Sea Level Rise Technical Report and Useful Interactive Tools from NOAA for 2022

Researchers from the U.S. government have released a thorough new report containing data and maps that demonstrate high tide flooding over the Atlantic, Pacific, and Gulf coasts. The report discusses how flooding has occurred, how it is expected to continue, and how flooding will get worse (exponentially). By April 2023 and 45 to 70 days per year by 2050, flooding will be a national average of 3 to 7 days per year. The research claims that during the course of the previous year, coastal regions were inundated more than 500 times by high tides caused by increasing seas. The Atlantic and Gulf coasts are now more regularly troubled by high tide and coastal flooding than they were in 2000.

The most recent sea level rise projections are provided for all U.S. states and territories in the Sea Level Rise Technical Report. The most recent development since 2017 is this multi-agency endeavor. NOAA , NASA , Environmental Protection Agency , U.S. Geological Survey , Federal Emergency Management Agency , and Army Corps of Engineers are just a few of the 23 co-authors on the technical paper, which is the most recent output of the Sea Level Rise and Coastal Flood Hazard and Tools Interagency Task Force.

In order to assist communities in assessing anticipated changes in average tide heights and height-specific threshold frequencies as they work to adapt to sea level rise, the paper includes forecasts out to the year 2150.

This study provides interesting datasets. Maps offer crucial information on where flooding dangers are currently and where they will increase via the Sea Level Rise Scenario Tool . The report’s new report 0 underlines the challenges that ecosystems and communities face.

I discovered several ways for the visually inclined person to better comprehend climatic information as I read this study. I hope that cities would use these to enhance their policies based on information, knowledge, and science (rather than vested interests trying to steady folks in denial ). As an illustration, one may simply explain, even a kid, how coastal homes suffer difficulties and loss as well as the threats of climate change in the years to come by utilizing one of the many tools ( new report 2).

You may more quickly observe and comprehend several contributing elements and what they result in by using the interactive graphic What Contributes to Coastal Flooding?, as you can see above.

Additional tools and resources from the report:
One portion assists people by posing and responding to important real-world topics.
How high does the water have to rise before there is an issue?
When do we anticipate that to occur?

Breathe, the detailed process is lengthy, but with the aid of these tools, people can actually find assistance. This can be done on a personal, community, or even more substantial state or federal level. These resources can be used by municipal council members, regular citizens, and urban planners.

Coastal communities can make decisions regarding the existing and future capacities of their stormwater management systems in the face of coastal flooding using the data provided from the Quick Flood Assessment Tool in the new report 4 section and the techniques presented in the new report 5 part.

Highlights from the report’s new report 0 on the challenges communities and ecosystems confront include:

The U.S. Sea Level Rise and Coastal Flood Hazard Scenarios and Tools Interagency Task Force produced this report and the datasets that go along with it. They provide 1) sea level rise scenarios to 2150 by decade that include estimates of vertical land motion, and 2) a set of extreme water level probabilities for different heights along the U.S. coastline. Along the U.S. coastline, these data are accessible in 1-degree grids and explicitly downscaled at NOAA tide-gauge stations. Estimates of flood exposure are determined using current U.S. coastal flood-severity thresholds for the next 30 years (out to the year 2050), assuming no new risk reduction measures are implemented, and for the current conditions (such as sea levels and infrastructure footprint).

This initiative expands upon the Task Force report from 2017 (Sweet et al., 2017). The NASA Sea Level Change Team, in particular, updated and downscaled the set of global mean sea level rise scenarios from that report using output directly from the IPCC’s Sixth Assessment Report (AR6; IPCC, 2021a); updates included adjusting the temporal trajectories and exceedance probabilities of these scenarios based on end-of-century global temperatures. These global mean sea level rise scenarios for the U.S. coastline are regionalized, similar to the 2017 report. Additionally, the severe sea level dataset that was newly created for this paper is adapted using technique that supports the U.S. Department of Defense Regional Sea Level (DRSL) database1 (Hall et al., 2016).

A crucial technical contribution for the Fifth National Climate Assessment will come from this report (NCA5). The NOAA Sea Level Rise Viewer and Inundation Dashboard, NASA’s Sea Level Change Portal, and other government products and services are among those that are incorporating these data and information. This report’s objective is to inform Federal agencies, state and local governments, and stakeholders in coastal communities about current and future sea level rise in order to help contextualize its effects for decision-making purposes, even though it does not have the authority to offer design specifications or authoritative guidance for a specific project.

ESSENTIAL TEXTS The data is intended to educate stakeholders in coastal areas, state and municipal governments, and federal agencies on current and projected sea level rise. Its purpose is to facilitate more meticulous and informed decision-making.

Key Message #1: Multiple lines of evidence improve confidence in a narrower range of anticipated global, national, and regional sea level rise at 2050 than previously reported, regardless of the emissions trajectory (Sweet et al., 2017).

Key Message #2: Major and moderate high tide flood events will occur as frequently as moderate and minor high tide flood events already do by 2050 due to the predicted relative sea level (RSL), which will cause tide and storm surge heights to rise. Without additional risk-reduction measures, there will be serious repercussions for the infrastructure, populations, and ecosystems along the U.S. coast.

Key Message #3: The likelihood that sea levels will rise by the end of the century and beyond is increased by greater global temperatures. The relative sea level projections for the coastline of the Contiguous United States (CONUS) are approximately 0.62.2 m in 2100 and 0.83.9 m in 2150 (relative to sea level in 2000); these ranges are influenced by the response of the underlying physical processes and uncertainty in future emission pathways.

#4 Key Message In order to assess scenario divergence and track the trajectory of observed sea level rise, it is essential to keep track of the sources of current sea level rise as well as the processes that are responsible for sea level changes. This is especially true during the time when projected sea level rise ranges are likely to increase due to future emission pathways.

new report 6

1. The Rise in Sea Level During the Next 30 Years: According to projections, the sea level along the U.S. coastline will rise by an average of 1012 inches (0.250.30 meters) over the next 30 years (20202050), which is equal to the rise over the previous 100 years (19202020). Regional variations in sea level rise along the U.S. coasts will result from changes in both land and ocean height. new report 7


2. More Negative Flooding: Over the next 30 years, sea level rise will result in a significant change in coastal flooding as tide and storm surge heights rise and extend further inland. On average, moderate (usually destructive) flooding is predicted to happen more than ten times as often by 2050 than it does now, and local conditions may make it worse. new report 8

3. Emissions Matter: Both recent and upcoming emissions are important. The likelihood of a sea level rise of about 2 feet (0.6 meters) along the U.S. coastline between 2020 and 2100 is rising as a result of current emissions. By the end of this century, failure to reduce future emissions might result in a rise of an additional 1.5 5 feet (0.5 1.5 meters), for a total of 3.5 7 feet (1.1 2.1 meters). new report 9

4. Ongoing Monitoring: Monitoring the ways and causes of sea level change is crucial for understanding adaptation strategies. We are now able to track sea level fluctuations in a way that has never been conceivable thanks to our ability to monitor and comprehend the various elements that contribute to sea level rise (e.g., using satellites to track global ocean levels and ice sheet thickness). As sea levels rise, ongoing and extended monitoring will be essential. Sea Level Rise Viewer 0

PERIODICAL THOUGHTS CONSIDER THE TOOLS THROUGH THIS REPORT, AND FEEL BETTER. Every day, scientists, researchers, farmers, gardeners, and environmentalists put in a lot of effort, are compassionate, and seek to solve the climate and environmental challenges facing our planet.

A fantastic essay to think about was written a while ago by Scott Cooney. An example: The same is true of climate change. It is intricate. On a global scale, it is difficult to comprehend how gases like carbon dioxide, methane, and others trap heat. It’s difficult to comprehend the heat generated by the internal combustion engines used by the seven billion people on the planet.

Having said that, I believe that reading this study is a helpful action for anyone who does so, whether they are a youngster, an adult, or an urban planner. Can’t stop reading it. Because it is practical, accurate, educational, and full of tools for answers to infrastructure issues that must be addressed directly, it has lifted my spirits in the midst of the depressing news from this planet.

However, be mindful of how quickly Sea Level Rise Viewer 1.
