Sea Level Rise
Exceptional rise in ancient sea levels revealedScienceDaily.com | 06 Jun 2012
Since the end of the last ice age 21,000 years ago, our planet has seen ocean levels rise by 120 meters to reach their current levels. This increase has not been constant, rather punctuated by rapid accelerations, linked to massive outburst floods from the ice caps. The largest increase, known by paleoclimatologists as 'Melt-Water Pulse 1A', proved to be enigmatic in many respects.
Is California preparing for climate change?ScienceDaily.com | 04 Jun 2012
A majority of California's coastal planners and resource managers now view the threats from climate change as sufficiently likely that practical steps on the ground need to be taken to protect against growing threats, according to results from a new survey.
Effect of groundwater use: Using water from wells leads to sea level rise, cancels out effect of dam...ScienceDaily.com | 10 May 2012
As people pump groundwater for irrigation, drinking water, and industrial uses, the water doesn't just seep back into the ground -- it also evaporates into the atmosphere, or runs off into rivers and canals, eventually emptying into the world's oceans. This water adds up, and a new study calculates that by 2050, groundwater pumping will cause a global sea level rise of about 0.8 millimeters per year.
New Antarctic ice shelf threatened by warmingReuters | 09 May 2012
LONDON (Reuters) - Scientists are predicting the disappearance of another vast ice shelf in Antarctica by the end of the century that will accelerate rising sea levels.
Bangladesh's war against climate changeGuardian Unlimited | 09 May 2012
Devastating cyclones, floods and ruined crops have made Bangladesh 'the world's most aware society on climate change'Rebecca Sultan's life has been shattered twice in a few years. First, the 140mph winds of Cyclone Sidr ripped through her village, Gazipara, flattening houses, killing 6,000 people...
Greenland glaciers speed up, swelling rising seas: reportsReuters | 03 May 2012
WASHINGTON (Reuters) - Some of Greenland's glaciers are moving about 30 percent faster than they did 10 years ago, contributing to rising global sea levels, but that still may not be enough to reach the most extreme projections for 2100, scientists reported on Thursday.
Sea-level rises 'may not be as high as worst-case scenarios have predicted'Guardian Unlimited | 03 May 2012
Sea-level rises are unlikely to be as high as worst-case scenarios have forecasted, suggests new research which shows that Greenland's glaciers are slipping into the sea more slowly than was previously thought. But the scientists warned that ice loss still sped up by 30% and is driving rises in sea levels that endanger low-lying coasts around the world.
Geophysicists employ novel method to identify sources of global sea level riseScienceDaily.com | 26 Apr 2012
As the Earth's climate warms, a melting ice sheet produces a distinct pattern of sea level change known as its sea level fingerprint. Now, geophysicists have found a way to identify the sea level fingerprint left by a particular ice sheet, and possibly enable a more precise estimate of its impact on global sea levels.
Tanzania: Zanzibar Strives to Protect Forests, CoastAllAfrica.com | 22 Apr 2012
[Daily News] Zanzibar - Zanzibar department of environment with support from Norway has organized a workshop to raise awareness on the impact of climate change on the islands and forests.
Scientists pin down historic sea level riseReuters | 28 Mar 2012
LONDON (Reuters) - The collapse of an ice sheet in Antarctica up to 14,650 years ago might have caused sea levels to rise between 14 and 18 metres (46-60 feet), a study showed on Wednesday, data which could help make more accurate climate change predictions.
Greenland ice melt seen at lower temperatures: studyReuters | 11 Mar 2012
LONDON (Reuters) - The complete melt of the Greenland ice sheet could occur at lower global temperatures than previously thought, a study in the journal Nature Climate Change showed on Sunday, increasing the threat and severity of a rise in sea level.
Climate balancing: Sea-level rise vs. surface temperature change ratesScienceDaily.com | 18 Jan 2012
Engineering our way out of global climate warming may not be as easy as simply reducing the incoming solar energy, according to a climate scientists. Designing the approach to control both sea level rise and rates of surface air temperature changes requires a balancing act to accommodate the diverging needs of different locations.
Simultaneous ice melt in Antarctic and ArcticScienceDaily.com | 02 Dec 2011
A new article shows that the two hemispheres attained their maximum ice sheet size at nearly the same time and started melting 19,000 years ago. This simultaneous melting was presumably caused by changes in the global sea level and deepwater circulation in the Atlantic Ocean.
Melting ice sheets now largest contributor to sea level riseScienceDaily.com | 08 Mar 2011
The Greenland and Antarctic ice sheets are losing mass at an accelerating pace, according to a new satellite study. The findings of the study -- the longest to date of changes in polar ice sheet mass -- suggest these ice sheets are overtaking ice loss from Earth's mountain glaciers and ice caps to become the dominant contributor to global sea level rise, much sooner than model forecasts have predicted.
Climate change 'will wreak havoc on Britain's coastline by 2050'Guardian Unlimited | 06 Mar 2011
Millions living near the coast are likely to be hit by rising sea levels, erosion and storm surges, warns a new study by the Joseph Rowntree Foundation. On Benbecula, they know all too well that rising tides threaten the UK's coastline. For the 1,200 inhabitants of the small, low-lying island in...
Some Antarctic ice is forming from bottomScienceDaily.com | 03 Mar 2011
Scientists working in the remotest part of Antarctica have discovered that liquid water locked deep under the continent's coat of ice regularly thaws and refreezes to the bottom, creating as much as half the thickness of the ice in places, and actively modifying its structure. The finding, which turns common perceptions of glacial formation upside down, could reshape scientists' understanding of how the ice sheet expands and moves, and how it might react to warming climate, they say.
