Sea levels to continue rising after Paris agreement emission pledges expire in 2030

Excerpts;

Sea levels will continue to rise around the world long after current carbon emissions pledges made through the Paris climate agreement are met and global temperatures stabilize, a new study indicates.

The new study is the first to quantify how much sea level would rise from the carbon emissions pledged under the Paris agreement. The researchers found that emissions released during the initial 15-year period of the agreement would cause sea levels to rise by about 20 centimeters by the year 2300…

“King tide” is the informal term generally used to describe an exceptionally high tide, which most often occurs when the Moon and the Sun are aligned and their gravitational pull on the Earth is at its strongest.NASA, AeroTech News

Excerpts;

The California King Tides Project helps people visualize future sea level by observing the highest high tides of today. You can help by taking and sharing photos of the shoreline during King Tides to create a record of the changes to our coast from sea level rise.

Find out at what time and how high the King Tides will be near you. Check back here in December to find a calendar of King Tides events hosted by local community organizations…

The more than 12,000 residents of this windswept Canadian archipelago are facing a growing number of gut-wrenching choices, as extreme climate change transforms the land and water around them. Season after season, storm after storm, it is becoming clearer that the sea, which has always sustained these islands, is now their greatest threat…

Our coastal cemeteries are falling into the sea; By Orrin H. Pilkey & William J. Neal
Cemeteries in coastal areas were not located with the expectation that they would flood or fall into the sea. But most of the world’s ocean and estuarine shorelines are eroding — some slowly like California’s rocky coasts, and others rapidly like the Carolinas’ barrier island coasts…

“Cape Shoalwater, Washington is the fastest eroding stretch of land on the west coast, maybe even the entire Western Hemisphere.” —Eddie Jarvis.

Excerpts;

Figure based on new analysis of coastlines is more than three times previous estimate.

More than three times more people are at risk from rising sea levels than previously believed, research suggests.

Land that is currently home to 300 million people will flood at least once a year by 2050 unless carbon emissions are cut significantly and coastal defences strengthened, says the study, published in Nature Communications. This is far above the previous estimate of 80 million…

The only answer to rising seas is to retreat; By Orrin H. Pilkey & Keith C. Pilkey; The News & Observer (10-18-2017)
Except for the timing, there is no controversy among scientists regarding sea level rise. Defending the coast and holding the shoreline in place ultimately will be futile. With a three-foot or a six-foot sea level rise, we will retreat, probably beginning within the next 50 years…

“Living Shorelines” Will Get Fast Track to Combat Sea Level Rise; Scientific American (07-06-2016)
As sea levels rise along U.S. coasts, it may soon get easier for people and local governments to obtain federal permits to build what are known as “living shorelines,” natural or nature-based structures designed to protect communities and infrastructure from extreme storms and flooding even as they protect habitat.

Now is the time to make peace with the ocean.The time is now to stop sandbagging, both physically with no more shore-hardening structures, and politically with no more exceptions to the intent of the rules, no more undermining existing legislation, and a return to enforcement…

Excerpts;

For African coastal cities, sea level rise and increasing storm frequency and intensity pose serious threats.

The reality is that the West, Central, East and Mediterranean coastal zones in Africa are very low-lying. Within these low-lying coastal zones are many of Africa’s largest cities: Dakar, Abidjan, Accra, Lagos, Dar es Salaam, Alexandria, Tripoli, and Cape Town…
