According to the 2020 Emissions Gap Report announced by United Nations Environment Program, the global temperature will rise 3.2 degrees in 2100. In North America and the middle east, forest fires and drought continued due to heatwaves, while Western Europe and central China are suffering from the highest level of rainfall since observations. In Brazil, the coldwave made its lowest temperature 17.96°F, which is -7.8°C.
Experts predict that the world temperature will rise two degrees Celcius in 2050. In that situation, about 420 million people will undergo extreme heat waves. Also, about 410 million people in the city will be running short of water. The melting of glaciers in Greenland and western Antarctica will raise sea levels by about 13 meters. The most worrying scenario is that the permafrost in Siberia melts and leaks billions of tons of methane, which speeds up temperature increases. Mark Linus predicted that six degrees Celcius rises would result in the release of methane hydrate. It is predicted to make all living things become a mass extinction.
The need to make efforts for the prevention of temperature rise is being underlined. Many countries including Korea are trying to reduce carbon dioxide to zero, however, a 4 to 5 degrees Celcius is already inevitable.
