Is Global Warming that serious?

Short - YES, even a slight average temperature rise can cause dramatic transformation.
We have only understood climate change as an effect on the natural environment. But climate change creates urgent human rights problems, and will continue to cause them. This is a disaster for mankind. Climate change widens and exacerbates existing inequality. The adverse effects will grow over time, posing a clear threat to current and future generations.
Ninety-seven percent of climate scientists agree that most of global warming is caused by humans. As such, an overwhelming consensus has already been formed on humanity's responsibility for warming.
The biggest cause of global warming is the use of fossil fuels such as coal, gas, and oil. This increases the concentration of greenhouse gases in the atmosphere, such as carbon dioxide. Reclamation for agriculture is also one of the reasons for increasing the average temperature of the Earth. Scientists now believe that the link between greenhouse gases and global warming is as clear as the link between cigarettes and lung cancer.
The economic damage caused by climate change is increasing every year. Last year alone in the United States alone, Hurricane Aida caused 90 trillion won in damage, 12 trillion won in western forest fires, and more than 10 trillion won in economic damage due to drought. In particular, economic damage caused by climate change causes chain damage, such as job losses and reduced food production in addition to primary damage.
By 2025, the annual loss from climate change will reach 2,000 trillion won, and if it goes to the worst-case scenario where it cannot respond, the economic damage will be 3 trillion won and 6,000 trillion won in 2075. That's about 5% of the world's GDP. At the time, 76% of the respondents predicted that climate change would cause economic damage every year, reducing global economic growth. In particular, it was expected that underdeveloped countries and poor people would suffer the most.
Why we focus on Global Warming
It is the polar animals that are directly affected by global warming. When the ice in the Arctic or Antarctic melts due to global warming, the animals living here lose their homes. For example, polar bears need sea ice, the ice that covers the sea, to live. Polar bears usually eat seals or sea lions on sea ice and mate on sea ice. And even when traveling a long distance, it uses sea ice on the sea. So scientists predict that polar bears will go extinct in the near future. Seals living in the Arctic are also destined to be polar bears because they live using sea ice.
Coral reefs become unbearable even if the temperature rises by just 3 degrees. This is because phytoplankton, which nourishes and gives life to coral reefs, leaves. This causes a whitening phenomenon in which coral reefs turn white. Bleached corals can survive, but they lose colour and are exposed to malnutrition and disease. Over the past 30 years, more than a quarter of coral reefs have disappeared. If coral reefs, the home of more than 4,000 fish, disappear, the marine ecosystem will be in serious danger.
Climate change is weakening as the amount of "nitrogen," a key nutrient that plants need, decreases, according to a study. The researchers warned that weakening trees could not only harm the nutrition of animals that use them as their staple food, but also lead to a vicious cycle of worsening warming as the amount of carbon dioxide that can absorb greenhouse gases in the atmosphere decreases.
Air pollution is air containing high concentrations of pollutants that are likely to harm humans, animals, plants, or buildings. It is an important risk factor for the health of the world's population. Indeed, it is estimated that in 2012 alone, outdoor air pollution caused 3.7 premature deaths worldwide.
As the temperature of the Earth increases, icebergs in the polar regions melt and sea levels rise, flooding cities and islands in low places, reducing agricultural land, and changing coastline, so many problems are being budgeted in water resource management. In addition, experts are concerned that the increased activity of microorganisms could significantly increase the damage of pests and insects, which could lead to a significant decrease in crop yields. In addition, it is pointed out that abnormal weather causes changes in the ecosystem.
