The Arctic is a region in transformation. Warming in the region has been amplified, as
expected from ice‐albedo feedback effects, with the rate of warming observed to be∼ …

Understanding the role of atmospheric circulation anomalies on the surface mass balance of
the Greenland ice sheet (GrIS) is fundamental for improving estimates of its current and …

STATE OF THE CLIMATE IN 2015 Page 1 Special Supplement to the Bulletin of the American
Meteorological Society Vol. 97, No. 8, August 2016 STATE OF THE CLIMATE IN 2015 Brought …

The discovery of the 2012 extreme melt event across almost the entire surface of the
Greenland ice sheet is presented. Data from three different satellite sensors–including the …

Paleoclimate data show that climate sensitivity is~ 3 deg-C for doubled CO2, including only
fast feedback processes. Equilibrium sensitivity, including slower surface albedo feedbacks …

Greenland ice sheet mass loss has accelerated in the past decade responding to combined
glacier discharge and surface melt water runoff increases. During summer, absorbed solar …

A combined analysis of remote sensing observations, regional climate model (RCM) outputs
and reanalysis data over the Greenland ice sheet provides evidence that multiple records …

I suggest that a'scientific reticence'is inhibiting the communication of a threat of a potentially
large sea level rise. Delay is dangerous because of system inertias that could create a …

The following graphics are supplemental to Chapter 2 (Global Climate). In most cases, a
particular graphic is analagous to one provided in the chapter, but employs an alternate …

Analyses of remote sensing data, surface observations and output from a regional
atmosphere model point to new records in 2010 for surface melt and albedo, runoff, the …
