Melting Arctic ice spells trouble for Hokkaido tourism

National Geographic warns of a threat to Hokkaido’s natural beauty:
Free-floating pieces of ice that form each winter in the Sea of Okhotsk travel about 620 miles (1,000 kilometers) to Hokkaido’s Shiretoko Peninsula. The ice, which normally lingers near the coast for up to four months, is key to the region’s rich biodiversity, including many rare seabirds and marine mammals.
In recent years, however, the peninsula has seen noticeably less drift ice, raising fears that global warming is to blame.
Arctic sea ice overall has been disappearing much faster than initially predicted, with some experts saying that the region’s summer ice could be gone within five years.
According to the article, the ice carries nutrients that are vital to the survival of plankton, which form the base of the food chain around Hokkaido. Reduced ice drift could seriously damage the ecosystem of Shiretoko National Park.
