"Climate Change) First, Global warming is cause by the increase in greenhouse. One natural cause is a release of methane gas from arctic tundra and wetlands. Methane is a greenhouse gas. A greenhouse gas is a gas that traps heat in the earth's atmosphere. “We cause global warming by increasing the greenhouse effect, and our greenhouse gas emissions just keep accelerating,” (John Cook “Quantifying the Consensus on Anthropogenic Global Warming in the Scientific Literature,”) Most scientists agree that planet’s temperature has risen 0.5 degree Celsius since 1900 and will continue to increase at an increasing rate.
Global Warming Global warming is an increase of the average temperature of the Earth’s atmosphere. Some of the main impacts of Global warming on Earth are on the environment, the population and animals. The effects on Earth from its habitants is causing the temperature on the Earth to rise, and creating many problems that will begin to occur in the upcoming decades. The greenhouse effect is what is causing the temperature on the Earth to rise. Greenhouse gases are chemical compounds that are found in the atmosphere.
Man-made climate change happens because we emit greenhouse gases into the Earth`s atmosphere. These gases trap or absorb the infrared radiation from the Sun. Emision of the gases have different sources, including factory fields, power plants, agriculture
Polar bears may disappear as the sea ice continues to melt. Thus, scientists intend to figure out why the global temperatures have risen, but that thus far they have not found the solution for global warming. A few scientists think global warming is natural; however, the majority of plentiful scientists think global warming is manmade because of emissions from transportation, air conditioning and
In other words, the surface of the Earth is heated up by sunlight, but this heat is not emitted into space, but rather it is kept within the atmosphere of the planet. This way, the greenhouse effect directly causes global warming. The processes that take place in the greenhouse effect are of course much more sophisticated and complex, however the initial structure is the same. Layers of Earth atmosphere serve as glass roof and walls, which let the sunlight inside, but do not let the heat outside. Now let us look deeper into what happens in the greenhouse effect, and which processes influence it in positive or negative ways.
The effects of our actions are taking a toll on us and the Earth. The sea levels are rising, ice is melting worldwide, and natural disasters are becoming more deadly. If we do not change our ways there are more problems predicted to happen including the extinction of animals, and the disappearance of coral reefs. In its 2001 report, the Intergovernmental Panel on Climate Change stated, "There is new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities." (Source 1 “Union of Concerned Scientists”) As humans we have come to rely on certain things to sustain our lifestyles.
Global Warming, What is it? Some may think it’s just the heating of the earth’s surface and some, they may not even note or care about what it is and how it is affecting us. Global warming is the gradual increase of the earth’s surface due to the greenhouse effect. Global warming justifies many climatic questions, but global warming like any other answer has abounding factors that dispenses it and outcomes as a result of the effects. Global warming as a resultant of greenhouse gases commences from the many different cycles; such as the carbon cycle and the nitrogen cycle.
Earth’s natural greenhouse effect makes life as we know it possible. However, human activities, primarily the burning of fossil fuels and clearing of forests, have intensified the natural greenhouse effect, causing global warming. Man-made emissions are leading to increased amounts of greenhouse gases in the atmosphere. The increases in greenhouse gases are trapping more of the energy radiated from earth and are likely to lead to global warming and weather extremes. The greenhouse effect can be harm to plants and animals, it has taken million of years for life to become used to the conditions on Earth.
Owing to the development of industry and the use of fossil fuels, the amount of carbon dioxide in the earth’s atmosphere has produced and the average global temperature seems to have risen. What’s more, deforestation can affect climate changes. The growing of trees and plants can absorb carbon dioxide from the atmosphere because of photosynthesis, however, deforestation lead to carbon dioxide emissions. Both of these can lead to global warming of the atmosphere. The report (UNEPWMO, 2004, P10) also pointed out, the burning of fossil fuels and deforestation are altering the composition of the atmosphere and contributing to climate change.
