The source of the River Thames has moved five miles downstream for the first time in its history. While parts of the riverbed in Gloucestershire regularly dry out during the summer, experts said it was a worrying sign of the impact of the climate crisis to see the Thames begin flowing so far downstream.
It comes after weeks of dry spells, and temperatures reaching in excess of 40C in parts of the UK last month.
Christine Colvin, advocacy and engagement director of the Rivers Trust, said: "What we're seeing at the source of the iconic River Thames is sadly emblematic of the situation we're facing across the country, now and in future. Whilst it's not uncommon for the source to be dry in the summer, to only be seeing the river flowing five miles downstream is unprecedented.
