🗞️ Driving the news: A new report from Central London Forward warns that climate change impacts could cost London up to £15 billion per year by 2050 if authorities fail to implement robust adaptation measures
• Rising heatwaves, floods, and droughts threaten health, infrastructure, and the economy

🔭 The context: London faces intensified risks due to the Urban Heat Island effect, which can raise local temperatures by up to 10°C compared with surrounding areas
• The report highlights the need for green infrastructure, retrofitting social housing, and improved drainage to prevent flooding
• Currently, responsibility falls largely on local authorities without a unified funding framework

🌍 Why it matters for the planet: The situation illustrates how urban centers are both vulnerable to and drivers of climate impacts
• Heat islands, impermeable surfaces, and dense development exacerbate extreme weather effects, demonstrating the environmental consequences of urbanization and the urgency for climate-resilient planning

⏭️ What’s next: City Hall has launched the Heat Ready London initiative, coordinating local authorities, health services, transport, and emergency agencies to enhance resilience
• Long-term investments in green spaces, permeable paving, and climate-adapted housing will be critical to mitigate future costs and protect vulnerable populations

💬 One quote: “It is vital that we make central London more climate resilient. However, the responsibility for action currently falls on local authorities, without any sustainable funding or a common framework.” – Charlie Rainsford, Central London Forward
