Dry weather and a layer of pollution cover the sky in Sao Paulo, Brazil, on September 10, 2024. The atmospheric blockage, a dry air mass, persists at least until Saturday, September 14. Until then, the forecast points to days with above-average temperatures and low air humidity for much of the day, which increases the risk of fires and wildfires in vegetated areas of Brazil. In addition, atmospheric conditions do not favor the dispersion of pollutants, which contributes to poor air quality. (Photo by Fabio Vieira/FotoRua/NurPhoto via Getty Images)
