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.
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
The threat of flooding and erosion is increasing throughout the United States as a warming atmosphere makes precipitation events more extreme and contributes to sealevel rise. local land use planning that implements sealevel rise adaptation strategies). In fact, the U.S.
A new map tool from the Union of Concerned Scientists shows you where and when critical pieces of coastal infrastructure such as public housing buildings, schools and power plants are at risk of repeated, disruptive flooding due to climate change-driven sealevel rise.

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.
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.
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.
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.
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.
By comparing these two data sets, scientists can determine the probability that human activities are responsible for observed changes in temperature, precipitation patterns, sealevel rise, and other climate change indicators. Climate source attribution studies can inform strategies to reduce carbon emissions.
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.
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.
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.
Despite promising adaptation strategies, sealevel rise is projected to drown tens of thousands of acres of farmland within the century. Atlantic sealevels are rising three to four times faster than the global ocean average. Saltwater intrusion on Chalmers’ rice paddies is forcing him to look for land elsewhere.
Meltwater from Greenland’s ice sheets have caused about a quarter of the rise in the world’s sealevels. It finds more evidence that severe weather events are linked to carbon in the atmosphere and that those weather events are becoming more extreme. Just as human behavior causes atmospheric warming, it can also prevent it.
But when there are really heavy rain events, like atmospheric rivers , these systems often overflow untreated wastewater (raw sewage) mixed with stormwater into surrounding waterways, streets, sidewalks, businesses and even homes.
By Bob Berwyn At the current level of human-caused global warming, extreme rainfall from atmospheric rivers, as well as an extensive network of previously undetected micro-cracks, could degrade large parts of the Greenland Ice Sheet faster than expected and accelerate melting toward worst-case projections for ice loss and sealevel rise, recent research (..)
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.
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.).
The latest science shows clearly that the infrastructure in Baltimore will be taxed by sealevel rise, extreme heat, and extended droughts. While weather is always variable, a stable climate helps us safeguard against the devastating impacts of extreme weather events, sea-level rise, and disruptions to essential services.
My fellowship is based on using data that trace heat-trapping emissions to major fossil fuel producers in order to understand how they have affected the climate, particularly global sealevels, and to aid efforts to hold these producers accountable.
Finally, some have suggested that the cold blob south of Greenland has been caused by increased heat loss to the atmosphere. 2022), Greenland ice sheet climate disequilibrium and committed sea-level rise, Nature Clim. Nature Climate Change, 5, 475–480, doi:10.1038/nclimate2554. 4. NASA Vital Signs, [link].
I use GCMs to provide information about large-scale conditions, processes and phenomena in the atmosphere that I can use as predictors in downscaling future climate projections. The benchmark for the evaluation was the recent ERA5 reanalysis , which probably is the best data for describing the historical state of Earth’s atmosphere.
From droughts to wildfires to rising sealevels and torrential rains, the state has felt the effects of a changing climate in a variety of ways. The increase regional VPD is mostly attributed to human-cause climate change (68%) and the rest (32%) is attributed to variations in the atmospheric circulation.
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.
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.
Sealevels are rising. The Gulf of Maine Research Institute climate dashboard clearly indicates sea surface temperature anomalies. 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. Gulf water chemistry and temperature are changing.
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.”
Also the European Climate Research Alliance ( ECRA ) is relevant with collaborative programmes on the Arctic, high-impact events, changes to the hydrological cycle and sealevel. More emphasis on methods and tools than actionable information.
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.

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. Oceans will continue to store heat and exchange it with 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. The company’s own research estimated that to prevent the average temperature from rising beyond 2 degrees Centigrade (3.6
Sealevels were quickly rising, and the rapid waters kept sediment from settling. Once the rate of sea-level rise began to slow and stabilize, the deposited sediment from the post-Ice Age era began to build up in coastal areas. Thus, barrier islands began to take shape.
In the 1960s, scientists were warning that the burning of fossil fuels was releasing carbon dioxide into the atmosphere, which could have catastrophic consequences for the planet. States and local governments are suing for damages So why are states and local governments suing the fossil fuel industry now?
So here’s the key question: How much more carbon are we going to load into the atmosphere? There are a lot of uncertainties at this point, but the biggest one is within our own hands. Every 1000 gigatons of carbon translates into about 0.5 °C C of warming. Download as PDF.
On one hand, numerous adverse effects of climate change manifest in the ocean, such as ocean acidification, temperature changes, and rising sealevels. b) to protect and preserve the marine environment in relation to climate change impacts, including ocean warming and sealevel rise, and ocean acidification?
While this has moderated atmospheric and land temperatures to some degree, the ocean can’t keep this up, and its ability to regulate the climate becomes compromised as we continue to burn fossil fuels. Warmer water also expands and raises sealevels as well as holds less oxygen.
As extreme storms become more ubiquitous, Philadelphia is among numerous cities grappling with flooding issues against the backdrop of aging infrastructure, rising sealevels and more extreme precipitation events. chance of happening in any given year, respectively. more moisture.
Massachusetts pointed to the loss of coastal land from sea-level rise, while the Urgenda judgments ultimately concluded that there is a serious risk that climate change will cause the human rights of people in the Netherlands to not be met. First, who can stand as a plaintiff?
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.
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.
