Video: How can sea ice be melting at one pole and increasing at the other?

Sea ice surrounding Antarctica reached a new record high extent this year, covering more of the southern oceans than it has since scientists began a long-term satellite record to map sea ice extent in the late 1970s. Meanwhile, the upward trend in the Antarctic is only about a third of the magnitude of the rapid loss of sea ice in the Arctic Ocean.

What’s going on here? If global warming is real, shouldn’t sea ice be declining at both of Earth’s two poles?

NASA’s Swift satellite has detected flares from a nearby red dwarf star that are the strongest, hottest, and longest-lasting sequence of stellar flares ever seen. The initial blast from this record-setting series of explosions – detected by Swift in April, 2014 – was as much as 10,000 times more powerful than the largest solar flare ever recorded.
