global warming and how it affects climate change

The video talks about global warming and how it affects climate change. Oceanographer Josh Willis sheds light on how billions of tonnes of carbon dioxide and other greenhouse gases are emitted to the atmosphere leading to global warming. The greenhouse gases in the atmosphere cause extra heat on earth. The extra heat is supposed to go out of space, but it remains in the atmosphere. The trapped heat, therefore, warms the planet. The trapped heat on earth also affects the oceans. Willis further argues that most of the trapped heat on earth, which is about 80 to 90 percent goes to the oceans. The reason for this is that the ocean can absorb 1000 times the heat as the atmosphere. It can achieve this without changing much of its temperature. The ocean can achieve the high absorption of heat through its high heat capacity. The video consequently portrays a demonstration of the high heat capacity characteristic of the ocean in comparison to the low heat capacity of the atmosphere through an experiment. Willis places a lighter representing the sun near a balloon filled with air, which represents the atmosphere. After a short time, the balloon bursts confirming the fact that the atmosphere has a low heat capacity. In this sense, air does not absorb heat fast enough hence causing the lighter to melt the balloon. He places the same lighter under a balloon filled with water representing the ocean, and nothing happens for a long time. The water in the balloon absorbs heat fast enough to prevent the heat from melting the balloon. The second experiment confirms that the ocean has a high heat capacity and usually absorbs most of the heat in the atmosphere caused by global warming. As a consequence, the ocean is absorbing a lot of heat that is in the atmosphere. It achieves this due to its high heat capacity. Therefore the video urges us to understand the problem we are facing due to global warming. There is a lot that we can do to reduce global warming. Most of the activities that we engage in usually use some energy mainly produced by burning fossil fuels. Burning fossil fuels releases carbon dioxide in the atmosphere. The video urges us to engage in activities like turning off the lights when we leave a room, taking a bike ride instead of using a car, powering down computers once in a while, among others, to avoid contributing to more emission of greenhouses. The video, therefore, is very informative as it provides information on the sources of greenhouse gases that cause global warming, the effects of global warming as well as the ways we could adopt to reduce the emission of greenhouse gases to the atmosphere. The information that the video shares have backing from research carried out by scientists like NASA. In this sense, the information from the video is verifiable and reliable. Additionally, a live demonstration conducted in the video is enough proof that various aspects of our lives will be severely affected by climate change. Aquatic life, that is, the plans, animals, and all the other organisms that live in water, are the most affected by global warming. As could be seen from the video, water has a high heat capacity; hence the water bodies absorb most of the heat on earth. The continual absorption of heat consequently affects aquatic life. The video, therefore, provides a great insight into the problems associated with global warming.
