1. 全球面临此项问题的人数正逐年增加，预计到2050年，因为气候变化

1. The number of global issues facing this increased year by year, 2050, because of climate change and the homeless population will reach 10 million people; <br>2. model built herein may know, the rate of sea level rise will increase year by year, to 2100, the sea level will rise by 0.18m to 0.59m; to 2300, the sea level will rise by 0.3 to 0.8m. Sea-level rise will lead to a small island in the Pacific and Indian oceans disappear within the next decade, resulting in a large number of climate refugees, if not effectively solve the problem of existence of climate refugees will not bring peace to the world risk factors highly; <br>3 the first issue of sea level rise caused by climate refugee problem, but in the long run, sea level rise caused by far more than that. Global warming, sea level rise caused by closely related to every people on earth. Sea-level rise will lead to deterioration of underground potable water, thereby affecting ecosystems. Therefore, in addition to solve the problem of climate refugees, we would also like to see the nature of the problem is the excessive emissions of greenhouse gases. Only control the problem of greenhouse gas emissions and environmental pollution, human beings can solve the problem fundamentally; paper suggests that reducing greenhouse gas emissions measures are: <br>to encourage the development of low-carbon economy; for higher carbon emissions of companies and enterprises to increase revenue; restrictions on vehicle travel, to encourage low-carbon travel; increased use of terrestrial ecosystem terrestrial ecosystem carbon sequestration, namely afforestation, forest restoration, high yield forest management, harvest management, forest fire prevention and pest control in order to increase carbon sequestration in forests, reducing carbon emissions; improve energy efficiency, reduce CO2 emissions and then by reducing energy consumption; energy conservation and energy efficiency, developing clean energy, reforestation, rational use of land; improved crop varieties, cultivation and selection of stress-resistant varieties, adjusting the industrial structure and layout of food, develop water-saving agriculture; strengthen water management and flood storage, water conservation, water resources development of the air, sea water desalination; improving public health infrastructure, the establishment of climate change-induced disease early warning system; strengthen the monitoring of sea level rise, the construction of the dam embankment protection.

1. The number of people facing this problem worldwide is increasing year by year, and it is expected that by 2050, 1 billion people will be homeless as a result of climate change;<br>2. From the models established herein, it can be seen that the rate of sea level rise will increase year by year, by 2100, sea levels will rise by 0.18 m to 0.59 m; Rising sea levels will lead to the disappearance of small islands in the Pacific and Indian Oceans within the next decade, creating a large number of climate refugees, and if the survival of climate refugees is not effectively addressed, it will bring dangerous and unpeaceful factors to the world;<br>3. The first problem posed by sea-level rise is the problem of climate refugees, but in the long run, sea-level rise poses far more than that. Global warming and the problems caused by rising sea levels are closely related to every earth's people. Rising sea levels will lead to the deterioration of underground drinking water, which in turn affects ecosystems. So, in addition to solving the climate refugee problem, we also have to see that the essence of the problem is excessive emissions of greenhouse gases. Only by controlling greenhouse gas emissions and environmental pollution can humanity fundamentally solve the problem;<br>Encourage the development of a low-carbon economy, increase taxes on companies and businesses with higher carbon emissions, limit motor vehicle travel, encourage low-carbon travel, and use terrestrial ecosystems to increase carbon absorption from terrestrial ecosystems, i.e. afforestation, forest restoration, rich forest management, logging management, forest fire prevention and pest control, etc., to increase forest carbon sequestration and reduce carbon emissions Improve energy efficiency, and then reduce CO2 emissions by reducing energy consumption, energy conservation and energy efficiency, development of clean energy, afforestation, rational use of land, improve crop varieties, cultivate and select anti-reversing varieties, adjust the industrial structure and layout of grain, develop water-saving agriculture, strengthen water resources management and storage, save water, develop air water resources desalination, improvement of public health infrastructure, early warning system for climate-induced diseases, strengthening monitoring of sea level rise and construction of protective dams.

1. The number of people facing this problem is increasing year by year. It is estimated that by 2050, the number of people homeless due to climate change will reach 1 billion;<br>2. Through the model built in this paper, we can know that the speed of sea level rise will increase year by year. By 2100, the sea level will rise 0.18m to 0.59m; by 2300, the sea level will rise 0.3 to 0.8m. Sea level rise will lead to the disappearance of small islands in the Pacific Ocean and the Indian Ocean in the next decade, resulting in a large number of climate refugees. If the survival problem of climate refugees can not be effectively solved, it will bring a very hidden danger to the world;<br>3. The first problem brought by sea level rise is the problem of climate refugees, but in the long run, sea level rise brings more problems than these. Global warming and sea-level rise are closely related to everyone on earth. Sea level rise will lead to the deterioration of underground drinking water, and then affect the ecosystem. Therefore, in addition to solving the problem of climate refugees, we should also see that the essence of the problem is the excessive emission of greenhouse gases. Only by controlling greenhouse gas emissions and environmental pollution, can human beings fundamentally solve the problem. This paper suggests that measures to reduce greenhouse gas emissions are as follows:<br>Encourage the development of low-carbon economy; increase taxes for companies and enterprises with high carbon emissions; restrict vehicle driving and encourage low-carbon travel; use the land ecosystem to increase carbon absorption of the land ecosystem, i.e. afforestation, forest land restoration, high-yield forest management, logging management, forest fire prevention and pest control, to increase carbon sequestration and reduce carbon emissions; improve energy efficiency, and then pass Reduce energy consumption to reduce CO2 emissions; save energy and improve energy efficiency, develop clean energy, plant trees, and use land rationally; improve crop varieties, cultivate and select stress resistant varieties, adjust grain industrial structure and layout, and develop water-saving agriculture; strengthen water resource management and storage, save water, develop air water resources and desalination; improve public health infrastructure, We should establish an early warning system for diseases caused by climate change, strengthen the monitoring of sea level rise, and build a protective dam.
