|a Cryo‐Hydrologic (CH) warming is proposed as a
potential mechanism for rapid thermal response of glaciers
and ice sheets to climate warming. We present a simple
parameterization to incorporate CH warming in thermal
models of ice sheets using a dual‐continuum concept, which
treats ice and the cryo‐hydrologic system (CHS) as overlapping
continua with heat exchange between them. The
presence of liquid water in the CHS due to surface melt leads
to warming of the ice. The magnitude and time‐scale of CH
warming is controlled by the average spacing between elements
of the CHS, which is often of the order of just 10’s of
meters. The corresponding time‐scale of thermal response is
of the order of years‐decades, in contrast to conventional
estimates of thermal response time‐scales based on vertical
conduction through ice (∼102–3 m thick), which are of the
order of centuries to millennia. We show that CH warming is
already occurring along the west coast of Greenland.
Increased temperatures resulting from CH warming will
reduce ice viscosity and thus contribute to faster ice flow. |
