China Meteorological News reporter Shi Yizhuo reported in April 13th, the United Nations Intergovernmental Panel on climate change (IPCC) in Germany Berlin released its fifth assessment report of working group third report. The report shows, although more and more policies to mitigate climate change, but the global greenhouse gas emissions have risen to the level of hitherto unknown; only through major institutional and technological transformation, to achieve the global temperature increase at 2 ℃ target.
called the "climate change 2014: mitigation of climate change," the report pointed out that, by adopting various technical measures and behavior change, there may be an average global temperature rise limit beyond 2 ℃ pre industrial levels. However, only through major institutional and technological change, they are more Cheap Bulls Jerseys likely to control global warming in the range of the threshold.
Preparation of235 authors from 57 countries and 38 in the report editor. The authors evaluated 1 thousand copies of the scientific literature, and the scientific literature about 1200 scenarios were analyzed. It consists of 31 modes of team development around the world, according to the different degree of ambition to explore conditions and affecting prerequisite various slow path of the economy, technology and system.
IPCC said, during the period from 2000 to 2010 emissions growth rate during the thirty years before any ten years faster, but the scene display, the global average temperature rise limit at 2 ℃ is possible, which means that compared with 2010, by Cheap NBA Shorts the middle of this century to will be reduced by 40% to 70% of global greenhouse gases, to the century to reduce to nearly zero.
according to the report, in order to realize the stabilization of atmospheric concentrations of greenhouse gases, require the use of energy effectively, and the energy production, transportation, construction, industry, land use and various human residential industry emission reduction. In addition, the electric power production emissions reduced to near zero is the common feature to ambitious emission reduction scenarios.
land is 2 ℃ target is another important part of. Slow deforestation and forest have been planted to halt or even reverse the increase due to deforestation emissions. Through afforestation, land can be used for the absorption of carbon dioxide in the atmosphere. This can also be obtained by biomass power and carbon capture and storage technology combination to achieve. However, so far this combination has not been characterized by Cheap Pacers Jerseys large scale, perennial stored in underground carbon dioxide to face all kinds of challenges, and the need for management of land competition risks aggravating. The multifunctional use of land, can reduce the risk of.
Thethird working group co chairman of the Eden Hofer said: "there are many different paths can achieve the future does not exceed the stated goal of 2 ℃. All of these path requires a Cheap Magic Jerseys lot of investment. To avoid further delay slow and limit the costs associated with using Cheap NBA All Star Jerseys a variety of techniques."
up to now, the IPCC fifth assessment report three working group reports were published, along with a comprehensive report will be published in October this year, will constitute the IPCC fifth assessment report on climate change.
