In the last five years, more than half of COMET metros have been impacted by flooding (74%), high winds/storms (62%) and extreme heat (50%), and many have also been impacted by cold weather and snow (45%), drought (22%) and wildfire (16%). Concerningly, three quarters of metros have noticed an increase in weather events impacting metro operations in recent years. These events pose significant risks to metro infrastructure, operations and the safety of passengers and staff.
The latest COMET study on Preparing for Extreme Weather and Climate Change reviews how member metros prepare for and manage upcoming periods of extreme weather and their plans to adapt infrastructure and operations in the longer term to deal with the impacts of climate change.
