Definitin: Have you noticed that it's getting warmer and warmer every year? To put it simply, that's because of air pollution. Scientists tell us that because of air pollution, the earth's heat cannot escape. This is known as global warming. If this situation is allowed to continue, it will just keep getting hotter and hotter.
Causes: Along with the success of the industrial revolution in 1750, it also marks the beginning of greenhouse gas began on Earth. Since increased machines are being invented commonly in Europe, the train, car, and tools have been globally trade, and being use. During the process of machine being commonly used, carbon dioxide gas began to increase. Since 19th century, Earth average surface temperature was increased approximately 2 degrees Fahrenheit which equal 1-degree Celsius cause by carbon dioxide gas emissions along with the industrial revolution, greenhouse gas, human activities, and other factors contributed to Earth natural resources. To change the overall cause of global warming we have infinite ways in our human decision to bring the harmful effect to beneficial effect, and we would see how global warming has brought to our Ecosystems, human activities, and our mother nature.
Consequences:
- Glaciers melt: As the glaciers melt, polar bears die of starvation and exhaustion in order to cross ice-free rivers. walruses need to rest on sea ice, because the melting of the sea ice led to a sharp decline in the living space of walrus, herds of walrus can only squeeze in a piece of ice to get a small living space, some walrus no living space and die, and even some in the search for living space when climbing to the cliff was killed alive. All these heartbreaking phenomena are really playing out at one end of the earth, which is the harm brought by global warming. So what are the effects of global warming on humans？
- Cities will be flooded by seawater: We all know that global warming is a topic of constant concern all over the world, and various countries have various regulations and measures to prevent global warming. Global warming may is a very grand problem, its harm seems do not involve us, even some people think that global warming is a hoax and humans do not need to worry about it. So today let's popularize global warming.First of all, I want to tell you that global warming is a solid fact and caused by humans. NASA maps show that the extent of Arctic sea ice is declining rapidly from 1984 to 2019. So what does global warming do to us? The biggest impact of global warming on humans is that cities will be flooded by seawater. The 2015 Paris climate agreement set a limit on future warming to 2 degrees, but under this standard, Shanghai and Guangzhou will be completely submerged. Despite the warming standards were set, the situation varies from country to country, each country needed to set its own plan to reduce carbon emissions and it was no longer mandatory. Therefore by that standard, temperatures could rise by 2.9 to 3.4 degrees by 2100, So the AR5 report said that global warming is not a problem of the future, but an urgent one. The cities in Jakarta, Indonesia, are flooding at a rate of 7 to 10 centimeters a year, with floodwaters washing away their homes. Wildfires in Australia, hurricanes on the east coast of the United States and locusts in East Africa are all direct or indirect harm caused to human beings by global warming. As Liu Cixin wrote in the Wandering Earth: Nobody cared about the disaster at first, it was just a wildfire, a drought, the extinction of a species and the disappearance of a city , until this disaster concerns everyone.For global warming, human beings at the top of the food chain have an obligation to protect the earth's ecology. Today, factories already emitted too much carbon into the atmosphere, so countries reduce carbon emissions by new energy sources and absorb it. This process is known as carbon neutrality. China is also vigorously developing new energy technologies. China's wind power generation started from scratch and overtook the United States to remain the world's top in seven years. China has set a target of carbon neutrality by 2060, which means we can't just shout slogans without taking action. We need everyone to make conscious efforts, from countries to individuals.
contrast
- Global warming is becoming a serious problem nowadays and the effect it has on our daily lives is becoming more and more obvious. From what we can see and feel, the summer is gradually getting hotter and the winter is getting colder and colder as well, it is only a matter of time before the temperature becomes unbearable for us humans.
