It hasn't rained or snowed in many parts of Brazil for decades. Why is the weather so abnormal?

Due to the interaction between polar cold air and cold air (starting from 2 1 local time), the temperature in central and southern Brazil has dropped to the lowest level in August, which is the lowest level for many years. Weather phenomena also include a lot of rainfall and frost. There have been several storms in the coastal areas of southeastern Brazil. On the morning of 22nd, the 24-hour average precipitation in Rio exceeded 1.25mm, and the maximum precipitation area was close to 1.50mm ... On the south bank of Rio, a 3-meter-long wave washed up on the south bank, and the Brazilian navy began to completely block it from the southeast coast, prohibiting ships from entering the sea. It hasn't rained or snowed in many parts of Brazil for decades. Why is the weather so abnormal? The Antarctic cold air and cold ocean current move northward at the same time, resulting in a large amount of cooling and precipitation in central and southern Brazil. According to the forecast of the meteorological department, the temperature in S? o Paulo will remain at 8- 13 degrees Celsius this weekend, and there will be low temperature this weekend.

In addition, from 2 1, dozens of cities in rio grande do sul and Santa Catarina in southern Brazil experienced a rare low temperature below zero degrees Celsius in August, accompanied by all kinds of snow and frost.

In addition to Brazil, due to the influence of cold air and cold air, the temperature in parts of South America, Argentina, Chile, Uruguay, Paraguay, Bolivia and Peru dropped significantly. All the carbon dioxide and other greenhouse gases in the atmosphere disappear, and the earth will become a cold and lifeless world like Mars overnight. In fact, these gases have been increasing since the beginning of the industrial revolution.

If we don't slow down the temperature rise, then our descendants will face a situation, and most drought and heat wave areas in the United States will become normal summer weather. If the global carbon dioxide increases and the atmosphere warms, these situations will occur, such as the abnormal weather phenomenon in Brazil now.
