Causes and Effects of Global Warming

Global warming, those are the two words that people everywhere around the globe are mentioning. What is really global warming? Global warming is the notable rising of average temperatures in Earth’s atmosphere and the rise of sea levels in various coastal spots of the planet due to ice caps melting and making water excesses. Now, scientists are making researches, and they are predicting that in the future years, temperatures are likely to increase even more , but how much more is very difficult to predict, because greenhouse gas emissions, the gases that are in part responsible for global warming, can be emitted in different amounts, so we don’t really know how much there is going to be.

But, what is really causing global warming? Burning of fossil fuel and land clearing are just two of the many activities that release greenhouse gases, which were mentioned earlier. There are many other causes, like the natural causes for example. In the artic tundra and wetlands, methane gas is emitted, and methane gas is a greenhouse gas, and they are gases that trap the heat inside the atmosphere, not letting it out. Another natural cause of global warming is that there is a climate cycle, where climate varies, that changes every 40,000 years. Man-made causes are the most responsible causes for global warming. Pollution is one of the main causes. Gases emitted in factories really harm the environment. When oil and coal mining takes place, methane gas is escaped. Population increases, and so does global warming, why is that? Well, as you know, as population increases, more food the Earth needs, and farms may provide part of that food. As more farms are made, more animals grow, and manure lets out some methane into the air. Cars are responsible too. Like you know, cars let out lots of harmful gases, and now, there are thousands of billions of millions of cars running around the streets of every city, and letting out more gases than ever before, and on top of that, now some people own more than one car, making even more pollution. Another reason for global warming is the cutting of trees. Trees convert harmful gases into oxygen that we can use. As more trees are being cut down, less gases are turned into oxygen, so those gases make the holes in the atmosphere.

The effects of global warming are the ones we really need to be worried about. Here in Cartagena we are suffering from one, rising sea levels. Because we live in the coast, at sea level, there have been floods in he streets because way up in north pole, the atmosphere is way thinner, and the gases are making a hole in the ozone layer up there, and the ice is melting, making more water, so here, there is more water too, and we are literally sinking. Another effect is diseases that are spread. Dry areas are now being more humid, and in some places that humidity attracts mosquitoes. Mosquitoes are spreading diseases from one place to another, making more people sick. The amount of floods are now increasing, and the moment in which they will happen are unpredictable, and that is a big issue.
