From the weather reports and the news, you may notice that the climate is so changeable recently. The changeable climate could do harm to the creatures in the world. For example, it is reported that recently because of the decreasing of the ice in north pole, the number of the north pole bears has been reduced. A picture showed a north pole bear that died from hunger and from the terrible weather. Some news also said the air pollution has increased so quickly that the environment has been greatly impacted in many big cities.
The reason for the changeable climate could be the following: At first, due to the movements of sun, the weather could be very hot in the summer in the north part of earth but extreme cold in the south part, which also brought destructive droughts and floods in different areas. Secondly, the changes of climates largely depend on human activities. Large numbers of private vehicles have produced increasing amounts of serious polluted air from CO2 cars emit and from other chemicals – all of which cause the rising of temperatures, sea level rise and reduction of land coverage. It is obvious that the changes of landscape and water levels change the environments of animals, making it hard for them to survive.
Evidence is gathering that human activities are changing the climate. This ‘climate change’ could have a huge impact on our lives. Global temperatures have risen by 0.6 degrees Celsius in the last 130 years. This rise in global temperatures leads to huge impacts on a wide range of climate related factors. Levels of carbon dioxide, methane and nitrous oxide gases are rising, mainly as a result of human activities. Carbon dioxide is being dumped in the atmosphere at an alarming rate. Since the Industrial Revolution, humans have been pumping out huge quantities of carbon dioxide, raising carbon dioxide concentrations by 30%. The burning of fossil fuels is partly responsible for this huge increase. The level of carbon dioxide emissions has been increasing over the last 130 years and the rate of increase is huge. Methane levels in the atmosphere have increased by 145% since the Industrial Revolution. This increase is a result of gas produced by livestock and paddy fields.
There are some uncertainties as to what effects a change in climate might have on the earth. To predict what might happen, we first need to start by understanding how the increase in gases such as carbon dioxide and methane affect our climate.
What might happen to the earth if subjected to a change in climate?
The changes may be:
a rise in global sea levels
a change in vegetation zones
an increase in disease levels
a change in ecosystems
Ecosystems could be affected by a change in temperature. It has been predicted that an increase in temperature would affect species composition. Scientists also believe that up to two thirds of the world’s forests would undergo major changes. Scientists believe that deserts would become hotter, and desertification would extend and become harder to reverse. Detailed studies are undertaken in the UK to see how climate change is affecting humans, agriculture, vegetation, the ozone layer, hydrology, invertebrates, marine life, forests, birds, and the freshwater environment.
All these changes could occur if we carry on polluting the atmosphere with gases. There are many things we as individuals can do to help slow down any increase in global temperatures. One way we can cut down on the amount of carbon dioxide we use is by making less car journeys. How often do you get a lift to school when you could easily have walked? Could you share a lift with a friend so only one car would need to be used? These small differences count.
There is also a particularly important topic, the car. Cars are also an important cause of pollution. It burns a lot of gasoline and emits a lot of carbon dioxide. What we can do is to use as many electric cars as possible. Electricity is a renewable energy source. We can generate electricity, solar power, and wind power. Therefore, the use of electric vehicles is also a very environmentally friendly thing. My favorite electric car brand, Tesla and Azure. I hope that more and more electric cars will appear in the future market. The current battery life and charging are very mature. The battery life of electric vehicles can reach 500KM-1000KM. It can be filled in less than an hour. I am constantly paying attention to this market because I am also a car fan.
We could also use less carbon dioxide by using better insulation in our homes. This would lessen the need to burn fossil fuels such as coal and oil that give off carbon dioxide. We could also switch to using renewable sources of energy such as wind or solar power.
For this phenomenon, everybody in the whole world should firstly, understand the importance of protect our environment. To make a peaceful earth not only for human society and other creatures. Governments should adopt some policy such as to punish the destroyer in time. Students should be educated to do some protection for environment.
To conclude, as a student, I also can contribute to the reduction of the effects of climate change. I think using products that leaves less or no carbon footprint by using efficient production can be my first step. Also, we can create student clubs and forums to organize different activities like camping, seminar, procession, cleaning projects etc. regarding important environmental issues to generate more public attention. And my major is database. The scope of this profession is very large. The Big Data is needed in many places, and we can use Big Data to fight against climate change. It’s a global issue that continues to amass potential risks day after day, and nearly all efforts to slow or stop it completely have turned up nothing useful. We need more information and time. Through the collection of continuous streams of information and data, we can extract actionable intel and insights that could further our community.
