There has been no rain or snow in many places in Brazil for decades. Why is the weather so abnormal?

due to the interaction of cold air and cold air flow in the polar regions (starting from 21st 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, and 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 the 22nd, the average precipitation in Rio exceeded 125mm in 24 hours, while the largest precipitation area was close to 15mm. On the south coast of Rio, a huge wave 3 meters long was washed up on the south bank, and the Brazilian navy began a comprehensive blockade from the southeast coast, prohibiting ships from entering the sea. There has been no rain or snow in many places in Brazil for decades. Why is the weather so abnormal?

The northward movement of Antarctic cold air and cold ocean current simultaneously caused a great deal of cooling and precipitation in central and southern Brazil. According to the forecast of the meteorological department, the temperature in Sã o Paulo State will remain at 8-13 degrees Celsius this weekend, and there was low temperature at the weekend.

In addition, from 21st, 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.

except Brazil, the temperature in parts of South America, Argentina, Chile, Uruguay, Paraguay, Bolivia and Peru has dropped significantly due to the influence of cold air and cold air. 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 children and grandchildren will face a situation that most of the drought and heat wave areas in the United States will become normal summer weather. If the carbon dioxide in the world increases and the atmosphere warms, these conditions will occur, such as the abnormal weather phenomenon in Brazil now.
