By 2030, people will face severe drought

It is estimated that although the remaining greening area is still relatively large, the Amazon forest has been pushed to its limit. The phenomenon of forest death will occur.

With a small area, the forest is unable to produce enough water vapor to form rain clouds, leading to the fact that the most damaged patches of forest will gradually transform into seasonal dry forest, which then becomes grassland. vast resource. Just like that, the more the forest dies, the less rainfall it receives. The less rainfall, the more dead forest area.

As a result, the process of drying up in the entire Amazon basin will take place at a very fast rate with terrifying devastation, leading to a dramatic decline in biodiversity here.

The Amazon rainforest is home to about 10% of the world's known species, so local extinctions there can trigger an 'extinction domino effect' on entire ecosystems. thai. All wild populations are severely affected, individuals in the population will face more difficulties in feeding and finding mates.

Wildfires in the Amazon.

Many species of plants and animals with the potential to be processed into new medicines, foods and other industrial applications will disappear before humans even know they exist. But the price we pay is much deeper and more direct than that.

We will lose a series of environmental services that the Amazon forest has always provided for people. As the trunks die, the forest soil that was once anchored in their roots is washed away into the river, leading to more dense flooding. 30 million people, including about 3 million Aboriginal people, could be forced out of the watershed.

Variations in air humidity are also likely to lead to a decline in rainfall over much of South America, causing water shortages in megacities. Ironically, the drought will hit the very same farmland created by deforestation, having a profound effect on food production in Brazil, Peru, Bolivia and Paraguay.

During the Holocene (a geological epoch), the most important environmental service that the Amazon forest provided to humans was its ability to trap more than 100 billion tons of carbon in the forests here. However, the number of forest fires in each dry season increases the amount of carbon returned to the atmosphere.

At the same time, the loss of trees reduces the photosynthesis capacity of forests, causing the amount of carbon absorbed each year to also decrease. As a result, the atmosphere must receive more carbon dioxide, the rate of global warming evidently increases accordingly.

Around the 2030s, at the ends of the Earth, the Arctic Ocean is predicted to experience a completely ice-free summer for the first time, causing the Arctic to expand. Even areas of perennial sea ice made up of thick layers of ice stacked on top of each other, sheltered in fjords, cannot withstand the warming temperatures. They start to dissolve into water. As a result, the algae forests that cling to the surface beneath the ice sheets are washed into the ocean, affecting the entire Arctic food chain.

In addition, the white color of the ice helps to reflect the Sun's radiation back into space, so as the amount of ice on Earth melts year by year, the planet's surface becomes less 'white', resulting in reflectiveness. light diminishes, accelerating the rate of global warming. The Arctic has now lost its ability to cool the planet.
