London and climate change

London is built astride the River Thames. Whilst not a traditional delta, the capital is further bisected by 12 tributaries and the tidal influence of the North Sea extends almost entirely through the city. The city had 8.8 million inhabitants at its high point in 1939. The population steadily declined to 6.7 million in 1988 and then increased again to the present-day 7.6 million. It is expected to keep growing to 8.9 million by 2031.

London has a temperate marine climate. Because the Gulf Stream reduces seasonal variation, much of the UK is poorly adapted to extreme weather. Surface water floods are however a significant short-term climate risk to London. A 1 in 200 year rainstorm event today would flood up to 680,000 properties in London.
