Sealevels are rising, and science shows they will continue to rise for generations due to heat-trapping emissions that have already been released. Understanding sealevel rise as a long-term, multi-generational problem is essential to comprehending the scale of climate change and the need for bold action now.
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.
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?
In an era when massive heat domes blanket large swaths of continents for days, wildfires burn through areas the size of small countries, and hurricanes regularly push the limits of what we once thought possible, sealevel rise can seem like extreme weather’s low-key cousin. Since 1993, sealevel has risen by an average rate of 3.1
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.
Guest commentary by Robert Hart, Kerry Emanuel , & Lance Bosart The National Weather Service (NWS) and its parent agency, the National Oceanic and Atmospheric Administration (NOAA), delivers remarkable value to the taxpayers. This efficiency can be demonstrated by its enormous return on investment.
Whats the point of a beach adventure if you cant even go into the ocean? In 2022, ninety of Texas beaches tested positive for unsafe levels of fecal bacteria (poop!), How does raw sewage end up in our oceans and rivers? miles into the Pacific Ocean near Ocean Beach. San Francisco City and County v.
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. The Keeling curve, highlighted with the release of important climate reports and climate summits.
If you live in a coastal zone and have looked at maps of future sealevel rise or have read about how climate change could be slowed with policy changes to reduce emissions, youve likely seen these scenarios in action. Four RCP scenarios describe different levels of radiative forcing in the atmosphere by 2100.
For the first time, the Arctic Report Card assessed that the Arctic is faltering as a reliable area for storing carbon away from the atmosphere ( Natalie et al., It was its first failing grade after thousands of years holding onto more carbon than released to the atmosphere. in Arc2024 ). Methane releases were sustained as well.
An expert on sealevel dynamics and climate justice within the UN negotiations, Dr. Sadai is working to ensure that her scientific studies get in the hands of decisionmakers who are shaping our world today. UCS’s new Hitz Family Climate fellow, Dr. Shaina Sadai , is stepping into this emerging area of work.
Another clue indicating a shortcoming is if you look at the atmospheric CO 2 -concentrations over time to see how much impact the IPCC reports have had on the real policy-makers in the world (Figure below). 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.
Here we start by taking the Greenland mass loss rate into the ocean, times the temperature difference between the meltwater and the water it replaces. For the part entering the ocean as ice, we must also consider that to melt ice requires energy. Greenland ice melt. or other estimates). Rahmstorf, S., Robinson, A., Feulner, M.E.
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. My emphasis.).
Despite promising adaptation strategies, sealevel rise is projected to drown tens of thousands of acres of farmland within the century. He makes his living on the Turnbridge Plantation in his hometown of Hardeeville, South Carolina, 30 minutes from the Atlantic Ocean. Storm events are getting steadily more intense.
by Jianjun Yin, University of Arizona Sealevels are rising, and that will bring profound flood risks to large parts of the Gulf and Atlantic coasts over the next three decades. A new report led by scientists at the National Oceanic and Atmospheric Administration warns that the U.S.
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.
A simple statement that masks just how complicated the issues are: mixing politics, economics, livelihoods, fisheries and endangered species in the ocean body that is the Gulf of Maine. He was on to something And the lobsterman was correct: we can blame carbon emissions for ocean acidification and warming in the Gulf of Maine.
For ocean advocates like me who have been tracking the $1.5 In coastal counties, which are home to about 40% of the United States’ population, critical water infrastructure is growing more vulnerable to climate change and faces a host of compounding hazards such as sealevel rise and flooding, heavy precipitation and extreme storm surges.
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.
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.
In particular, he said, “reliance upon coal, on the other hand, could aggravate the ‘greenhouse effect,’ whereby excess carbon dioxide (which accompanies coal burning) traps heat inside the earth’s atmosphere, thus possibly melting the icecaps and raising the level of the oceans.”
Some marine species also experience boundaries to movement, including ocean currents, thermoclines, and shipping lanes, but they are generally more able to track changes in sea temperatures. In the oceans, prolonged periods of unusually high sea surface temperatures are having a major impact.
The ocean retains heat for much longer than land does. If people everywhere stopped burning fossil fuels tomorrow, stored heat would still continue to warm the atmosphere. But that doesn’t mean the planet returns to its preindustrial climate or that we avoid disruptive effects such as sea-level rise. By Richard B.
Today the National Oceanic and Atmospheric Administration (NOAA) released its annual report on billion-dollar weather and climate-related disasters in the United States, which tells a grimly familiar story. Wherever you live in the United States, you were undoubtedly affected by these disasters, directly or indirectly.
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 sealevels. On the other hand, the ocean plays an important role in combating climate change.

Sealevels were quickly rising, and the rapid waters kept sediment from settling. However, when combined with climate change impacts like rising sealevels, the intensity of these threats becomes magnified.
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.

That 2013 headline resulted from the first effort to quantify emissions from the ‘carbon majors’ —fossil fuel companies and cement manufacturers whose businesses have contributed an outsized amount of heat-trapping gases to the atmosphere.
For 2022, the National Oceanic and Atmospheric Administration (NOAA) predicted a season with above normal activity on its August 4 updated forecast , calling for 14-20 named storms. .” After all, we hardly had storms or hurricanes in the news for the past 3 months.
Research produced by the Union of Concerned Scientists (UCS) has shown that rising temperatures, sealevel rise , and ocean acidification have all been made worse by fossil fuel companies’ activities and products.
We’ve heard so much about the effects of climate change on our ocean. Carbon pollution from fossil fuel use and land development have heated the atmosphere and ocean, leading to sealevel rise, stronger storms, fisheries’ moving poleward, and widespread loss of sea ice and glaciers.
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).
For example, consider how climate change is often described as an increase in parts per million of atmospheric CO 2 , inches of sealevel rise, square kilometers of melting arctic ice, increasingly severe and unpredictable weather patterns, and ocean acidification.
Atmosphere The gaseous envelope surrounding the Earth. The dry atmosphere consists almost entirely of nitrogen (78.1% The dry atmosphere consists almost entirely of nitrogen (78.1% In addition, the atmosphere contains water vapor, whose amount is highly variable but typically 1% volume mixing ratio.
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?
The production was made possible through funding from the National Oceanic and Atmospheric Administration (NOAA). Since 2012, Pennsylvania Sea Grant has invested over $5.7 The videos are available online via the programs website , and YouTube Channel. million in Great Lakes, coastal, and watershed research.
Part of this movement is an oscillation on a timescale of about a year – caused by short-term fluctuations such as changes in ocean currents and atmospheric pressure. This allowed GRACE to determine the shape of the Earth and monitor changes in sealevel, glaciers and groundwater.
Each IPCC report gives us more insights into how our ocean is changing, how those changes might impact the wildlife and communities that depend on it, and the options for ocean-based climate solutions.

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.
In addition, it stores vast quantities of freshwater that if released to the ocean would rise sealevel by tens of meters and interfere with saline-driven ocean currents that transfer heat around the planet. In the ocean, 19 marine heatwaves have been recorded between 2002 and 2018.
