The climate sensitivity classically defined is the response of global mean temperature to a forcing once all the «fast feedbacks» have occurred (atmospheric temperatures, clouds, water vapour, winds, snow, sea ice etc.), but before any of the «slow» feedbacks have kicked in (ice sheets, vegetation, carbon cycle etc.).

Bromwich said the disagreement between climate model predictions and the snowfall and temperature records doesn't necessarily mean that the models are wrong.

The displacement of the platform is analogous to global mean temperature, and the stiffness of the spring is analogous to climate sensitivity.

One common measure of climate sensitivity is the amount by which global mean surface temperature would change once the system has settled into a new equilibrium following a doubling of the pre-industrial CO2 concentration.

The team increased one forcing agent (see sidebar) in a climate model, for example carbon dioxide, and decreased another, say methane, so that global mean temperature didn't change.

The global mean temperature rise of less than 1 degree C in the past century does not seem like much, but it is associated with a winter temperature rise of 3 to 4 degrees C over most of the Arctic in the past 20 years, unprecedented loss of ice from all the tropical glaciers, a decrease of 15 to 20 % in late summer sea ice extent, rising sealevel, and a host of other measured signs of anomalous and rapid climate change.
