As we prepare to participate in the 10 th Our Ocean Conference in Busan, Republic of Korea, from April 28-30, I like to think about this beautiful poem in a different way. Just like in the poem, the ocean remains largely undiscovered, unknown. Warmer ocean waters impact marine ecosystems, including coral reefs and fisheries.
Just by looking at the name, you can see that a GCM is a model that simulates the circulation of Earths different physical systems like the atmosphere and ocean. The Earths atmosphere and oceans create circulations in order to mix temperature differences between regions; GCMs, or climate models, simulate these circulations quite well.
Other new studies At few other articles on this topic have also appeared recently: Allen and Merchant (2025) give a “new interpretation of the drivers of Earth’s energy budget changes and their links to ocean warming” Terhaar et al. 044002, 2025. Foster, "Global Warming has Accelerated Significantly", 2025.
There is no real ambiguity in the observed trends, nor in the comparison (though extent is a little trickier than area to compare to), and so these discrepancies were very likely due to model failures – insufficient resolution to capture the polar sea ice dynamics, too simple sea ice physics, biases in the Arctic ocean simulations etc.
On November 8, Pennsylvania Sea Grant recently announced three Pennsylvania early-career professionals-- Nathaniel Edelheit-Rice , Sahara Rios-Bonilla , and Chelsea Russ -- have been selected into the 2025 class of the Sea Grant John A. Knauss Marine Policy Fellowship program. candidates and 3 J.D. candidates.
The paper results from a major computational effort, based on running a state-of-the-art climate model (the CESM model with horizontal resolution 1° for the ocean/sea ice and 2° for the atmosphere/land component) for 4,400 model years. Figure adapted from Caesar et al., Nature 2018.
There is growing interest in exploring ways to counteract global warming by intervening in the atmosphere and the oceans, but planned trials are highly controversial
Ocean Conservancy recognized this from the very beginning when we published our ground-breaking report Stemming the Tid e. We knew the problem of ocean plastics required collective action. That is why Ocean Conservancy was thrilled to join the U.S. Thanks for signing up for Ocean Conservancy emails.

Background information: The Minister of Environment and Climate Change must decide whether the federal government will re-designate Highway 413 for a federal impact assessment by January 19, 2025 and the Minister of Fisheries, Oceans and the Canadian Coast Guard must issue a habitat protection order for Redside Dace by January 25, 2025.
As we mark Water Week 2025, preparing for extremes is critical for modernizing our water management. At the state scale, the snowpack is approximately the historical average, but there will be more water in the north and less in the south than average. In past years, supercharged snowmelt has led to flooding and dam safety concerns.
A study warns that the Atlantic meridional overturning circulation is close to a tipping point that would severely disrupt the climate – but other researchers say the timing is impossible to predict
Predictions for an above-average number of storms, communities that are still recovering and cuts to the National Weather Service have meteorologists and other experts worried about this hurricane season
Not in summer when the ocean is covered by a shallow surface mixed layer heated by the sun and highly dependent on weather conditions.) The argument has been made that the ‘cold blob’ might not be caused by an AMOC decline but by heat loss at the ocean surface. We argued in Caesar et al. The reanalysis data show the latter is the case.
At a rate of 400 feet per year, saltwater is migrating west from the ocean to once-secure inland groundwater reserves. Southeastern states are seeing saltwater intrusion the fastest, with the Maryland Geological Survey estimating an increase of 15 percent in state salinity by 2025. It’s a balance between the land and the sea.
This follows a decade of record-breaking temperatures, with the World Meteorological Organization concluding that the past ten years 2025-2024 are the ten warmest years on record. Seaweed naturally converts dissolved carbon dioxide in ocean water into organic carbon through photosynthesis. o C above pre-industrial levels.
This blog was written by Michele Conrad, advisor to Ocean Conservancy on achieving priority fish conservation and ecosystem goals on the West Coast. As a former state ocean policy manager, Michele represented the State of Washington on the Pacific Fishery Management Council for 15 years before starting her own consultancy.
And its not just that as much 40 percent of the oceans surface is now covered in plastic with billions of tons being added every day. And wouldnt Earth Day this year, April 22, 2025, be a great time to start? By Carol Hillestad for Brodhead Watershed Association The world has a plastic problem. Plastic is also in our bodies.
On March 4, 2025, the Supreme Court handed down an important ruling in City and County of San Francisco v. mCDR refers to ocean-based processes or techniques designed to remove carbon dioxide from the atmosphere and store it for long periods of time in the ocean. Environmental Protection Agency. How is mCDR affected?
It works for progress on methane pollution, clean electricity, clean transportation, forests, fisheries and oceans, healthy communities, fuels and feedstocks, agriculture, water, food, carbon markets and other critical environmental challenges. During the 2025-26 academic year, EDF staff will visit Dickinson for a multi-day residency.

With funding from the DEP Coastal Resource Management, Keep Pennsylvania Beautiful is continuing its collaboration with numerous individuals, organizations, and businesses to actively address and combat litter that makes its way into the waters of Presque Isle Bay, Lake Erie, and ultimately the ocean.
#TeamSeas has surpassed the goal of removing 30 million pounds of trash from our ocean. This global, groundbreaking partnership removed more than 34 million pounds, leaving our beaches and ocean cleaner for the people and animals who rely on them. But we did more than that. Altogether, the campaign amassed more than 1.3
Corals Colors by Rhylee Gangestad 25, an environmental studies major from Hagerstown, Maryland, follows a coral character and her ocean friends as they experience a bleaching event caused by climate change. The illustrations are bright and expressive and show the ocean both in distress and in recovery, depending on human action.

Fish like Shad, Herring, and Eel migrate from the ocean into the Susquehanna River to spawn. On the West Branch you might find large Elk impressions, while those on the Lower Susquehanna might spot three-pronged tracks of an Egret or a Heron in shallow water. Spring also stirs life beneath the water.

I thank the legislators and stakeholders who, through collaboration and compromise, have positioned Maine to pursue offshore wind in a manner that puts all Maine workers and businesses on a level playing field, invites investments in critical port infrastructure, and importantly, respects those who rely on the ocean for their livelihoods.
ITLOS published its advisory opinion in May 2024, and the IACtHR opinion is expected later in 2025. The request happened in parallel to similar advisory opinion processes before the International Tribunal for the Law of the Seas (ITLOS) and the Inter-American Court of Human Rights (IACtHR).
Ocean-going ships transport nearly three-quarters of the world’s cargo, but heavy-duty road vehicles contribute to the majority- 65% of emissions from freight. The Netherlands’ Green Deal serves as a successful example, with 30-40 cities committing to implementing ZEZ by 2025.
