A new study has revealed a previously undocumented process where melting glacial ice sheets change the ocean in a way that further accelerates the rate of ice melt and sea level rise.

Op-Ed: Dumb move of the week — NRC approves two nuke plants in Florida

Researchers launch web-based sea level report cards

Researchers are launching new web-based 'report cards' to monitor and forecast changes in sea level at 32 localities along the U.S. coastline from Maine to Alaska. The report cards will be updated each year, with projections out to the year 2050.

Parts of California's Bay Area sinking faster than expected

San Francisco - Current global projection maps depicting sea level rise are what city managers and planners depend on for future development, however, coastal subsidence has very seldom been considered in making these projections. The Bay Area is a good example.

Robots en route to Antarctica to study underside of ice shelves

It has become increasingly common to see cliff-sized chunks of glacial ice falling into the Southern Ocean, suggestive of a warming climate. But scientists don't know what's going on beneath Antarctica's ice sheets., so they are preparing to find out.

NASA tool will help coastal cities plan for rising ocean levels

With rising sea levels being one of the most noticeable results of climate change, being able to locate and pinpoint which glaciers and ice sheets are contributing to local sea level rises will be very helpful in how we prepare for the future.

Alabama's ancient underwater cypress forest giving up its secrets

Off the coast of Alabama, in the Gulf of Mexico, lies a relic from our planet's past. Submerged under 60 feet of water is an ancient cypress forest, about 60,000 years-old, preserved in place — the trees still rooted in the dirt from millennia ago.

NASA's 'OMG Mission' - Greenland's glaciers are melting fast

Due to climate change, glaciers in Greenland are melting faster than previously thought. A new video released today by NASA shows how the agency is keeping track of the magnitude of the changes occurring in the Arctic, now being measured in feet per day.

Trump tells mayor of sinking island not to worry over sea-level

Tangier - After a story about disappearing Tangier Island aired on television June 9, President Trump made it a point to telephone the island's mayor, assuring him that sea level rise was nothing to worry about. Hmm, does Trump know something we don't know?

Op-Ed: Climate talks begin in Bonn — The stakes have never been higher

UN negotiators are meeting in Bonn, Germany this week to discuss and work out a plan to implement the Climate-Rescue Paris Agreement. The stakes have never been higher - Yet one important member nation is threatening to pull out of the agreement.

Two new studies: Surface of Antarctica 'swimming in meltwater'

For the first time ever, the network of streams, ponds, and lakes across Antarctica's surface have been mapped, and the extent of the water flow is astounding and worrying to scientists.

Sacramento - Rising ocean levels are impacting low-lying coastal regions around the world, and along the West Coast of the United States this winter, we have seen the results of sea-level rise in the extreme high tides and flooding that hit California.

Scientists discover over 40 preserved shipwrecks in Black Sea

A group of maritime archaeologists studying sea level rises in the Black Sea during the last Ice Age uncovered over 40 shipwrecks this year, declaring their find as a “complete bonus.”

Sea levels rising faster than they have in past 27 centuries

In a new study, scientists say it is "extremely likely' that sea levels rose faster in the 20th century than any any time in the preceding 2,700 years, and the rise in sea levels has been even faster in the last two decades.

El Niño and La Niña will intensify coastal hazards across Pacific

El Nino and La Nina climate circulation events are predicted to become more severe, causing an increase in the number and intensity of storms, leading to extreme coastal erosion and flooding, says a multi-agency study.

Op-Ed: New study says climate will cause massive population displacement

Sydney - A Norwegian Refugee Council (NRC) survey has found that more people are displaced by natural events and climate-related phenomena than all the wars on Earth combined. The NRC operates the Internal Displacement Monitoring Centre in Geneva.

Underwater robot sheds new light on Antarctic sea ice

Cambridge - A collaborative effort involving scientific teams from the UK, U.S. and Australia has produced the first detailed, high-resolution 3-D maps of Antarctic sea ice with the help of an underwater robot.

North Carolina's 'climate change battle' rages on

It started in 2011, when Willo Kelly, a resident of the Outer Banks in North Carolina attended a meeting held in a government conference room. There, she learned that by the end of the century, sea levels along the coast would rise as much as 39 inches.

America's birthplace in danger of disappearing

Jamestown - U.S. Secretary of the Interior Sally Jewell toured Jamestown Island on Thursday, guided by National Park rangers. She got a first-hand look at America's first permanent English settlement in North America. She also saw that some areas are now underwater.

‘Unstoppable' loss of Antarctic glaciers prompts sealevel warning

Irvine - The rapidly melting West Antarctic Ice Sheet is in an irreversible state of decline according to the latest NASA study. As a result, the "ice-dam" preventing glaciers in the area melting into the sea will ultimately disappear.

West Antarctic ice sheet collapsing

A massive glacier system has started collapsing in West Antarctica due to global warming, and studies by two different teams of scientists claim the collapse will result in a significant rise in sea levels worldwide.

Decades of rising seas predicted as huge Antarctic glacier melts

Cambridge - Pine Island Glacier, part of the West Antarctic Ice Sheet and the biggest single contributor to rises in global sea levels, continues to melt at record rates. The melt could continue for decades, according to new research.

Op-Ed: With sea levels rising rapidly, tough decisions for humanity

If a recent scientific study is correct on the human-induced impact on arctic ice melt and sea level rise, humanity is facing two grim choices - expensive urban planning options or managing our core overpopulation problem.

Op-Ed: Not cheap and very real — Australia evaluates sea level threats

Australia’s major cities are all coastal. Confirmed sea level rises, combined with ongoing severe coastal erosion, have been worrying people for the last decade. It’s now looking like the famous Australian beachside lifestyle is riding on the tides.

GRACE satellites, paleo data predict sea level rise of 5 metres

A new finding that the eastern Antarctic ice sheet is losing a lot more ice than previously thought has re-ignited debate over projections for sea level rises. The ice sheet, if it disappeared, could add 5 metres to sea levels.
