Lisbon is facing the repercussions of climate change as it grapples with the aftermath of recent storms that caused significant flooding and damage in various parts of Portugal. In Coimbra, the Mondego River overflowed, leading to the evacuation of around 3,000 residents, while Lisbon experienced localized flooding with damages mainly attributed to fallen trees and roof destruction. This disparity in impact highlights the varying vulnerabilities of different cities in Portugal to extreme weather events.

In response to these challenges, Lisbon is implementing the PDGL (Plano Geral de Drenagem de Lisboa), a comprehensive €250 million plan designed to enhance the city's drainage systems and reduce the risk of flooding from torrential rains. This plan, which includes the construction of underground tunnels, aims to ensure that the city is better prepared for future climate-related challenges, reflecting a proactive approach to urban planning in the face of increasing climate risks.

The investment in green areas as a part of this strategy not only aims to provide immediate relief from extreme heat but also contributes to the long-term sustainability of the urban environment. By prioritizing green spaces, Lisbon is striving to create climatic refuges that can absorb excess rainwater and provide shade, thereby improving the overall quality of life for its residents while simultaneously addressing the pressing issue of climate change.
