Changes in winds blowing in East Antarctica may be driving ice melt thousands of miles away.
With weeks left in the melt season, Arctic sea ice area is already below the annual low of the 1980s.
It's been less than a week, but the Larsen C ice shelf and the iceberg it calved are already changing.
Rising background temperatures are conspiring to make Arctic winter warm waves more common and persistent.
It's hard to imagine the Larsen C iceberg. These images help make it clear how massive it is.
Antarctica just calved one of the biggest icebergs ever recorded.
An iceberg the size of Delaware just broke away from Antarctica. Just how much ice that?
In addition to the main iceberg, a swarm of smaller icebergs is expected to break off Larsen C soon.
