What are the consequences of climate warming?

1. Ecology First of all, global warming leads to sea level rise and precipitation redistribution, which changes the current world climate pattern; Secondly, global warming affects and destroys the biological chain and food chain, bringing more serious natural consequences. For example, there is a migratory bird that flies from Australia to the northeast of China every year for the summer. However, due to global warming, the temperature in the northeast of China rises and the summer is prolonged, so the time for this bird to leave the northeast is correspondingly warmer, and the time for returning to the northeast is correspondingly delayed. As a result, a pest eaten by this migratory bird flooded and a large forest was destroyed. In addition, related environmental problems.

2. Politically limiting carbon dioxide emissions is equivalent to limiting energy consumption, which will have a restrictive impact on all countries in the world. Whether developing countries reduce emissions or developed countries reduce emissions has become the focus of discussion. The greenhouse gas emissions in developing countries are increasing, and the problem of "emission reduction" after 20 13 will inevitably focus on developing countries. Scientific problems about preventing global warming will inevitably lead to "emission reduction"

3. Climate global warming has increased the precipitation in Chinese mainland, especially in the middle and high latitudes, and reduced the precipitation in some areas such as Africa. In some areas, the frequency and intensity of extreme weather and climate events (El Nino, drought, flood, thunderstorm, hail, storm, high temperature weather and sandstorm, etc.). ) have increased.

4. With the global temperature rising, the amount of water vapor evaporated in the ocean increases greatly, which intensifies the warming phenomenon. The reduction of the total heat capacity of the ocean can restrain global warming. In addition, the plankton community in the ocean is the real culprit, because the ocean releases excessive carbon dioxide into the atmosphere.

Global warming of crops has both advantages and disadvantages for the growth of crops. First, global temperature changes directly affect the global water cycle, causing droughts or floods in some areas, resulting in reduced crop production. Excessive temperature is not conducive to seed growth. Second, the increase of precipitation will actively promote crop growth, especially in arid areas. The increase of carbon dioxide content with global warming will also promote crop photosynthesis, thus increasing yield.

6. Human Health (1) Global warming directly leads to superhigh temperature, heart disease and various respiratory diseases in some areas in summer, and many people die every year, especially newborns and the elderly. (2) Global warming leads to the increase of ozone concentration. Ozone at low altitude is a very dangerous pollutant, which will destroy human lung tissue and cause asthma or other lung diseases. (3) Global warming.

Extended data:

Global warming is a phenomenon related to nature, which is due to the continuous accumulation of greenhouse effect, resulting in the imbalance of energy absorbed and discharged by the geo-atmospheric system, and the continuous accumulation of energy in the geo-atmospheric system, leading to rising temperature and global warming.

Because people burn fossil fuels, such as oil and coal. Or cutting down and burning down forests will produce a lot of carbon dioxide, that is, greenhouse gases, which have a strong permeability to visible light emitted by the sun, a strong absorption to long-wave radiation emitted by the earth, and a strong absorption of infrared radiation from the ground, leading to an increase in the temperature of the earth, that is, the greenhouse effect. Global warming will redistribute global precipitation, melt glaciers and frozen soil and raise sea level, which will not only endanger the balance of natural ecosystems, but also threaten human survival.

On the other hand, due to the greenhouse gas emissions from the land, the temperature in the mainland rises and the temperature difference with the ocean becomes smaller. Recently, the airflow has slowed down, and the smog can't be blown away in a short time, which has led to an increase in smog weather in many cities, affecting human health. Measures such as car restrictions and production suspension have only short-term and local effects, and cannot fundamentally change climate warming and smog pollution.
