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. Picture Quebec City in Canada and London in the UK.
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.
By Bob Berwyn A new set of detailed clues gleaned from ancient fossil reefs on the Seychelle Islands shows an increasing likelihood that human-caused warming will raise the global average sealevel at least 3 feet by 2100, at the high end of the projections by the Intergovernmental Panel on Climate Change.
An analysis of peat layers at the bottom of the North Sea shows how fast sealevel rose during the end of the last ice age, when Earth was warming at a similar rate as today.
( ) According to scholars, in the poem The Sea and the Butterfly , beloved Korean poet Kim Kirim uses the sea to illustrate the harsh reality of his times and the butterfly to express the fragility of life in the face of adversity. Just like in the poem, the ocean remains largely undiscovered, unknown.
Melting land ice contributes to a higher global sealevel. The overall Arctic ice loss has contributed far more to global sea-level rise than any other region on Earth. There are several changes in the Arctic that will affect both the globe as well as the mid-latitudes.
The rapid meltdown of polar ice could shut down a key ocean current by 2050, triggering catastrophic surges of sealevel rise along the U.S. East Coast and dangerous climate shifts in northwestern Europe.
Atoll islands with healthy ecosystems are less likely to disappear as oceans rise, research shows. Now, scientists are using nature-based solutions — like restoring coral reefs and native forests — to improve the odds that more vulnerable islands will withstand higher seas. Read more on E360 →
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.
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.
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.
Moreover, changes in the Arctic have a huge impact on weather patterns north of the equator, including polar vortex disturbances, changes to ocean currents, and extreme heat domes. Shrinking Greenland ice sheet and mountain glaciers also contribute to accelerating sealevel rise. in Arc2024 ).
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. Lower-emission scenarios (SSP1-2.6) Meanwhile, an intermediate scenario (SSP2-4.5)
Australia has offered a lifeline to the people of Tuvalu, whose island is threatened by rising sealevels. But the deal comes with strings attached – and there will be millions more climate migrants in need of refuge by 2050
Instead, a significant portion of the water taken from underground flows off the land through rivers and on to the oceans. The researchers were surprised to find that the loss of water on the continents has grown so dramatically that it has become one of the largest causes of global sealevel rise. Reager, Fan Zhang (2025).
The persistent loss of water from land to oceans has dried out huge portions of every continent and may be irreversible, scientists describing the new research said this week.
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.

Two, in particular, warrant special attention: (1) the issue of knowledge , and (2) the so-called drop in the ocean argument. 51) Or, to use the popular image of the “drop in the ocean,” the drop should not be assessed in relation to the entire ocean, but in relation to other drops. A similar case is pending in Switzerland.
This is probably due to warmer ocean temperatures. “We We know what’s causing the warming of sea surface temperature: the emission of greenhouse gases. This dynamic occurs because of how the ocean temperatures that fuel the storms interact with other factors, such as wind shear, to decide their ultimate intensity, he says.
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.
Our own actions have ultimately caused the demise and destruction of homelands, from islands in the Pacific Ocean to Florida. In 2014, a family from Tuvalu sought refugee status in New Zealand because rising sealevels threatened their home. Recent catastrophic events illustrate this urgency.
That rose to an average of 37 days a year by 2020 , according to tide gauge monitors by the National Oceanic and Atmospheric Administration. The cobblestones along the town’s waterfront once were flooded a handful of times a year.
One such agency is the National Oceanic and Atmospheric Administration (NOAA), which provides the scientific bedrock of data needed to protect our health, homes, and livelihoods from climate change and other environmental threats. From coastal erosion to pollution, NOS’s science helps states and communities manage these resources sustainably.
And that’s a really important question to answer, since it has a total of 24 feet of sea-level rise still locked up in its icy mass. DelViscio: Because ultimately, you know, if the whole of the ice sheet melted, that’s 24 feet of sea-level rise. Feltman: Yeah.
Earlier today, my colleague Shaina Sadai released a peer-reviewed study that links emissions traced to the Carbon Majors to present-day and future sealevel rise. Previous UCS studies have already linked their emissions to increases in global average temperature , ocean acidification , and area burned by wildfires.
As some of the worlds highest emitters of the carbon emissions that cause climate change, fossil fuel companies face heightened levels of these risks compared to other industries.
Project 2025, the far-rights playbook for systemically reshaping the federal government, specifically calls out the National Oceanic and Atmospheric Administration (NOAA) to be dismantled, downsized, and eliminated. NOAA watches the oceans and coasts for you Do you like seafood? Are you taking a commercial flight today?
Overfishing, the unsustainable practice of taking too many fish out of the ocean so that there are too few left to replace themselves, results in the total collapse of fisheries, and economic devastation for surrounding fishing communities. Here are ten lesser-known responsibilities of NOAA scientists.
1) People are feeling the impacts of climate change and footing the bill The impending arrival of Danger Season is a stark reminder that climate change impacts are already devastating communities worldwide, intensifying many kinds of extreme weather events, driving sealevel rise, and harming human health.

The GreenDrill site sat on the frozen edge of the Northeast Greenland Ice Stream, or NEGIS, a massive, moving tongue of ice that drains 12 to 16 percent of the ice sheet into the ocean. If the entire Greenland ice sheet melted, global sealevels would rise by about 24 feet. Upended and laid atop the contiguous U.S.,
Accelerating sealevel rise, ocean acidification and loss of major ice sheets also continue apace, with profound consequences for the planet. Extreme climate-related disastersincluding heatwaves, storms, droughts, wildfires and floodingare worsening, taking a fearsome toll on people, the economy and ecosystems.
In Jakarta, sinking due to groundwater withdrawals and urban growth, lies Lake Pluit, which is below sealevel. The EPA held the city broadly responsible for the oceans water quality standards while San Francisco could use the ocean as a dumping ground, it would violate the permit should water quality worsen.
Water circulation in the Atlantic Ocean has slowed to its weakest recorded level, and global warming is the likely cause thats according to a new study in the journal Nature. It could also raise sealevels along the United States East Coast. Scientists say that global warming affects ocean circulation in various ways.

and the Danish territory have the opportunity to capture and monetize the torrent of clean fresh water pouring off Greenland and into the North Atlantic and Arctic oceans. If all of Greenlands ice melted, sealevel would rise about 24 feet. for instance, crosses 1,800 miles of ocean and seaway and takes 15 to 20 days.
New research finds that Greenlands ice sheet is cracking more rapidly than ever as it remains on track to increase sealevels by one meter by this centurys end. By 2100, the ice sheets melting is on track to increase sealevels by about one meter, and 10 meters by 2300.
Every week, hundreds of bales of used clothes are delivered to the Kantamanto secondhand market in Accra, and every day, around 100 tons of unsold garments leave the market as waste, with much of that going to lagoons, wetlands, and the ocean, according to a local waste official. Push on Seabed Mining End Global Consensus on Oceans?
The planned cuts to the National Oceanic and Atmospheric Administration (NOAA), according to news reports , are not the equivalent of trimming but of sawing a whole tree down to the ground. This NOAA graph shows observed sealevel from 2000-2018, with future sealevel through 2100 for six future pathways.
trillion in flood mitigation value alone , a value that has grown more critical with sealevel rise and increased frequency and intensity of storms and wildfires. According to the National Oceanic and Atmospheric Administration (NOAA), commercial and recreational fisheries provide 1.7 trillion and $2.9 million jobs.
