Canals cool down cities during heatwaves – new research
A canal boat moored on the Regent's Canal in London. BBA Photography/Shutterstock Canals in Great Britain and Ireland cool city neighbourhoods up to 50 metres from their banks, particularly during heatwaves. That’s the key finding of our new research which modelled the impact of canals on urban temperatures – quantifying their importance for the millions of people who live and work nearby. While canals are found widely throughout UK and Irish cities, reflecting the legacy of the Industrial…

Unresolved 15% Skepticism and Scoping Dispute (Counter-intuitive)
Despite the strong findings, major infrastructure bodies challenge the study's scope, arguing that the 50-meter cooling radius is too narrow to justify large-scale public spending, leading to a temporary policy freeze.
Watch for: The Ministry of Transport publishes a technical paper citing 'insufficient longitudinal data' on canal effectiveness. · A prominent engineering lobby issues a public statement questioning the predictive validity of thermal modeling.
-
Unresolved 15% Public Health Campaign Uptake
