What happened

How Britain's mapmakers track climate change Alexander Pol Deputy Editor Once used to defend Britain's shores against Napoleonic France, the Ordnance Survey's detailed maps are now essential for tracking and adapting to climate change.

Why it matters

"I would argue there is no clearer way to see the impact of climate change than looking at a traditional map," Tom Gray, a utilities and transport expert for Britain's national mapping agency, told AFP.

Common ground

He was sitting in front of an aerial photograph of dry land projected onto a large screen at the OS headquarters in the port city of Southampton, southern England.
