Effects of Global Warming Effects and Causes of Global Warming

1. Global warming has caused a large number of glaciers to melt gradually, resulting in a rise in sea level that threatens coastal areas. The cold season will be shortened and the warm and hot seasons will be lengthened due to global warming. Global warming will lead to more and more extreme weather such as droughts and typhoons. Global warming will lead to an increase in the concentration of ozone in low altitudes, affecting human health.

2. As people burn fossil fuels, such as oil, coal, etc., or cut down forests and burn them will produce a large amount of carbon dioxide, i.e., greenhouse gases, these greenhouse gases have a high degree of transmittance of visible radiation from the sun, while the Earth's emission of long-wave radiation has a high degree of absorbency, can strongly absorb the infrared in the terrestrial radiation, resulting in an increase in the Earth's temperature, that is, the Greenhouse effect. Global warming will make global precipitation redistribution, glaciers and permafrost melting, sea level rise, etc., not only jeopardize the balance of the natural ecosystem, but also threaten the survival of human beings.

3. On the other hand, due to the land-based greenhouse gas emissions caused by the continent's temperature rise, the temperature difference with the ocean becomes smaller, which in turn causes the air flow to slow down, the haze can not be blown away for a short period of time, resulting in an increase in hazy weather in many cities, affecting human health. Measures such as car restrictions and production moratoriums have only short-term and localized effects, and cannot fundamentally change climate warming and haze pollution.
