Temperatures average global surface on Earth has increased by 0.74 ± 0:18 ° C (1.33 ± 0:32 ° F) during the last hundred years. Intergovernmental Panel on Climate Change (IPCC) concluded that "most of the increase in average temperature worldwide since the mid-20 century to the most likely caused by increased gas-concentrations of greenhouse gases due to human activities" [1] through the greenhouse effect. This basic conclusion has been raised by at least 30 scientific and academic bodies, including all the national science academies from the G8 countries. However, there are still some scientists who do not agree with some conclusions that the IPCC.
Climate models that project as a reference by the IPCC indicates the global surface temperature will rise 1.1 to 6.4 ° C (2.0 to 11.5 ° F) between 1990 and 2100. [1] The difference is due to the number estimated by the use of different scenarios on emissions of the gas - greenhouse gases in the future, and models of climate sensitivity that is different. Although most research focused on the period up to 2100, the increase in home heating and the sea water is estimated to continue for more than a thousand years, although the level of emissions of greenhouse gases have been stable. [1] This reflects the large heat capacity of the oceans.
Increasing global temperature is predicted to cause changes such as increasing sea surface water, increasing the intensity of extreme weather phenomena, [2] and change the number and pattern presipitasi. Effects of global warming, which is terpengaruhnya other agricultural products, the loss of glacier, and the extinction of various species of animals.
Some things are still dubious of Sciences is the estimated amount of warming that will occur in the future, and how warming and the changes that occur will vary from one region to other areas. Until now, there was still political and public debate in the world about what, if any, action should be taken to reduce or reverse the warming more information or to adapt to the consequences of. Most states in the world have signed and ratified the Kyoto Protocol, which led to the reduction of gas emissions, greenhouse gases.
Global warming (global warming)
Global Warming temperatures are increasing the average atmosphere, sea and land Earth. Global warming is caused by them were "Greenhouse Effect" or that we know with greenhouse gases. Greenhouse gases caused by the increase in the concentration of gas carbon dioxide (CO2) and other gases in the atmosphere. Increase the concentration of CO2 gas was caused by increased burning of fuel oil (fuel), coal and other organic fuel that exceeds the capacity of vegetation and sea to mengabsorbsinya.
The term greenhouse effect, taken from the planting methods used by farmers in the region are climate (the country has four seasons). The farmers used to plant vegetables or flowers in the greenhouse to keep the room temperature stays warm. Why use glass materials that clear? Because of the nature of material that can tertembus sun. From the incoming light, will dipantulkan back by the object / surface in a glass house, when dipantulkan ray is changed into heat energy in the form of infrared rays, more energy is trapped in a glass house. Likewise one of the functions of the earth's atmosphere as the greenhouse. As a simple Illustration about the warming occurrence of the Global please CLICK HERE
To prevent and reduce emissions of carbon dioxide gas, greenhouse gases and encourage the birth of the Kyoto Protocol. Negotiated in Kyoto Japan in December 1997, opened for signing 16 March 1998 and closed on 15 March 1999. This agreement takes effect on 16 February 2005, after formal ratification by Russia on 18 November 2004.
Up to 23 October 2007 are 179 countries that ratified the Kyoto Protocol, the list of countries you can see here. There are four countries that have signed but not ratified the Kyoto protocol, namely, Australia (not interested ratified), Monaco, the United States is the largest producing greenhouse gases is also not interested to meratifikasinya, and the rest Kazakstan. But after the recent Australia meratifikasinya towards the climate change conference in Bali, the United States live alone as a major industrial countries that have not meratifikasinya. Other countries that have not provided the reaction is Afghanistan, Andorra, Brunei, Rep. Central Africa, Chad, Comoros Island, Iraq, Taiwan, the Sahrawi Arab Democratic Republic, San Marino, Somalia, Tajikistan, Timor-Leste, Tonga, Turkey, Vatican, and Zimbabwe.
