Year of 2023 Brazil’s hottest on record

The year 2023 was the hottest in the planet’s history and also the hottest on record for Brazil. The average temperature in the country was 24.92 degrees Celsius (°C), 0.69°C above the historical average for 1991–2020, 24.23°C.

According to a survey by the National Institute of Meteorology (Inmet) nine of the 12 months of 2023 had monthly temperature averages above the historical average for 1991–2020, with September standing out as showing the greatest difference between the recorded value and the historical average.

Throughout the year, Brazil faced nine heatwave episodes, reflecting the impacts of the El Niño phenomenon, which tends to favor rising temperatures across the planet.

In addition, the institute reported, other factors have contributed to the occurrence of increasingly extreme events, like the increase in the global temperature of the Earth’s surface and the oceans.

After analyzing the deviations in average annual temperatures in Brazil from 1961 to 2023, the authority found a statistically significant upward trend in temperatures over the years, which may be linked to climate change as a result of rising global temperatures and local environmental changes.

According to the Provisional State of the Global Climate in 2023, published by the World Meteorological Organization on November 30, 2023, the average global surface temperature was 1.4°C above the historical average for 1850–1900 by October of last year.

The figure makes 2023 the hottest year in 174 years of meteorological measurements. Yesterday (Jan. 9), the European Union’s Copernicus Climate Change Service confirmed that last year was the hottest on record for the planet and probably the hottest in the world in the last 100 thousand years.
