Resumo(s)
As alterações climáticas (AC) constituem um dos maiores desafios globais do século XXI, com impactos que ultrapassam largamente a esfera ambiental, afetando a saúde
pública, a economia e a segurança das sociedades. O presente trabalho analisa as múltiplas consequências deste fenómeno, sob uma perspetiva securitária, distinguindo entre as
vertentes “safety”, como riscos diretos para a vida humana e infraestruturas, e “security”, como riscos para a ordem pública, estabilidade social e geopolítica.
A investigação parte de um enquadramento teórico, que explora a evolução do estudo das AC, desde as suas origens científicas até ao estado atual do conhecimento, confrontando as visões que atribuem responsabilidade à ação humana, com as correntes mais céticas, que defendem a variabilidade natural do clima. Complementarmente, procede-se à análise dos impactos económicos, sociais e sanitários já registados a nível global, evidenciados em relatórios internacionais e em literatura especializada. No plano empírico, recorre-se a questionários e entrevistas realizadas a entidades nacionais relevantes, no domínio da segurança, de modo a captar perceções institucionais
sobre a preparação, vulnerabilidades e estratégias de resposta face às AC. Conclui-se que os efeitos deste fenómeno configuram uma ameaça multidimensional, exigindo não apenas políticas de mitigação ambiental, mas igualmente medidas de reforço da segurança interna, proteção civil (PROCIV) e cooperação internacional. A abordagem integrada entre ciência, política e segurança revela-se, assim, indispensável para enfrentar os desafios presentes e futuros.
Climate change constitutes one of the greatest global challenges of the 21st century, with impacts that extend far beyond the environmental sphere, affecting public health, economy, and security of societies. This dissertation examines the multiple consequences of this phenomenon, from a security perspective, distinguishing between the safety dimension, as the direct risks to human life and infrastructures, and the security dimension, as indirect risks to public order, social stability, and geopolitics. The research begins with a theoretical framework that explores the evolution of climate change studies, from their scientific origins to the current state of knowledge, contrasting perspectives that attribute responsibility to human action, with more sceptical views that emphasise the natural variability of climate. In addition, the analysis considers the economic, social, and health impacts already observed worldwide, as evidenced in international reports and specialised literature. At the empirical level, the study employs questionnaires and interviews conducted with key Portuguese security institutions in order to capture institutional perceptions regarding preparedness, vulnerabilities, and strategies to address the challenges of climate change. The findings indicate that the effects of this phenomenon represent a multidimensional threat, requiring not only environmental mitigation policies, but also enhanced internal security measures, civil protection strategies and international cooperation. An integrated approach between science, policy, and security thus emerges as indispensable to facing present and future challenges.
