Through a narrative review and theoretical reflection, it highlights how extreme events (such as floods, droughts, and wildfires) are intensifying, undermining ecosystems and disproportionately affecting vulnerable populations. The COVID-19 pandemic revealed structural weaknesses in health systems and the impact of denialism (information avoidance). Unlike ancient societies, today's humanity possesses scientific knowledge, technological resources, and strategies capable of mitigating these crises; yet political inertia and cultural resistance continue to hinder coordinated action. The historical experience of 536 serves as a warning: scientific knowledge alone is insufficient unless it is ethically, collectively, and responsibly mobilized. The article concludes that only through urgent, science-based collective action can humanity avoid repeating cycles of collapse.]]></p></abstract>
<abstract abstract-type="short" xml:lang="pt"><p><![CDATA[RESUMO Este artigo revisita o ano 536 d.C., frequentemente descrito como um dos períodos mais sombrios da história humana em razão de um colapso climático e da Peste Justiniana, traçando um paralelo com os desafios contemporâneos moldados pelas mudanças climáticas, pandemias e desinformação científica. Por meio de uma revisão narrativa e reflexão teórica, o estudo destaca como eventos extremos (como enchentes, secas e incêndios florestais) vêm se intensificando, comprometendo ecossistemas e afetando de forma desproporcional as populações vulneráveis. A pandemia de COVID-19 revelou fragilidades estruturais nos sistemas de saúde e o impacto do negacionismo (evitação da informação). Diferentemente das sociedades antigas, a humanidade atual dispõe de conhecimento científico, recursos tecnológicos e estratégias capazes de mitigar essas crises; contudo, a inércia política e a resistência cultural continuam a dificultar uma ação coordenada. A experiência histórica de 536 serve como alerta: o conhecimento científico, por si só, é insuficiente se não for mobilizado de forma ética, coletiva e responsável. O artigo conclui que apenas por meio de uma ação coletiva urgente e baseada na ciência a humanidade poderá evitar a repetição de ciclos de colapso.]]></p></abstract>
