An Antarctic ice melt leading to a 5m global sea-level rise would render London's Thames Barrier obsolete. We're talking about a threat that could manifest by 2050 if climate targets aren't met. The engineering challenge to upgrade or replace the barrier is colossal, think at least £10 billion just for the engineering, not factoring in the social costs. Add land acquisition in London's expensive real estate market, and the relocation of communities, you could easily double or triple that cost. To put it in perspective, this could rival or surpass projects like the Channel Tunnel in terms of financial and logistical complexity. And yet, there's a startling lack of political and public dialogue on this urgent issue. This isn't just about engineering; it's about national security and public safety. The disconnect is alarming.
