Who can tell me what's wrong with the climate now?

Global warming is the culprit of frequent extreme weather (strong typhoon, torrential rain and drought).

global climate change refers to a series of global climate changes caused by climate warming.

The reason is:

The increase of greenhouse gases in this century is irreversible. The rising temperature will melt the permafrost near the polar regions, decompose a lot of organic matter, and release more greenhouse gases. This cycle will further increase the temperature, and eventually lead to the change of ocean currents, the northward shift of subtropical high, and large-scale desertification near the Tropic of Cancer. The resulting low pressure will attract the cold air in the Arctic to move southward on a large scale and meet with the warm and humid air flow moving northward near 3C° degrees north latitude to form a large-scale cyclone. Strong typhoon and rainstorm can be formed in summer and autumn; In early spring, freezing rain can form, which freezes some countries in the northern hemisphere. Just like the American blockbuster The Day After Tomorrow.

Siberia and other high latitudes will become warm and humid, suitable for crop growth. The global arable land has increased.

curbing climate change has become an urgent task for mankind. At present, scientists have put forward two geo-engineering schemes, which need to be implemented all over the world.

in the final analysis, the power of a typhoon comes from solar energy, so just keep out the sun. The method is:

The most effective cooling method. At present, scientists have two schemes:

1 This is a problem of cooling the earth by imitating volcanic eruption.

When a large-scale volcano erupts on the earth, a large number of sulfate particles enveloped the whole earth, reflecting 7/1 of the sunlight back to outer space and cooling the earth. Now scientists want to cool the earth by spraying sulfate particles by plane.

But there are two processes that affect the climate

1. Reflecting sunlight makes the earth cool.

2 causes global acid rain.

So this method needs further demonstration.

2 A large number of reflectors are placed on the synchronous track, reflecting 7% of sunlight.

The United States has also developed a method to bury carbon deep underground, one of which is to cut down trees and then bury them deep.

Another natural method is that scientists find that the earth's magnetic field will soon reverse, and there will be a weak period of magnetic field for tens of thousands of years during the transition period, when charged particles and cosmic dust will break into the atmosphere, 5% of the sunlight will be reflected, and the Great Ice Age will come.

In addition, the iron supplement to the ocean and afforestation that we have considered before can't cool the earth, because algae and plants still release carbon dioxide after decay.

Reducing emissions can't cool down, because:

The increase of greenhouse gases is irreversible in this century. The rising temperature will melt the permafrost near the polar regions, decompose a lot of organic matter, and release more greenhouse gases. This cycle will further increase the temperature.
