Historical Imagery of Greenland Glaciers Lessens Sea Level Rise Alarm
Source: World Climate Report
A new study using historical images of glaciers in southeast Greenland to investigate glacier response to climate changes suggests that the recently observed acceleration of ice loss from Greenland may not be a long-term phenomenon. Instead, as marine terminating glaciers reach their grounding line and as the termini of land-terminating glaciers migrate upwards in elevation, ice loss rates from glacial discharge may slacken. According to Anders Bjørk and co-researchers:
Such results throw a bit of cold water on alarmist ideas that rising temperatures will lead to ever-accelerating ice loss from Greenland and accelerating sea level rise.
For example, Eric Rignot and colleagues (2011) last year documented an acceleration in the rate of ice loss from Greenland (and Antarctica) over the past two decades. They extrapolated this acceleration into the future, to arrive at potential future sea level contributions from the loss of ice sheets:
