What is global warming?
Global warming is the rise in temperature of the earth’s atmosphere.
What causes global warming?
Many things cause global warming. One thing that causes global warming is electrical pollution. Electricity causes pollution in many ways, some worse than others. In most cases, fossil fuels are burned to create electricity. Fossil fuels are made of dead plants and animals. Some examples of fossil fuels are oil and petroleum. Many pollutants (chemicals that pollute the air, water, and land) are sent into the air when fossil fuels are burned. Some of these chemicals are called greenhouse gasses.
We use these sources of energy much more than the sources that give off less pollution. Petroleum, one of the sources of energy, is used a lot. It is used for transportation, making electricity, and many other things. Although this source of energy gives off a lot of pollution, it is used for 38% of the United States’ energy.
Effects of global warming
1. Spread of disease As northern countries warm, disease carrying insects migrate north, bringing plague and disease with them.
2. Warmer waters and more hurricanes As the temperature of oceans rises, so will the probability of more frequent and stronger hurricanes.

3. . Increased probability and intensity of droughts and heat waves Although some areas of Earth will become wetter due to global warming, other areas will suffer serious droughts and heat waves
4. Polar ice caps melting The ice caps melting will result to 4 major issues:
First, it will raise sea levels.There are 7 million cubic miles is frozen in polar ice caps. According to the National Snow and Ice Data Center, if all glaciers melted today the seas would rise about 70m. Luckily, that’s not going to happen all in one go! But sea levels will rise.
Second, melting ice caps will throw the global ecosystem out of balance. The ice caps are fresh water, and when they melt they will desalinate the ocean, or in plain English – make it less salty. The desalinization of the gulf current will “screw up” ocean currents, which regulate temperatures. The stream shutdown or irregularity would cool the area around north-east America and Western Europe. Luckily, that will slow some of the other effects of global warming in that area!
Third, temperature rises and changing landscapes in the artic circle will endanger several species of animals. Only the most adaptable will survive.
Fourth, global warming could snowball with the ice caps gone. Ice caps are white, and reflect sunlight, much of which is relected back into space, further cooling Earth. If the ice caps melt, the only reflector is the ocean. Darker colors absorb sunlight, further warming the Earth.
How to prevent global warming :
-People should reduce the usage of electrical appliances which emits greenhouse gases.
-Follow RRR-Reduce, Reuse, Recycle.
-Trees absorb a large amount of carbon dioxide – instead of cutting them down – plant them
-Usage of green power prevents 300 kg of carbon dioxide to be emitted into the atmosphere. (The electricity obtained from the renewable resources like wind and water is called green power.)
-Insulation of the ceiling of a house and power saving
-People should use only energy efficient appliances.
-Consumption of organic food should be increased
