WEBVTT - How do trees affect the weather? 0:00:01.160 --> 0:00:04.600 Welcome to Stuff you Should Know from house Stuff Works 0:00:04.640 --> 0:00:13.360 dot com. Hey, and welcome to the podcast. I'm Josh Clark. 0:00:13.520 --> 0:00:16.200 There's Charles W. Chuck Bryant, which makes this Stuff you 0:00:16.200 --> 0:00:20.840 Should Know podcast. I don't think I should love us 0:00:20.840 --> 0:00:29.880 see finished please, um, because of that horrible house fire. 0:00:33.479 --> 0:00:36.800 It's good, but it's not quite poetry. What was it? 0:00:37.640 --> 0:00:39.839 I don't think I shall ever see something so beautiful 0:00:39.880 --> 0:00:41.760 as a tree? Is that right? A poem is beautiful 0:00:41.800 --> 0:00:44.360 as a tree? Is it a poem? Okay? Yeah, which 0:00:44.400 --> 0:00:47.479 is really something because what was that Longfellow or Whitman? 0:00:47.760 --> 0:00:51.920 Now I want to say, like Joyce Carol Oates, No, no, no, no, 0:00:52.240 --> 0:00:55.240 we should look this up. Okay, well, while you're looking 0:00:55.240 --> 0:00:58.720 it up, that's really saying something because insert poet's name here. 0:00:59.160 --> 0:01:02.920 Um really was taking his own craft to task and 0:01:03.080 --> 0:01:07.479 appreciated his or her own task. And it was still 0:01:07.520 --> 0:01:11.280 saying that a tree is lovelier than any poem, which 0:01:11.319 --> 0:01:14.160 is a real oded nature. So I said, Joyce Carol Oates, 0:01:14.160 --> 0:01:15.920 but I was in fact wrong. It was in fact 0:01:16.040 --> 0:01:19.480 Joyce Kilmer, who was a dude. I thought for sure 0:01:19.480 --> 0:01:24.520 it was like Longfellower. Huh boy, he is a it's 0:01:24.520 --> 0:01:26.520 a mama's boy if I've ever seen one right there, 0:01:26.959 --> 0:01:29.319 right poems about trees? What he expect? Well, that's a 0:01:29.319 --> 0:01:32.080 great line. Yeah. Uh so we botched that one all 0:01:32.080 --> 0:01:35.320 over the place. Yeah we did, but we're not going 0:01:35.360 --> 0:01:37.560 to start over. It's okay. This isn't a poetry slam. 0:01:37.959 --> 0:01:39.720 This is stuff you should know that. We would never 0:01:39.760 --> 0:01:44.440 slam poetry. Um. Instead, we would spend our time, as 0:01:44.520 --> 0:01:47.960 is our want, promoting trees, talking about trees and how 0:01:47.960 --> 0:01:54.000 great they are. And u uh Val Kilmer his great grandfather, 0:01:54.120 --> 0:01:58.040 Joyce Joyce Kilmer. Uh, he kind of had it dead on, 0:01:58.200 --> 0:02:02.680 because trees are not only beautiful, there are um functional 0:02:03.400 --> 0:02:10.000 and as uh, either Longfellow or Whitman said, nothing can 0:02:10.040 --> 0:02:14.120 ever truly be beautiful unless it's also functional. Oh yeah, 0:02:14.600 --> 0:02:17.400 they didn't really say that. Somebody said it. Uh. And 0:02:17.480 --> 0:02:19.760 you know, we live in Atlanta, Georgia for those of 0:02:19.760 --> 0:02:22.720 you don't know, and we basically live in the middle 0:02:22.840 --> 0:02:25.120 of a forest. If you ever go up on the 0:02:25.160 --> 0:02:27.600 building here or any building in Atlanta and you think 0:02:27.600 --> 0:02:31.040 you're in like downtown or midtown, you just take a 0:02:31.080 --> 0:02:34.280 look out there and you realize, man, there are trees everywhere. 0:02:34.320 --> 0:02:36.040 There's a lot of trees, and people that are from 0:02:36.080 --> 0:02:38.760 like the West or other places where they or not 0:02:38.840 --> 0:02:41.720 as foresty come to the Deep South. Sometimes they're like, wow, 0:02:41.919 --> 0:02:43.240 you know, so in the middle of the forest. It's 0:02:43.240 --> 0:02:45.640 a city in the forest. Yeah, and it's pretty nice. 0:02:45.880 --> 0:02:48.440 It's nice. Nice living up and down the East coast's 0:02:48.520 --> 0:02:50.959 kind of like that, right, um, And we actually live 0:02:51.040 --> 0:02:55.800 in a temperate, deciduous hardwood forest area. Nice, look at 0:02:55.800 --> 0:02:57.680 you from what I understand. Although there's a lot of 0:02:57.680 --> 0:03:02.040 pine trees too, there's those Georgia pines. Yeah, that's true. 0:03:02.520 --> 0:03:07.520 I may be incorrect, coniferous. Well, here's the deal with forest. Um. 0:03:07.600 --> 0:03:10.080 The author of this I take slight issue of our 0:03:10.120 --> 0:03:14.360 planet is is forest land? And she says it's mostly 0:03:14.400 --> 0:03:22.000 concentrated in ten countries the US, Canada, Russia, Sorry, Russian Federation, Brazil, China, Australia, 0:03:22.520 --> 0:03:26.920 Democratic Republic of Congo, Indonesia, Peru, and India. Great, but 0:03:27.800 --> 0:03:35.040 no mention of like Europe, Uh, Germany, Sweden, Finland, Norway, 0:03:35.240 --> 0:03:38.280 like serious forest going on? There is there enough? I mean, 0:03:38.320 --> 0:03:41.040 I know there's the black forest in Germany. Yeah, like 0:03:41.160 --> 0:03:46.360 the boreal forest basically ten degrees above or below the equator, 0:03:46.360 --> 0:03:50.200 you're gonna have rainforest, and then between roughly like fifty 0:03:50.240 --> 0:03:54.800 and seventy ish degrees. Uh, you're gonna have boreal forest, 0:03:54.840 --> 0:03:59.560 which is like Europe and Canada and Russia, and you know, 0:03:59.840 --> 0:04:01.720 it's like a serious stents forest. And she didn't mention 0:04:01.760 --> 0:04:05.240 Europe at all. Those are the northern climes forests. Yeah, 0:04:05.400 --> 0:04:11.080 we're talking coniferous pine, spruce, birch, beautiful, beautiful trees. And Canada, 0:04:11.080 --> 0:04:15.200 of course America is at is lousy with trees. Yeah, 0:04:15.240 --> 0:04:17.080 there's a lot of trees there. It's like Atlanta. One 0:04:17.080 --> 0:04:22.599 point five million square miles of forest land in Canada, right, 0:04:22.680 --> 0:04:24.280 so they got it going on up there. It's and 0:04:24.279 --> 0:04:27.560 that that sounds like a lot, and it is, but 0:04:27.920 --> 0:04:32.080 it's still it's alarming to consider that we lose about um, 0:04:32.200 --> 0:04:39.440 thirteen million hectears heck tear is I think one point 0:04:39.520 --> 0:04:42.919 five acres? Is it? I believe? Uh, well, I do 0:04:43.000 --> 0:04:45.279 know that only I'm sorry, I'm not getting one more 0:04:45.320 --> 0:04:47.800 thing wrong in this episode. You go ahead, and I 0:04:47.839 --> 0:04:53.040 do know that only one I'm sorry. Only roughly of 0:04:53.080 --> 0:04:57.360 the Earth's original forest land is still intact today. So 0:04:57.480 --> 0:05:03.200 over the years has been lost due too, things man 0:05:03.279 --> 0:05:06.640 made and things natural. And apparently we lose an amount 0:05:06.680 --> 0:05:09.720 of forests that's about the size of grease every year. 0:05:10.560 --> 0:05:14.000 So we need Canada. We need Canada's trees. Yeah, and 0:05:14.040 --> 0:05:18.400 you know there are things like forest fires, disease insects, 0:05:19.680 --> 0:05:24.400 competition between species, acid rain, things like that happen. Of course, 0:05:24.480 --> 0:05:27.080 that one is actually man made. And then there's things 0:05:27.120 --> 0:05:30.640 like logging and slash and burn practices, just when you 0:05:31.200 --> 0:05:33.560 cut down trees and burn them to create a field. 0:05:34.600 --> 0:05:38.400 Uh so those are things that man is doing to 0:05:38.480 --> 0:05:41.640 make trees go by by man and nature are conspiring 0:05:41.720 --> 0:05:44.360 to rid us of trees, which we need. And the 0:05:44.440 --> 0:05:48.560 hectare by the way over two acres. Yeah, we'll look 0:05:48.560 --> 0:05:52.039 at that in choke corrections for the first time. All right, So, Chuck, 0:05:52.680 --> 0:05:56.039 everybody loves trees, not the least of whom would be 0:05:56.120 --> 0:05:59.400 Joyce Kilmer. But we like them too, We like having 0:05:59.440 --> 0:06:02.000 them around, and they actually serve a little bit more 0:06:02.000 --> 0:06:05.440 of a function than you would think. Yeah, apparently it's 0:06:05.480 --> 0:06:07.720 not just oh they give us oxygen, which is what 0:06:07.760 --> 0:06:10.960 everyone thinks, which is great. They actually can affect the climate, 0:06:11.000 --> 0:06:15.200 and the climate is defined as a period of weather 0:06:15.320 --> 0:06:19.000 patterns in a localized area over about a thirty year 0:06:19.320 --> 0:06:22.640 at least stretch. I think not many people realize that 0:06:22.960 --> 0:06:26.880 everything else is just weather, yeah, you know, anything under that, 0:06:27.200 --> 0:06:32.360 although I imagine when you start getting into yeah, they'll 0:06:32.400 --> 0:06:35.839 be like, okay, alright, that's climate. Fine, that is true, 0:06:35.920 --> 0:06:38.320 and our planet is warming. We're not going to get 0:06:38.360 --> 0:06:41.719 into the whole rigamarole of global warming and all that entails, 0:06:41.720 --> 0:06:44.040 although we should do that in earnest one day. But 0:06:44.200 --> 0:06:46.800 the climate is warming here on the planet, and it 0:06:46.920 --> 0:06:49.240 is heating up by about one to one and a 0:06:49.240 --> 0:06:53.200 half degrees per years, or at least over the past century. Yeah, 0:06:53.200 --> 0:06:55.600 And I mean that's an important qualifier too, because it 0:06:55.680 --> 0:06:59.960 wasn't supposedly until the beginning of the Industrial Revolution, starting 0:07:00.000 --> 0:07:04.279 around eighteen thirty that um after that we started to 0:07:04.279 --> 0:07:07.880 see temperatures rise thanks to global warming. So the fact 0:07:07.920 --> 0:07:10.520 that it rose by one to one and a half 0:07:10.560 --> 0:07:13.000 degrees in a century, that's significant, even though it doesn't 0:07:13.000 --> 0:07:15.480 seem like much, not to us. You can breathe into 0:07:15.520 --> 0:07:19.400 your hands and raise the the weather around your face, 0:07:20.160 --> 0:07:23.840 um by more than just one degree. Also be foggy, yeah, 0:07:23.960 --> 0:07:28.640 you know, and a little smelly, depending on you know, 0:07:30.440 --> 0:07:35.720 So how can trees affect our climate? Really three main ways? Right, yes? So, Uh, 0:07:36.040 --> 0:07:40.040 the first is to um lower temperatures, which is something 0:07:40.040 --> 0:07:45.200 they do themselves. Uh. Next, they reduce energy usage, which 0:07:45.240 --> 0:07:48.760 is a new phenomenon for trees because we've only had 0:07:48.840 --> 0:07:53.720 like air conditioning for fifties sixty seventy years. But it's 0:07:53.720 --> 0:07:56.480 a new gift that trees give us. And then, um, 0:07:56.520 --> 0:08:00.720 they actually remove air pollutants, which is pretty awesome. All right, 0:08:00.760 --> 0:08:03.080 So let's start with the first one. They lower temperatures. 0:08:03.120 --> 0:08:05.720 They act as a natural air conditioner for the world 0:08:05.760 --> 0:08:10.160 in a way through a process called evapo transporation, no 0:08:10.440 --> 0:08:13.920 huge shock. That is a mix of uh, not a mix, 0:08:13.960 --> 0:08:16.520 but both things going on at the same time. Evaporation 0:08:16.600 --> 0:08:20.560 and transporation, both of which released moisture into the air 0:08:21.400 --> 0:08:24.440 one by way of drawing water from lakes. And we 0:08:24.480 --> 0:08:26.880 talked about in our clouds episode. U's how we eventually 0:08:26.920 --> 0:08:30.320 get clouds. And then transporation is when trees pull up 0:08:30.320 --> 0:08:33.120 water through the roots, work its way up through the tree, 0:08:33.320 --> 0:08:36.760 and then eventually leave from the leaves. Right, And we 0:08:36.800 --> 0:08:39.480 don't actually see like after like a heavy rain in 0:08:39.480 --> 0:08:43.440 the summer, you can see the evaporation going on. Yeah. Um, 0:08:43.520 --> 0:08:45.559 and probably what you're seeing off of the trees is 0:08:45.600 --> 0:08:50.560 actually evaporation off of the leaves transparations of invisible but 0:08:51.160 --> 0:08:54.199 over like the course of a year. Um, a large 0:08:54.200 --> 0:08:58.319 oak tree supposedly can transpire about forty gallons of water. 0:08:58.559 --> 0:09:01.240 That is crazy, that's a lot. Yeah. So they come, 0:09:01.320 --> 0:09:03.760 they bring up all the nutrients through the water, they 0:09:04.360 --> 0:09:07.360 take what they can pee it out their leaves into 0:09:07.400 --> 0:09:11.480 the atmosphere as vapor, not as urine right now. But 0:09:11.720 --> 0:09:14.320 since that's going on, especially when it's going on at 0:09:14.360 --> 0:09:17.360 the same time as evaporation, it produces water vapor and 0:09:17.400 --> 0:09:21.360 it can actually decrease the temperature. That's right. Uh. And 0:09:21.400 --> 0:09:23.400 like you said it, you know, a big thing now 0:09:23.800 --> 0:09:25.559 and it's not now. Actually, that's the funny thing. A 0:09:25.600 --> 0:09:28.079 lot of things that people do now to be green 0:09:28.480 --> 0:09:31.040 are things people did many years ago as just a 0:09:31.080 --> 0:09:35.880 way of life. Homesteaders. Yeah, Like Emily's grandmother and actually 0:09:35.920 --> 0:09:38.360 my grandmother too, they were like, you know, they composted 0:09:38.400 --> 0:09:40.400 and did all that stuff because it was a way 0:09:40.440 --> 0:09:43.040 of life and they didn't have trash pick up homesteaders. Yeah, 0:09:43.080 --> 0:09:45.280 and now we're like, oh, yeah, I composts like, big deal, 0:09:46.160 --> 0:09:48.600 that's nothing new. I mean, it is a big deal. 0:09:48.600 --> 0:09:49.679 You should do stuff like that. But you know what 0:09:49.720 --> 0:09:52.520 I'm saying, people like nowadays think they invented the green 0:09:52.640 --> 0:09:56.280 movement when it was our forefathers really and mothers. Yeah, 0:09:56.280 --> 0:09:59.520 I guess just as long as you're not like burning trash, 0:09:59.720 --> 0:10:02.920 yeah you're doing good. So what led me on that 0:10:02.960 --> 0:10:06.920 mini rant against our people of this age is that 0:10:07.160 --> 0:10:09.520 passive heating and cooling is a big thing now, but 0:10:09.559 --> 0:10:11.880 it was a big thing way back when because before 0:10:11.880 --> 0:10:14.400 they had air conditioners and things, they would, you know, 0:10:14.559 --> 0:10:16.800 plant trees where it made the most sense. Are not 0:10:16.840 --> 0:10:21.679 plant trees, but plant houses between trees where it just 0:10:21.920 --> 0:10:24.880 to grow where it made the most sense. So like 0:10:25.000 --> 0:10:26.480 they say, I think a tree to the north of 0:10:26.520 --> 0:10:28.080 your house, in the south of the house can cut 0:10:28.080 --> 0:10:32.360 down on your energy expenses by how much. Well, a 0:10:32.520 --> 0:10:36.120 heating costs two day percent and cooling costs by And 0:10:36.160 --> 0:10:37.960 you want to plant one at least one tree to 0:10:37.960 --> 0:10:41.640 the west and one treat to the south. Deciduous trees, yes, 0:10:41.760 --> 0:10:44.800 that's the key. If you plant a big old magnolia tree, 0:10:45.000 --> 0:10:48.880 you're gonna be like want, want, want, because while it'll 0:10:48.880 --> 0:10:51.079 cool your house in the summer by keeping some sunlight 0:10:51.080 --> 0:10:54.400 off of conjecting shade. In the winter time, it will 0:10:54.440 --> 0:10:56.959 still keep sunlight off of it. With a deciduous tree, 0:10:57.040 --> 0:10:59.320 they lose their leaves so the sun shines through the 0:10:59.360 --> 0:11:01.959 branches to in the wintertime, So it cools your house 0:11:01.960 --> 0:11:04.920 in the summer by producing shade, warms your house in 0:11:04.920 --> 0:11:08.040 the winter by lightning the sunlight through. Yeah. And I 0:11:08.160 --> 0:11:10.440 love magnolia trees, but boy, you ever had one on 0:11:10.520 --> 0:11:15.319 your property, it's a pain. Waxy leaves that don't disintegrate 0:11:15.360 --> 0:11:19.040 ever or by degrade, they just are there. And then 0:11:19.080 --> 0:11:21.880 those grenades, which were great as a kid when you 0:11:21.920 --> 0:11:24.040 played war, but they're not so great when they're all 0:11:24.040 --> 0:11:27.120 over your yard. Uh. And then pine trees, which I 0:11:27.160 --> 0:11:29.360 love to look at as well here in Georgia, they're 0:11:29.400 --> 0:11:32.160 also a big pain. Yeah, they can be. Yeah, but 0:11:32.320 --> 0:11:35.560 they well, yeah, they don't lose their leaves on an 0:11:35.600 --> 0:11:37.520 annual cycle. They just lose them all the time. But 0:11:37.559 --> 0:11:40.480 they're always they always have the needles, that's true. But 0:11:40.559 --> 0:11:42.959 with the magnolia, though, you also get the lovely scented 0:11:42.960 --> 0:11:46.160 flower and you can snip those off and put in 0:11:46.200 --> 0:11:49.400 a little water bowl in your kitchen. It's like a 0:11:49.480 --> 0:11:53.320 natural air freshener. So my neighbor has stead well, my 0:11:53.320 --> 0:11:56.319 neighbor has a magnolia and one branch hangs over into 0:11:56.400 --> 0:12:00.480 my yard, and so I will clip flowers, uh and 0:12:00.520 --> 0:12:03.000 not really have to deal with much of the waxy leaves, 0:12:03.080 --> 0:12:06.000 which is kind of the best of both worlds living 0:12:06.040 --> 0:12:10.120 the life man so so passive heating and cooling if 0:12:10.120 --> 0:12:12.640 a transporation. That is a great thing that trees do. 0:12:12.720 --> 0:12:15.720 And they can also help cut down on what's called 0:12:15.720 --> 0:12:18.120 the heat island effect, which is bad in cities. Yeah, 0:12:18.160 --> 0:12:20.880 we have that bad here. Um. So there's this thing 0:12:20.920 --> 0:12:24.360 called the albedo effect right where if you are dark 0:12:24.400 --> 0:12:26.960 colored wearing a dark shirt. You're wearing a black shirt 0:12:27.040 --> 0:12:29.800 right now, that's right, you would be hotter in that 0:12:29.880 --> 0:12:33.240 shirt than you would if you were wearing a white shirt. Why. 0:12:33.679 --> 0:12:37.360 I'll tell you why. White shirts reflect sunlight. Black shirts 0:12:37.440 --> 0:12:41.080 absorb sunlight and trap heat. Same thing with asphalt, same 0:12:41.120 --> 0:12:43.199 thing with dark roof tops. And when you put all 0:12:43.200 --> 0:12:47.880 this stuff together, it actually absorbs all this heat traps it. 0:12:48.320 --> 0:12:51.440 And so when you're in a city, it's frequently much 0:12:51.480 --> 0:12:54.000 harder by several several degrees than it is out in 0:12:54.040 --> 0:12:56.080 the suburbs where you have more trees and lawns and 0:12:56.080 --> 0:12:59.080 stuff like that that aren't going to absorb the heat 0:12:59.160 --> 0:13:01.800 quite as much. Yeah. And I lived in Yuma, Arizona, 0:13:01.840 --> 0:13:04.640 as you know, a lot of white cars in Uma, Yeah, 0:13:04.800 --> 0:13:06.840 not a lot of black cars. And they actually have 0:13:07.360 --> 0:13:10.640 I might have mentioned this before, they have like almost 0:13:10.679 --> 0:13:14.640 carpet that they put on their dashboards and it's like 0:13:14.679 --> 0:13:16.400 a thing. It's like fit to the car and it's 0:13:16.440 --> 0:13:20.960 velcrowd on and it saves your dashboard. And they have 0:13:21.080 --> 0:13:24.360 carpet on your dashboard. Yah, pretty much. And you go 0:13:24.440 --> 0:13:26.720 to the video store at the time, this is you know, 0:13:26.760 --> 0:13:29.160 they had video stores back then in the you know, 0:13:29.200 --> 0:13:31.840 mid nineties, and they would have you know, melted video 0:13:31.840 --> 0:13:36.760 cassettes on display because or like the ticketmaster tickets, like 0:13:36.840 --> 0:13:39.079 don't leave them in your glove box or this will happen. 0:13:39.600 --> 0:13:41.960 They catch fire. It looks like they caught fire, but 0:13:42.000 --> 0:13:44.560 they it was just heat exposure. Is that the average 0:13:44.559 --> 0:13:51.480 ticketmaster employee Okay, yeah, yeah, don't just pay a million 0:13:51.480 --> 0:13:55.480 dollars for fees. Uh. So that's the heat all in 0:13:55.480 --> 0:13:59.240 effect in Atlanta, um five to eight degrees hotter and 0:13:59.440 --> 0:14:03.719 Phoenix in nineteen fifty it was six degrees warmer than 0:14:04.280 --> 0:14:07.679 the nearby cass Grande Monument. I don't know why that's 0:14:07.760 --> 0:14:10.520 that is, Oh, because in two thousand seven it was 0:14:10.559 --> 0:14:14.079 fourteen degrees. Okay, I get it. Yeah, so it's getting 0:14:14.120 --> 0:14:17.679 hotter in cities as urban sprawl and the black tops 0:14:17.720 --> 0:14:20.320 of asphalt take over the world. Yeah, exactly. Phoenix isn't 0:14:20.360 --> 0:14:25.760 exactly like a work, live, play, walkable community. It's pretty 0:14:25.840 --> 0:14:29.240 dry v e right, or at least golf CARDI yeah, yeah, 0:14:29.680 --> 0:14:32.000 Well the same with Atlanta. So you've got sprawl which 0:14:32.040 --> 0:14:35.000 is going to increase the urban heat island effect. Phoenix 0:14:35.040 --> 0:14:38.760 is big, big time sprawl. Yes, but trees help counteract us. 0:14:38.840 --> 0:14:41.320 They cut it down. They say, no more of this. 0:14:42.120 --> 0:14:45.800 We're going to provide you passive energy savings and if 0:14:45.840 --> 0:14:49.920 appo transpiration. And while we're at it, you know all 0:14:49.960 --> 0:14:52.280 this horrible air that you're breathing, we're gonna filter it 0:14:52.320 --> 0:14:54.040 for you. We're gonna throw that in as a bonus 0:14:55.160 --> 0:15:00.000 included in the low price. Uh. They will filter dust, ozone, 0:15:00.240 --> 0:15:04.920 carbon monoxide, other kinds of plutants, um and through photosynthesis 0:15:05.400 --> 0:15:08.960 they actually remove CEO two, which is a greenhouse gas, 0:15:09.040 --> 0:15:12.800 as we all know, they remove it and release oxygen instead, 0:15:13.080 --> 0:15:16.680 and they can actually even store it. Yeah, they they 0:15:16.920 --> 0:15:21.600 sequester it in the forest soil. And apparently that soil 0:15:21.800 --> 0:15:26.640 depending on where you are thinking a deciduous temperate forest. Uh, 0:15:26.680 --> 0:15:29.560 that's that carbon dioxide will be stored for anywhere from 0:15:29.560 --> 0:15:32.680 ten thousand to a hundred thousand years. Yeah. I think 0:15:32.680 --> 0:15:36.800 we talked about that. We talked about carbon sequestration before 0:15:37.160 --> 0:15:45.359 or um, what was it desertification? Desertification maybe or earthworms. Yeah, 0:15:45.480 --> 0:15:48.280 we play in the dirt a lot. Yeah, the earthworm one, 0:15:48.320 --> 0:15:50.560 that was a good one. That was a good one. Um. 0:15:50.640 --> 0:15:54.280 So the trees are filtering out the air, but they 0:15:54.320 --> 0:15:58.040 actually and this is a little known Ronald Reagan actually 0:15:58.040 --> 0:16:01.000 once said trees pollute more than cars do any day 0:16:01.000 --> 0:16:04.440 of the week, and he was not entirely wrong. Yeah. 0:16:04.480 --> 0:16:08.200 I don't quite get this. The photochemical smog okay, so um, 0:16:08.280 --> 0:16:13.600 when it gets hot, trees have this volatile organic volatile 0:16:13.680 --> 0:16:18.040 organic compounds, two of which are turpenes and isoprenes, okay, 0:16:18.400 --> 0:16:20.880 and they give them off off of their leaves. It's 0:16:20.880 --> 0:16:22.480 just like it's too hot, I gotta get rid of 0:16:22.520 --> 0:16:27.320 my VOCs and is supremes in particular act as a catalyst. 0:16:27.640 --> 0:16:32.120 They speed up um the breakdown by sunlight of of 0:16:32.800 --> 0:16:37.720 nitrous oxides into ozone, and ozone is a big contributor 0:16:37.800 --> 0:16:40.560 to small. So basically, when when the trees are like 0:16:40.680 --> 0:16:45.280 giving off these volatile organic compounds, they're accelerating the production 0:16:45.360 --> 0:16:50.320 of small indirectly, you know. So when you mix sunlight 0:16:50.360 --> 0:16:55.320 photo with these chemicals photochemical smog, it's from the breakdown 0:16:55.480 --> 0:17:01.040 of like um car exhaust into ozone, which scratches our 0:17:01.120 --> 0:17:03.320 eyes and makes us a cheating it hard to breathe. 0:17:03.560 --> 0:17:05.600 So we should cut down all the treats pretty much. 0:17:06.400 --> 0:17:09.480 That's Ronald Reagan talk. No, of course not. And that 0:17:09.720 --> 0:17:12.119 is that's like the one negative effect that we can find, right, 0:17:13.200 --> 0:17:15.679 oh yeah, other than that trees, well, that and falling 0:17:15.720 --> 0:17:18.600 on somebody or your house or something. Other than that. 0:17:19.040 --> 0:17:21.560 Trees are great, right. That happens a lot Inlanta with 0:17:21.600 --> 0:17:23.719 the heavy rains. Well, it does because we went through 0:17:23.760 --> 0:17:26.560 a drought cycle where the roots all started to come 0:17:26.600 --> 0:17:29.040 towards the surface, and then when you get a heavy rain, 0:17:29.200 --> 0:17:31.480 the trees no longer planted like it was, and it 0:17:31.600 --> 0:17:34.680 just tips over. Just the other day, another guy sitting 0:17:34.720 --> 0:17:36.639 in his car. Man, they love talking about that on 0:17:36.680 --> 0:17:40.840 the news, it'll be like crime, crime crime. Oh, tree 0:17:40.920 --> 0:17:44.159 fell over, let's go cover that instead. That's that's the 0:17:44.200 --> 0:17:46.240 Atlanta News because the boy there's a lot. I don't 0:17:46.320 --> 0:17:49.840 you watch the local news? Uh? Sometimes? Really? Yeah, I'll 0:17:49.840 --> 0:17:51.880 see I'll see it, you know, out of the corner 0:17:51.880 --> 0:17:55.399 of my I haven't watched the local news since I 0:17:55.560 --> 0:17:57.880 was probably in high school. It's good on like the treadmill, 0:17:58.320 --> 0:18:00.639 like when you can't hear anything. It's good for that. 0:18:01.440 --> 0:18:04.000 When they're in front of the varsity interviewing somebody about 0:18:04.040 --> 0:18:05.959 something important, a tree following over, what do you think 0:18:05.960 --> 0:18:10.520 about this? Yeah, okay, so we're talking about global warming? Um, 0:18:11.960 --> 0:18:14.920 can we actually plant trees and get more forest land? 0:18:15.119 --> 0:18:17.560 He actually helped us out. That's how Pearl Jam used 0:18:17.600 --> 0:18:22.200 to do to offset the carbon usage or emissions for 0:18:22.320 --> 0:18:26.120 their tours. Did you know that they planted trees? Yeah. 0:18:26.160 --> 0:18:30.080 They calculate like how much like their jets emitted, um, 0:18:30.440 --> 0:18:33.119 like increcent greenhouse gas the CEO two I think specifically, 0:18:33.359 --> 0:18:36.760 how much like the their fans cars emitted, like on 0:18:36.880 --> 0:18:39.400 the way to the venue, like through for a whole tour, 0:18:39.960 --> 0:18:43.400 and then they calculated and then like they would buy 0:18:43.880 --> 0:18:47.240 an equal amount of trees or however much you know, 0:18:47.760 --> 0:18:50.520 carbon a number of trees kid sequestion. That's how much 0:18:50.560 --> 0:18:53.040 they got the offset their tour. And then al Gore 0:18:53.080 --> 0:18:55.600 started doing it one I don't It was really close 0:18:55.640 --> 0:18:58.760 to about the same time. Um, and everybody thought, this 0:18:58.880 --> 0:19:00.960 is great, this is a great idea. Uh. But there's 0:19:00.960 --> 0:19:03.040 a couple of problems with it. One, once you cut 0:19:03.080 --> 0:19:05.440 down that tree, like that carbon is released in the 0:19:05.480 --> 0:19:10.880 atmosphere prematurely. And then secondly they there was a two 0:19:10.880 --> 0:19:13.920 thousand study seven study that said it depends on where 0:19:13.920 --> 0:19:16.480 you put the tree. If you put in the tropics, 0:19:16.960 --> 0:19:20.560 then it actually will cut down on global warming. Um, 0:19:21.119 --> 0:19:25.800 because in the tropics, trees not only cool the place 0:19:26.480 --> 0:19:30.600 the place by Evappo transporation, it's actually warm enough that 0:19:30.640 --> 0:19:34.200 they produce clouds, which cool the rest of the earth. 0:19:34.480 --> 0:19:36.960 It's like a cloud factory down there on the equator. Yeah. 0:19:37.000 --> 0:19:40.120 We hit that in the rainforest podcast, right Okay. Um, 0:19:40.960 --> 0:19:45.399 in the middle climates where we live, it's pretty much 0:19:45.440 --> 0:19:48.080 a wash. If you plan a tree there for a 0:19:48.160 --> 0:19:50.919 carbon offset, it's not going to really have a net effect. 0:19:51.520 --> 0:19:54.399 If you go up to the borealis forests, which is 0:19:54.880 --> 0:19:58.480 a term you taught me recently. Um, it actually can 0:19:58.560 --> 0:20:03.520 contribute to the heating boreale for us, well, the Aurora boreal, 0:20:04.320 --> 0:20:08.600 which is what I understand now. Um, it can contribute 0:20:08.600 --> 0:20:12.360 to the heating of the planet because remember the albedo effect. Well, 0:20:12.520 --> 0:20:15.480 up there, it's cold enough so that that green canopy 0:20:15.560 --> 0:20:18.840 that's trapping sunlight and hence warmth, is actually going to 0:20:18.960 --> 0:20:22.280 raise the temperature. So this cold climate, cold part of 0:20:22.320 --> 0:20:24.320 the Earth that you used to balance out the overall 0:20:24.359 --> 0:20:28.119 global temperature, if you plant trees up there, it'll warm it. 0:20:28.240 --> 0:20:31.240 Where was Pearl Jam planting trees? Do you know? I 0:20:31.280 --> 0:20:33.760 don't know. Hey, we mentioned Ticketmaster too. They stuck it 0:20:33.800 --> 0:20:36.320 to those guys. Yeah they did. Remember Eddie Vetter war 0:20:36.440 --> 0:20:39.480 like that German World War two helmet and court really 0:20:39.720 --> 0:20:42.919 Yeah he was not happy. Yeah. I saw a lot 0:20:42.960 --> 0:20:45.600 of Pearl Jam shirts at that Sound Garden show last night. Yeah, 0:20:45.640 --> 0:20:48.480 it was people. Uh, you know, it was great. And 0:20:48.640 --> 0:20:50.840 my buddy ended up getting hooked up with V I. P. 0:20:50.960 --> 0:20:53.320 Seats because he knows the guy at the Tabernacle. So 0:20:53.400 --> 0:20:55.399 we were literally like front row of the balcony. You're 0:20:55.440 --> 0:20:58.280 right in the center. Um, but the setless man, they 0:20:58.359 --> 0:21:00.639 gotta work on that. Oh really, Yeah, it's one of 0:21:00.640 --> 0:21:02.439 those deals where I know, I don't I don't want 0:21:02.480 --> 0:21:05.600 to complete nostalgia tour, But when you're coming back after 0:21:05.720 --> 0:21:07.719 that long, no one wants to hear seven songs from 0:21:07.760 --> 0:21:09.680 your new album. Oh yeah, you know what I'm saying. Well, 0:21:09.680 --> 0:21:14.480 I mean, if you're trying to kick start your career again. Yeah, yeah, 0:21:14.960 --> 0:21:17.680 I mean there was a decided energy change in the 0:21:17.760 --> 0:21:20.400 room when they were doing like a bad motor Finger 0:21:20.600 --> 0:21:23.239 and screaming Life and Louder than Love, and then they 0:21:23.280 --> 0:21:25.840 were doing whatever that new album is called, which I 0:21:25.880 --> 0:21:28.440 don't care for, here Comes the Sunshine. Like everyone was 0:21:28.480 --> 0:21:31.560 just kind of like, okay, another one of these, except 0:21:31.600 --> 0:21:34.800 for like, you know, the drunk eighteen year old near me. Yeah, 0:21:35.200 --> 0:21:38.880 this is the only song I've heard finally one I recognize. 0:21:40.119 --> 0:21:42.240 But yeah, good, he sounded great, man, he's amazing. Well, 0:21:42.280 --> 0:21:44.240 I'm just glad that Pearl Jam fans and Sound Garden 0:21:44.359 --> 0:21:47.960 fans are apparently getting along now. Sure it was rough 0:21:48.000 --> 0:21:50.680 there for a while. Yeah, and then you factoring Alison Chains, 0:21:50.720 --> 0:21:56.240 it got really ugly. Go look it up kids music 0:21:56.320 --> 0:22:00.239 of the nineties. You got anything else about stupid trees? No? Oh, 0:22:00.320 --> 0:22:02.560 I do. I have another thing? So you remember the 0:22:02.600 --> 0:22:05.240 two thousand seven study. I was just talking about where 0:22:05.240 --> 0:22:10.840 I misused borealice a two thousand thirteen study this year. Yeah, 0:22:10.880 --> 0:22:14.080 I said, you know what nuts to that nuts to 0:22:14.359 --> 0:22:18.680 Lawrence Livermore Laboratory. We have a computer model that says 0:22:18.720 --> 0:22:23.600 that if we doubled the amount of forests, including boreal forests, um, 0:22:24.160 --> 0:22:28.200 and especially I think boreal forest as soon as possible, 0:22:29.119 --> 0:22:33.320 we would lower the global temperature by a full one 0:22:33.440 --> 0:22:36.959 degree fahrenheight. So we would all set that twentieth century increase. 0:22:36.960 --> 0:22:39.440 Possibly yeah for the last hundred years. That's crazy. Yeah, 0:22:39.560 --> 0:22:42.000 and um, we would increase summer rains by ten to 0:22:42.080 --> 0:22:47.200 fifteen percent all by wow. Yeah, well at the earliest. 0:22:47.320 --> 0:22:49.040 But still so is there a plan in place or 0:22:49.119 --> 0:22:51.240 was that just like we should do this? Somebody's like, 0:22:51.520 --> 0:22:55.600 what can I do with a computer model today? Yeah? 0:22:55.760 --> 0:22:58.400 All right, we'll good for them. Yeah, plan a tree. 0:22:58.560 --> 0:23:01.000 I'm sure there is a program in your community. We 0:23:01.080 --> 0:23:04.120 can go out and uh sponsor a treat to be planted. Yeah, 0:23:04.119 --> 0:23:06.159 but God help you if you plant one in the 0:23:06.280 --> 0:23:11.399
