Oceanography

Where does climate change stand in 2026? This week on Oceanography, we’re bringing you a special crossover from Green Frequency: a new Earth Radio show from Pine Forest Media exploring environmental science, policy, and the systems shaping our planet. In this episode, climate scientist Dr. Claudio Piani joins a conversation on where we actually stand today: global emissions trends, the future of the Paris Agreement, and why every fraction of a degree of warming still matters. Alongside student activist Averie Gannon, the discussion moves beyond headlines to offer a more grounded, nuanced understanding of climate change—what the data says, where progress is being made, and where major challenges remain. If you enjoy this episode, you can find more from Green Frequency, featuring scientists, advocates, and frontline perspectives, on all major podcast platforms.

Elephant seals are helping map the Southern Ocean. This week on Oceanography, we’re sharing a special crossover episode from South Pole, another Pine Forest Media series focused on Antarctic science and research. In this episode, Dr. Clive McMahon explains how southern elephant seals are being equipped with ocean sensors to collect real-time data in one of the most remote and extreme environments on Earth. These deep-diving animals gather information on temperature, salinity, depth, and ocean productivity; especially during the Antarctic winter, when human access is nearly impossible. The conversation explores elephant seal behavior, population decline, Antarctic bottom water, and how animal-borne data is advancing oceanography, climate science, and weather forecasting. A fascinating look at how marine life is contributing directly to scientific discovery.

Solar geoengineering is a justice question. As sunlight reflection methods move from theory toward real-world research, who gets to decide what happens next? This episode explores the justice and governance questions surrounding solar geoengineering, also called solar radiation modification or SRM. Hassaan Sipra of the Alliance for Just Deliberation on Solar Geoengineering explains why the risks of climate intervention cannot be separated from existing inequalities in climate change, especially for climate-vulnerable communities in the Global South. The conversation covers environmental justice, public participation, free, prior and informed consent, governance gaps, research transparency, and why climate intervention must never replace emissions cuts, adaptation, climate finance, or loss and damage. A grounded, accessible finale to Oceanography’s marine climate intervention arc.

Shipping pollution changed clouds. What can scientists learn? What happens when cleaner shipping fuel suddenly changes the atmosphere above the ocean? In this episode of Oceanography, meteorologist Dr. Michael Diamond explains how shipping pollution, cloud formation, and climate are connected, and how a major fuel regulation and disrupted global shipping routes created a rare natural experiment for scientists. The conversation explores aerosols, sulfur pollution, cloud brightening, and what these real-world changes can teach us about marine climate intervention, including marine cloud brightening and solar geoengineering. If you want to understand how human activity is already shaping clouds, warming, and climate policy, this episode offers a grounded, fascinating look at one of the most complex questions in climate science.

Could reflecting sunlight help cool the Earth? Stratospheric aerosol injection, or SAI, is a proposed climate intervention that aims to reduce global temperatures by reflecting a small portion of incoming sunlight. Inspired by volcanic eruptions, this approach is being studied through climate and ecosystem models to better understand its potential effects. This episode explores how SAI could influence sea surface temperature, net primary production, ocean chemistry, and marine food webs. It also looks at how scientists use models to evaluate different deployment scenarios, including long-term use and phase-out strategies. Along the way, the conversation considers uncertainty, regional variability, and the role SAI might play within a broader portfolio of climate responses.
