There are four causes of global warming

There are many causes of global warming, and they can be summarized as follows:

1.Factors of population growth.

2.Atmospheric environmental pollution factors.

3.Factors for the deterioration of the marine ecological environment.

4.Land erosion, desertification and other destructive factors.

5.Factors for the sharp decline of forest resources.

6.Acid rain hazards.

7.Toxic waste pollution factors.

8. Changes in the periodic orbit of the Earth.

9. Emissions of greenhouse gases.

10. Destruction of the ozone layer.

There are many factors that affect global warming, whether it is the sun, carbon dioxide, or some movement in the earth's interior, which are the main reasons for the formation of global warming.

The main cause of global warming is that human beings have used a large amount of fossil fuels (such as coal, oil, etc.) for nearly a century, emitting a large amount of CO2 and other greenhouse gases. These greenhouse gases contribute to global warming.

Global warming will redistribute global precipitation, melt glaciers and permafrost, and rise in sea levels, which will not only jeopardize the balance of natural ecosystems, but also threaten the survival of human beings.

On the other hand, due to the increase in the temperature of the continent caused by terrestrial greenhouse gas emissions, the temperature difference between the continent and the ocean has become smaller, which has caused the air flow to slow down, and the haze cannot be blown away in a short time, resulting in an increase in haze weather in many cities, affecting human health.

There are many harms of global warming, such as melting glaciers, rising sea levels, and the disappearance of some coastal cities; The heat energy generated by the rising temperature will provide huge kinetic energy to the air and the ocean, resulting in large, or even super-large typhoons, hurricanes, tsunamis and other disasters.

1. Heat energy from rising temperatures.

The heat energy brought about by the rising temperature will provide huge kinetic energy to the air and ocean, resulting in large, even super-large typhoons, hurricanes, tsunamis and other disasters. Every year, more and more disasters are being struck and faced, and the number of lives and money lost is increasing and becoming more and more unacceptable.

Second, it leads to a large loss of land moisture.

Not only wildfires in forests, but also in cities, will be very frequent. The fire is relentless, and our home will be in danger 24 hours a day. 24 hours a day, which means that there is a possibility of a fire even at night. See Canadian wildfires.

3. Raise sea levels.

The rise of temperature, the melting of glaciers and the rise of sea level have caused the loss of ecological groups such as coastal tidal wetlands, mangroves and coral reefs, coastal erosion, seawater intrusion into coastal underground freshwater layers, and salinization of coastal land, resulting in the imbalance of the natural ecological environment of coasts, estuaries and bays, and bringing disasters to the ecological environment of coastal zones.
