Sentences with phrase «global sea level rise rate»

Between 1901 and 2010, global sea levels rose by 0.19 ± 0.02 m, albeit at varying rates and spatial distribution (Church et al. 2013)-- these past values (including their uncertainty) are potentially much smaller than those associated with future projections.

Each base's exposure is calculated based on the National Climate Assessment's midrange or «intermediate - high» sea level rise scenario (referred to in this analysis as «intermediate»), which projects a global average increase of 3.7 feet above 2012 levels, by 2100; and a «highest» scenario based on a more rapid rate of increase, which projects a global average increase of 6.3 feet.
