What will the human world look like in 2050?

By ddzyx

Our world is getting hotter and hotter. In the next 20 years, predictions tell us that temperatures in some parts of the world will rise even higher. This is an irreversible development that is completely uncontrollable. Ecosystems around the world have stopped absorbing carbon dioxide from the atmosphere, and in general, they are emitting carbon dioxide. Oceans, forests, plants, trees and soil have absorbed half of our carbon dioxide emissions for many years.

Possible world in 2050

By 2050, there is very little left in the forest, most of the forest is either felled or swallowed by wildfires, and permanent Frozen ground is emitting greenhouse gases into the already overwhelmed atmosphere. By the end of this century, climate change may be the main driver of global biodiversity loss and changes in ecosystem services. The surface temperature of the earth is expected to rise by 2.0-6.4 degrees Celsius, which will cause more floods and droughts. Sea level will rise, and by 2100 this will be 50-70 cm. As the speed of climate change accelerates, the destruction of biodiversity worldwide will intensify.

The second turning point is the melting of the Arctic ice sheet. Summer sea ice in the Arctic no longer exists because the warming in the Arctic is more severe, 6 to 8 degrees higher than in other regions. The melting took place in this cold place. Although this is far from the most inhabited world, its effects were quickly noticed. The Great Melt is a catalyst for further global warming. White ice used to reflect the heat of the sun, but now it is gone, so dark seawater absorbs more heat, expands the quality of the seawater, and pushes the sea level higher.

More moisture in the air and higher sea surface temperatures have led to a surge in extreme hurricanes and tropical storms. Recently, coastal cities in Bangladesh, Mexico and the United States have suffered brutal infrastructure damage and extreme flooding, killing thousands and displacing millions. This situation is becoming more and more frequent now. Every day, due to rising water levels, some parts of the world must evacuate to higher ground. Every day the news will show such pictures:mothers carrying children, wading in floods, houses torn by vicious currents like mountains and rivers. News reports say that because there is nowhere to go, people live in water-to-ankle houses, their children cough and wheeze because of mold growing on the bed, insurance companies declare bankruptcy, and survivors have no resources to rebuild their lives. Contaminated water supply, sea salt intrusion and agricultural runoff are daily business. Because multiple disasters always occur simultaneously in each country, basic food and water relief can take weeks or even months to reach areas hit by extreme floods. Diseases such as malaria, dengue fever, cholera, respiratory diseases and malnutrition are rampant.

All eyes are now focused on the Antarctic ice sheet. If it disappears, it may release a lot of fresh water to the ocean, making Sea level rises above 5 meters. Cities like Miami, Shanghai, and Dhaka will become unsuitable underwater cities, and perhaps only some skyscrapers remain above the water.

Like the rising ocean, the drought and heat waves in the interior form a natural hell. The vast area suffered severe drought due to desertification, and wildlife has become a distant memory. These places can hardly sustain human life; their aquifers dried up long ago, and the groundwater was almost gone.

Inland glaciers around the world have almost disappeared, millions rely on the Himalayas, the Alps and the Andes Millions of people using glaciers to regulate water supply are in a constant state of emergency:no more snow becomes ice on the top of the mountain in winter, so spring and summer will no longer gradually melt. Now it is either heavy rain that causes flooding or long-term drought. When the equatorial belt became almost uninhabitable, the floating population of 500 million people moved north from Central America to Mexico and the United States. Others moved south to the tip of Chile and Argentina, and the same scene was staged in Europe and Asia.

The world we must create

Since 2020, we have successfully halved emissions every ten years. We are creating a world where the temperature will not exceed 1.5 degrees Celsius by 2100.

In most parts of the world, the air is humid and fresh, even in the city, it feels a lot like in the forest Walking, probably this is exactly what you are doing. The air is cleaner than before the Industrial Revolution.

First of all we have to thank the trees, they are everywhere. But although the multiplication of trees has earned us the time needed to eliminate carbon emissions, we must still relocate carbon to cope with climate change. Trees absorb carbon dioxide from the air, release oxygen, and put carbon back to where it belongs. In the soil. This of course helps reduce climate change. As more and more trees are born and cars are reduced. Every vacant lot and every dirty alley were reused and turned into a shady grove. Each roof has been transformed into a vegetable garden or flower garden. The windowless buildings that were once graffiti graffiti may be covered with verdant vines.

Rebuilding and solving the problems of urban climate change is crucial, but Further measures must be taken, which means that global rewiring efforts must go far beyond cities. The world’s forest coverage is now 50%, and agriculture has been developed to be based on trees. Perhaps by 2050, our world will be another look, look forward to it!
