Scientist investigates changing sea levels
The sea level has been rising by an average of 3.1 millimetres a year since 1993. Long-term measurements recorded since the start of the 20th century indicate an acceleration in the averaged sea level change. Coastal flooding ...
Greenhouse gases soar; no signs warming is slowed
(AP) -- Heat-trapping greenhouse gases in the atmosphere are building up so high, so fast, that some scientists now think the world can no longer limit global warming to the level world leaders have agreed upon as safe.
Ocean climate change damage to cost $2 trillion
Greenhouse gases are likely to result in annual costs of nearly $2 trillion in damage to the oceans by 2100, according to a new Swedish study
Princeton geoscientists report Greenland ice sheet melting rate is increasing
Arctic sea ice hits record low
Arctic sea ice has reached its lowest winter point since satellite observations began in the late 1970s, raising concerns about faster ice melt and rising seas due to global warming, US officials said Thursday.
NASA satellites detect pothole on road to higher seas
Like mercury in a thermometer, ocean waters expand as they warm. This, along with melting glaciers and ice sheets in Greenland and Antarctica, drives sea levels higher over the long term. For the past 18 years, ...
Antarctic octopus tells story of ice-sheet collapse
Scientists have long been concerned that the massive West Antarctic Ice Sheet could collapse if global temperatures keep climbing. If it did, sea levels are predicted to rise by as much as five meters.
A new approach to assessing future sea level rise from ice sheets
Future sea level rise due to the melting of the Greenland and Antarctic ice sheets could be substantially larger than estimated in Climate Change 2007, the Fourth Assessment Report of the IPCC, according to new research from ...
High CO2 spurs wetlands to absorb more carbon
(Phys.org) —Under elevated carbon dioxide levels, wetland plants can absorb up to 32 percent more carbon than they do at current levels, according to a 19-year study published in Global Change Biology from t ...
Researcher dives into archaeology's next frontier
As a specialist in prehistoric underwater archaeology, Dr Jonathan Benjamin looks at rising sea levels a little bit differently from most people.
Earth's interior cycles contributor to long-term sea-level and climate change, scientists conclude
Ancient rises in sea levels and global warming are partially attributable to cyclical activity below the earth's surface, researchers from New York University and Ottawa's Carleton University have concluded ...
Warming of two degrees inevitable over Canada: study
(PhysOrg.com) -- Even if zero emissions of greenhouse gases were to be achieved, the world’s temperature would continue to rise by about a quarter of a degree over a decade. That’s a best-case ...
Paleoclimate record points toward potential rapid climate changes
(PhysOrg.com) -- New research into the Earth's paleoclimate history by NASA's Goddard Institute for Space Studies director James E. Hansen suggests the potential for rapid climate changes this century, including ...
Study shows global glaciers, ice caps, shedding billions of tons of mass annually
Earth's glaciers and ice caps outside of the regions of Greenland and Antarctica are shedding roughly 150 billion tons of ice annually, according to a new study led by the University of Colorado Boulder.
