Global Warming assignment

Global Warming assignment Words: 660

Some believe that a dramatically warming is taking place in the overall global climate a problem hat is referred to as global warming. Peg What is Global Warming and how is it formed? Global Warming is the increase of Earth’s average surface temperature due to effect of greenhouse gases, such as co from burning fossil fuels or from deforestation which trap heat that would otherwise escape from Earth. Global warming is a problem of too much CO in the atmosphere which is like a blanket trapping heat and warming the planet.

As we burn fossil fuels like coal, oil and natural gas for energy or cut down and burn forests to create pastures and plantations. Carbon accumulates and overloads our atmosphere. Certain waste management and agricultural practices makes the problem worse by releasing other potent global warming gases, such as methane and nitrous oxide. Causes and Effects of global warming? Peg The effects of global warming are strongest at the poles. Ice all over the world is melting. This includes the ice on mountain glaciers, Arctic sea ice and ice sheets covering West Antarctica and Greenland.

The melting ice increases the sea level and this causes flooding of low-lying areas. When snow and ice melt, their ability to reflect sunlight is lost, escalating global warming even further. And mean while cities like Venice are starting to sink. Small islands such as Guyana are also starting to become submerged. Weather patterns have an effect on humans. Rain is not only trouble for humans but storms damage human property. The increase in heat will increase evaporation which is why there will be more rain.

Animals and plants cannot easily adapt to increased rainfall or snowfall and many animals migrate to other areas. Plants can die as a result and this can cause an ecosystem to collapse as plants are the main source of food in an ecosystem. Droughts mean there is no water for plants o grow. Agriculture would be severely affected. The high temperatures can also cause heat-strokes and other illnesses to humans. This migration destroys ecosystems and their biodiversity. As parts of the food chain are lost from an ecosystem, the whole ecosystem can easily collapse.

Ecosystems are important to humans. Humans get food employment raw materials and pharmaceutical products from the environment. Peg Green houses gases and its sources? Many chemical compounds found in the Earth atmosphere act as greenhouse gases. These gases allow sunlight to enter the atmosphere freely. When unlighted hits the Earth surface some of it is reflected back towards space as infrared radiation. Greenhouse gases absorb this infrared radiation and trap the heat in the atmosphere.

Over time, the amount of energy sent from the sun to the Earth should be about the same as the amount of energy radiated back into space leaving the temperature of the Earth surface roughly constant. Many gases present these greenhouse properties. Some of them occur in nature like water vapor, carbon dioxide, methane, and nitrous oxide. While others are exclusively human made like gases used for aerosols. Peg How to prevent global warning? Sorting and making use of recycling bins and recycling days in your city is a great start but why not take it a step further?

Go paperless with your monthly bills and statements. If for some reason you do need to use paper, look for paper that is 100 percent post-consumer recycled paper. Be a smart consumer and look for other paper products that are also could be recycled. It has become commonplace to bring are usable bags to the supermarket or the farmer market but consider using these bags for other purposes. Many of the reusable shopping bags are very attractive with bright prints and designs. Why not use these as gift bags so the recipient can then reuse the bag himself or herself?
