Answer 1

Iceberg melt, the sea rises, the temperature rise, ecological damage : : the greenhouse effect brought about by global warming consequences has unmistakably appeared in front of the world. Meteorologists found, according to the monitoring data for the past two years, the atmospheric concentration of carbon dioxide a rapid rise significantly exceeded the original records. Experts worry that, if left uncorrected, the greenhouse effect will become more serious , the pace of global warming will continue to accelerate. Monaluoya Meteorological Station located in Hawaii a volcanic cost as much as 3600 metres, from half a century ago to monitor atmospheric CO2 concentrations. According to the monitoring results in the initial 30 years, with an average annual atmospheric CO2 concentration 1PPM (1PPM to millionth) of growth. With coal, fuel oil and other use of large quantities of carbon dioxide concentration has risen, in the past 20 years the average annual increase 1.5PPM, in the past 10 years the average rate of increase as high as 1.8PPM. And the 2002 and 2003, this increase is achieved 2PPM above. March results of the monitoring showed that the average concentration of atmospheric carbon dioxide has reached 379PPM, up 3PPM year ago, a record high. This year 74-year-old meteorologists Kiel said that two consecutive years of the carbon dioxide content of the air over 2PPM growth is a noteworthy phenomenon. Perhaps this, as before, is a random natural phenomenon, but it also may be human nature to lose control of the signs. Many meteorologists are worried that the past two years the rate increased atmospheric carbon dioxide content means that in the next few years, the pace of climate warming will reach out to the stage. In addition, the scientists are puzzled that, with rising levels of atmospheric carbon dioxide, the greenhouse gas, natural absorption reduced. Therefore scientists are concerned that the data may indicate that the rapid rise of nature's capacity to absorb greenhouse gases in the air rapidly weakening, which in turn means the Earth will be faster warming. However, the meteorological analysis scientists said there is a need to continue to observe the phenomenon, now would be premature to make a long-term conclusions. Beijing Normal University meteorology and climatology, Dr. Xie pointed out that at present 31 global climate models scientists use to predict the next 100 years of global climate change, the global average surface temperature results in the next 100 years will be increased by 1.4 degrees -5.8 degrees, This is probably the fastest warming in the past 10,000 years. carbon dioxide and aerosols into the common role of scholars predict our next 100 years the temperature will continue to rise, the scope of future warming will also increase. "awareness of global climate change is a vital element of what the Earth's climate system and the radiation energy situation," CMB Liuzhenkun explain the solar radiation reaching the Earth's climate system is the Earth energy "income". Its part by direct reflection back to space, Another part of the climate system "absorption" later in the form of infrared radiation emissions back to space. Whether the solar radiation reaching the Earth changes or reflection or infrared radiation from the Earth changes will trigger the Earth climate change. Scholars believe that human activities are a catalyst for global warming process. Liuzhenkun noted that the current global average temperature change, carbon dioxide levels and changes are almost simultaneous rise from the start of the industrial revolution, a dramatic increase in CO2 concentration, although the plant photosynthesis absorb a large part of carbon dioxide, part of the ocean was dissolved carbon dioxide into calcium carbonate and fixed, but the air is gradually increased carbon dioxide content. By the greenhouse effect, melting of glaciers, the Earth into two age; Tornadoes, tsunamis raging, more dry desert; El Nino phenomenon will be more serious, global warming : : Our Earth is a warming trend, the scientific community is concerned about the long-topic. Recently, an American scholar in journals using climate models proof of global warming trend, and some European scholars have proposed a new theory that the Earth is warming, but on the contrary. Climate models proof of global warming In November the "natural" magazine article entitled "Global climate change on the hydrological impact" papers, the U.S. scholars in 12 meteorological models that of the 20th century to global climate change trends : warming and predict the 21st century global hydrological changes, and further pointed out that if the global water cycle system was mixed, it will promote global warming. As a team lead figures Federated Lane (Milly) of water for human health, economic development, ecological effects, geophysical and other areas have a great effect. Focusing on river runoff and water add trend analysis found 12 existing climate models can accurately explain the changes in the 20th century. Federated Lane meteorological changes that the 20th century has been volcanic activity, sunspot, atmospheric circulation, etc. factors, and therefore must be included in climate models, the choice of atmospheric and ocean circulation and the greenhouse effect. 12 climate models through this analysis, the scientists believe that the 20th century warming is a significant climate change, The CCSM3 climate system model by Buerde (Boulder), the National Center for Atmospheric Research (NCAR) announced last year, it was known as the common mode of three versions of the climate system. This is the world's leading general circulation climate models one, including the impact of volcanic eruptions on the temperature distribution, also includes the impact of sea-ice drift absorb sunlight. This model has been used in the initial results show : If community to continue to emit large quantities of carbon dioxide to the atmosphere, global temperatures could rise sharply. Opposition : the global cooling However, faced with global warming thesis that there are many objections. In August this year, Russian Academy of Sciences Institute of Physics and the Russian hydrometeorological bureau of the Central Meteorological Station altitude researchers through years of study, proposed a new theory to explain. The theory that cosmic rays stream in the process of global temperature changes play a more important role, instead of the general view that the greenhouse gas emissions. Based on the observations of cosmic rays, the 21st century global temperatures will not rise, but started slowly. Researchers believe that the cosmic rays from distant space constantly exposed to the upper atmosphere and interact with the atmosphere after a sub-ray flow, flow-ray equally affected by the solar activity. Cosmic rays in the stratosphere and troposphere will ionizing air to air a conductive nature, eventually lead to the Earth charged. and the electric field accelerated the formation of the Earth charge air is not charged particulates contrast to the lighter ion adsorption into the water vapour gathered at the center, which would lead to an increase in the number of tropospheric lower the map. Cloud amount not only affect the flow of solar changes in the atmosphere also affect the temperature changes. Researchers believe that the 20th century temperature rise is due to the Earth's cosmic ray intensity gradually declined, the troposphere And stratosphere in terms of reducing air conductive, thunderstorm activity declined map coverage areas narrowed. And the cosmic ray intensity has 200 years cyclical changes in the 21st century, projected to cosmic rays on Earth will increase, the temperature will drop. And from the United Kingdom and the Netherlands on December 1 meteorologists in the British "Guardian" wrote an article pointing out that, the impact will also render Stream temperatures drop. According to data provided by the experts, since 1957, Mexico Stream has been reduced by 30% This will lead to an average temperature of the European continent in the next 10 years will decline 10 meridian east C. Netherlands Meteorological researchers Bas love Kehate (BasEickhout) that this result is due to Arctic ice melt, the large influx of freshwater hot water gradually cut exchange process, thereby interfering with the formation of Mexico Stream. and the slow pace of ocean current movements in the United Kingdom and the Nordic region's average temperature will drop a few degrees, the scientists have more far-reaching impact detection out.

Answer 2

climate change has a significant effect(气候变化的重大影响）
By the second half of the century, wheat, rice, corn, etc. Some of the main crop yields will drop up to 37 percent. Experts warned that the next 20 to 50 years of agricultural production will also be a serious impact on climate change if we did not take measures to climate change will be a direct threat to the safety of Chinese food.
After friendly consultations, the Chinese and British governments decided to cooperate on climate change impact on Chinese agriculture. Chinese Ministry of Science and Technology and the Environment, Food and Rural Affairs today and tomorrow in Beijing jointly held a "climate change impact of a seminar on China's agriculture", the two officials, scientists, nearly 100 people attending the meeting, co-analysis of global climate change on China's future Agricultural development of the likely impact of Find the energy sector to deal with the impacts of climate change solution.
Officials of the Ministry of Science and Technology said that the Chinese government attaches great importance to the climate change problem, formulated and promulgated a series of global climate conducive to the protection of policies and measures, achieved remarkable results. China has ratified the Kyoto Protocol and the Protocol to the entry into force of optimism. China will also be in accordance with national conditions and strictly carrying out the Framework Convention on Climate Change and the Kyoto Protocol, developing countries should be under the obligation to work closely with other countries, particularly developed countries work together to protect the climate. At the same time, by controlling population growth, improving energy efficiency and to carry out large-scale afforestation activities, China's greenhouse gas emissions effectively slowed down.
The official said that China attaches great importance to climate change science and technology research, in advance of global climate change research has made the deployment of the system in the future will be to explore the mechanism of climate change science, research and development and to adapt to climate change mitigation technologies and methods, Research on climate change a national strategy and policy action, such as three areas, focusing on support for climate change research.
The supply of food security in the world on climate change one of the most concern. British officials said the British Government attaches great importance to cooperation with China and is willing to work together to promote the protection of global climate and promote sustainable development, and hoped that the entry into force of the Kyoto Protocol at an early date.
China is a large agricultural country, the climate change impact on agricultural production, and the United Kingdom and its impact on climate change research in the world's leading level. To this end, China and the United Kingdom Ministry of Science and Technology for Environment, Food and Rural Affairs in July 2001 in Beijing to carry out the signing of climate change science and technology research agreements on bilateral cooperation, and since the September 2001 start the implementation of climate change on China The impact of agricultural research. After the two scientists to work together to implement the project over the past two years, in the future climate change scenarios predict the impact of climate change on agriculture and the simulation of the future of China's social / economic scenario analysis, land-use change, climate change and adapt to evaluate the combined effects of Measures such areas as fruitful.

To everyone on our planet,

Over the past years, floods, droughts, landslides, and dust-storms have frequented our planet, the only habitat of human beings. Several days ago, tsunami(海啸) has swept the Southeast Asia, which has caused enormous damage. All these have sounded an alarm to human beings.

The destruction which is caused by human beings has aroused people’s concern all over the world. If we pay no heed to the present destructive human activities, our planet will become of tomb instead of cozy home. What’s more, we should realize that only from our planet can we obtain our sheltering, food, cloth and so forth.

Counter-measures must be taken to curb the destruction caused by human beings. Most importantly, laws must be established to punish those who are involved in destructive conducts.

Sincerely Yours
