Natural Environmental Swings Cause Up To Half Of Arctic Sea Ice Loss
Natural Environmental Swings Cause Up To Half Of Arctic Sea Ice Loss
Sea ice in the Arctic has been melting at a record-breaking pace. Scientists blame a warming climate for most of that, but researchers have now teased out a natural cycle for how Arctic sea ice melts year-to-year.
Based on that cycle, they conclude that 30 percent to 50 percent of the melting is due to natural causes, while human-caused warming is responsible for the rest.
