资料学——通过小波分析认识传统气候资料处理中问题
方差校正的影响
著名的英格兰中部近200多年的逐日气温序列（CET）是由3个邻近 站资料重构起来的。1882年前主要是一个站的资料，1883年后主 要是3站平均。序列创建者发现1882年前序列方差系统性地偏大， 于是作了方差校正。 下图可见，年均温序列看不出异常。但经小波分析，可见DV在 1882-83年间出现跃变。这对我们定义气候极值分析气候趋势造 成严重影响。

重视区域异常天气事件（气候极值） 从逐日资料提取气候极值信息 从分布概念出发定义逐日序列极值频率指数
Zwiers and Kharin 1998： GCM模拟逐日输出分析
GLM视每个“天气”值为某种气候分布总体中抽取 的样本。通过最大似然回归确定最符合所有样 本的分布（包括确定自回归规律以及分布参数 随时间、地点和各种可能气候因子的变化）； 通过Monte Carlo法产生大量模拟样本，从中判 断气候分布及极值随各种可能原因而发生的变 化。
气温：全球气温将升高。从现在起到本世纪末，人类 将面临史无前例的气温上升。就本世纪而言，较乐观 的预测是全球气温将升高1.4摄氏度，最悲观的设想则 认为，全球气温将上升近6摄氏度。 海洋：海平面将升高。在本世纪内，海平面将可 能升高20厘米至80厘米。原因是气候变暖导致海水膨 胀，冰川和海上浮冰层融化(北极浮冰层厚度50年来减 薄了40%)。在格陵兰，自1988年以来，冰川融化速度 加快，已提高了2倍。

全球变暖英语作文
全球变暖英语作文英文回答：Global warming is a pressing issue that posessignificant threats to our planet and its inhabitants. It refers to the long-term increase in Earth's average surface temperature due to the accumulation of greenhouse gases, primarily carbon dioxide, in the atmosphere.Human activities, particularly the burning of fossil fuels such as coal, oil, and gas, release large amounts of carbon dioxide into the atmosphere. These gases trap heat, leading to a rise in global temperatures. Other greenhouse gases include methane, nitrous oxide, and fluorinated gases.The consequences of global warming are far-reaching and include:Rising sea levels: As the temperature rises, polar ice caps and glaciers melt, causing sea levels to rise. Thisposes significant risks to coastal populations and ecosystems.Extreme weather events: Global warming intensifies extreme weather events such as hurricanes, heat waves, floods, and droughts. These events can cause widespread damage, infrastructure loss, and human suffering.Ocean acidification: As carbon dioxide dissolves in the oceans, it decreases the pH level, making the water more acidic. This process harms marine life and damages vital ecosystems such as coral reefs.Biodiversity loss: Rising temperatures and changing precipitation patterns disrupt habitats, leading to a decline in biodiversity.Addressing global warming requires a comprehensive global effort to reduce greenhouse gas emissions. This includes:Transitioning to renewable energy sources: Replacingfossil fuels with clean energy sources such as solar, wind, and hydropower can significantly reduce carbon emissions.Improving energy efficiency: Buildings, transportation, and industries can be made more energy-efficient, reducing the amount of energy needed and, therefore, greenhouse gas emissions.Reforestation and forest conservation: Forests absorb carbon dioxide from the atmosphere, making reforestationand forest conservation crucial strategies for mitigating climate change.International cooperation: Global solutions require collaboration between nations to set emission reduction targets, share technologies, and provide financial supportto developing countries.Individual actions can also contribute to mitigating global warming:Conserving energy: Simple steps such as turning offlights when leaving a room, using energy-efficient appliances, and reducing driving can reduce carbon footprint.Choosing sustainable products: Opting for products with a smaller carbon footprint, such as those made from recycled materials, helps reduce greenhouse gas emissions.Supporting renewable energy: Advocating for renewable energy policies and investing in clean energy companies can accelerate the transition to a low-carbon future.Addressing global warming is essential for the well-being of our planet and future generations. Urgent actionis needed to reduce greenhouse gas emissions, adapt to climate change impacts, and ensure a sustainable future for all.中文回答：全球变暖。
全球变暖(英语)--global-warming
in sea levels worldwide
Scientists predict an increase in sea levels worldwide due to the melting of two massive ice sheets in Antarctica and Greenland, especially on the East coast of the US. However, many nations around the world will experience the effects of rising sea , which could displace millions of people.
Increase in usage of chemical fertilizers on croplands
Carbon dioxide emissions from fossil fuel burning power plants
Every day, more electric gadgets flood the market, and without widespread alternative energy sources, we are highly dependent on burning coal for our personal and commercial electrical supply.
Deforestation , especially tropical forests for wood, pulp, and farmland
The use of forests for fuel is one cause of deforestation. Forests remove and store carbon dioxide from the atmosphere, and this deforestation releases large amounts of carbon, as well as reducing the amount of carbon capture on the planet.

Disappearance of coral reefs
A report on coral reefs from WWF says that in a worst case scenario, coral populations will collapse by 2100 due to increased temperatures and ocean acidification . The 'bleaching' of corals from small but prolonged rises in sea temperature is a severe danger for ocean ecosystems, and many other species in the oceans rely on coral reefs for their survival.
Methane emissions from animals , agriculture such as rice paddies, and from Arctic seabeds
Methane is another extremely potent greenhouse gas, ranking right behind CO2.When organic matter is broken down by bacteria under oxygen-starved conditions as in rice paddies, methane is produced .
Global Warming Effects: A Top 5 List
Rise in sea levels worldwide More killer storms Massive crop failures Widespread extinction of species Disappearance of coral reefs

高分英语作文1：global warmingIn recent years, global warming has become a hot issue of people's concern. It is caused by serious air pollution. With the increasingly serious environmental pollution, global temperature rises sharply, and disasters such as drought, flood and glacier melting also follow.Therefore, we need to protect our earth and fight against it. We should start from small things and make contributions to protect our home offer.中文翻译：近年来，全球变暖已成为人们关注的热点问题，它是由于严重的空气污染造成的，随着环境污染的日益严重，全球气温急剧上升，干旱、洪水和冰川融化等灾害也随之而来，因此，我们需要保护我们的地球并与之抗争我们应该从小事做起，为保护我们的家园做出贡献。
万能作文模板2：全球变暖Many people think that human activities cause the earth's temperature to rise. They say that global warming will have terrible consequences for our environment, such as drought and flood. What should the government do to help prevent global warming? Give your advice and reasons.The earth's temperature is changing rapidly, so thereare many climate changes, such as heat waves, droughts and floods. Scientists believe that this is human activity As a result, if governments don't take action to help prevent global warming, it could be a disaster. They can act in three ways: supporting research, laws and the public aware of the situation first.s can support research. For example, they should encourage companies to develop less polluting cars. They should also support alternative energy sources for wind and water Instead of oil and coal, they should organize meetings to discuss the impact of greenhouse gas emissions and possible solutions.Second, they should enact laws to limit the amount of greenhouse gases that companies emit. Private companies should be rewarded for complying with these laws, and they should be punished for creating pollution. Finally, everyone is affected by global warming.Therefore, the government should involve individuals in the problem-solving process, which is very important to encourage families to use more efficient light bulbs or less hot water to save energy as much as possible. They should also encourage the public to recycle, which is mandatory for everyone. Another way to save energy is through the public transport .The government should spend money on public transport to make it as easy as possible for the public to summarize energy conservation. Obviously, the government can do a lot to prevent global warming. They should involve companies, support scientists and encourage individuals to protect the earth.中文翻译：许多人认为人类活动导致地球温度升高，他们说全球变暖将对我们的环境造成可怕的后果，例如旱灾和水灾应该做些什么来帮助防止全球变暖给你的建议给出理由地球温度正在迅速变化，因此出现了很多气候变化，如热浪、干旱和洪水科学家认为这是人类活动的结果，如果不采取行动来帮助防止全球变暖，这可能会成为一场灾难他们可以通过三种方式采取行动：支持研究、制定法律和让公众首先了解情况，可以支持研究，例如，他们应该鼓励公司开发污染更少的汽车，他们还应该支持风能和水的替代能源，而不是石油和煤炭，他们应该组织会议讨论温室气体排放的影响和可能的解决方案第二，他们应该制定法律公司排放温室气体的数量公司应该因为遵守这些法律而受到奖励，他们也应该因为制造污染而受到惩罚。

Global WarmingIn the past, scientists have been skeptical of blaming increasingtemperatures on global warming. As we head into future ventures of technology and ingenuity, the science community has steadily stepped on board with the Environmental Protection Agency and other believers in global warming to do something about it. Like never before, scientists are seeing growth rates of increased climate change.Melting polar ice-caps, the collapse of vegetation and wildlife, and violent surges of hurricanes more rampant in the past are all concerning reasons to understand how climate change can affect so many facets on planet earth. Global warming doesn’t just mean the earth’s getting warmer. Global warming’s massive impact on social, economic, and physical health are areas for great distress.过去，科学家一直怀疑将温度升高归咎于全球变暖。
全球变暖现象英文作文
全球变暖现象英文作文Global warming is a serious issue that is affecting the entire planet. The rise in temperature is causing glaciersto melt and sea levels to rise, which is a major concernfor coastal areas.The increase in greenhouse gases, such as carbondioxide and methane, is trapping heat in the atmosphere and causing the Earth's temperature to rise. This is leading to more frequent and severe weather events, such as hurricanes, droughts, and heatwaves.The impact of global warming is not just limited to the environment, but also has serious implications for human health. The rise in temperature is leading to the spread of diseases and the deterioration of air quality, which is putting people at risk.One of the major contributors to global warming is the burning of fossil fuels for energy. This releases largeamounts of carbon dioxide into the atmosphere, which is a key driver of the greenhouse effect.In order to address the issue of global warming, it is important for individuals, communities, and governments to take action. This includes reducing energy consumption, transitioning to renewable energy sources, and implementing policies to limit greenhouse gas emissions.The effects of global warming are already being felt, and it is crucial that we take immediate and decisiveaction to mitigate its impact. Otherwise, the consequences for the planet and future generations could be catastrophic.。
