Meteorologist Sven Sundgaard explains how Arctic sea ice has a direct impact on Minnesota's climate.

The amount of springtime sea ice in the Arctic set a record low this month, continuing a trend of shrinking ice at the top of the world.

The Arctic was once ice-free, and it could happen again -- which would exponentially increase the severity of catastrophic sea level rise, according to new research.

Arctic temperatures spiked 36 degrees Fahrenheit, or 20 Celsius, above normal. By the end of the month, sea ice was at its lowest level ever recorded for February.
