Shipping routes across the Arctic are going to open up significantly this century even with a best-case reduction in CO2 emissions, a new study suggests. Researchers have investigated how the decline in sea-ice, driven by warmer temperatures, will make the region more accessible. They find that by 2050, opportunities to transit the Arctic will double for non ice-strengthened vessels. These open-water ships will even be going right over the top at times. [Source: BBC News]
