00:00:00 - 00:05:00

In the YouTube video "Inundações no Rio Grande do Sul: o antes e depois da destruição pelas chuvas" (Floods in Rio Grande do Sul: Before and After the Destruction by the Rains), André Biernath of BBC News Brasil discusses the historic floods in Rio Grande do Sul, Brazil, which are the biggest climatic disaster in the state's history. The excessive rainfall led to record-breaking flooding in several cities, causing widespread damage and fatalities. The Guaíba lake reached a historic high of 4.77 meters, and the situation led to a state of emergency in over 330 cities. The flooding was caused by a combination of a low-pressure system, a moisture corridor from the Amazon, and a heat wave in the central part of the country. Experts consider this unusual combination rare but identify a relationship between the heavy precipitation observed in the region since the 1950s and human-induced climate change, increasing the likelihood of more frequent and intense floods in the future.

The floods are considered the biggest climatic disaster in the state's history, with devastating consequences and fatalities. The video provides a comparison of the rainfall volumes and the extent of the flooding to historical averages. The excessive rainfall led to record-breaking flooding in several cities, including Soledade, Caxias do Sul, Santa Rosa, Ibirubá, Cruz Alta, Bom Jesus, and Santo Augusto. The Guaíba lake, which surrounds Porto Alegre and its metropolitan area, reached a historic high of 4.77 meters, surpassing the previous record of 4.76 meters set in 1941. The flooding caused widespread damage in the capital city, including the historic center. The situation repeated itself throughout the state, leading to a state of emergency in over 330 cities, representing two-thirds of the nearly 500 municipalities in the state. The governor of the state, Eduardo Leite, acknowledged that the recovery effort would require an extraordinary effort, similar to the post-World War II European reconstruction plan. The meteorologists interviewed by BBC News Brasil explained that the heavy rains were caused by a combination of three main factors: a low-pressure system, a moisture corridor from the Amazon, and a heat wave in the central part of the country. The unusual combination of these factors is considered rare by experts. However, a UN climate panel report published in 2023 identified a relationship between the heavy precipitation observed in the region since the 1950s and human-induced climate change. Unfortunately, there is a high probability that these events will occur more frequently and intensely in the future.
• 00:05:00 In this section of the YouTube video titled "Inundações no Rio Grande do Sul: o antes e depois da destruição pelas chuvas" (Floods in Rio Grande do Sul: Before and After the Destruction by the Rains), the speaker discusses the worsening effects of floods in Rio Grande do Sul due to climate change. He mentions that while the floods have always caused damage, their impact is becoming increasingly severe as temperatures rise. The speaker then signs off, encouraging viewers to stay informed about the extreme weather event through BBC News Brasil's website, social media, and YouTube channel.
