Sea level rising fast but just within natural range

December 13th, 2013 by University of Southampton

University of Southampton and the Australian National University researchers report that sea-level rise since the industrial revolution has been fast by natural standards and at current rates may reach 80 cm above the modern level by 2100 and 2.5 metres by 2200. The team used geological evidence of the past few million years to derive […]

Sea level likely to rise by 2 metres for each degree of global warming

July 15th, 2013 by Potsdam Institute for Climate Impact Research

Greenhouse gases emitted today will cause sea level to rise for centuries to come. The paper “The multimillennial sea-level commitment of global warming” published in the Proceedings of the National Academy of Sciences shows that each degree of global warming is likely to raise sea level by more than two meters in the future. While […]

Political & economic short-termism driving civilisation to destruction

March 29th, 2013 by University West

Climate scientists have shown through their research that the ongoing rise in global temperature will cause the sea level to rise, which will drown coastal communities, and cause severe weather, which will kill many people. So why don’t politicians act on these findings? Social scientist Stellan Vinthagen shows that today’s power relations prohibit change. The […]

Atlantic hurricane storm surges will increase with global warming

March 26th, 2013 by National Oceanography Centre

Extreme storm events of the magnitude of Hurricane Katrina will occur more frequently because of climate change, according to a study involving the National Oceanography Centre in Liverpool. The research, published in the paper ‘Projected Atlantic hurricane surge threat from rising temperatures‘ in ‘Proceedings of the National Academy of Sciences of the USA (PNAS) concludes […]

Current atmospheric C02 level must be reduced to protect coastal cities

January 3rd, 2013 by National Oceanography Centre

By comparing reconstructions of atmospheric CO2 concentrations and sea level over the past 40 million years, researchers based at the National Oceanography Centre, Southampton have found that greenhouse gas concentrations similar to the present of nearly 400 parts per million (ppm) were systematically associated with sea levels at least nine metres above current levels. The […]

West Antarctic ice sheet among the fastest-warming regions on Earth

December 23rd, 2012 by Ohio State University

Research published in the paper ‘Central West Antarctica among the most rapidly warming regions on Earth‘ in Nature Geoscience states that the western part of the ice sheet is experiencing nearly twice as much warming as previously thought. This discovery raises concern about the future contribution of melt water from Antarctica to sea level rise. […]

Greater Antarctic snowfall increases future ice loss and sea level rise

December 18th, 2012 by Potsdam Institute for Climate Impact Research

Earlier research suggested the Antarctic ice sheet might grow under climate change because global warming leads to more precipitation as warmer air holds more moisture. New research finds that stronger snowfall increases future ice discharge from Antarctica. The paper “Increased future ice discharge from Antarctica owing to higher snowfall” published in Nature shows that a […]

Warm sea currents undermining West Antarctic glaciers

December 11th, 2012 by University of Gothenburg

The ice sheet in West Antarctica is melting faster than expected. New observations published by oceanographers from the University of Gothenburg and the US may improve our ability to predict future changes in ice sheet mass. The research was published in the paper “Persistent inflow of warm water onto the central Amundsen shelf” in the […]

Satellite telemetry shows average global sea level rising 60% faster than IPCC projections

November 30th, 2012 by Potsdam Institute for Climate Impact Research

The rate of sea-level rise in the past decades is greater than projected by the latest assessments of the Intergovernmental Panel on Climate Change, (IPCC) while global temperature increases are in agreement with its best estimates. This is shown in the paper “Comparing climate projections to observations up to 2011” published in the journal Environmental […]

Greenland and Antarctica ice loss accelerating

November 29th, 2012 by University of Washington

Forty-seven research scientists from 26 laboratories have reconciled their measurements of ice sheet changes in Antarctica and Greenland during the past two decades and found that ice has been lost faster during the last decade. The results, published in the paper “A Reconciled Estimate of Ice-Sheet Mass Balance” in the journal Science, roughly halve the […]
