Record High Temperatures Haunt South America Amidst Global Climate Contrasts

Last week, South America faced record high temperatures as Rio de Janeiro recorded 44C, while Brazil activated a heat protocol amid dry conditions. In Argentina, temperatures are also set to rise significantly, in contrast to freezing conditions in North America. Central Africa is also facing extreme heat, indicating a broader climate crisis.

In contrast to the cold conditions experienced in North America, South America is currently facing extreme heat as the continent approaches the end of summer. Recently, Rio de Janeiro recorded its highest temperature in over a decade, hitting 44C at the Guaratiba weather station—14C above the usual February average. Furthermore, Rio is on track for one of its driest Februarys, prompting authorities to activate a level 4 heat protocol to address public health concerns.

While temperatures in Brazil are now stabilizing, high temperatures have begun impacting north-western Argentina, where forecasts predict highs between the upper 30s to low 40s Celsius, exceeding seasonal averages by 10 to 15C. Unlike the conditions in Brazil, these temperatures may trigger thunderstorms, potentially leading to significant rainfall in certain areas. The extreme heat is largely due to a high-pressure system over the southern Atlantic, facilitating warming air movement towards the continent’s southern regions.

Meanwhile, contrasting weather patterns are evident in North America, particularly in Canada and the U.S., where Saskatchewan experienced temperatures plunging into the negative 40s Celsius, and North Dakota recorded a low of -37.8C. This resulted in a stark temperature differential, exceeding 80C between the two continents on the same day. Central and eastern Africa are also experiencing severe heat, particularly in South Sudan, where educational institutions have been forced to close in response to extreme temperatures, highlighting the global ramifications of rising heat levels.

In summary, South America is currently grappling with intense heat, particularly in Brazil and Argentina, resulting in record-high temperatures and significant public health measures. Conversely, North America faces severe cold, demonstrating a dramatic temperature disparity. Furthermore, regions in Africa are similarly afflicted by extreme heat, emphasizing a widespread climatic concern affecting multiple continents.
