Since 1993, the rates of sea-level rise to the north and northwest of Australia have been 7 to 11 mm per year, two to three times the global average, and rates of sea-level rise on the central east and southern coasts of the continent are mostly similar to the global average. These variations are at [...]
Signal: sea level rise
Sea level rise accelerating
…John A. Church of Australia, and his collaborator Neil J. White analyze records from instruments called tide gauges, starting in the 19th century and running into the 21st, and they also incorporate the satellite measurements of sea level that have been available since 1993. The satellite record gives far more complete coverage of the ocean [...]
Ongoing sea level rise threatening $100 billion in U.S. naval bases
A report commissioned by the United States Navy concludes that climate change will pose profound challenges for the sea service in coming decades, including a need to secure Arctic shipping lanes, prepare for more frequent humanitarian missions and protect coastal installations from rising seas. The 15-month study, conducted by the National Research Council, accepts the [...]
Ice sheets melting faster than expected
Greenland and Antarctica’s ice sheets are shrinking more quickly, suggesting United Nations projections for sea-level rise are too conservative, a U.S. National Aeronautics and Space Administration-funded study said.From 1992 to 2009, the two regions lost on average 36.3 billion tons more ice every year than the previous year, scientists led by Eric Rignot at NASA’s [...]
Extreme tides fueled by sea level rise flood Marshall’s capital Majuro
Extreme high tides have flooded parts of the low-lying Marshall Islands capital Majuro with a warning Sunday of worse to come because of rising sea levels. Several areas of the city were flooded Saturday and forecasters predicted more to come on Sunday evening before the current high tide levels ease. Flooding of the Marshall Islands [...]
Antarctic ice sheet melt accelerating
Estimates of recent changes in Antarctic land ice range from losing 100 Gt/year to over 300 Gt/year. Because 360 Gt/year represents an annual sea level rise of 1 mm/year, recent estimates indicate a contribution of between 0.27 mm/year and 0.83 mm/year coming from Antarctica. There is of course uncertainty in the estimations methods but multiple [...]
Ancient Roman fish tanks submerged by sea level rise
Archaeological discoveries that shed light on ancient sea level are prized finds for the experts in this field. One of the most compelling studies of recent years was carried out by an Australian scientist named Kurt Lambeck, who worked with colleagues in Italy. They focused on ancient fish tanks built at the edge of the [...]
Sea level rise approaching ground water in South Florida
Planning for the affects of global warming on our coastline. That’s what the South Florida Water Management district mapped out Tuesday afternoon. According to experts, our state is very vulnerable to the affects of climate change. You won’t see any structures built any time soon in reaction to global warming, but it’s on the radar. [...]
NASA’s Climate Time Machine
A series of visualizations from NASA show how some key indicators of climate change have changed in recent history.
