They're also the wild cards of climate science. - The science of glaciology and ice sheets is quite new, as methods to measure melting glaciers were only realized with the advent of aviation and lasers. - The world's sea levels are rising 3mm per year, and of that Greenland's ice sheet contributes 1mm – it is losing between 250 to 300 billion tons of ice per year. Three millimeters total is not much, but ice sheets don't always operate in a linear fashion. - No human has ever witnessed an ice sheet collapse. It is also such a rare event that models cannot accurately predict what the effect will be. Can we halt global warming before we reach that tipping point?
