Last season it was the hottest sixth since 1961, according to Inmet; The increase in greenhouse gas emissions and global warming are increasing temperatures
THE summer 2024 and 2025 entered history as the sixth warmer in Brazil since 1961, according to the National Institute of Meteorology (Inmet). The station that ended last Thursday, 6, was marked with high temperatures and rains above average.
On February 4th, The Municipality of Quaraí (RS), on the border with Uruguay, recorded 43.8 ° C. The station began on December 21, 2024 and ended on March 20 of this year.
High temperatures
According to the Institute, the temperature was 0.34 ° C. Above the average period between 1991 and 2020. “The thermometers recorded values higher than the average in most of the national territory, in particular Rio Grande do Sul, which had to face three intense heat waves: 17 and 23 January, February 2 and 12 and 8 March 2025?
Despite the effect of the La Niña phenomenon, which usually reduces the average global temperature, this summer was among the top ten never recorded. This season has become warmer since the 90s, according to Inmet data.
“The increased temperatures are aligned with a global trend. In the years 2023/2024, 2015/2016, 1997/1998 and 2009/2010, for example, the world was hit by El Niño, a phenomenon characterized by the Institute.
THE World Meteorological Organization (OMM) He warned that the last decade has been the hottest ever recorded. The increase in greenhouse gas emissions and global warming are increasing global temperatures.
Impacts of the climatic crisis
According to the weather society ClimatempoIn the global scenario, the average temperature between March 2024 and February 2025 was 1.59 ° C above the pre-industrial era, systematically exceeding the symbolic limit of Paris agreement.
“Even the typically milder months are becoming exceptional – February 2025, for example, was the third hottest ever recorded on the planet, according to Copernico”, strengthens the company.
“The temperature records we are experiencing are not simple natural oscillations, but part of a clear trend of global warming accelerated. The most worrying thing is that even the natural mechanisms that once contributed to balance time are losing strength. We must act now, combining science, technology and effective policies to mitigate these impacts “, warns the Meteorologist Pedro Regoto.

“The frequent rains in the country’s northern range were guided by the interstal convergence area (Zcit), a weather system formed by the interaction of the winds of the north -east wind, originally from the north hemisphere and also from the winds of the South -East, originating in the southern hemisphere”, adds the institute.
The rains exceeded 500 mm in the center of Brazil in Brazil, in the north-east center of the north-east, Mato Grosso of the central-southern do Sul, west of San Paolo, northern minas of Gerais, Espirito Santo, Rio de Janeiro and the central region and the western South, except Roraima, where smaller volumes were recorded.
