As the biosphere continues to warm and the ocean acidifies, solving the global carbon problem becomes more critical each day. Keeping temperatures to survivable levels requires reducing emissions while at the same time working aggressively to absorb as much carbon dioxide as possible, using approaches that can nurture natural ecosystems and help vulnerable human communities flourish.

Blue Carbon: a diamond in the rough
Fish: the missing ingredient in addressing global malnutrition
One of the things I focus on in my role as a climate scientist is understanding the impact of climate change on ocean fish populations as well as better fishery management practices to help ensure the continued delivery of seafood and livelihoods for millions of people around the world. Critically, the world is confronted with the challenge of increasing access to healthy food for a population that is expected to reach 10 billion by 2050. This summer, as people around the world take to the beaches and coastlines for some relaxation and enjoyment, it’s valuable to remember the major role oceans have in supporting human sustenance.

Engaging Small-Scale Fishers in the U.N. Food Systems Summit
For nearly a decade, I’ve worked on sustainable fisheries management, traveling to small-scale fishing communities around the world to learn how best to build the capacity of local fishers, scientists and managers to ensure the sustainability of their fisheries. From Mexico to Myanmar, I’ve worked with communities to help them reach their goals so they are not catching too many fish and helping them select gears and fishing areas to ensure their fisheries aren’t damaging key habitats.

Charting a New Course Toward Sustainable Offshore Aquaculture
Americans import over 85% of all the seafood we consume — and half of that is from foreign aquaculture. That means when it comes to the majority of farmed fish we eat, we’re exporting our environmental footprint while missing out on the opportunity to create greater resilience and jobs for our coastal communities here in the U.S. Also lost is the opportunity to lead the way in developing best practices for sustainable production of healthy seafood that meets the most stringent environmental and health standards. This is most true in building a sustainable marine aquaculture industry.
Fisheries resilience in the Humboldt Current: one step closer to achieving sustainability

Evidence abounds showing that our world — and especially our seas — are changing. This is particularly notable in the Humboldt Current Large Marine Ecosystem, where we have seen changes in the distribution of fish stocks, temperature anomalies, wave surges, harmful algal blooms and much more. Yet, the Humboldt Current continues to be a source of fisheries productivity, livelihoods, economic development and food security for the two most important fishing nations in South America: Peru and Chile. The Humboldt Current unites these two countries, which is especially important as climate change impacts require a united front to combat them and a new way to manage fisheries.
Seaweeds to the rescue, redux
Recently, there has been a great deal of interest and even excitement about how seaweed might be able to help save us from climate change.
I appreciate the newfound exuberance for seaweed, and wholeheartedly agree that seaweeds do a lot for society and the planet. A similar awakening to the wonders of seaweed occurred in the 1980s, but it is now a distant memory. Let’s revisit the past so we can figure out how to create the conditions that will drive the restoration of seaweed forests and the expansion of seaweed farming at scale so they can contribute to carbon drawdown while benefiting people and nature.
