Last month, 44 climate scientists from 15 countries wrote an open letter to the Nordic Council of Ministers highlighting the risk of a potential collapse of the Atlantic Meridional Overturning Circulation (AMOC), a critical ocean current system in the Atlantic Ocean. Picture Quebec City in Canada and London in the UK.
In the study, we found that political power dynamics shape international negotiations, that the ParisAgreement temperature goal doesn’t fully account for the dangers of sea level rise, and that climate justice requires fully considering diverse views and experiences of climate change.
Because of the way the climate and ocean systems respond to heat-trapping emissions, sea levels will continue to rise even after air temperatures stabilize. So, even in a future scenario where the world achieves the stabilization of air temperatures, the Earths oceans and cryosphere (frozen regions like Antarctica ) will continue to adjust.
That’s how long Ocean Conservancy has been advancing policies that secure a healthy ocean and a thriving planet.

Yet despite its critical role, the ocean is often sidelined in global climate discussions.
While nonbinding, the unanimous advisory opinion offers important support for small island nations facing climate impacts and raises the bar for other nations to reduce their global warming emissions to protect the world’s oceans. Brings together international climate agreements. Lays out polluting nations’ obligations.
By Bob Berwyn Fresh water from melting Antarctic ice is projected to weaken the worlds most powerful ocean current by 20 percent in the next quarter century, an international team of scientists concluded in a study published today in the journal Environmental Research Letters.
By Bob Berwyn A trio of reports released ahead of next month’s COP29 climate conference in Azerbaijan all show that the existing national policies to cut greenhouse gas emissions under the landmark 2015 ParisAgreement will heat the planet by close to 3 degrees Celsius by 2100, as warming has accelerated in the past few years.
That’s because the parties to the London Convention and London Protocol are meeting from October 28 to November 1 in London to discuss, among other things, governance of ocean alkalinity enhancement and ocean sinking of biomass (e.g. to 2 o C in line with the goals of the ParisAgreement. seaweed) for carbon storage.
Most participants agreed that greenhouse gas emissions must be reduced and urgent measures must be taken to meet the goals of the ParisAgreement. For instance, Germany contended that the ParisAgreement and the UNFCCC are the decisive treaties to determine the obligations of States in the context of climate change.
Representatives from civil society, non-governmental organizations and the private sector gathered alongside governmental representatives to influence decisions and advance contributions toward the goals of the ParisAgreement of 2015. I was joined by Ocean Conservancy colleagues working to advance ocean-climate action.
Its location between two oceans, as well as its latitude and topography significantly increase Mexico’s exposure to extreme hydro meteorological events.” Mexico’s climate commitment for 2030 under the ParisAgreement calls for cutting emissions 22%, cutting black carbon by half, and achieving net-zero deforestation.
The Tribunal acted both boldly and conservatively by interpreting UNCLOS as an independent source of international legally binding obligations to address climate change and ocean acidification. The Tribunal emphasized in this respect, “the global temperature goal of limiting temperature increase to 1.5°C
Some countries argued that including methods for ocean alkalinity enhancement and direct ocean carbon capture, two experimental marine CDR technologies, could prematurely legitimize these technologies before their environmental impacts are fully understood.

However, on the level of basic physical reasoning, it is of course a no-brainer that warming will cause land-ice to melt (and melt faster as it gets hotter) and ocean waters to expand, so sea-level rise is the inevitable result. That depends on our emissions and is shown in the following figure. Source: IPCC AR6, Figure SPM.8.
The basis of this relationship is the rough balance between the net uptake of carbon into deep pools (mainly the deep ocean) and the rate at which the oceans warm in response to an energy imbalance. This figure is from the AR6 SPM: The relationship between cumulative carbon emissions and temperature (SPM AR6).
Spearheaded by the Republic of Vanuatu, they want the court to clarify how existing International Law can strengthen governmental action on climate change, protect public health and the environment, and save the save the ParisAgreement.
As the Earth’s air and oceans warm, the ice sheet is starting to melt at an ever-faster rate. The Antarctic Ice Sheet has grounded ice, which is ice that sits on the solid Earth below it and ice shelves, which extend out from the grounded portion and float on the ocean surface. These are called marine basins.
goal of the ParisAgreement, but I do think that it will be possible for us to keep warming under 2C and avoid the most devastating effects of climate change. There are options from blue carbon in the ocean to soil carbon and more. I do not believe that we’ll prevent average global temperatures from exceeding the 1.5C
From COSIS to ITLOS The ocean and climate are inextricably linked. On one hand, numerous adverse effects of climate change manifest in the ocean, such as ocean acidification, temperature changes, and rising sea levels. On the other hand, the ocean plays an important role in combating climate change.
My research evolved over time, but initially focused on trying to understand how ice sheet collapse—specifically Antarctic ice sheet collapse—could impact climate change around the world through changes in the oceans, sea ice and atmosphere. How did we end up with global average temperature as a metric in the Parisagreement?

The Sabin Center today published model federal legislation to advance safe and responsible ocean carbon dioxide removal (CDR) research in U.S. Controlled field trials and other in-ocean research is critical to improve scientific and societal understanding of CDR techniques that could help the U.S. reach its climate goals.
It’s also urgent because the oceans act like a flywheel, making sure that cuts in emission of greenhouse gases will have a lagged effect on global warming. This fact is underscored by recent weather-related calamities , such as flooding in Central Europe and heatwaves over North America.
The planet has accumulated as much heat in the past 15 years as it did in the previous 45 years; the ocean has absorbed the majority of this excess heat. Scientists have consistently warned that the continued burning of fossil fuels is heating the planet, including the ocean.
In fact, at this critical moment for the climate and our ocean, there were literally more press credentials distributed than at any previous COP conference. Climate change is here and is bringing with it impacts like ocean acidification, sea level rise and dwindling sea ice. Thanks for signing up for Ocean Conservancy emails.
Wildfire in Canada , smoke in NYC , heat domes in Texas , massive heat in the Atlantic ocean are just some of this month’s news. At the top of that list is JPMorgan Chase, the largest funder of fossil fuels cumulatively since the ParisAgreement on climate change was signed in 2016, according to the report.
The physics-based models describe how energy flows through the atmosphere and ocean, as well as how the forces from different air masses push against each other. Furthermore, the volume of the oceans increases from the melting of land ice. The global sea level acts like the mercury in a thermometer because warmer water expands.
Creator: George Stoyle The oceans absorb large quantities of the carbon dioxide emitted by human activities. This “sink” function is so significant that, until 1957, one objection to a causal link between anthropogenic emissions and global warming was that the oceans would absorb most of the excess CO2, thus breaking this link.
The Sabin Center wrapped up Climate Week NYC last Friday with an event exploring the opportunities and challenges posed by ocean-based carbon dioxide removal (CDR). As evidenced by the 150-plus people in attendance, ocean CDR is attracting growing attention as a possible climate change mitigation option. ground rock) into the ocean?
Cross–border CCS operations have specific and detailed rules under the emissions inventories and NDCs required for parties to the ParisAgreement. Cross–border CCS operations have specific and detailed rules under the emissions inventories and NDCs required for parties to the ParisAgreement.
Consequently, the response to this advisory opinion request should consider the climate change regime set by the United Nations Framework Convention on Climate Change (UNFCCC) and the ParisAgreement (ParisAgreement) concerning the ocean. The question is divided into two parts.
Whereas the science—synthesized in recent assessments and special reports by the Intergovernmental Panel on Climate Change (‘IPCC’)—emphasizes the deep interlinkages between issues of climate change, marine and terrestrial biodiversity loss, and ocean degradation, the international legal response is fragmented and uncoordinated.
By Bernice Lee Following the ParisAgreement, corporate enthusiasm for climate action surged, with net-zero commitments and the energy transition taking a central role in both government and business agendas. Resilience offers a forward-looking approach to corporate climate action and energy transition strategy.
Thanks for signing up for Ocean Conservancy emails. Their work paved the way for international agreements to tackle the crisis like the Kyoto Protocol and ParisAgreement. What does this mean for the ocean? The ocean is both a victim of climate impacts and a vital part of climate solutions. As many as 3.6
My colleague Courtney Carmichael and I will represent Ocean Conservancy during these negotiating proceedings informing and advising negotiators and interested parties on policy for adoption in this agreement. What are Ocean Conservancy’s priorities for this agreement?

States’ obligation to prevent, reduce, and control the pollution of the marine environment related to greenhouse gas (GHG) emissions), where ITLOS developed with greater detail States’ obligations to reduce GHG emissions under UNCLOS, and examined the relationship between UNCLOS and the ParisAgreement.
While countries generally do not explicitly reference CDR in their Nationally Determined Contributions (NDCs) submitted to the ParisAgreement, many include the CDR approaches of increasing soil and forest carbon. The ParisAgreement did not reference or define CDR, nor did it define the term “removals.” The Article 6.4
Best estimates to date suggest that the global surface temperature would stabilize within a few decades, but the new paper in the journal Frontiers in Science examines the uncertainties around that conclusion, including how the planet’s key carbon dioxide-absorbing systems, like forests and oceans, will respond.
Thus, ITLOS clarified UNCLOS as a legal basis for obligations to address climate change and its adverse effects, alongside the United Nations climate treaties, i.e. the United Nations Framework Convention on Climate Change ( UNFCCC ) and the ParisAgreement. This is most pronounced in the references to the ParisAgreement.
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. Moreover, it is important for regional or national governments to prioritize meeting the targets set by the ParisAgreement, supporting cities in their efforts.
The G7 calls for ensuring that private investments and financial flows are consistent with a healthy climate , as committed to in the ParisAgreement. This suggests these high-consumption countries are fine with the fact that, right now, one dump truck worth of plastic leaks into the world’s oceans every minute.
