In this regard, I would observe that at least one important AGW effect, rising sea level, does not depend on a specific regional outcome so much as on global mean T.

Global average temperature is lower during glacial periods for two primary reasons: 1) there was only about 190 ppm CO2 in the atmosphere, and other major greenhouse gases (CH4 and N2O) were also lower 2) the earth surface was more reflective, due to the presence of lots of ice and snow on land, and lots more sea ice than today (that is, the albedo was higher).

Arctic sea ice has reached record lows this winter around Greenland and elsewhere, following the predictions of remarkably accurate models based on global warming.

With global GHG emissions and concentrations continuing to increase; with climate change intensifying changes in ecosystems, ice sheet deterioration, and sea level rise; and with fossil fuels providing more than 80 % of the world's energy, the likelihood seems low that cooperative actions will prevent increasingly disruptive climate change over the next several decades.
