Rio de Janeiro
Brazil
Rio de Janeiro is projected to face significant climate challenges that will exacerbate public health risks and environmental stability. The city is expected to experience more frequent and intense heatwaves, which pose serious threats to residents, especially vulnerable populations. These elevated temperatures are likely to increase the arbovirus transmission risk, leading to rising incidences of diseases like dengue and Zika, which can overwhelm local healthcare systems. Additionally, rising temperatures and changing precipitation patterns create conditions conducive to the spread of malaria, further straining public health resources. As these climate hazards intensify, they may also impact local ecosystems and biodiversity, altering natural habitats and potentially leading to greater urban heat island effects. This combination of climate risks highlights the urgent need for better understanding and data collection, as technology-enabled climate resilience solutions have not yet been documented for the city. The future demands strategic planning to mitigate these vulnerabilities.
Hazard Outlook
How will Rio de Janeiro's projected climate hazards compare to other cities under a 3.0°C future warming scenario?
Elevation
At 27 m elevation, Rio de Janeiro faces elevated risk from coastal flooding and sea level rise.
Maximum Temperature
Rio de Janeiro's projected maximum temperature of 9.4°C is near the median of cities globally under a 3.0°C warming scenario.
Maximum Rainfall
Rio de Janeiro's projected maximum rainfall of 9 mm is near the median of cities globally.
Longest Heatwave
Rio de Janeiro may experience heatwaves lasting up to 3 days, lower than most other cities.
Heavy Rainfall Days
With 9 days of heavy rainfall expected, Rio de Janeiro ranks lower than most cities for extreme precipitation events.
