Sea level rise threatens larger number of people than earlier estimated

ScienceDaily: More people live close to sea coast than earlier estimated, assess researchers in a new study. These people are the most vulnerable to the rise of the sea level as well as to the increased number of floods and intensified storms. By using recent increased resolution datasets, Aalto University researchers estimate that 1.9 billion inhabitants, or 28% of the world's total population, live closer than 100 km from the coast in areas less than 100 meters above the present sea level. By 2050 the...

Rutgers University Study finds sea level rise in the 20th Century was fastest in 3,000 years

Environmental News Network: Global sea level rose faster in the 20th century than in any of the 27 previous centuries, according to a Rutgers University-led study published today. Moreover, without global warming, global sea level would have risen by less than half the observed 20th century increase and might even have fallen. Instead, global sea level rose by about 14 centimeters, or 5.5 inches, from 1900 to 2000. Thats a substantial increase, especially for vulnerable, low-lying coastal areas. The 20th-century...

10,000 Years Sea Level Rise From Human-Caused Climate Change

2016-02-14 16:50:00| Climate Ark Climate Change & Global Warming Newsfeed

Clean Technica: The sea level rise that will accompany unmitigated anthropogenic climate change will last for at least 10,000 years, according to new research published in the journal Nature Climate Change. What this means, is that many of the most highly populated areas of the globe - many of which are now expected to go under the waves over the next few hundred years - will still be underwater nearly 10 millennia from now. Even if emissions are rapidly curtailed and warming is kept below 2° Celsius (a very...

Climate: Land areas storing more water, slowing sea level rise

2016-02-13 08:40:00| Climate Ark Climate Change & Global Warming Newsfeed

Summit County: As crucial as it is for the future of humanity, calculating the rate of sea level rise has never been easy, and new measurements by NASA satellites have added a new twist to the equation. Careful study of the data from NASA`s twin NASA`s Gravity Recovery and Climate Experiment (GRACE) satellites helped show how climate-driven increases of liquid water storage on land have affected the rate of sea level rise. In the past decade, Earth`s land masses have soaked up an extra 3.2 trillion tons of water...
