Climate change Global warming , the definition is the increase in the earth’s ocean and near surface temperatures. In the last decades, there have been many debates about global warming. Greenhouse gases contribute to the climate changes, greenhouses gases is carbon dioxide, but there is an ongoing debate if natural sources, such as volcanoes, and forest fires contribute to the climate changes. The United Nations Framework Convention on Climate Change (UNFCCC) created the Kyoto protocol, is an agreement among industrialized nations who have pledge to reduce their annual emission of greenhouse gasses. The kyoto protocol currently consist of over 160 nations over 55% of the worlds greenhouse gasses. The biggest contributor of the …show more content…
However, there are also clean

technology that does not emit this kind of gases, an example of a clean energy source is the wind turbine. Global warming exist because of the greenhouse effect. under normal conditions the greenhouse effect is what makes life sustainable. What happens is our sun emits solar radiation which strike the earth and causes the temperature to rise. After being absorbed by the earth, some escapes out into the space and some of it is trapped by the atmosphere and it causes the earth to heat up. The atmosphere is like an insulator it keeps the earth war at night, but the earth atmosphere insulator has become too efficient, and keeps more heat than necessary, causing the earth temperatures to rise. Researchers had identified that there is a direct relationship between the earth temperature and the presence of greenhouse gasses, such as carbon dioxide. Passenger vehicles is responsible for more 20% of the world's carbon dioxide. Deforestation has also contribute to higher greenhouse gasses, and global warming because plants take carbon dioxide through a process called photosynthesis. Other ways that are use to measure the greenhouse gases levels, are by analyzing tree rings or the glacial ice sample, current greenhouse gasses levels at the highest over 750,0000 years. Current visual evidence of global warming include , fast-melting glaciers and the ice sheets, rising sea levels, the earlier bloom of plants, the destruction
