Nairobi, Kenya, 12-day United Nations Climate Change Conference is being held. Will be closed Nov. 17 This meeting was generally considered to start were more explosive report stole the limelight.
week ahead the appointment officially began, 30 October, the British government formally announced by former World Bank king economist Nicholas. Stern (Nicolas Stern) presided over the completion of the appraisal report on global warming, given the potential economy impact of the clearest picture even now:
If in the coming decades tin not take timely action, global warming, the economic and social crisis, comparative to globe battle and the first half of the 20th century have arose in the Great Depression. then, the world's GDP (gross servant product) of one-fifth are presumable to disappear.
In an interview with the Stern as economic impact of the controversy is far from over.
a excellent miracle: it is nor high neither low, and no thespian changes, is simply a absolute .
problem is that the earth is how to maintain a appropriate alive environment?
to the 19th centenary, scientists have gradually opened up its mysteries: the ultimate heat really comes from the sun, the sun brights on the earth, part of the is reflected back into space, some climate and the Earth's surface is absorbed, so that the globe has become warmer.
the same time, the Earth will heat itself to the long wag (infrared) in the manner of external radiation. However, these radiation and not all return to space. the atmosphere of carbon dioxide, methane and nitrogen oxides and other gases absorb long wag radiation, which wrapped the earth like a greenhouse as warm. These gases, collectively referred to as > thank these greenhouse gases, without it, perhaps the whole earth will become chilly than the Siberian wasteland anyhow. But the answer is, once these lofty concentrations of greenhouse gases,toronto escorts, the temperature rose to a certain amplitude, may entirely change the existing climate system, resulting in economic and social life of the muddle, even devastating.
the first such advising, maybe dating back to 1896. Nobel Prize Laureate in Chemistry, the Swedish pharmacist Arrhenius (Svante Arrhenius) that meantime each of the carbon dioxide produced by burning coal, ambition outcome in a puny addition in temperature, will go aboard long-term accumulation of a significant efficacy. If the concentration of carbon dioxide doubled, global temperatures will heave 5-6 摄氏度.
from 50's of final century, scientists increasingly concentrated in the eyes of greenhouse gases from human activities impact on the climate. cornering point occurred in 1988, the World Meteorological Organization (WMO), United Nations Environment Programme (UNEP) judged to build The second and third assessment report have been unlocked. the Fourth Assessment Report is expected to be officially loosened in 2007.
National Climate Centre chief scientist Dr. Zhang Chengyi accept the the scientific community about global warming trend has been basically approached a accordance that immediately the temperature has reached the highest point in 1000.
predict climate changes of this complicated system, there is still considerable uncertainty, but human activities are especially industrial production, vigor use and land use,toronto escorts, in which the role has also been widely accepted. a clear whistle is: Before the Industrial Revolution, cloudy carbon dioxide concentration of about two hundred and eighty millionths, and long-term reliability; and in the elapse 200 years, but increased to four hundred and thirty millionths, up by more than 50%.
Stern to accept the Taking into account some of the latest scientific evidence; in the process of completion of the report, he also has been working with the UK Met Office (Hadley Centre as Climate Prediction), IPCC climate experts have retained close contact.
To this, Many experts accept the Professor Chang (Inez Fung) on full of controversy.
report,beijing massage, if strong amounts are not taken instantly to the next century, global warming may be due to the detriment of 5% -20% of the GDP.11 2 May issue of the British authority of the technological periodical multiple districts and a sequence of scenarios that may happen an mean proportion. However, up to 20% of the GDP wastage likelihood, still makes numerous people feel has been Princeton University) economist Richard. Leo (Richard Tol) to accept the En select only the most unhappy conclusions. In appending, in assessing the shock of rising sea, it overlooks the jetty and other facilities, the role played by the conservation.
also many assumptions. Moreover, global warming is still fraught with uncertainty, controversy is the very ecology of entities.
The report likewise demanded that, if person beings absence to stabilize greenhouse gas concentrations in the level of 450-550 parts per million, that is, ensuring that air alteration does no surpass the previous human experience (ie no more than 5-6 degrees temperature change, which namely seasoned at present humans via the glacial maximum temperature alteration), then the annual investment necessitated, only 1% of global GDP .
This is apparently not an extravagant investment. Stern on br> However, many people have questioned this figure. They trust that Stern overestimate the economic impact of global warming, they also artificially underestimate the conversion from the current economic system to a ) economic The state ought have a very difficult to achieve this goal, let alone by 2050 to reach 60% -80% reduction in the amount.
some economists, energy experts told close Jiucheng global energy afford is still dependent on traditional fossil energy sources, to achieve the overall transformation, the cost can assume.
China faces greater challenges in receiving Si family, said Stern report, while only a , savants accept the machinery, the Chinese companies and government are also accessible from carbon trading to earn some proceeds.
but in the ; multinational instruments, took over as prime minister next year; then, the United Kingdom may be made in the EU a more radical policy proposals to control greenhouse gases. And with the Republicans in the fair concluded mid-term plebiscites have been setbacks, has been hard-line stance on climate change is expected to approach the United States to disconnect, accordingly joining to control greenhouse gas emissions, br> near to the administration decision-making levels in the approval of is one inevitable reality. Stern told the amplifying countries must also be made of emissions by 2050 likened with 1990,shanghai massage, an increase of no more than a 15 min.
According to UN statistics, China's per capita carbon (greenhouse gas) emissions levels, still higher than the world about one-fifth under the average, only about one-sixth of the United States. but the present situation of China's economic evolution point of view, if it were not for a big restructuring, China's per capita carbon emissions exceeded the world average is not far away. < br> 11 on 10, with visiting EU Trade Commissioner Peter Mandelson discourse in Beijing, says that in hereafter WTO negotiations, climate change may take into account elements such as the levy lower taxes. and these once implemented, obviously, would make are going through a greenhouse gas emissions, facing the policy, institutional, technical and monetary challenges, can be imagined.
State Environmental Protection Administration Center for Environmental and Economic Policy Dr. Hu Tao, director of Academic Committee to accept the pointed out that most of China's enterprises absence ample capital, but also the absence of ample technology to accomplish this transformation. He phoned something like .
1987 with an aim to depress the amount of ozone-depleting substances, and other inputs to this fund over 20 billion U.S. greenbacks; in all 189 Contracting States, 143 have reached the eruption abatement targets.
present, many formative countries have intended alike experts Foundation by the United States, Australia and other countries per capita carbon emissions funded by the Fund to purchase in the form of formative countries like China obviously difficult financially defended. you understand, to complete this economic restructuring,in fact, annual investments needed in the 200 billion -300 billion.
the technical side, it is suggested that Stern behaviour international R & D cooperation, including harmonization of standards and mart share information. long-term care almost climate change policy of the international capital Structure Committee (ICCF) Managing Director, Margo. hydrochloride (Margo Thorning), PhD, the :
