, the warming could reach a tipping point that would result in several feet
of global sea level rise by the end of the century.
It adds concrete evidence that dramatic changes are underway in this part of our planet, which has enough ice to raise
global sea levels by more than a metre.
This is reassuring, because if the ice cap did melt completely in the near future, it would
raise global sea levels by 60 metres.
In order to use tidal gauges to reliably estimate
global sea level changes, researchers have to successfully separate the components of shifting land heights and local sea level variability from any global trends.
I knew that this was happening, and thought that the flooded streets would make a great backdrop for my video
on global sea level rise.
Human -
caused global sea level rise likely accounts for at least two - thirds of the increase in nuisance flooding days from 1955 - 1984 to 1985 - 2014.
The melting of glaciers will affect people around the world, their drinking water supplies, water needed to grow food and supply energy, as well
as global sea levels.
This is why it is such an important setting to assess what may happen elsewhere later in this century,
when global sea level rise accelerates.
If global sea levels are rising due to thermal expansion, may we not reasonably conclude that the planet's diameter is increasing?
There is enough ice in the glaciers in the region to
push global sea levels up by more than 10 feet if they all melted, the scientists say.
The biggest difficulty in using tidal gauges to
study global sea level trends is separating local changes from global changes.
One of the most devastating potential impacts of global climate change is a
large global sea level rise over the coming century and beyond.
Nevertheless such variability induced by winds or currents may give a false impression of
global sea level fluctuations in analyses of tide gauge data.
The island nation's future is under threat from
anticipated global sea level rise, with many of its islands already suffering from coastal erosion.
They contain enough ice to
raise global sea level by 4 feet (1.2 meters) and are melting faster than most scientists had expected.
Areas experiencing little - to - no change in mean sea level are illustrated in green, including stations consistent with
average global sea level rise rate of 1.7 - 1.8 mm / yr.
Since 1992, the rate
of global sea level rise measured by satellites has been roughly twice the rate observed over the last century, providing evidence of acceleration.
The average annual rate of
global sea level rise accelerated from 1993 - 2008, increasing 65 - 90 percent above the twentieth century average.
The «zoo» of
global sea level curves calculated from tide gauge data has grown — tomorrow a new reconstruction of our US colleagues around Carling Hay from Harvard University will appear in Nature (Hay et al. 2015).
Drews received the award for his project Be: Wise, which investigates how the potential disintegration of Antarctic floating ice shelves could contribute to increased ice flow from inland glaciers, and a resulting rise in global sea level [1].
Reconstruction of
global sea levels since the late 1800s (until the satellite era beginning in 1993) relies uniquely on the tide gauge record.
