my elbow patches. Ugh, still can't believe you were able to get a full-body tweed swimsuit Taylor made. Man, does this ice-green truck of yours have air conditioning? I'm gonna need to turn it on. It is on. It is? Uh-huh, see, check out the dial on the dashboard. Mindy, this is set to 90 degrees Fahrenheit. And... Mindy, why in the wild do you have the heater on? Because I wanted to set it to a temperature that would help us to get in the mood for the beach. Well, I'm gonna have to bring this down to a comfortable and climate-friendly 77 degrees Fahrenheit or 25 degrees Celsius. But careful, the button's only held on by gum. Ah, so much better. Ah! We're here! Come on, let's get out before everyone else sees all the sand. Uh-uh, Mindy, my door isn't opening. Oh, yeah, sorry here. I can help you with that. See, I had to recheck up this door after I converted this ice-cream truck into a food truck. And then I had to turn the food truck into a portable ball pit truck. And then I had to turn the ball pit back into the ice-cream truck. And ah! Man, it's not working. So how do I get out? Like this. Hey! Ah! How do you do that every day, Mindy? Steel-toed flip-flops. Now, let's go hit the beach. Whew! Mindy, it must be 100 degrees out here. I'm going to need my parasol. Hold on one second. All right, let me just grab the steering wheel. There we go. Mindy, did you just pull the steering wheel off the dashboard of your ice-cream truck? Uh-huh. Oh, why in the world would you do that? So nobody drives away with the truck. Now come on, let's kick it. Must be like a billion degrees out here. Walk, walk, walk, walk, walk, walk. Man, this beach is packed, Mindy. Tell me about it. Looks like the whole neighborhood is here. Hey, look, there's Thomas Fingerling. Calabunga! Scoop out that epic surf, bro. Toss me on the board. I'm going to hit the lip and then just hang 10. Hey, look, there's Grandma G-Force. Hang 10. Fingerling, you'd be lucky if you could still hang half. No way, dude. I could never hang five. And is that Dennis? Hey, Mindy. Hi, guy. Check it out. I got a new full-body nylon blend swim master bathing suit. Yep, that's Dennis all right. Whoa. I'm fully protected from the sun's harmful rays. The hydrophobic material is as slippery as a dolphin's nose. What is he talking about? Nothing can stop me, except for maybe a jellyfish, or a shark, or seaweed, or a wayward vessel. Thanks, Dennis. Boy, y'all, we're missing is. Reggie! Reggie, what are you doing here? I thought you were meeting your friends in the park. He says that the bird bath was too crowded. OK, Reg, see you later. All right, let's see here. Oh, this looks like a good place to set up. OK, well, let me just set up the parasol here. OK, dope. Stand back, Mindy. Three, two, one. Wow. There we go. OK, let me just get up a beach bag. OK, let's see. What do we have here? I got some beach towels, some sunscreen. SPF 350. UV protective sombrero, microscope. Microscope. Kale chips, some caviar for you, Mindy. Aw, you remembered. Yep. Did you bring the bun so I could make a caviar sandwich? Here you go. Thank you very much. Sunglasses, sunglasses, zinc cream, sun neck protector. Guy Ros, do you think that maybe you're just taking this whole sun safe thing just a teensy bit too far? Oh, no. There's no such thing as being too sun safe, Mindy. And now passing me my sunderware. Ah, I don't want to handle your sunderware. Guy Ros, is there anything in this sun safety bag of yours that's actually going to help us with this heat? Well, I'm afraid not, Mindy. And with the changing climate, these heat waves are just going to become much more common. You mean because of global warming? Well, technically, Mindy, many scientists prefer the term climate change nowadays, because although the global temperature is rising overall, this increase in temperature is messing with the planet's climate. And just to be clear, climate is not the same thing as weather, right? That's right. Weather is what happens in our atmosphere week to week. The climate, on the other hand, specifically refers to larger patterns in our atmosphere that occur over several decades. Ah, so when we say climate change, we mean that long term the atmosphere is changing because of the higher temperatures. Exactly. And a changing climate means more extreme weather like this heat wave. Kingway! Ah! Oh! Oh! Oh! Marley. Thomas Fingerling? What's up? Uh, is that an ironing board? Well, it depends on how you look at it, I guess. Well, why did you bring an ironing board to the beach? Oh, don't be so aggro, dude. This is just my fun board. I use it for new school and the party waves, you dig? Uh. You knew he was going to drop in? It's tubular out there. Well, actually, Mindy and I were just discussing how this heat wave may in fact be the result of climate change. The heat wave is from climate change? Well, if it means more beach days, sign me up for climate change. Sorry, Thomas Fingerling, but that is not how climate change works. It isn't. No, just because it's warmer here doesn't mean it's a perfect beach day everywhere on the planet. Oh, but I thought it was global warming. Well, technically, yes. But now some scientists are preferring the term climate change because the increasing temperature of the planet is actually changing our climate, which may mean more heat waves like this one here. Or it could mean more hurricanes or more extreme snowstorms. Snowstorms? I don't think my fun board will make it through that gnarly pow-pow. The fact is, our climate is a very delicate thing. And if we let the temperature of the planet increase by even 1 and 1 half degrees, it could throw our whole weather system out of whack. Out of whack? That's the name of mine and Chief Forge's hip hop album. Want a bag, happy? Huh? Never mind. It's too cool for you, Quimby's. Mind if I set up my bean bag here in your shade? I can feel the top of my head frying. Of course, Thomas Fingerling. Come, come, take a seat. Yeah, there's plenty of room. Oh, thank goodness. Hey, this is a cool little umbrella you got here, Mr. Razzie. Well, actually, it's not an umbrella. It's a parasol. This one is actually really super special to me. It's based on a design from the Edo period in Japan. It's super handy on hot days like this. Here, look. Hot. Cool. Hot. Cool. If only it was this easy to cool down the planet. Uh, say that again? It's based off a design from the Edo period in Japan. No, no, the other thing you said right after that. Oh, if only it was this easy to cool down the planet. Yes. Well, what about it, Mindy? Well, maybe it is. What are you talking about? I'm talking about throwing shade. Throwing shade? You mean that new TV show where two people sit down and then salt each other in front of a live studio audience? I said your fashion sense is little more than that of a whiff of a waffling saddle goose. Why would you say that? Let's throw chairs. I'm not talking about the TV show throwing shade, Guy Raz. I'm talking about the Olympic event where you hurl umbrellas like javelins. Really? No. I'm talking about a brand new research project from Harvard University where the scientists plan to basically create a great big parasol for the Earth. Wow, for real? Yeah, but instead of using fabric like your parasol here, these scientists are going to be using antacid to help control the temperatures down here on Earth. Antacid? You mean like the kind of medicine you might take if you have an upset tummy? Yep, same stuff. Oh, yeah, that's what I used to control my tubes. Gazooom tight. Pardon? So many how in the world are these scientists going to use stomach medication to help cool down the planet? Well, Guy Raz, the technical name for this stomach medication is calcium carbonate. And it's the same stuff found in snail shells and limestone. And what these scientists are hoping to do is to release particles of this shiny and reflective chemical into our atmosphere to reflect some of the sunlight back out into space and bring temperatures under control here on Earth. Kind of like how this parasol is blocking out some of the sunlight on us and keeping us cool. Exacteritos. It's a process called geosolar engineering, which is basically just a fancy way of saying altering the atmosphere. Geosolar engineering, huh? I think I've heard about this before, Mindy. Oh, yeah? Yeah, what you're talking about is humans purposely altering the atmosphere to try and lower the global temperature. But you know, this kind of geosolar engineering happens from time to time in the natural world. It does? Yeah, especially after volcanic eruptions. Volcanic eruptions? Yeah, after a volcano erupts. It spews tons and tons of dirt and sulfur way up into our atmosphere. And it blocks out the sunlight and creates a sort of giant parasol around the planet. Just like what these scientists are trying to do. Exactly. In fact, there was a famous case of this in 1963. A volcano in Indonesia erupted and it lowered the Earth's average temperature by 0.7 degrees Fahrenheit that year. Wow, was it because the ash from the volcano threw shade over that part of the planet? Well, that's what the scientists concluded. Whoa, that's so wow. Balloons here, get your balloons here. I'm going to get me some raccoons. Where's my pocketbook? Where my GeForce where'd you come from? I've been here this whole time. You didn't recognize me on account of fingerling made me into a sand mermaid. I got flippers. I don't work. Oh. Balloons here, get your balloons. Oh, I want one. Excuse me, sir? Sir? Yes, hello, ma'am. Yes, I would like one of your finest balloons, please. Well, these are all the finest. I've got gas, hopper, cluster, water, solar, fire, observation, decoy weather, and if you're looking to spend the big bucks, I've got a hot air balloon back in my van. Hmm, I will take one weather balloon, please, and thank you. That's the type of balloon that they're planning to use to spread the calcium carbonate into our atmosphere to make that giant chemical parasol. Okey-dokey, here you go. One eight foot diameter weather balloon. It's filled with helium, so if you let it go, you're probably not going to see it again. Whoops, I let it go. Sorry. Oh. OK, here's another one. Make sure to hold tight this time. Will that be all? No, actually, that's not all. You wouldn't happen to have a couple of pounds of calcium carbonate on you, would you? Nope, sorry. Just sold my last bucketful to that lady down there. This ain't no sherper. Are you liking fingerling? No way, dude. Oh, is she eating the calcium carbonate? Grandma G-Force, don't eat the calcium carbonate. Yeah, don't eat it. I'll do what I want. That's true. She does. OK, so what does this balloon have to do with climate change, Mindy? What? Oh, right. Yeah, so those scientists from Harvard University are going to get that calcium carbonate up into the atmosphere with a weather balloon? Well, with a custom made weather balloon. So it might look a little different from this one. Right, right. So how would it work? OK, so later this year, these scientists plan to send this specialized weather balloon 12 miles up into our atmosphere, where it would then use a propeller to stir the calcium carbonate into clouds. Which hopefully will then reflect some sunlight back out into space. And cool the planet. Right, so why calcium carbonate, Mindy? I mean, I know it's super reflective, but why not something else? Well, I mean, you can't just go around putting anything you want into the atmosphere. That is true. I mean, putting too much carbon dioxide into the atmosphere is what got us into this climate change conundrum in the first place. Right, so the scientists did a bunch of testing with a bunch of different chemicals and found that heavy metals like chlorine, for example, would be bad and toxic for the environment. And what about sulfur? Because that's the primary chemical that's found in all those volcanic eruptions. Well, they tested that too and found that calcium carbonate is even less harmful than that. And it could even help heal some of the damage that has already been done. That's amazing. But, and this is a big but. I get it. This is not a solution to climate change. But Mindy, I thought you said this was going to reduce temperatures here on Earth. Well, that's the idea, but it won't last forever. So this is just a temporary plan? Exactly. Think of it like putting tape over your leaky nose. It's going to hold your snot in for a while, but eventually you're going to have to get a new nose. But if this works, it will dolphinately buy us more time. And boy, do we need all the time we can get. But by the way, did you ever read that IPCC report I sent you? The ICUPP report? No, Mindy, the IPCC, the Intergovernmental Panel on Climate Change. All right, the ICMEPP report. Yes. No, I did not see that. What did it say? The IPCC or Intergovernmental Panel on Climate Change is a group of scientists from all over the world who've gotten together to try and figure out how we can stop and hopefully reverse climate change. And what did they figure out? Well, in a report they released in 2018, they said that we have just 12 years to turn this ship around and start reducing our impact on the climate. Oh, man. So even though solar geoengineering might not be a permanent solution to climate change, it could help buy us some more time to figure out how to do that. Well, that's the idea. Incoming. Ah, it's raining volleyball. Climate change is here. Run. Mr. Fingerling, are you all right? Oh, yeah, sorry. I just had a bad dream, is all. Now who's hitting volleyball out my noggin? Reggie did it. Dennis? Mindy? Guy? Little help? I don't suppose you guys want to play doubles. Mindy, do you want to play? I'm in. I was a volleyball champ in 1932. Back then we called it lofty smash. Waterbat teams three and we all used Dennis for the ball. Oh, ha, ha. Fine. Teams of three, but we're playing by European standardized rules and I will be enforcing them. Now, when it comes to the utilization of the so-called five and one system, I think it goes without saying that we should only be allowed. Wow, that was so cool. I didn't remember all that stuff about using calcium carbonate to shade the planet. Because Reggie, I was busy being really great at beach volleyball. What? I did not cheat. If anyone cheated, it was you. When you served the ball, your toe was over the line. What? I did not touch the net. Uh-uh. Uh-uh. Uh-uh. OK, fine. I demand a rematch. Right, let's wrap up the show and then it is on, Reggie. Thanks to all you listeners out there for tuning in to WeWow on the weekend.
