Meteorology magazine points out that the Earth has 15 climatic tipping points, and 9 of them have been or are being breached. Once the critical point is breached, the earth's ecology will fall into an irreversible state.
The 9 tipping points are:
Arctic sea ice, Greenland ice sheet, northern foliage forest, permafrost, Atlantic ocean trending inversion circulation, Amazon rainforest, warm water coral, Southwest Antarctic ice sheet, parts of Southeast Antarctica.
These tipping points cover almost the entire planet, from Antarctica to the Arctic Ocean, from the Amazon rainforest to australia's Great Barrier Reef.
The Arctic is already ready to wear short sleeves, and the impressive images of reporters reporting in the Arctic wearing short sleeves mean that arctic sea ice and the Greenland ice sheet are worrying.
It has also been reported that the Switz Glacier, the largest glacier in Antarctica, will collapse within 3 years.
Looking closely, this year's "plum rain" season in the middle and lower reaches of the Yangtze River has become a "no rain" season, and the water surface of Poyang Lake has partially dried up between January.
In the perennially arid desert area, there is a flow of water.
High global temperatures mean that natural disasters such as floods and droughts are frequent and intensify.
Because high temperatures mean that the evaporation efficiency of surface water is high, the evaporated area will be dry.
For high-altitude water vapor, sharp evaporation also means that water vapor condenses sharply into rain, which causes water to evaporate quickly, and rainfall periods and regions will also be concentrated, and then form a torrent.
If the temperature is not high, the earth's water cycle is a slow release mode, and the high temperature means that the water cycle will switch to "motion mode".
This is bound to trigger other chain reactions in nature and human society.
Some people worry that the evaporation of water will cause groundwater holes, causing some crust plates to stress imbalance, which will trigger earthquakes.
There are fears that widespread droughts will trigger a food crisis because the dominant factor in food production is nature, unlike industrial goods, which are technology-led and can be increased through technology or overtime.
Food, on the other hand, can only be grown naturally under existing technology.
There are also people who are worried about the safety of some large human buildings, because cement will expand under continuous high temperatures, which will endanger safety if it exceeds the design limit, so high temperatures are also a test for human buildings.
Some of the cement pavements have collapsed and warped due to the high temperature.
I thought that 2020 was already the worst year, but I didn't expect that 2022 would be worse.
I hope that the high temperature will pass as soon as possible, so that the temperature of the earth will return to normal as soon as possible.
In many places, the seedlings have dried up, and grain is the basic stability of the entire human society, and if the harvest fails continuously, this basic will not be stable.
To cherish grain, it is still necessary for families in the countryside to conditionally repair the granaries, and it is still necessary to save some grain.
