It is not that the polar regions are amplifying the warming «going on» at lower latitudes, it is that any warming going on AT THE POLES is amplified through inherent

To give
feedback that strengthens learners» motivation and persistence, teachers should keep five principles in mind: A learning context in which students are truly engaged makes

feedback focuses on the
processes a learner used; praise isn't the best way to give a
positive message; and
feedback focused on judging the learner (even positively) can backfire.

Granted, it is «slow» right now, but the melting has been increasing quite substantially, and whereas the IPCC had been speaking in the neighborhood of a sea level increase of 50 cm, figures between one to two meters are becoming common as the result of observed changes, and with the nonlinear
processes and resulting
positive feedback, Jim Hansen has suggested that a sea level doubling per decade and increase of several meters (up to 5 m) by the end of the century is more realistic.
