What are the consequences of global warming?
1. More forest fires
Global warming not only makes glaciers melt, hurricanes wreak havoc, but also intensifies forest fires. In the past few decades, more forest fires have occurred in the western States of the United States, affecting a wider range. Scientists have found that the rising temperature and the premature melting of snow and ice are all related to wildfires. Due to the early melting of ice and snow, the forest area becomes drier and the drying time becomes longer, which increases the possibility of fire.
2. The historical sites were completely destroyed.
Global warming is likely to completely destroy civilization and historical sites. Rising sea levels and worse weather may destroy these irreplaceable historical sites. At present, the flood caused by global warming has destroyed the 600-year-old ancient city of Sukhothai, which was once the capital of the ancient Thai dynasty.
Step 3 "bounce" mountains
Ordinary climbers may not notice that the heights of the Alps and other mountains have experienced a slow rebound process in the past century due to the melting of snow and ice on the top of the mountain. For thousands of years, these icebergs have been squeezing the surface for a long time, resulting in the suppression of the surface. As the glaciers melt, the weight of the ground decreases and the ground slowly rebounds. Because global warming has accelerated the melting of glaciers in recent years, the rebound speed of these mountains has accelerated.
4. Faster satellites
The increase of carbon dioxide changes the density of atmospheric ionosphere, which will have a certain impact on satellites operating in this layer. Due to the rising content of carbon dioxide in the atmosphere, low-altitude carbon dioxide molecules release heat when they collide, which leads to the warming of the air. At high altitude, carbon dioxide molecules are thin, and the chances of colliding with each other are not frequent enough, so the heat radiates to the surrounding area, cooling the surrounding air (the temperature of ionospheric gas is higher than that at low altitude). As more carbon dioxide reaches the high altitude, more cooling processes occur, and the air fluidity becomes worse, so the atmosphere becomes thinner and the pull on the satellite becomes smaller, which leads to the acceleration of the satellite.
5. Change the animal gene map
As plants bloom early this year, animals that migrate according to the previous time may miss all the food. Animals that can adjust their internal biological clocks and adapt to changes early have a better chance to give birth to offspring with stronger viability, thus transmitting their own genetic information and ultimately changing the genetic map of the whole species.
6. The melting of frozen soil makes the surface uneven.
Global warming melts permafrost, causing the surface to shrink and become uneven, resulting in some pits, which have caused damage to railways, highways and houses. For high mountains, the melting of permafrost may even lead to mudslides.
7. The lake disappeared
In the past decades, 125 lakes have disappeared around the North Pole. Scientists have found that the disappearance of these lakes may be due to the melting of permafrost at the bottom of the lakes. Due to the melting of these permafrost zones, the lake water has penetrated into the soil.
8. Polar plants are alive
The melting of arctic ice has brought a bright future to arctic creatures. It is found that the concentration of chlorophyll in Arctic soil today is higher than that in ancient soil, which shows the biological prosperity in Arctic region in recent decades.
9. Animals migrate to higher ground.
From the19th century, chipmunks, mice and other animals began to migrate to high places. It is found that the reason why these animals migrate to higher places may be that their habitat environment has changed due to global warming. The change of habitat environment also threatens polar animals such as polar bears, because the ice they inhabit is slowly melting.
10. Allergy is getting worse.
Studies have shown that high carbon dioxide concentration and high temperature in the air are also one of the factors leading to allergies. Global warming makes plants bloom earlier than before, and the increase of carbon dioxide concentration will make plants produce more pollen and increase the pollen concentration in the air. Allergens come early, and the allergy season is postponed. Allergy will only get worse.
The consequences of global warming may be fresh in everyone's memory: rising temperatures, melting ice sheets and rising sea levels. However, other consequences caused by global climate change, such as increased allergies, raging forest fires and the disappearance of Arctic lakes, may be little known.
