What impact will global warming have on the earth?

Global warming will bring complex potential impacts on the earth and human beings, both positive and negative.

Positive effects With the increase of temperature, sub-polar regions may be more suitable for human habitation; Under appropriate conditions, higher carbon dioxide concentration can promote photosynthesis, make plants have higher carbon fixation rate, and lead to the increase of plant growth, that is, the yield-increasing effect of carbon dioxide.

The negative impact of global warming on human activities will be even greater and far-reaching. Due to the influence of climate warming, the summit of Mount Everest has dropped by 1.3 meters.

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.

Due to the emission of greenhouse gases from the land, the temperature in the mainland is rising, and the temperature difference with the ocean is decreasing, which leads to the recent slow air flow and the smog that can't be blown away in a short time, which leads to the increase of smog weather in many cities and affects 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.

Extended data:

The greenhouse effect has been working since the formation of the earth. If there is no greenhouse effect, the surface of the earth will be extremely cold, the temperature will drop to MINUS 20℃, the ocean will freeze and life will not form. Humans emit a lot of greenhouse gases into the atmosphere by burning fossil fuels, which leads to the greenhouse effect and the rapid change of the earth's climate.

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

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