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. But what exactly would cause the AMOC to collapse? What is the AMOC?
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. Research with climate models in recent years shows that when carbon dioxide emissions stop, the rise in atmospheric temperatures will likely also stop.
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.
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. 29, citing the Vienna Convention on the Law of Treaties, article 31).
are used all over the world, based on calculations that quantify the effects of physical mechanisms and the way different parts of the atmosphere are connected to each other. 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.
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. Removing carbon from the atmosphere will take a global effort towards significant innovation and rapid implementation. –Laurel Hunt, JD 2023.
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.
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.
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.
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
International agencies coordinate release of annual climate data to highlight the past years exceptionaland dangerousclimate conditions. By Bob Berwyn Nearly all major global climate datasets agree that, in 2024, human-caused global warming for the first time pushed Earths average surface temperature to more than 1.5
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.
As part of his physics degree at the University of Sheffield, Ashworth did a year abroad at Monash University in Melbourne, Australia, during which he took courses in climate dynamics of the atmosphere and oceans alongside pure physics. This uses various indicators, such as whether the companies have set net-zero targets.
There was little discussion, either in the written statements or at the oral hearing, of so-called “marine geoengineering” activities that seek to use the ocean to combat climate change. The hope is that the carbon will end up in the deep ocean, where it will remain stored for long periods, but that has not yet been proven.
This has resulted in a decline in fisheries health, more soil erosion and greenhouse gas emissions, as soil carbon, escapes into the atmosphere where mangroves are cut down or killed. Managing the oceans sustainably is a global issue, and as the world’s largest archipelago nation, Indonesia can play a leading role,” said Pengestu.
Student in the Department of Atmospheric Science at Colorado State University Most people remember the water cycle they learned in school: water evaporates from lakes, rivers, and the ocean, air carrying this moisture rises, cools, condenses, and forms clouds, and these clouds precipitate water back down to the surface.
The greenhouse effect is a popular name for the earth’s warming effect which occurs naturally when gasses in the atmosphere trap heat from the sun and prevent it from escaping back into space. The changes to the world's oceans include warming, more frequent marine heatwaves, ocean acidification, and reduced oxygen levels.
Being the predicted outcome of burning fossil fuels, our best and only plan to limit warming is to reduce CO 2 emissions from human activities to ‘net zero’ – where the amount of CO 2 we emit into the atmosphere is equal to the amount we remove from it. C limit of the 2015 ParisAgreement, this needs to happen as soon as possible.
In fact, the impact assessment supporting the Commission’s proposed 2040 target suggests that the EU may need to remove up to 400 million tons of carbon dioxide (CO2) from the atmosphere annually by 2040, and significantly more to achieve net-negative emissions after 2050.
degree C of warming by 2100 as opposed to the ParisAgreement aspiration of 1.5 Actions of the past, including nearly all climate agreements, put pressure on consumers to solve the climate crisis. The climate crisis cannot be solved unless we halt the transfer of carbon from its terrestrial tomb to the atmosphere.
CO 2 levels in the atmosphere hit an all-time high in early May. We are seeing the consequences in bushfires, acidifying oceans and locust invasions – which could push millions of people in East Africa into hunger. Think of the atmosphere as a bathtub, and emissions as the water that flows from the tap.
Acidification : Reducing the pH rating of a substance making it more acidic in nature, for example, increased carbon emissions lead to the oceans absorbing more of it, increasing acidification and damaging ecology such as coral bleaching. Air emissions : Any gas emitted into the atmosphere from industrial or commercial activity.
The latest data from the National Oceanic and Atmospheric Administration ( NOAA ) and the EU’s Copernicus climate service show that the 2024 January-August period is the hottest ever by far, putting this year well on track to be the warmest ever on record. of the ParisAgreement ). see Articles 4.2 Article 2.1(c)
The unrelenting heat has caused a dizzying number of air and ocean temperature records to be broken in recent weeks. As the climate continues to change due to human activities, oceans have absorbed over 90% of the excess heat. Ocean temperatures off the coast of Florida have reached as high as 97°F in recent days.
A magistrate judge in the federal district court for the District of Oregon granted motions by three trade groups to withdraw from the lawsuit seeking to hold the United States liable for its actions and inaction leading to the accumulation of greenhouse gases in the atmosphere. at its theme park in Jackson Township in Ocean County.
First, underwater – in the sediments on the bottom of swamps, lakes, and the ocean. OK, on to methane in the environment: The headline here – whether you’re talking about atmospheric concentrations, climate impacts, or emissions – is that there is a lot less methane than CO 2 , but it’s a more potent climate heater and it’s increasing faster.
will achieve a 29-42% reduction in GHGs in 2030—a meaningful departure from previous years’ expectations for the US emissions trajectory, but not enough for the US to meet its pledge under the ParisAgreement to reduce emissions by 50-52% below 2005 levels by 2030.” This is a visceral moment from Phoenix to the Florida Keys.
To the extent those sectors continue emitting carbon dioxide and other greenhouse gases, those gases will need to be captured prior to release into the atmosphere. to 2 o C target set in the ParisAgreement. Another option is to store the carbon dioxide in a way that prevents its release (or re-release) into the atmosphere.
International agreements, such as the ParisAgreement, and domestic legislation in the U.S. The IPCC has said that, in addition to reducing emissions, it will likely also be necessary to draw greenhouse gases out of the atmosphere to mitigate climate change. and elsewhere, have also been important in driving change.
If we rely only on the current climate commitments of the ParisAgreement, temperatures can be expected to rise to 3.2°C It gives us the food we eat, the water we drink, the materials with which we build our homes, and the mechanisms that regulate our weather patterns, our ocean currents, and much more. C this century.
According to the National Oceanic and Atmospheric Administration (NOAA) and the National Aeronautics and Space Administration (NASA), 2021 followed the distressing trend of excessive heat, as the sixth hottest year on record (a tie with 2018). degrees Celsius, in line with the ParisAgreement. Photo is author’s own.
That report, in the technical language of probabilities and scenarios, underscored the urgency of the moment and the need not only to reduce the release of heat-trapping gases into the atmosphere and limit global warming to 1.5 In the Parisagreement rich countries said they would contribute $100 billion annually.
It stressed the need to reduce the release of heat-trapping gases into the atmosphere, and to limit global warming to 1.5 The report also said it is necessary to enable communities to live with the challenges already confronting them such as extreme weather, acidifying oceans, and rising seas. degrees Celsius.
While the pursuit of accountability should consider their role in creating and spreading disinformation and their deception around climate science and research, their contributions of heat-trapping gases to the atmosphere are an important place to start. When visualizing data, clarifying the units used is critical.
Department of State to produce correspondence of two officials related to climate change, the December 2016 ParisAgreement, the “legal form” of the ParisAgreement’s provisions, the Kyoto Protocol, and the United Nations Framework Convention on Climate Change. National Oceanic and Atmospheric Administration , No.
Cop stands for conference of the parties under the UNFCCC, and the annual meetings have swung between fractious and soporific, interspersed with moments of high drama and the occasional triumph ( the Parisagreement in 2015 ) and disaster (Copenhagen in 2009). Why do we need a Cop – don’t we already have the Parisagreement?
A non-profit organization filed a Freedom of Information Act (FOIA) lawsuit in the federal district court for the District of Columbia seeking to compel the National Oceanic and Atmospheric Administration (NOAA) to respond to a request for documents related to the removal of retired U.S. Democracy Forward Foundation v. filed Sept.
degrees Fahrenheit) limits of the 2015 ParisAgreement. As the National Oceanic and Atmospheric Administration says on its Climate.gov website: “The United States bears a greater share of the responsibility for current conditions—on both a national and per-person level.” degrees Celsius (2.7-degrees
However, only 42 jurisdictions have acknowledged the importance of blue carbon as a climate mitigation and adaptation strategy in the Nationally Determined Contributions (NDCs) submitted under the ParisAgreement. Relevant phrases from NDCs, including these terms, were extracted and analyzed.
This latest report looks at mitigation — or what the world can do to stop pumping greenhouse gases into the atmosphere. Despite that scrap, the takeaway remains constant — there is no hope of stopping global warming at the ParisAgreement limits of 1.5 Here are five key messages from the final report. Halting at 1.5
