Climate risk country profile: Brazil (2025)

This climate risk profile on Brazil provides a high-level assessment of the country’s exposure to climate risks and changing weather patterns. It synthesizes historical data, future projections, and policy responses to support decision-makers in integrating climate considerations into development planning. Drawing on the Climate Change Knowledge Portal and the latest IPCC findings, the profile highlights both rapid-onset hazards such as floods, storms, and heatwaves, and slower-onset changes including temperature rise, rainfall decline, and sea level rise. Its purpose is to guide adaptation and resilience efforts by making climate data accessible and actionable.

Brazil’s size and ecological diversity make it particularly vulnerable to these shifts. Average temperatures have risen more sharply in recent decades, dry seasons are lengthening, and rainfall is projected to decline in key regions, heightening drought risk. Extreme heat and heavy rainfall events are expected to become much more frequent, with major implications for health, infrastructure, and food security. Rising seas and warmer oceans threaten coastal zones, fisheries, and biodiversity. As a leading agricultural producer and home to globally significant ecosystems, Brazil faces the challenge of safeguarding livelihoods while achieving ambitious climate commitments, including up to 67% emissions reductions by 2035 and stronger adaptation strategies across critical sectors.
