(This makes it clear why glaciers in coastal Norway are not as strongly influenced by temperature — at these locations, winter precipitation typically exceeds several ice - equivalent meters per year).

Scientists previously believed that temperature and sunlight drive the growth of phytoplankton but using satellite data, the researchers of the study showed that the amount of water that leaves the melting glaciers in the Antarctic is the biggest contributor to the abundance of phytoplankton in the coastal polynyas.

The same goes for the snouts of «outlet» glaciers, where ice from the interior funnels through gaps in coastal mountain ranges, and where warming seawater has broken up clots of ice that can hold things up, like a logjam in a river.

«As a coastal city located on the tip of a peninsula, San Francisco is vulnerable to sea level rise, and human activities releasing greenhouse gases into the atmosphere cause increases in worldwide average temperature, which contribute to melting of glaciers and thermal expansion of ocean water — resulting in rising sea levels,» the ordinance reads.

Rising sea levels Ice sheets, glaciers, & snow in Greenland & Antarctica are melting Coastal communities most affected Saltwater will contaminate coastal aquifers Homes may be washed away Estuaries & wetlands are nurseries for many animals.

The gist is that the glaciers in Antartica and Greenland are melting so much faster than previously predicted that the global sea level will rise more than 10 feet in as little as 50 years, rendering many coastal cities uninhabitable.

The limited resolution of GRACE affects the uncertainty of total mass loss to a smaller degree; we illustrate the «real» sources of mass changes by including satellite altimetry elevation change results in a joint inversion with GRACE, showing that mass change occurs primarily associated with major outlet glaciers, as well as a narrow coastal band.

This change is likely to be most dramatic in Arctic coastal waters, which are rapidly freshening due to the melting of ice on glaciers and permafrost (McPhee et al. 2009), accelerating OA and Ωaragonite decline relative to the rates expected from anthropogenic CO2 alone (Tank et al. 2012).
