Melbourne -
A report from an Australian think tank has predicted massive climate shifts will effectively crash “civilisation” (This mess is a civilisation?) by 2050. That prediction may be a bit underdone, in several ways

Salisbury -
Coastal properties have long been in high demand, offering stunning views of the ocean at a premium price tag. With rising sea levels and increased coastal flooding, how concerned should property owners be about property values?
|
Greenland's ice is melting faster than scientists previously thought - and this will likely lead to faster sea level rise -thanks to the continued, accelerating warming of the Earth's atmosphere, a new study has found.
|
|
Scientists are meeting in the Azores this week to share findings on how satellites have revealed changes in the height of the sea, ice, inland bodies of water and more. Much of the meeting's focus will be on sea level rise.

|
Military leaders in South Carolina are preparing for rising sea levels while partisans dispute whether it's the effect of global warming. But that's because they are seeing the effects of climate change.
|
|
Thousands of miles of buried fiber optic cable in densely populated coastal regions of the United States may soon be inundated by rising seas, according to a new study.
|
|
In 80 years the rising seas’ cost could be $14 trillion a year globally, with the oceans possibly nearing two meters (6.5 feet) above their present levels, according to new research.
|
|
Sea level rise in the lower 48 states, primarily driven by climate change, is projected to worsen tidal flooding, putting as many as 311,000 coastal homes at risk of chronic flooding within the next 30 years.

|
The melting of Antarctica is accelerating at an alarming rate, with about 3 trillion tons of ice disappearing since 1992, an international team of ice experts said in a new study.
|
|
People living along the U.S coast may see flooded sidewalks and streets more frequently this year due, in part, to El Nino conditions that are predicted to develop later this year, and from long-term sea level rise trends.
|
|
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.

The Nuclear Regulatory Commission has authorized its staff to issue Combined Licenses for Florida Power and Light’s Turkey Point site in Florida. FPL now has permission to build and operate two AP1000 reactors at the site, about 25 miles south of Miami.

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.

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.
|
|
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.
|
|
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.

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.
|
|
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.

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?

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.
|
|
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.
|
|
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.”
|
|
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 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.

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.

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.

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.
