Global warming is defined as a gradual increase in temperature in the earth’s atmosphere. This means that the temperature on earth is rising. This is caused by there being too much carbon dioxide in the air. Car exhausts, aeroplanes, ships, and homes, schools, offices and factories energy also help cause it. When animals and humans breathe, they produce more carbon dioxide, contributing to the large amount of carbon dioxide in the air. Deforestation also plays a big part in global warming. When forests and trees are removed, it creates more space for carbon dioxide in the air. Plants also absorb carbon dioxide, so the fewer trees and plants we have, the more carbon dioxide we will have in our atmosphere.
How will global warming affect our environment over time? How does it affect it now?
The ozone layer is thinning very, very slowly. Scientists expect that if we do things a little better, the ozone layer should recover by 2065. Since the 1800's, the average world temperature has risen 0.6 degrees Celsius. Scientists predict that the average temperature will rise 5.6 degrees by 2100. Scientists and meteorologists have predicted that heat waves and hurricanes will become longer, more intense, and more frequent. We will have devastating floods and harsh droughts.
Glaciers and polar ice sheets are also melting with the rise of temperature. This is causing sea levels to rise, so some coastlines will become submerged.
Some species and plants will have difficulty surviving in the heat. Some harmful, disease-carrying species will also be able to come into places that were too cold for them before. Mosquitoes with malaria and yellow fever will be able to come into places they couldn’t. Tick season will last longer, causing Lyme disease, and rocky mountain spotted fever. Too much heat can be dangerous, even fatal to humans - especially for the elderly and the very young.
Will global warming affect people over time, or will our bodies just get used to it? Does it affect our health?
Global warming will most certainly affect our health in many ways. Disease-carrying species will be able to come into places that were too cold for them before. Mosquitoes carrying malaria and yellow fever will come into places they couldn’t. Tick season will last longer, causing more people to be diagnosed with Lyme disease and rocky mountain spotted fever. Too much heat can be dangerous; even fatal to humans - especially for the elderly and young children.
Global warming will also invoke dramatic changes in the weather - we will endure long, devastating droughts, heat waves, rain, flooding, and hurricanes. These weather conditions would be very bad for our health. Droughts will cause a shortage in food and water. Heat waves will cause the human body to get too hot, which could be fatal. If we have too much rain and flooding, we could be forced indoors, or even worse - forced out of our homes. Hurricanes are also extremely dangerous.
A new study also found that higher temperatures can worsen heart health. Too much heat can easily cause you to have a heart attack.
Allergies will also worsen with rising temperatures. Plants are flowering earlier in the year, and total pollen production is increasing. And a recent study in Italy showed that not only people were having worse allergies, more people were becoming sensitive to pollen.
Is global warming a big issue? How/why? Do people know what it is?
Global warming isn’t an issue now, but it will be in the future. Global warming could cause lots of problems for people, animals, and the environment.
61.4% of the Marama Team knew what global warming was, and 29.5% do not know what it is. 9.2% had a fair idea, but weren’t completely sure. 72.2% of people thought global warming was a big issue, 8.3% of people thought it wasn’t, and 19.6% of people weren’t sure. When I asked them why they thought that, they weren’t really sure.
How can global warming be prevented? What can we change in our everyday lives to help prevent it?
Global warming can be prevented in lots of different ways. The more plants, oceans and trees we have, the less carbon dioxide there will be in the air. Plants and trees can help clean the air of carbon dioxide. We can use solar panels and wind turbines to as a cleaner, more sustainable energy source. Scientists are working on a new car with a hydrogen engine that produces clean water, instead of carbon dioxide. They are also trying to create cars that are powered by cleaner fuels.
These are things that will take a bit of time and effort to fix/change, but there are also some things we can easily change in our everyday lives. Instead of driving a car, walk or bike. When you are finished using appliances or computers, remember to turn them off. Reuse or recycle paper, plastic and metal. If we all continue to do all of these things, we can all help stop global warming.
