  • Global warming and sea level rise

    A new review analyzing three decades of research on the historic effects of melting polar ice sheets found that global sea levels have risen at least six meters, or about 20 feet, above present levels on multiple occasions over the past three million years. What is most concerning, scientists say, is that amount of melting was caused by an increase of only 1-2 degrees (Celsius) in ...

  • Rising Sea Levels – The New Reality

    Water may be flowing from the Greenland icecap and into the sea more quickly than anybody expected. It doesn’t mean that global warming has got conspicuously worse: rather, researchers have had to revise their understanding of the intricate physiology of the northern hemisphere’s biggest icecap. Climate calculations Since ...

  • We will need to adapt to rising sea levels

    “The good news is that a recent concentration of science resources is improving our insight into ocean and ice dynamics, and scientific measurement of the rate of sea-level rise,” says the book’s lead editor, CSIRO Fellow and oceanographer Dr John Church. “The way the world responds to climate change will become increasingly reliant on a sophisticated integrated ...

  • Survey: house buyers response to sea level rise

    According to CSIRO researcher Dr Nick Abel, the survey will help local and state governments make policy decisions on future coastal property and infrastructure developments. "We are asking people about what they think about purchasing properties in coastal areas," Dr Abel said. "We are also interested in their perspectives on sea level rise and how this influences their choices in purchasing ...

  • EPA releases report on sea level rise

    The US Environmental Protection Agency, in collaboration with other agencies, has released a report that discusses the impacts of sea level rise on the coast, coastal communities, and the habitats and species that depend on them. The report, Coastal Sensitivity to Sea-Level Rise: A Focus on the Mid-Atlantic Region, examines multiple opportunities for governments and coastal communities to plan ...

  • King tides – a glimpse of future sea level rise

    “By 2060 to 2070 we could be experiencing tides of at least this magnitude every month, rather than just twice a year due to climate-change induced sea level rise,” says a research scientist with CSIRO’s Climate Adaptation National Research Flagship, Dr Kathy McInnes. King tides are natural events that happen twice a year. The tides predicted for many parts of the east coast between 8am and ...

  • Sea-level changes – 50 meters high and rising

    Burning all of the world’s available fossil-fuel resources would result in the complete melting of the Antarctic ice sheet, a new study published in Science Advances shows. The Antarctic ice masses store water equivalent to more than 50 meters of sea-level rise. The new calculations show that Antarctica’s long-term contribution to sea-level rise could likely be restricted to a few ...

  • Unsustainable water consumption contributes to sea level rise

    The global sea level is rising, yet only part of that rise can be attributed to the effects of climate change. New research has calculated that human impacts on terrestrial water storage make up around 42% of total sea level rise, in particular, the extraction of groundwater that eventually makes its way to the ocean. Tidal measurements have revealed that the global sea level rose by 1.8mm per ...

  • B.C. releases new sea level rise report

    A new report released by the B.C. Government shows governments will need to continue working together to meet the challenge of climate change and rising sea levels over the next 90 years and beyond. The report, Climate Change Adaption Guidelines for Sea Dikes and Coastal Flood Hazard Land Use, shows that sea ...

  • Rising sea levels threaten islanders with displacement

    A significant rise in sea levels due to global warming could result in the loss of species and habitats in the coastal areas of more than a thousand islands in South-East Asia and the Pacific region, leading to the potential displacement of many ...

  • Indian Ocean sea levels `rising at different rates`

    Mapping variations in regional sea level changes of different parts of the Indian Ocean could help developing countries better adapt to the effects of climate change, according to a study published in Nature Geoscience last week (11 July). Researchers from the University of Colorado, United States, identified distinct patterns of sea-level rises using observational and satellite data combined ...

  • When sea levels rise, damage costs rise even faster

    Damages from extreme events like floods are even more relevant than the mean sea level itself when it comes to the costs of climate impacts for coastal regions. However, while it is now rather well understood how sea-levels will rise in the future, only small progress has been made estimating how the implied damage for cities at the coasts will increase during the next decades. A team of ...

  • Modelling effects of sea level rise in Northern Gulf of Mexico

    NOAA has awarded USD750,000 for the first year of an anticipated USD3 million research investment to develop the information and tools critically needed to plan for sea level rise and other consequences of climate change along more than 300 miles of the northern Gulf of Mexico's shoreline. The study team, led by Scott Hagen, Ph.D., of the University of Central Florida, will develop sea ...

  • Global sea-level rise at end of last ice age

    Southampton researchers have estimated that sea level rose by an average of about 1 metre per century at the end of the last Ice Age, interrupted by rapid ‘jumps' during which it rose by up to 2.5 metres per century. The findings, published in Global and Planetary Change, will help unravel the responses of ocean circulation and climate to large inputs of ice-sheet meltwater to the world ...

  • Mangroves can cope with sea level rise by increasing soil height

    A new report by The Nature Conservancy and Wetlands International shows that mangroves can adapt to rising sea levels by building up soils in some locations, allaying fears that mangroves may be lost as sea levels rise. ...

  • Global sea level rise monitoring secured for next decade

    The transatlantic Jason-3 Programme has now been approved by EUMETSAT Member States thus ensuring a continuation of the series of measurements made by the Jason-2 satellite and its predecessors in support of meteorology, operational oceanography and in particular the monitoring of the sea level trend, a key indicator of climate change. Nineteen EUMETSAT Member States have agreed to subscribe to ...

  • Sea levels to rise by one metre in the next 100 years?

    Rising sea levels will have dramatic consequences for many coastal areas around the world. A new study suggests that over the next 100 years, sea levels could rise to a metre higher than current levels, a rate faster than at any time during the past 2000 years. The rise predicted by this study is three times higher than the projections of the Intergovernmental Panel on Climate Change (IPCC)1. In ...

  • Study predicts maximum sea level rise close to one meter by 2100

    A new study of sea level fluctuations over the last 22,000 years is the latest to predict that rising seas could reach close to one meter by the end of this century, consistent with the most recent sea level projections made by the Intergovernmental Panel on Climate Change (IPCC). The estimate, published July 26 in the journal Nature Geoscience, is not as dire as the three-meter (nine-foot) rise ...

  • Tropical nations to see above average sea-level rises

    Coastal areas in the tropics may see some of the largest sea-level rises due to take place this century because of climate change, according to a study. This would particularly affect the Indian Ocean and Western ...

  • Sea level rises could far exceed IPCC estimates

    Could our coastlines disappear underwater much sooner than we think? The controversial view that sea levels could rise at a rate of more than 1 metre per century has found support from a new study of a long-melted ice sheet. In reconstructing the events at the end of the last ice age, Anders Carlson of the University of Wisconsin-Madison and colleagues found that the Laurentide ice sheet, which ...
