Our latest research published today in Environmental Research Letters adds a critical piece to this legal and scientific puzzle by quantifying how emissions from the worlds largest fossil fuel and cement producers have directly contributed to sealevel rise, both historically and in the centuries to come.
In a new study released today, UCS attributes substantial temperature and sealevel rise to emissions traced to the largest fossil fuel producers and cement manufacturers. m (10-21 inches) of sealevel rise by the year 2300. And critically, we demonstrate how these emissions will cause harm for centuries to come.
My top 3 impressions up-front: The sealevel projections for the year 2100 have been adjusted upwards again. The IPCC gives more consideration to the large long-term sea-level rise beyond the year 2100. And here is the key sea-level graphic from the Summary for Policy Makers: Source: IPCC AR6, Figure SPM.8.
Three new papers in the last couple of weeks have each made separate claims about whether sealevel rise from the loss of ice in West Antarctica is more or less than you might have thought last month and with more or less certainty. Two elephant seals in the Southern Oceans arguing about marine ice cliff instability.
Sealevel rise presents numerous climate justice issues. New research that I led as part of my PhD dissertation, which was just published in Earth’s Future , digs deep into the topic of sealevel rise and climate justice. Climate justice research can help inform these conversations.
It shows the atmospheric concentrations of carbon dioxide (CO 2 ) and tells a story about the carbon cycle, involving Earth’s crust, the atmosphere, land surface, the biosphere, and the oceans. In a nutshell, they are responsible for climate change, mainly due to an increased greenhouse effect.
There is no doubt that we have changed Earth’s climate through our activities on a broad range of aspects that includes consequences for the atmosphere, the oceans, snow, ice, Earth’s fauna and ecosystems. The cause of our changing climate is the increase in atmospheric greenhouse gas concentrations that we have released into the air.
Sealevel rise is a big deal Use, abuse and misuse of the CMIP6 ensemble The radiative forcing bar chart has gone full circle Droughts and floods are complicated Don’t mention the hiatus. SeaLevel Rise: The previous IPCC reports, notably AR4 and AR5 (to a lesser extent) , have had a hard time dealing with SLR.
A friend asked me if a discussion paper published on Statistics Norway’s website, ‘ To what extent are temperature levels changing due to greenhouse gas emissions? ’, was purposely timed for the next climate summit ( COP28 ). The global sealevel acts like the mercury in a thermometer because warmer water expands.
Here are a number of the lowlights: It is unequivocal that human influence has warmed the atmosphere, ocean and land. Widespread and rapid changes in the atmosphere, ocean, cryosphere and biosphere have occurred. Global warming of 1.5°C
Think about what is involved – biological proxies from extinct species, plate tectonic movement, disappearance in subduction zones of vast amounts of ocean sediment, interpolating sparse data in space and time, degradation of samples over such vast amounts of time. All of which adds to the uncertainty. van der Meer, C.R. Scotese, B.J.
I was joined by Ocean Conservancy colleagues working to advance ocean-climate action. C, we stand to lose ocean and coastal ecosystems we depend on to sealevel rise, warming temperatures, ocean acidification and other climate impacts. degrees Celsius. If we warm beyond 1.5°C, If we warm beyond 1.5°C,
Working Group 3: Mitigation of Climate Change Evaluates pathways for reducing greenhouse gas emissions, sustainable development strategies, and the role of finance, technology, and policy in achieving net-zero emissions. Marine CDR lacks long-term observational data and has potential ecological risks.

By Anders Lorenzen On the eve of the COP28 UN climate summit, The World Meteorological Organization (WMO), a United Nations (UN) body, has warned that the atmospheric concentration of greenhouse gases (GHG) is forecast to continue the trend that resulted in record-high CO2 measurements last year.
As deeply troubling reports continue to come in about ocean waters hitting historic hot temperatures, sectors like global shipping are trying to understand the consequences of a warmer ocean and what can be done to stop the heating. Warmer water also expands and raises sealevels as well as holds less oxygen.
Our oceans are acidifying. A new report has warned that the level of acidity in the world’s oceans is higher now than it has been for the past 26,000 years. The heat trapped by human-induced greenhouse gases will warm the planet for many generations to come.” ” How the oceans absorb carbon and store the heat.
With proposed federal regulation of greenhouse gas emissions by the Securities and Exchange Commission requiring GHG disclosure and new state statutes, including a new Maryland law that requires not only disclosure, but also a mandated reduction in GHG emissions, a greater appreciation of the subject of GHG appears in order.
Total loss of the Greenland ice sheet, for example, would raise sealevels globally by more than 20 feet. Multiplying proposals Last month the ‘Ocean Visions’ coalition of research institutions released an Arctic Sea Ice Road Map. Will there be adequate vessels suitable to operate in polar oceans?
The world is gathering soon in Glasgow to debate how to eliminate greenhouse gas emissions over the coming decades. First, after carbon dioxide emissions cease, atmospheric carbon dioxide levels begin to decrease, as they are absorbed by natural processes and sinks in the oceans and on land. degrees Celsius.
Westlaw searches for “global warming” and “greenhouse effect” pick up only a handful of citations before 1985. The other article about nuclear power also observed in passing that “coal combustion may disrupt global weather patterns by increasing the amount of carbon dioxide in the atmosphere, creating a ‘greenhouse effect.’”.
For example, researchers at the Union of Concerned Scientists have directly linked fossil fuel producers’ Scope 1 and Scope 3 emissions to increases in ocean acidification , global temperature, sealevel rise and North American wildfires. Celsius above preindustrial levels.
The Advisory Opinion addresses several key questions regarding application of the United Nations Convention on the Law of the Sea (UNCLOS) in the context of climate change, including the interaction between UNCLOS and the global climate change regime, and the specific obligations of States to reduce climate-damaging greenhouse gas (GHG) emissions.
The ocean retains heat for much longer than land does. But that doesn’t mean the planet returns to its preindustrial climate or that we avoid disruptive effects such as sea-level rise. Over the years, scientists added oceans , land, ice sheets, chemistry and biology. Oceans in the future. By Richard B. Ricky) Rood.
In the run-up to the Copenhagen climate negotiations in 2009, President Mohamed Nasheed held a cabinet meeting in scuba gear 20 feet underwater to show what awaited the low-lying island nation of the Maldives if serious action were not taken to reduce greenhouse gases. I have been in the capital, Male, this week helping lead a U.S.
They are indeed valuable indicators for the global or regional mean temperature, greenhouse gas concentrations, both ice volume and area, ocean heat, acidification, and the global sealevel.
Some of those predicted changes are already happening such as continued sealevel rise which is now irreversible over a time span of hundreds to thousands of years. And by the end of this century, extreme sea-level events which previously occurred every 100 years could happen every year. What’s to come.
But plastics present a much broader threat to our ocean, climate and marginalized coastal communities. More plastic means more pollution—for the climate, coastal communities and our ocean. Plastic pollution is a social justice issue, a climate issue and an ocean issue. Want to learn more about Ocean Justice?
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, sealevel rise and dwindling sea ice. Time is running out.
As the risks of sea-level rise, stronger tropical storms and seawater intrusion grow due to climate change , Indonesia is ramping up efforts to protect mangrove ecosystems across the archipelago as part of both its COVID-19 recovery efforts and climate change commitments.

Scientific reports on climate issues, as well as reports on the state of the ocean, its ecosystems, and the relevance of the ocean for climate change, play a central role in the opinion. 52-54) and acknowledged the critical role the ocean plays in regulating the climate system (para. 157 as used in para. 52, 54, 60 and 68).
Writing as part of Frontiers’ guest editorials series, the study’s lead author – Prof Martin Siegert, deputy vice chancellor of the University of Exeter (Cornwall) – discusses how without there being a rapid shift to net-zero greenhouse gas emissions by 2050, the Antarctic environment will experience ever more drastic changes.
The consequences of climate change aren’t reserved for the oceans and atmosphere: Diseases have secured a larger presence in recent years thanks to global warming. We need to aggressively reduce greenhouse gas emissions.”. By Jenessa Duncombe. Global warming has, in certain instances, amped up some of the world’s most deadly diseases.
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 Paris Agreement (Paris Agreement) concerning the ocean. However, ITLOS is not responsible for implementing the UNFCCC or the Paris Agreement.
The Governor approved a notable slate of climate legislation with a package that includes more stringent greenhouse gas (GHG) emission targets and measures designed to reduce the state’s reliance on fossil fuels. Climate Change Mitigation. A Few Notable Vetoes.
Climate change is a problem which has a known solution: We must dramatically reduce our greenhouse gas emissions and prepare now for intense climate impacts. Thanks for signing up for Ocean Conservancy emails. As the CEO of Ocean Conservancy, I naturally look to our ocean. You can take action with Ocean Conservancy today.
Understanding Climate Change & Greenhouse Gas Emissions. 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. Greenhouse Gas Emissions are Increasing.
On the other hand, the chapter’s assessment of alternative plant proteins is more measured, noting their potential to reduce greenhouse gas emissions but also identifying the clear downsides in terms of increased needs for infrastructure and energy. Sealevel rise is also important in the region, causing saltwater intrusion and salinization.
Here are a number of the lowlights: It is unequivocal that human influence has warmed the atmosphere, ocean and land. Widespread and rapid changes in the atmosphere, ocean, cryosphere and biosphere have occurred. Global warming of 1.5°C
Rising sealevels and increased intensity of storm surges are playing a considerable role in the degradation of coastal regions in the Pacific Islands. Illustrating the variation in sealevels from 1993 – 2018. Ideally, the best way to save these islands is to reduce our greenhouse gas emissions. should be.
It is time the United States, as historically the largest emitter of greenhouse gases, investigates ways it can support those displaced by environmental destruction caused by climate change. Our own actions have ultimately caused the demise and destruction of homelands, from islands in the Pacific Ocean to Florida.
Accelerated action through deep cuts in greenhouse gas (GHG) emissions is needed to avoid the mounting loss of life, biodiversity and infrastructure. A path for adaptation. The report outline the options for adapting to a changing climate and provides new insights into nature’s potential?
Clean ocean energy solutions are critical to reducing emissions and averting the climate crisis. Climate change is the single greatest threat our ocean faces. It puts the wildlife and communities that depend on the ocean at risk through impacts like ocean acidification, sealevel rise and temperature changes.
