GRID-Arendal Highlights Blue Forests Project Launch

Leave a comment

December 2014: GRID-Arendal's interim marine newsletter highlights the launch of the Global Environment Facility's (GEF) Blue Forests Project, which will explore how to harness the value of carbon and other coastal ecosystem services to improve ecosystem management.

The Blue Forests Project aims to increase recognition of the role of mangroves, seagrasses and saltmarshes in climate change mitigation and adaptation. It will also address knowledge gaps on the role of blue forests in storing and sequestering carbon and sheltering towns from storms. The project will be implemented in Ecuador, Indonesia, Kenya, Madagascar, Mozambique and the United Arab Emirates (UAE) as well as in a to-be-determined location in Central America.

The newsletter also highlights: the Norwegian Blue Forests Network, an initiative that focuses on harnessing the potential of blue forests to capture and store atmospheric carbon as well as other ecosystem services; and a GRID-Arendal and Blue Climate Solutions report, ‘Fish Carbon: Exploring Marine Vertebrate Carbon Services.' The report highlights the potential of marine vertebrates to address climate change and prevent global biodiversity loss and presents eight “fish carbon” mechanisms.

GRID-Arendal also announced that it will begin producing a common newsletter for all its programmes beginning in January 2015, making this newsletter the last one focused solely on marine issues. More

Small Caribbean Island Shows Bold Ocean Leadership: Barbuda Overhauls Reef and Fisheries Management for Sustainability

On August 12th, Barbuda Council signed into law a sweeping set of new ocean management regulations that zone their coastal waters, strengthen fisheries management, and establish a network of marine sanctuaries.

This comes after seventeen months of extensive community consultation and scientific research supported by the Waitt Institute. With these new policies, the small island of Barbuda has become a Caribbean ocean conservation leader and global role model. The regulations establish five marine sanctuaries, collectively protecting 33% (139 km2) of the coastal area, to enable fish populations to rebuild and habitats to recover. To restore the coral reefs, catching parrotfish and sea urchins has been completely prohibited, as those herbivores are critical to keeping algae levels on reefs low so coral can thrive. Barbuda is the first Caribbean island to put either of these bold and important measures in place.

“This will definitely benefit the people of Barbuda, and Antigua as well. No part of this is meant to hurt fishers. It’s the reverse – ensuring that they have a livelihood that will last in perpetuity,” said Arthur Nibbs, Chairman of the Barbuda Council and Antigua and Barbuda Minister of Fisheries.

Caribbean-wide, communities are seeing declines in the health of coastal ecosystems and fish populations. This negatively impacts economies, food security, and cultures. Visionary action like that shown in Barbuda is needed to manage the ocean sustainably, profitably, and enjoyably, for this and future generations. The coastal zones and fishing regulations reflect stakeholders’ priorities and are the outcome of a community-driven, science-based, and consensus-seeking process aiming to balance current and future needs to use ocean resources.

Which U.S. City Will Be the First Submerged by Climate Change?

Leave a comment

A new Climate Central report shows which U.S. cities’ fates are locked in by sea-level rise. The long list of 1,400 cities includes not only obvious coastal candidates like Miami and New Orleans, but also inland cities such as Sacramento. They’re doomed to drown by 2100 even if carbon emissions immediately—like right now—drop to zero.

Representative Henry Waxman (D-CA), a longstanding climate champion, tells TakePart: “As this report makes clear, climate change is no longer an issue for ‘later.’ Climate change is already affecting the United States and the window for effective action is closing fast. We must act now to protect the planet for our children and future generations.”

Ben Strauss, one of the scientists behind the new report, began with a study that found for every degree Fahrenheit of global warming due to carbon pollution, global average sea-level will rise by about 4.2 feet in the long run. When multiplied by the current rate of carbon emissions, and the best estimate of global temperature sensitivity to pollution, this translates to a long-term sea-level rise commitment that is now growing at about one foot per decade. Strauss then analyzed the growth of the locked-in amount of sea-level rise and plotted it against a map of the United States.

Carbon pollution to date has already locked in more than four feet of sea-level rise past today’s levels, Strauss finds. That’s enough, at high tide, to submerge more than half of today’s population in 316 coastal cities and towns, home to 3.6 million people, in the lower 48 states.

“We have two sea levels: the sea level of today, and the far higher sea level that is already being locked in for some distant tomorrow,” Strauss writes.

Rising tides have already harmed some coastal towns.

“In Rhode Island, we’ve already seen almost 10 inches of sea-level rise at the Newport tide gauge since the 1930s, making coastal communities more vulnerable to floods, erosion, and the kind of property damage we saw during Hurricane Sandy. We must take immediate steps to limit the carbon pollution that is contributing to sea-level rise, and help coastal areas prepare for new realities,” Senator Sheldon Whitehouse tells TakePart.

To the surprise of absolutely no one who has seen An Inconvenient Truth, Florida is the most threatened state. Louisiana, North Carolina, and New Jersey are also high on the list. Strauss didn’t consider the impact of armoring or defending cities in preparing his report, but notes that New Orleans may be defensible through sea walls, while Miami is indefensible because of its porous bedrock geology.

Although California’s Sacramento and Stockton are thought of as inland cities, they’re connected to the Pacific Ocean through the Sacramento-San Joaquin Delta, a complex maze of marshes and levees. By 2040, 25 percent of Stockton will be underwater at high tide. By 2060, the same will be true of Sacramento, California’s state capitol. Coastal California cities such as Huntington Beach, the original Orange County Surf City, and Palo Alto, home of Stanford University, will likewise be inundated.

Other cities projected to be 50 percent underwater: Galveston, Texas, by 2030; Norfolk, Virginia; and Coral Gables, Florida, by 2044. More
