What is global warming?
Global warming is the process of the earth's atmosphere heating up. (The atmosphere is the air that covers our planet like a blanket.) Over the last 100 years, the average temperature of earth's atmosphere has gone up 1° Fahrenheit. The weather has not changed exactly the same way in every area of the planet. But, scientists think that the rise in average temperature is already affecting the earth's climate.
What causes global warming?
Global warming is caused by human activities , because of cutting down trees , producing more trash , and polluting the environment are some of the reasons that the temperature has gone up. Many scientists believe that the biggest causes of global warming are new human technologies that release greenhouse gases into the atmosphere.
What is the effect of global warming?
With more heat trapped on Earth, the planet will become warmer, which means the weather all over Earth will change. For example, summers will get hotter, and winters too. This may seem a good idea, but the conditions we are living in are perfect for life, and a large rise in temperature could be terrible for us and for any other living thing on Earth.
Many animals and plants may not be able to cope with these changes and could die. This could cause the loss of some animal and plant species in certain areas of the world or everywhere on Earth.
In other parts of the world, the effects will be different, some places will become drier and others will be wetter. Although most areas will be warmer, some areas will become cooler. There may be many storms, floods and drought, but we do not know which areas of the world will be affected.
Why are greenhouse gases a problem today?
Greenhouse effect is carbon dioxide , nitrogen oxide and methane that keeps the earth warm.
The greenhouse effect is not new. Carbon dioxide, nitrous oxide and methane have been keeping the e
Today, most scientists are pretty sure that the rising temperature can't be blamed on nature. Ever since the industrial revolution in the 1700s, humans have relied on machines for daily life. And many of those machines (like cars) give off, or emit, a lot of greenhouse gases. An increase in the release of greenhouse gases from human activities is throwing nature off balance.
How is global warming affecting the world?
As the climate increase the seal level has risen to 8 inches around the world , many areas is disappearing underwater. It also cause weather problems caused by pollution in the atmosphere. Like some areas have more rains other had bigger storms. If the warms gets worser , plants and animal would be extinct. Because of storms and flood .
Ways to prevent global warming:
Turn off the lights when you leave a room. Use fluorescent bulbs in your room. Wait until you have a lot of clothes to wash before using the washing machine. Don’t use the machine for one item just because it’s your favorite shirt.Take shorter showers. Heating water uses energy and Plant a tree.
