Professor Richard Pancost from the University of Bristol Cabot Institute, added: «When we account for the
influence of the ice

The latter is almost linearly related to
changes in ice
sheet volume; the former, however, is
influenced by a range of factors, including atmosphere / ocean dynamics and
changes in Earth's gravitational field, rotation, and crustal and the mantle deformation associated with the redistribution of mass between land ice and the ocean.
«These are two of the largest and most rapidly
changing glaciers in Antarctica, so the potential for their evolution to
influence each other is important to consider in modeling ice
sheet behavior and projecting future sea level rise,» Dustin Schroeder, a Stanford geophysicist who led the study, told Earther.
This result would be strongly dependent on the exact dynamic response of the Greenland ice
sheet to surface meltwater, which is modeled poorly in todays global models.Yes human
influence on the climate is real and we might even now be able to document
changes in the behavior of weather phenomena related to disasters (e.g., Emanuel 2005), but we certainly haven't yet seen it in the impact record (i.e., economic losses) of extreme events.
But who's to say that if we had enough data and understanding, these spikes and dips could not be thoroughly explained by solar
influences, volcanic eruptions, greenhouse gas
changes, ice
sheet dynamics, etc..?
