Current Climate Challenges in Belém
Belém, Brazil, is currently hosting the COP30 climate negotiations, a pivotal event that could shape the future of global climate policy. However, the city itself faces significant climate threats, particularly from rising temperatures and sea levels. Since 1991, Belém has experienced an average temperature increase of 0.23°C per decade, a rate that surpasses natural climate variations. Projections indicate that this trend will continue, with potential temperature increases of 1.2°C in an optimistic scenario aligned with the 2015 Paris Agreement, and up to 3.6°C in a pessimistic scenario where greenhouse gas emissions continue to rise.
Impacts of Rising Temperatures
The implications of these temperature increases are severe. Belém could face extreme heatwaves, with temperatures potentially exceeding 39°C, which approaches human physiological limits. The combination of high humidity and elevated temperatures may lead to dangerously high wet-bulb temperatures, increasing the risk of heat-related health issues, including heat stroke. As climatologist Samy Kraiem notes, these projections underscore the urgent need for immediate action to reduce emissions.
Sea Level Rise Threats
In addition to rising temperatures, Belém is vulnerable to sea level rise. Projections suggest that, under optimistic conditions, mean sea levels could rise by approximately 35 cm by 2080. In a more pessimistic scenario, the increase could range from 50 to 56 cm, with the possibility of reaching up to 1.45 meters. This rise poses a significant threat to Belém's coastal infrastructure and surrounding areas.
Health Implications and the Belém Health Action Plan
The health impacts of climate change are also a focal point of the discussions at COP30. A special report by the World Health Organization (WHO) highlights that one in 12 hospitals could face climate-related shutdowns. The Belém Health Action Plan, launched during COP30, aims to integrate health considerations into climate policy. WHO Director-General Dr. Tedros Adhanom Ghebreyesus emphasized that "the climate crisis is a health crisis - not in the distant future, but here and now."
Ethel Maciel, COP30's special envoy for health, outlined the plan's three pillars: integrating climate and health data, building resilient health systems, and fostering research and innovation for climate-related health challenges. She stressed the urgency of preparing health facilities for extreme weather events, citing recent flooding in Brazil that exacerbated health crises.
Conclusion: The Importance of COP30 Decisions
The outcomes of the COP30 negotiations are crucial for Belém and the broader global community. As Thibault Laconde, founder of Callendar, stated, "These projections show that adaptation alone will not be enough." The decisions made in Belém could determine whether the city can avoid crossing critical climatic tipping points, emphasizing the need for immediate and effective action to mitigate climate change impacts.
