Welcome to Let's Tuck Global warming. My name is Stevie. Just as a reminder, this is a purely informational channel. All my facts come from verified and dependable sources. For this episode, you'll be able to find the source is in the links underneath the episodes about the topic. For example, if you want to know more about the greenhouse effect, go to the links underneath the episode about the greenhouse effect or listen to the episode self. If you haven't already, we have gone through all the greenhouse gases, and now I'm going to use this episode to summarize their characteristics and why they're dangerous for our environment. First, we have the greenhouse effect. The sun radiates solar energy onto earth surface. Usually when it hits our surface, the radiation is reflected off of Earth's surface and into space. It's like if you shine a flashlight onto a mirror, the mirror reflects the light back up. Same thing with the sun and earth. But Earth cannot support life with the heat of this light alone. So there are also greenhouse gases. Greenhouse gases absorb solar energy, reflected off of Earth's surface and reflected again back onto earth surface. It's like two tennis players hitting heat back and forth between each other. This process is the reason life could be supported on Earth. However, due mostly to human activity, the amount of greenhouse gases has increased, which has in turn also increased that temperature on Earth's surface, resulting in global warming. Think of it this way. If you put on a jacket, you were warm. But if you keep putting more jackets on, you'll eventually get too hot. Humans keep putting more greenhouse gas jackets on Earth, which is making Earth way too hot. The five main greenhouse gases being admitted that result in global warming are carbon dioxide, methane, nitrous oxide, Floren ated gases and water vapor. First, there's carbon dioxide. Carbon dioxide is the most emitting greenhouse gas and was responsible for 81.6% off all US Green House gas emissions caused by human activities. Carbon dioxide is a dangerous because it's powerful, like chlorinated gases. Carbon dioxide is dangerous because of how much of it we emit. Carbon dioxide is admitted in many different ways. The main sources from the burning of fossil fuels to produce products such as electricity, fuel for automobiles and other products, like plastic and chemicals. Deforestation, which is the act of cutting down large amounts of trees, results in a substantial amount of emissions. Carbon dioxide is not only absorbed by trees to make into oxygen photosynthesis, but it is also stored in trees, so cutting down trees prevents carbon dioxide from being taken out of the atmosphere as much as it also releases it. Another major source of carbon dioxide emissions are industrial production processes that require chemical reactions that produce carbon dioxide as a waste product, such as in the production of steel, concrete and I WR. Second, there's methane. Methane is released. In many ways. Methane is released in several natural processes, especially from microbes in the wetlands who breathe out methane instead of carbon dioxide and respiration due to low oxygen levels in well and wetland environments. Due to warming, permafrost, which is ice of his supposed to stay frozen all year round, is melting, releasing methane and other gases that abyss store within them for centuries. Livestock production, in the form of animal's digestive processes in decaying fecal matter, is the largest emission source of methane from human activity. The natural gas and oil industry also contribute to methane emissions, as methane is a key component about the natural gas and oil. Lastly, treatments of waste border and landfills contribute to rising methane emissions due to poor treatment strategies and poor containment of emissions. Third, there is nitrous oxide. Nitrous oxide, also known as laughing gas, is a medical numbing chemical as much as it is a powerful greenhouse gas. Nitrous oxide lasts around 120 years in the atmosphere, which is 12 times as long as methane and is 300 times stronger than carbon dioxide. Nitrous oxide also reacts in the atmosphere to produce nitric oxide. This nitric oxide damages the ozone layer, which is a layer of the Earth's atmosphere that blocks dangerous ultraviolet rays. Nitrous oxide comes from multiple sources. Nitrogen fertilizers are extremely important to a successful crop in many countries who wouldn't have otherwise had it. But the overuse of nitrogen fertilizers has led to half of the nitrogen fertilizers being lost as nitrous oxide, nitro fication and denied certification. Also, women nitrous oxide as a waste product of both processes when manure is uses fertilizer or when it decomposes and waste facilities and out in the open. It produces an abundance of nitrous oxide as at least into runoff and decomposes environment that optimized nitrous oxide emissions. Stationary combustion energy, which is energy for buildings, electricity or products, and mobile combustion. Energy sources, which is energy for transportation, also emit dangerous nitrous oxide emissions thes air, both produced by burning fossil fuels and admitting nitrous oxide as a waste product. Nitrous oxide is also produced during the production of nitric acid, used mostly to make nitrogen fertilizers and a depict acid. Thehe depict acid is used to manufacture nylon and plastics. Nitrous oxide, let like methane, is also emitted by melting permafrost. Fourth, there's Florin Ada gases. Florida gases all the on Lee completely Man made greenhouse gases in are comprised of four different types. Hydrofluorocarbons per floral carbons, sulphur hexafluoride tze and nitrogen trifle. A rides. Florida gases were created to substitute ozone depleting substances and products such as refrigerants, aerosol propellants, phone blowing agents, solvents and fire retardants. This was done after the passing of legislation known as the Montreal Protocol and efforts to protect the ozone layer. The Montreal Protocol was passed to restrict the use of ozone depleting substances, but because foreign aided gases were created as a replacement for those ozone depleting substances. The efforts have Boston to abolish their missions was compromised. The other sources of chlorinated gases are much less abundant but still important. Magnesium and aluminum manufacturing, along with the manufacturing of semiconductors, which are vital pieces for producing many electrical devices from computers to musical greeting cards, constitute most of these emissions. There are also missions from tracer gases, which are used to try to trace leakage of gases. The final source comes from the leakage in the insulation of electrical transmission equipment. Such a circuit breakers, which contained the most potent of chlorinated gases. Sulfur hexafluoride. Lastly, there is water vapor as the earth warms from other greenhouse gases, Race of evaporation increase, resulting in more water vapor in the atmosphere. This water vapor acts like a greenhouse gas and amplifies the heat of other greenhouse gases, which has led many scientists to believe that water vapor is responsible for 60% of warming. However, increased levels of water vapor have also been believed to lessen the amount of Pete there reaches Earth's surface because of increased levels of water vapor. There are more clouds being formed in the atmosphere. Clouds natural reflect light into space, which lessens the amount of heat that can reach Earth's surface. Because water vapors effect Uncle of Warming is a relatively new discovery. Scientists really aren't completely sure how much increased levels of water vapor will affect global warming in the long run. Now we are officially done with our discussion of greenhouse gases and their characteristics, sources and the solutions that have been proposed to lower emissions. If this was your first episode, I highly encourage youto also listen to the episodes before this about each greenhouse gas. I hope for all of this that you're starting to see how much of an effect the little is. Things have on our earth everything from your hamburger to your refrigerator. Ads heat to our atmosphere, and it's really, really bad to say it bluntly. We're making a massive mess. Look outside. Look at our planet. It iss suffering. If we do not change if we do not become better than what that our earth will be the one who pays our Children, we'll be the ones who pay. Future generations will look back at us one day. What will they do? Will they scoff behind the face mask they have to wear to protect them from smog? Will they cry out? Why didn't you do something? Didn't you know this would happen? Or by some miracle, will they one day look back at us and say thing? God, they acted when they could. I don't know about you, but I want my kids to look back at me and say my mom did something. It doesn't matter how small or how big or how meaningless or how meaningful you think your impact will be. Every movement begins with baby steps. You cannot climb the mountain without first approaching the base. You cannot swim the ocean. If we're too afraid to get in the water, we can make a change. We could make a lot of change just by taking small steps. If all I can get you to do after listening to these episodes is by refillable water bottle, if all I can get you to do is plan a tree, if all I can get you to do is pay a little more attention to our dying earth, then I will be able to sleep at night knowing I did something the world needs to know how much we are hurting our earth. It all starts with baby steps. It all starts with one voice, which becomes many actions, which becomes a movement which one day becomes a change, as always, if you have any questions or if there's a climate change topic you'd like me to talk about, don't forget to comment below Comma Blow or on the Instagram Post associate with this episode. Now that we're done with greenhouse gases, I have the freedom to actually do some of the topics you have questions about. So if you comin a topic for an episode, and I do an episode on it, I'll give you a shout out during the episode. And if you haven't already subscribe to this podcast and follow me on instagram at talking underscore about underscore Global underscore warming, spread the word about this channel so that more people can be informed about global warming and we could take true steps to saving our world from climate change.
