way. Welcome to the first episode of Let's Talk Global Warming. My name is Stevie. This is a purely informational challenge, all by fax, come from verified in dependable sources, all of what you can. Check yourselves the links. In the description of this episode, this podcast is going to be all about global warming and its causes, effects and the solutions being proposed by scientists worldwide. I'm also going to keep you update on breaking climate news, including breakthroughs in technology and any catastrophic weather caused by global warming. For my first episode, I figure we should start with what is causing the earth to warm in the first place, the greenhouse effect and what one or two more degrees of warming could mean for our environment. Let's get started. The greenhouse effect is defined as the process through which greenhouse gases naturally heat the earth. Here's how the greenhouse effect works. According to the NRDC, the sun radiates solar energy down on the earth. 30% of that sunlight is reflected back into space as soon as it hits the atmosphere, but the other 70% of the sunlight is absorbed by the earth's surface and oceans for warmth. After the earth is done with that sunlight, it is sent back up to space, So imagine a mirror for a second. If you shine a light on the mirror, it reflects it back up in the same way the sun shines on the earth and the earth reflects that light back up. Now, according to NASA, if this was all the greenhouse effect, did the Earth would on Lee be 0 F? For that reason, it's great that Green house gases exists because without them, our world would be much chillier than it is today. So we've got solar energy being reflected back up into space. Right now. There are also greenhouse gases. Greenhouse gases are gases in the atmosphere that absorb the heat from the earth and reflect it once again back onto earth. If you're still having trouble seeing this, imagine you off to tennis players. The first player hits the ball to their opponent, and in the opponent hits back. Something similar is happening to solar energy. On Earth. The atmosphere hits the solar energy tennis ball down to Earth than the Earth hits it back up to the atmosphere. The greenhouse gases hit the tennis ball, back to Earth and so on and so forth. That's the greenhouse effect. Of course, Without the greenhouse effect, humans wouldn't likely not be able to survive on Earth. However, there is a twist from this podcast. You're going to learn one thing over and over. Humans tend to mess things up a lot, so naturally we also had to mess up the greenhouse effect. We did this by releasing greenhouse gases through activities like burning fossil fuels and raising livestock. This overload of greenhouse gases has resulted in global warmth, hints the phenomenon. Global warming. This effect could be best explained this way. If you were cold, you put on a jacket. But if you keep putting jackets on, you'd eventually get too hot. It's the same thing with the earth. Humans keep putting greenhouse gas jackets on the earth, resulting in a getting hotter. There are five major greenhouse gases that I'm going to talk about. Karma dioxide, methane, nitrous oxide, thorny two gases in water vapor. For each of these greenhouse gases, they're gonna have their own episode. In my next episode, I will be discussing the most well known of the greenhouse gases carbon dioxide. So now that you understand the greenhouse effect, you may now be asking how much hotter hasn't really gotten, according to the inner DC 2014 through 2018 where the hottest years on record, resulting in a global average increase of 1 F since pre industrial times. If no action is taken, scientists estimate that this will increase to 2.7 degrees Fahrenheit between 2030 and 2052 in 2100. This will increase to 8 F. One degree or even eight degrees may sound insignificant. But believe me that even a one degree increase could make the difference between a healthy world in a world dominated by disease, natural disasters and tragedy. Why is that? Well, is defined by NASA? Global average temperature represents an average over the entire surface of the planet. Don't confuse this with the one degree difference in your daily temperatures, like the ones you see on the Weather Channel, those their values vary all the time because of simple things like the season and the time of day. That's not this. I'm talking about a change in the amount of energy exchange between this son atmosphere on Earth, which is a value that varies very little. If you still aren't convinced, let's talk about what scientists estimate this one or two degree difference could do to life on earth. Article from the NRDC vividly describes the tragic future we have ahead of us. If no action is taken to stop global warming, severe weather such as droughts, hurricanes, tornadoes and flooding will become more intense and frequent in dry areas. Extreme heat, worse than what is known today, will result in food supplies depleted by failing agriculture and a shortage of water, which will lead to an intensified risk of human death and disease. Other hand, what areas will experience even more precipitation and flooding than they're used to, which can lead to damages to property in addition to a human health risk as warm, wet environments are breeding ground for many diseases and disease carrying insects like mosquitoes as it gets hotter, there will also become more polluted as hotter conditions often lead to smog. Smog is linked to higher mortality rates for asthmatics and decrease health for those suffering from heart or lung conditions, according to a 2015 study cited in the article. Vertebrae, animals or animals with backbones are already disappearing. Ah, 114 times faster than they're supposed to. Ah, hotter environment is going to make that even worse. In addition, ah, warmer Earth wars on acidification of the oceans as the ocean absorbs excess emissions from the atmosphere, acidification of the ocean poses massive threats to our friends under the sea, especially creatures with calcium carbonate shells or skeletons such as crabs and quarrel. To top it all off, the Arctic temperatures are already rising twice as fast as anywhere else on Earth, resulting in melting ice. Imagine what even more global warming would do to the already catastrophic warming in the Arctic. That's all I have for the greenhouse effect and the quick run through of what one or two more degrees of worth will do to our environment. I know I didn't fully explain many of the topics that came up today, but in the future I will do individual episodes about many of the topics, including the Arctic fossil fuels and the ocean. I hope that all of you learned something new today and are perhaps already realizing how important global warming awareness is in order to fight global warming. We first have to educate ourselves about what global warming is. If we just run into the battle blind, we won't win. That's why I'm starting this podcast by myself. I can't make a huge difference. But with all of you with me, we can make a massive difference. Because global warming is a battle we can win. It's about we won't win if we keep ignoring it like we do now, people have to realize that global warming is real. Global warming will change life on Earth for the worst. If we don't do something about it, it's likely the biggest problem our world will ever face. But together we can beat it. So for everyone listening to his podcast for the first time, I hope that you keep listening and inform yourself about the dangers of climate change so that together we can make a difference together, weaken in global warming, subscribe to this channel today and follow my page on Instagram at talking underscore about underscore global underscore warming so you can stay updated on new episodes and learn even more about global warming. Tell your friends, family and everyone else about this channel so that even more people can be educated about the dangers of global warming. If you have any questions, or if there's a climate change topic you like me to talk about, don't forget to comment below or on the INSTAGRAM Post associate with this episode. Thanks for listening.
