Global Warming

Global Warming

Global warming is the gradual increase in the earths overall temperature in the atmosphere which is created from the green house gases which is made up of increased levels of carbon dioxide, CFC's and other polutions. Photo 1: Pictures factories and power plants creating huge amounts of carbion dioxide or other gases that affect the environment. In Photo 3 it shows the processon which global warming takes place and how green house gases allow to much of the suns rays to enter the earth and not rebound back out into the atmoshere.

Effects of Global Warming on Earth

Glaciers shrinking in Antarctica which will cause the sea level to increase height, potentially drowning small islands.Ice on rivers and lakes is breaking up earlier than usual. This would have affect on animals as the polar bear for example needs the ice to hunt prey.Plant and animal ranges shifted from usual habitat as they are unable to sustain on there natural habitat because it has changed to rapidly due to global warming. The things that may have changed would be the food sources, climate and recources. Sea levels and the earths temperature is rising which has disasterous affects on snow and ice regions. This then affects the animals natural habits and habitats. It allows more sun to travel to the earth which can also affect humans. Skin cancers and strokes can be due to too much heat off sun.Photo 2 pictured on the right shows the affects that global warming can play on the earth. Which include more wildfires, droughts and tropical cyclones.

Ways to reduce Global Warming

Two ways that you can help reduce the greenhouse affect are informing others about the problem and trying to cut down on the amount of pollution you are releasing into the earths atmoshere. Ways to do this could be switching to renewable energy sources such as wind farming, solar, wave, geothermal and a few others. Perhaps that the way to solve this problem would to be to use all these different renewable energy sources around the world.

Deforestation and burning of fossil fuels

Deforestation is the destruction of forests and dense plant areas and is a large issue due to the important role the plants play in the environment. The plants breathe in carbon dioxide which is realised in many different ways including when we inhale air. Carbon dioxide is one of the main threats to global warming. The plants use a special process called photosynthesis which converts carbon dioxide into oxygen. If forests continue to rapidly be destroyed then the balance of carbion dioxide and oxygen will dramatically contribute to the green house gas affects. The burning of fossil fuels release one of the largest amounts of carbon dioxide emissions which are apart of the Greenhouse gases.

The Kyoto Protocol

The Kyoto protocol is an international treaty that many countries signed to reduce greenhouse gas emissions based on the premise that global warming exists and man-made CO2 emissions have caused it. The treaty is run by the United Nations Framework Convetion on Climate Change (UNFCCC). It is important when considering global warming because it is one of the only things that will be able to make a massive impact on reducing the global warming problem. The Kyoto Protocol was adopted in Kyoto, Japan in 1997. There are currently 192 state parties participationg in this treaty. The state party are trying to move towards renewable energy sources and NOT fossil fuels. The Kyoto protocol commits parties by setting internationally binding emission reduction targets. The Kyoto portocol is an intelligent and efficient way of reducing global warming.

Government Initiative Reducing Greenhouse Effect

Photo 3

One government initiative in Australia that is aimed at reducing the Greenhouse effect is the United Nations Framework Convention on Climate change [UNFCCC]. The UNFCCC is the main global forum aimed at reducing the effects of Climate Change. The UNFCCC started in March of 1994 and now has 195 members which all meet annually at the UNFCCC conference of the parties [COP]. The ultimate objective of the UNFCCC is to and i quote " stabalize greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic [human induced] interferece with the the climate system" [UNFCCC, Article 2]. Australia plays an active role in the international negotiations. Photo 4 is an example of the symbols whgich represent the UNFCCC.
