The world record for longest distance run continuously is held by Dean Karnazes, who ran 563 km (350 miles) in 80 hours 44 minutes without stopping.

A 2020 study reports that by 2050 global warming could be spreading in the deep ocean seven times faster than it is now, even if emissions of greenhouse gases are cut.
