UPDATE: The Ocean in a High CO2 World

Posted On June 25, 2013 by

polar bearsPresident Obama’s plan to address climate change is a step in the right direction on the long road toward making real progress in reducing carbon pollution. There is no greater threat to the life on our planet than the effects of putting too much carbon into the atmosphere, and we are already seeing the impacts. It’s urgent, and we must act now.

The Arctic is experiencing the effects of climate change more than anywhere else, with air temperatures warming about twice as fast as the rest of the planet. Water temperatures are rising and seasonal sea ice is melting at a record-breaking pace.

As we have increased the amount of carbon pollution pumped into the air, the ocean has absorbed more and more of it, becoming 30 percent more acidic since the Industrial Revolution. This has a ripple effect up the food web and across livelihoods.

There is something we can do about it. The ocean should be at the center of our solutions to the rising threat of carbon pollution. You can learn more about Ocean Conservancy’s work on this issue in my blog, The Ocean in a High CO2 World:

Underwater Astonishments…and Why We Must Preserve Them

Posted On June 5, 2013 by

This video of oceanographer David Gallo‘s TEDTalk ‘Underwater Astonishments‘ highlights some of the most amazing ways creatures have adapted to life in the ocean.  It is being featured as part of TEDWeekends –- a curated series that introduces a powerful “idea worth spreading” and is a collaboration of TED and The Huffington Post.  This week’s TEDTalk is accompanied by an original blog post from David Gallo, along with new op-eds, thoughts and responses from the HuffPost community, myself included.

After watching the video, please read my companion opinion piece, “Preserving Our Underwater World” where I discuss why we cannot take the ocean’s resilience for granted, especially as we are saddled with an utterly uncertain climate future that is changing the ocean’s physical and biological characteristics right before our eyes.

The Fish We Need to Feed 9 Billion People

Posted On May 22, 2013 by

The following is an excerpt from a post that first appeared on National Geographic’s Ocean Views:

Smart fisheries management is a great place to start a conversation about putting the ocean at the center of the world’s biggest challenges.  This is because the most profitable type of fishing is sustainable fishing – better management helps fishermen and the ocean at the same time.

Sustainable fishing means keeping enough fish in the water to reproduce and ensure a bountiful catch in the future. It’s a balancing act, but sustainable fisheries are in everyone’s best interest – from fishermen to distributors to gear manufacturers to retailers to consumers. If you’re a fisherman and you want to pass on your traditions to the next generation, or you want to be able to make good money 10 years from now, the most profitable way to fish is sustainably.

Unfortunately, overfishing due to poor fisheries management remains a global problem that threatens ecosystem health and human survival. For example, without enough forage fish—small fish like anchovies, sardines, and squid—the larger predators, like tuna, that feed on them will start to disappear as well.

That matters because we are facing a future with 9 billion people on the planet, and with that future comes huge concerns for food security.

More Reasons a National Ocean Policy is a Big Deal

Posted On April 25, 2013 by

The following is an excerpt from a post that first appeared on National Geographic’s Ocean Views:

I recently joined Ocean Conservancy as its new CEO because I believe in one simple but very ambitious premise: the ocean must be at the very center of the key challenge of our time.

That challenge is how to meet the enormous resource demands of a rapidly growing global population without destroying the natural systems that sustain us. In every aspect of this challenge—food, energy, climate, and protection of our natural resources—our ability to manage impacts on the ocean will make the crucial difference in sustaining the resources that we need to survive.

This is why approaches that look at the big picture, like the Obama administration’s National Ocean Policy plan released last week, are exactly what we need to rise to this challenge.

What Does More Carbon Pollution Mean for the Ocean?

Posted On April 16, 2013 by

“Where do we start?” It’s a question that I’m asked every day in relation to the opportunities we have to put the ocean at the center of the most pressing issues of our time.

One of our readers, who is very concerned about increasing CO2 emissions, asked that question in a comment on my last blog, where I detailed how rising carbon pollution is the greatest risk to the ocean and the resources—food, water, air, energy—it provides to sustain us.

The first step we need to take is to find out more about the species, people and places that are already feeling the effects of increased carbon pollution. The ocean is absorbing more and more of our carbon emissions, and its waters are becoming more acidic as a result. Ocean acidity has already increased 30 percent in the past few decades, and we are starting to see real impacts on species that depend on calcium for their shells.

The Ocean in a High CO2 World

Shell-building animals like oysters and sea snails are having trouble building their shells as the ocean’s chemistry changes, and this has a ripple effect up the food web and across livelihoods.

It’s easy to take for granted the many ways that the ocean keeps us alive—it sustains much of the air we breathe, the food we eat, the water we drink and the climate that surrounds us. The complex ocean systems that produce these benefits—from currents and photosynthesis to food chains—are often chaotic and unpredictable at smaller scales, but at large scales they come together in a dynamic equilibrium to ensure that life can thrive.

One of the ocean’s most important life-giving functions is its absorption of carbon dioxide emissions. But we have increased the amount of carbon pollution pumped into the air, and in turn, the ocean has absorbed more and more of it. As a result, the ocean’s chemistry is changing—it has become 30 percent more acidic since the Industrial Revolution. There is no uncertainty or doubt about this; it is a simple and eminently replicable chemical process.

Several of the comments posted by our readers on my last blog focused on this growing concern. My answer to those comments is this: overall there is no greater threat to the life on our planet than the effects of putting too much carbon into the atmosphere, and ocean acidification is a very large part of the problem.

It is, simply put, the largest chemistry experiment ever attempted. It is happening now, and it has real impacts on people and local economies today. Shell-building animals like oysters and sea snails are having trouble building their shells in overly acidic waters, and this has a ripple effect up the food web and across livelihoods. These impacts are likely small compared to what could come if CO2 concentrations keep increasing under the current “business as usual” scenario. At a certain point, shell-building animals will not be able to produce calcium carbonate, with immeasurable effect on the entire food chain.

We’re working with the world’s top ocean acidification scientists to raise awareness about this growing threat and on solutions with the people on the front lines who are already being affected, from oyster growers in Washington state to mussel growers in Maine. In the weeks and months to come, we at Ocean Conservancy will dive deeper to take a very hard look at carbon pollution. For instance, what impact might the Keystone XL pipeline, if approved, have on the ocean? It’s a vitally important question to answer.

At Ocean Conservancy, we understand that the ocean is not just a victim—it must be the part of the solution. The way we manage the ocean and the decisions we make about fishing, shipping, energy extraction and production, and more have huge implications for the future of carbon emissions and the ocean’s continued ability to sustain life.

As we explore this critical issue, we will do so from an “ocean-centric” point of view—we must determine what management decisions and policies we can inform and work on with fishermen, shippers, drillers, windmill builders and oceanographers that can transform ocean health.

We would love to hear from you on this.  There are solutions to be found, and it will take all of our ideas, passion and ingenuity to get there.

Help Us Shape a Vision for a Healthy Planet

Posted On March 5, 2013 by

At the Ocean Conservancy, we’re working to ensure a healthy ocean because we know that the ocean sustains us. The oxygen we breathe, the protein we eat, the moderate climates we enjoy, the joys of fishing, boating, diving and surfing, the easy global transfer of goods, and even the water we drink—all of this is thanks to the ocean. If the ocean is healthy, so are we.

Keeping it healthy is not easy, however. The only thing growing faster than our population—2 billion more people by 2040—is our consumption. The world’s population is becoming richer, and our demand for protein, energy, minerals and more, is exploding. The ocean holds the key to satisfying much of that demand, and it is thus at the very center of the most pressing challenge of our time: how do we create prosperity for all without destroying the natural world that sustains us?

We can do this, but we must first awaken to what is truly needed. In the old days, being an environmentalist meant that we sought to clean up very specific messes.  As a child, I witnessed this when the first attempts were made to clean up the Rhine River, which was a cesspool at the time—and, against all odds, we succeeded to the point that salmon were re-introduced.

But now our job is much bigger, because the distinctions we once had in the environmental movement—among people working on the ocean, on air pollution, on biodiversity, on climate change, on land use, on natural resources—are increasingly meaningless. We know that the ocean sustains us at a very existential level and that all of these natural systems are interconnected.
