Climate Change
When the Sun rays every planets in our glassy get the sunlight and one of those planets is the Earth. As we know sunlight help to warm our atmosphere. When the Earth go around the Sun all the places in our atmosphere get the sunlight. That supports most life form or survive in this planet especially plants. As the rays enter to our atmosphere most continue down to the Earth’s surface. When the rays hit any substance (soil, water surface, etc) those rays release much of their energy as heat. Some of this heat radiates back into space. So, what actually caused the climate change?
The carbon dioxide is the primary issue that causes the climate change. The fossil fuels that left from the animals and plants in the ancient time. The products from fossil fuels, such as gasoline and diesel fuel that uses for the engine’s power to drive cars, airplanes and ships. Human uses is a large impacts that causes the climate change. When they use those fuels to run a machine it’ll create carbon dioxide then release back to our atmosphere. Carbon dioxide, methane and water vapor are the gases that retain heat, so those gases are the part that helps to warm our planet too. The gases do this by absorbing the heat and radiate back to Earth’s surface. Those gases nicknamed is “greenhouse gases”. Carbon dioxide in the atmosphere have been increased 30 percents from the last 650,000 years to now. Carbon dioxide rise up “is essentially and completely due of burning fuels” Susan Solomon says.
People have further increased the levels of greenhouse gases by changing the landscape. Plants help our atmosphere to have less carbon by take the carbon dioxide to make the food in a process called photosynthesis. But by cutting down trees and forests for farmland and other human uses, more carbon dioxide enters the atmosphere. “We’ve always had some greenhouse gases in the atmosphere” Solomon says. “But because we’ve burned a lot of fossil fuels and deforested, we’ve increased the amount of greenhouse gases and as a result have changed the temperature of the planet.”
Earth is warming and sea levels are rising. There’s more carbon dioxide in the air, so Arctic ice is melting faster than at any time throughout the history. As more people are burning fossil fuels like coal and oil for energy it releases more carbon dioxide in the air. Indeed, more carbon dioxide is enters the more the planet warms. If burning fossil fuels doesn’t slow, the long-term climate impacts and effect could be. During that time the global warming even higher than what the scientists had expect. Snow and ice reflect sunlight back into space but as the snow and ice melt, sunlight can now reach to the water surface and ground. As this surplus heat rises, the air temperature even more higher that causes more and more snow and ice melt. Carbon dioxide is a huge affects to the global warming and this type of rapid impacts is called a “fast feedback”.
We have some sunlight and greenhouse gases that keeps us warm. When people use the fossil fuels to run the machines and burning coal and fuels for the energy. That creates a lot of carbon dioxide and increases the amount of greenhouse gases and causes the climate change. Plant is a part that helps to reduce the carbon dioxide in the air by the process called photosynthesis. But by cutting down trees and forests for farmland and other human uses. We lost a significant help from plants that usually help reducing the carbon dioxide but after deforested it involves more carbon dioxide enters our atmosphere. As a result form now to the future our planet will face a big crisis. The temperature is hot, so the organism or the living things can die and some places on Earth will lack of water.
