Um recente estudo aponta que o Rio de Janeiro está entre as cidades que podem sofrer os impactos mais severos das mudanças climáticas. Segundo informações divulgadas pelo jornal britânico ‘The Guardian’, a capital fluminense está na lista de áreas que podem enfrentar um aumento de temperatura acima de três graus Celsius nos próximos anos, juntamente com Miami (EUA), Xangai (China) e Haia (Holanda).

O relatório destaca que essas cidades também correm o risco de ficar abaixo do nível do mar, o que representa uma ameaça iminente para milhões de habitantes. O aumento das temperaturas e a elevação do nível do mar são consequências diretas das emissões de gases de efeito estufa, principalmente o dióxido de carbono, na atmosfera.

Especialistas alertam que, além das emissões de gases poluentes, fenômenos naturais, como a descontinuidade do campo magnético do planeta na região do Atlântico Sul, podem estar contribuindo para o aquecimento global. O engenheiro Gerardo Portela, especializado em Gerenciamento de Crise, ressalta a necessidade urgente de reduzir as emissões de gases de efeito estufa para mitigar os impactos das mudanças climáticas.

A descontinuidade no campo magnético da Terra, que atua como um escudo protetor contra partículas solares e influencia a comunicação e navegação por satélite, representa um desafio adicional para os cientistas, que buscam entender seu papel no aquecimento global e nos padrões climáticos.

A fragilização do campo magnético terrestre, que está atualmente em sua fase mais fraca dos últimos cinco séculos, coloca em risco não apenas as condições climáticas, mas também a biodiversidade e os ecossistemas globais. A compreensão e o enfrentamento desses desafios exigem uma abordagem coordenada e urgente por parte da comunidade internacional.
