Overview

• Hamburg is projected to have a climate similar to Milan or Madrid by the end of the century, with hotter, drier conditions becoming the norm.
• Sea-level rise could submerge key landmarks like the Hamburg Rathaus within 100 to 200 years, highlighting long-term risks to urban infrastructure.
• Springtime droughts in northern Germany have been increasing over the past 30 years, affecting agriculture, wildlife, and firefighting efforts.
• Extreme heat waves in Europe have doubled since pre-industrial times, with summers that are now decadal events potentially becoming annual by 2100.
• Urban greenery is under threat, as trees planted today may not survive in Hamburg's future climate conditions, challenging ecological stability.
