“What should I tell her?
She’s going to ask.
If I ignore it, it gets uncomfortable
She’ll want to argue about the past.”

Well this is a fine how-do-you-do:
Two scientific papers released on Monday by the journals Science and Geophysical Research Letters came to similar conclusions by different means. Both groups of scientists found that West Antarctic glaciers had retreated far enough to set off an inherent instability in the ice sheet, one that experts have feared for decades. NASA called a telephone news conference Monday to highlight the urgency of the findings.
Those six glaciers alone could cause the ocean to rise four feet as they disappear, Dr. Rignot said, possibly within a couple of centuries. He added that their disappearance will most likely destabilize other sectors of the ice sheet, so the ultimate rise could be triple that.
As usual, the believed causes are complex and multi-layered. Bu that doesn’t make for good sound bites.
And while the cause of the stronger winds is somewhat unclear, many researchers consider human-induced global warming to be a significant factor. The winds help to isolate Antarctica and keep it cold at the surface, but as global warming proceeds, that means a sharper temperature difference between the Antarctic and the rest of the globe. That temperature difference provides further energy for the winds, which in turn stir up the ocean waters.
Sorry, Mother. Sorry, daughter.
