California city cites sea level rise in fight against coastal power plant

2014-07-08 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed

KPCC: The city of Oxnard in Ventura County has taken tentative steps to block a proposed power plant in the coastal zone. Oxnard's developing debate over how to incorporate concerns about newly-identified risks into longstanding planning processes is one of the first in California, but it's unlikely to be the last. California law requires state, county, and local agencies to consider implications of a changing climate in planning. Along the coast, those impacts include sea level rise and storm surges...

Antarctic winds could accelerate sea level rise

2014-07-08 13:47:00| Climate Ark Climate Change & Global Warming Newsfeed

Blue and Green: Expected changes in Antarctic wind patterns may speed up global sea level rise, threatening coastal cities and low-lying countries around the world, a new study has warned. Climate scientists have already resigned to the fact that sea levels, driven by melting ice sheets and glaciers around the world, will rise. It will mean that entire countries will eventually be lost to the sea. However, now it is feared that coastal winds, which are thought to be strengthening because of a hole in the ozone...

Previous Greenland Ice Sheet Collapse Rose Sea Level up to 6 Meter

2014-06-26 22:32:00| Climate Ark Climate Change & Global Warming Newsfeed

Nature World: More than 400,000 years ago, a warming period pushed Greenland's ice sheet past its limit and raised global sea levels up to 6 meters, according to new research. The results may give us a glimpse as to what may happen as a result of Greenland's current climate-induced melting dilemma. Known as the Marine Isotope Stage 11, this exceptionally long warming period between ice ages resulted in a global sea level rise of about 6-13 meters above present, caused by changes in the Earth's orbit around...

Greenland Ice Sheet Collapse Linked To Sea Level Rise 400,000 Years Ago: Study

2014-06-26 22:18:00| Climate Ark Climate Change & Global Warming Newsfeed

RedOrbit: A new study suggests that a warming period more than 400,000 years ago pushed the Greenland ice sheet past its stability threshold, resulting in a nearly complete deglaciation of southern Greenland and raising global sea levels some 4-6 meters. The study is one of the first to zero in on how the vast Greenland ice sheet responded to warmer temperatures during that period, which were caused by changes in the Earth`s orbit around the sun. Results of the study, which was funded by the National...

Georgia marsh experiment catalogs threats from sea level rise

2014-06-08 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed

Savannah Now: In a stretch of marsh along the Altamaha River near Darien on Thursday, with 18-wheelers barreling by on nearby Interstate 95, researchers wove their way through a maze of narrow boardwalks to tend their new, long-term field experiment. Each in a straw hat to protect from the fierce noonday sun, students and a technician added salty water to one small plot, measured the plant growth in a neighboring area and captured gasses for analysis. Their aim is to chronicle the effects of sea level rise...
