Hà Noi
Vietnam
Hà Nội is projected to face several climate hazards that pose serious risks to its inhabitants and ecosystems. It will experience extreme heat and dangerous heat extremes, leading to more frequent heatwaves that amplify health issues. Heavy rainfall events are expected to become more common, which may result in flooding and infrastructure stress. Additionally, the city faces prolonged drought conditions that can undermine water security and agricultural productivity. Health risks are elevated as rising temperatures contribute to a high arbovirus transmission risk, including diseases such as dengue fever. Furthermore, the potential for increased malaria transmission due to changing climate conditions adds to the public health concerns. These intertwining climate hazards underline the vulnerabilities that Hà Nội is likely to confront in the foreseeable future, necessitating attention for effective mitigation and adaptation strategies in the face of these challenges.
Hazard Outlook
How will Hà Noi's projected climate hazards compare to other cities under a 3.0°C future warming scenario?
Elevation
