A new study has shown that not only does melting ice contribute more to rising sea levels than thermal expansion, but that ocean levels are likely to continue rising well after the warming of the atmosphere stabilises.
“If you put an ice cube in a warm room, it will melt in several hours. But if you put an ice cube in a cup of warm water, it will disappear in just minutes.”
A group of scientists collected from the United States, United Kingdom and Australia, have taken a look below the Aurora Subglacial Basin in the East Antarctic Ice Sheet and found some of the largest fjords on Earth.
Focusing their attention on the collapse of the Barents ice sheet which took place some 140,000 years ago, scientists from Bangor University and the University of Sheffield have used a computer climate model to understand how different states of freshwater entering the oceans affect the circulation of the oceans.
More and more the history of our planet is being used to help us understand the future of our planet. Scientists from Boston University have recently published their findings of the mid-Pliocene climate optimum period 3 million years ago, and the similarities it could hold for the future centuries of our planet.
New evidence provided by researchers flying over East Antarctica’s Gamburtsev Mountain’s between November 2008 to January 2009 has shown that there is ice forming at the bottom of the massive ice sheets that cover Antarctica, as well as on the top.
In many climate models and scientists’ theories the West Antarctic ice sheet is expected to melt over the coming hundreds of years and raise the sea levels. Much of this is based on the theory that during the last interglacial period the ice sheet must have melted in order to raise the sea levels as much as they had been. However new research suggests that the West Antarctic ice sheet may be more stable than had been previously realised.
Cambridge University has released another film in their ‘Cambridge Ideas’ series entitled ‘This Icy World’ shown below. The small film looks at the contribution of Greenland to global sea level … [Read full article]
With warming temperatures worldwide much speculation has been focused on how the Antarctic and Greenland ice-sheets will react. Hotter temperatures, in theory, should be bad for ice, but according to … [Read full article]
New research from Victoria University in Australia has revealed new findings pointing to why the Antarctic ice sheets have melted in the past, and how they might be most affected … [Read full article]
According to a recently published paper in the journal Geophysical Research Letters (Khan et al), Greenland’s ice mass loss has been accelerating and is now spreading up along its northwest coast, with data indicating the start of this acceleration to be late 2005.
