xinhuanet.com Berlin 13 April report (reporter Tang Zhiqiang) the United Nations Intergovernmental Panel on climate change (IPCC) 13 in the German Berlin said in a report, global greenhouse gas emissions are accelerated, in order to control global warming, must make greater efforts than now.
Thereport is part of a IPCC fifth assessment of climate change, attention to the mitigation of climate change. The report says, from 2000 to 2010, man-made greenhouse gas emissions an average annual increase of 2.2%, higher than the previous 30 year average annual growth rate of 1.3%.
if the climate change mitigation efforts Cheap jerseys remain at current levels, not to take more greenhouse gas emission reduction measures, to 2100, global average temperatures will than before the industrial revolution high 3.7 to 4.8 degrees Celsius, and Cheap NCAA jerseys the current global warming to control the temperature 2 degrees celsius.
Thereport said, to achieve control objectives, 2 degrees Celsius by 2050, global greenhouse gas emissions should be lower in 2010 than the 40% to 70%; to Cheap soccer jerseys 2100, greenhouse gas emissions should be close to zero.
IPCC fifth assessment report on climate change third co chairman of the working group responsible for the report, ·otter; Eden Hofer said, 2 degrees Celsius target can be achieved through different paths, each path requires a lot of input, but the action delay would make climate change mitigation cost.
Thereport points out, to climate change mitigation effect depends on the energy supply, industrial, transportation, construction, land use, city planning and other different fields. Anthropogenic greenhouse gas emissions from 2000 to 2010, 47% from the field cheap jerseys from china of energy supply, 30% from industry, 11% from transportation.
report that, over the past 10 years, the main driving factors of greenhouse gas emissions growth is the increase in energy demand and rising global fuel structure in the proportion of coal. To control global warming, global energy supply system should change on a large scale, to increase wind, solar, hydro and other renewable energy and nuclear energy and other low-carbon and zero carbon energy use ratio, out no fossil energy power generation application form of carbon capture and storage technology. The global energy supply sector in 2040 to 2070 should realize the carbon dioxide emissions 90% below the level in 2010, and ultimately to achieve zero emissions.
in the industrial field, can make use of innovation and technology upgrading, improve efficiency in the use of energy from industrial processes, Cheap NHL Jerseys and the recycling of materials and products and recycling, reduce the emission of greenhouse gases. In addition, the cooperation between different industries, different companies, sharing facilities, information, resources also contributes to the whole industry emission reduction.
in the field of transportation, through technical means to improve transportation energy use efficiency; promote hydrogen, bio fuel vehicles, electric vehicles and other low carbon vehicles; increase investment in infrastructure, construction of a high-speed rail network, reduce the short flight demand; with the help of city planning, to encourage cycling, walking and public transport. >
