A new study lead by Prof Julienne Stroeve says year-to-year forecasts of the Arctic’s summer ice extent are not yet reliable.

Triaxial rock deformation & physics cell capable of operating
at high temperature (1000ºC) and pressures (1400 MPa),
incorporating a 700 MPa pore fluid intensifier, utilizing
a 200 kN servo-controlled actuator, with AE monitoring, P
and S wave velocities and permeability measurement, using
15mm diameter by 45mm long specimens.
The high confining pressure of this apparatus can simulate the environment of rock at great depth in the earth (potentially over 50km deep in the crust).
The results of this type of experiment not only provides information about the mechanical properties of the rock, but when coupled with acoustic emission measurements can be used to identify patterns which can aid earthquake prediction.
