10 reasons to fear global warming

10. Redrawing the map of the Earth

[RICH_HTML type = imageset] [/ RICH_HTML] About 2% of the world's water reserves are stored in the form of ice. If it melts, the sea level will rise by about 70 meters. According to some estimates, by 2050 the Arctic will be free of ice in summer. Not only megalopolises like New York and Miami can be under water, but also whole countries, for example, the Philippines.

9. The threat of hunger

[RICH_HTML type = imageset] [/ RICH_HTML] By 2050, the world's population will exceed 9 billion, and 70% more food will be needed than now. Feeding everyone will be very difficult. More than half of the calories people in the world get from corn, wheat, soy and rice. These crops are expected to fall due to global warming and environmental pollution.

8. Carbon dioxide leak in the Arctic

[RICH_HTML type = imageset] [/ RICH_HTML] Carbon dioxide traps heat, enhancing the greenhouse effect. The Arctic acts as a giant repository of global carbon reserves - up to 1850 billion tons of carbon dioxide is stored in its frozen bowels. For comparison, as a result of human activities since 1850, only 350 billion tons of carbon dioxide were released into the atmosphere. With climate warming in the Arctic, permafrost is melting, releasing carbon dioxide and thus warming the planet.

7. Ocean oxidation

[RICH_HTML type = imageset] [/ RICH_HTML] About a third of human carbon dioxide is absorbed by the world's oceans, which leads to its oxidation. Since the beginning of the industrial revolution, the acidity of seawater has increased by 30%, and it seems that the situation will deteriorate significantly by the end of this century. It is unlikely that an increased pH level has a beneficial effect on aquatic inhabitants. Most of all, mollusks and corals suffer from oxidation.

6. Mass extinction

[RICH_HTML type = imageset] [/ RICH_HTML] Extinction of animal and plant species is a natural evolutionary process. But sometimes in a short period of time, most living organisms disappear from the face of the Earth. The planet has already experienced five mass extinctions, and scientists have found a relationship between disasters and climate change. Some experts are sure that the sixth mass extinction begins on the planet. Amphibians turned out to be the most vulnerable - global warming has already been found guilty of the disappearance of the orange toad and harlequin frog.

5. Weather disasters

[RICH_HTML type = imageset] [/ RICH_HTML] A study by the International Panel of Experts on Climate Change showed the relationship between global warming and weather disasters. Droughts, abnormal heat, floods and hurricanes became more intense and turned into an ordinary phenomenon. Each year, the elements claim an average of about 106, 000 thousand lives and cost $ 184 billion.

4. A more cruel world

[RICH_HTML type = imageset] [/ RICH_HTML] Many regions will become uninhabitable due to floods and droughts. In search of new lands and resources, the settlers will face the local inhabitants, which will almost inevitably lead to war. Perhaps the process has already begun: one of the causes of the war in Syria is called the drought caused by global warming.

3. Stop the global pipeline

[RICH_HTML type = imageset] [/ RICH_HTML] Thermohaline circulation, also called the ocean conveyor, is a process of slow movement of water around the earth. Warm surface waters gradually move north and inward, to the bottom of the ocean, while cold food-rich currents are directed south and up. Every second, 45 million cubic meters of water moves from the bottom of the ocean to its surface. Occasionally (possibly due to climate change), the conveyor stops. Nowadays, this would lead to a temperature drop of 10 degrees in the North Atlantic, crop failures in Europe and the collapse of the ocean ecosystem.

2. Billion expenses

[RICH_HTML type = imageset] [/ RICH_HTML] Annually, climate change takes up to 400 thousand human lives and removes more than $ 1.2 trillion from the global economy. In the future, losses will only grow.

1. Earth Hacking

[RICH_HTML type = imageset] [/ RICH_HTML] Geoengineering, known as "Earth hacking, " offers different ways to take control of global warming. One idea is to release a huge amount of sulfur into the atmosphere, simulating a powerful volcanic eruption. Sulfur particles trap sunlight, thereby cooling the planet. The concentration of carbon from this, of course, will not decrease, but its effect will be neutralized. True, it is not yet known what the consequences of clogging the atmosphere with ashes will be. No matter how worse it gets!
