Sea level rise has long been expected to be an ongoing and worsening problem for U.S. coasts, but scientists have found that some areas are experiencing "unprecedented" levels of rising seas, raising concerns about the fate of already vulnerable communities. A new study published in Nature Communications on Monday found that since 2010, sea level rise along the nation's Southeast and Gulf coasts has ramped up dramatically, hitting rates that are "unprecedented in at least 120 years." Since 2010, scientists from Tulane University have found that sea levels in those regions have increased by about half an inch every year....

The saga of San Francisco's sinking Millennium Tower continues, as the structure's movement has now created a 1-inch gap between the main tower and a 12-story podium, according to reporting by the San Francisco Chronicle.

Rising seas could affect three times more people by 2050 than previously thought, according to new research, threatening to all but erase some of the world’s great coastal cities. The authors of a paper published Tuesday developed a more accurate way of calculating land elevation based on satellite readings, a standard way of estimating the effects of sea level rise over large areas, and found that the previous numbers were far too optimistic. The new research shows that some 150 million people are now living on land that will be below the high-tide line by midcentury. SNIP

Say I want to raise the sea level one inch, how much water do I need?

Two Bay Area counties sued 37 oil, gas and coal companies Monday asserting the companies knew their fossil fuel products would cause sea level rise and coastal flooding but failed to reduce their greenhouse gas pollution. The lawsuit was part of a coordinated litigation attack by Marin, San Mateo County and the city of Imperial Beach.

CHICAGO (AFP) – While a collapse of the West Antarctic ice sheet will have devastating impacts on global sea levels, a study published Thursday found the anticipated impact has been seriously overestimated. Using new measures of the ice sheet's geometry, British and Dutch researchers predict its collapse would cause sea levels to rise by 3.2 meters (11 feet) rather than previous estimates of five to seven meters. However, the study published in the journal Science found that even a one meter rise in sea levels would be significant enough to weaken the Earth's gravity field in the southern hemisphere and...

The global sea level looks set to rise far higher than forecast because of changes in the polar ice-sheets, a team of researchers has suggested. Scientists at a climate change summit in Copenhagen said earlier UN estimates were too low and that sea levels could rise by a metre or more by 2100. The projections did not include the potential impact of polar melting and ice breaking off, they added. The implications for millions of people would be "severe", they warned. Ten per cent of the world's population - about 600 million people - live in low-lying areas. The UN's...
