The Atlantic Meridional Overturning Circulation (AMOC), a critical ocean current system, is slowing down due to climate change. This slowdown has significant implications for global climate patterns, including cooler temperatures in the North Atlantic region, altered atmospheric circulation, and changes to precipitation patterns.
If the AMOC declines significantly, it could lead to a 5°C reduction in UK average temperature compared to expected levels. Changes in atmospheric circulation may displace the mid-latitude jet stream poleward, increasing winter storms over northern Europe and leading to higher seasonal precipitation and wind speeds. Summer precipitation in northern Europe would decrease due to reduced evaporation, while parts of southern Europe might experience increased summer rainfall.
The slowdown will have far-reaching impacts on engineered systems, including buildings, infrastructure, and physical structures. This could lead to environmental conditions that these systems are not designed for, posing significant challenges for adaptation and resilience-building activities. The engineering profession must take action to address these challenges and develop new technologies and approaches.
To spark a discussion on this topic, the Institution is hosting two events. A free webinar will be held on May 20th, and an interactive in-person workshop session will take place on July 3rd at Exeter University. Both events are free to attend, and interested individuals should express their interest through private messaging.
Note: The impacts of AMOC slowdown vary depending on climate models and emission scenarios.
