After a two-year around-the-world ocean voyage inspired by Charles Darwin, scientists and crew sailed home on a historic vessel into Rotterdam Thursday bearing a warning about climate change -- but also a message of hope.
The majestic three-masted Oosterschelde, the last remaining vessel from a fleet of Dutch schooners that criss-crossed the globe in the early 20th century, arrived to a welcome befitting a voyage of more than 40,000 nautical miles (74,000 kilometres, 46,000 miles).
