Blue carbon: A better tomorrow begins below

By: Kristin M. Kleisner and Jamie Collins

As we embark this year on the United Nations Ocean Decade, you may be hearing quite a bit about blue carbon. But what is it, and why is it so important for the future of our planet?  Well, the oceans play a critical role in trapping carbon, and they have absorbed about a third of all human-generated carbon emissions since the start of the Industrial Revolution. This is important because the carbon that human activity has released into the atmosphere acts as an accelerator of climate change.

When carbon is stored naturally in the various parts of ocean and coastal ecosystems — sequestering it, or taking it out of the atmosphere, where it could contribute to warming — we call it blue carbon. The blue carbon storage reservoir includes waters, sediments, and marine plants and animals. Unfortunately, loss of habitat, overfishing and other human impacts, including those from climate change, are reducing the ability of the oceans to trap carbon. That’s why we are exploring pathways to restore these benefits now and help to secure a better future for us all. You can learn more about blue carbon and some of the ways in which we may be able to restore key pathways using this interactive site. Read More »

Natural climate solutions cut a steady course through a sea of proposals for ocean carbon dioxide reduction

When it comes to slowing the warming of our planet, there is no substitute for immediate, dramatic reductions in anthropogenic greenhouse gas emissions. But emissions reductions alone won’t be enough to limit warming to the 1.5 degrees Celsius goal at the heart of the 2015 Paris Agreement, or even to the Agreement’s upper limit of 2 degrees Celsius. In fact, we’ll almost certainly need to complement emissions reductions with big investments in carbon dioxide removal, or CDR, to capture and lock away some of the carbon dioxide we’ve already emitted.

Seaweed to heal the planet

Seaweed forests and algal beds cover about 3.5 million square km of our planet — only about 1% of the ocean’s surface — but these amazing ecosystems generate benefits to people and nature far out of proportion to their size. Read More »

Collaborative research sheds light on creating climate-resilient multispecies fisheries

Worldwide, there is considerable interest in developing fishery management options that balance social, economic and ecological goals for multispecies fisheries. Ideally, fisheries management should strive not only to produce good yields from single stocks, but also to avoid serial depletion and prevent adverse impacts of fishing on marine ecosystems — a difficult, but achievable task.

As the Blue Economy blossoms, the fishing industry is being left behind. What can we do about it?

By Julia Rose and Christopher Cusack

The generation of goods and services on or for the oceans has been growing exponentially in recent years. Industries such as shipping, marine tourism, aquaculture and renewable energy contribute to a “Blue Economy” that employed 2.3 million Americans and generated $373 billion for the U.S. economy in 2018.

Maximizing benefits: considerations for oceans technology applications 

By Trudie Grattan and Melissa Mahoney

When you hear the phrase “oceans technology,” what comes to mind? Do you picture a futuristic device that’s cleaning up the Pacific Garbage Patch? Smart cameras to see a fishing vessel’s activity, fishing location and more? Read More »
