Juneau, Alaska, is partially evacuated due to the risk of flooding caused by runoff from a glacial lake amid global warming.

As Donald Trump and Vladimir Putin meet, Alaska's capital Juneau is facing a flood alert. More than 30,000 residents are affected by the risk of a flood that could exceed three meters, generated by rapidly melting ice. Timelapse footage illustrates the process, and experts stress the link to climate change. A glacier 20 kilometers (12 miles) away could break off, amplifying the effects.
