What Will Sea Levels Look Like In 2050 – NASA, NOAA, USGS and other US government agencies predict that sea level rise in the next 30 years could match the total rise seen in the last 100 years.

Coastal flooding will increase dramatically over the next 30 years due to sea level rise, according to a new report from an interagency sea level task force that includes NASA, the National Oceanic and Atmospheric Administration (NOAA) and other government agencies. The report, dated February 15, 2022, called Global and Regional Sea Level Rising Scenarios for the United States, concludes that sea levels along the U.S. coast will rise between 10 and 12 inches (25 and 30 centimeters) on average above what today is the year 2050.

The report – an update of the 2017 report – predicts sea levels up to 2150, providing for the first time a close forecast for the next 30-year period. Agencies at the federal, state, and local levels use these reports to inform their plans to anticipate and respond to the effects of sea level rise.

Rising Sea Levels Rise

The report supports previous research and confirms what we’ve known for a long time: Sea levels continue to rise at an alarming rate, putting communities around the world at risk. The science is undisputed, and urgent action is needed to mitigate the ongoing climate crisis,” said NASA Administrator Bill Nelson. “NASA emphasizes our commitment to protecting our home planet by expanding our monitoring capabilities and continuing to ensure that our climate data is not only accessible but understandable.”

The task force improved its predictions of short-term sea level rise by taking advantage of the increased understanding of how the processes that contribute to sea level rise – such as the melting of glaciers and ice sheets and the complex interactions between ocean, land and ice – will affect sea level rise. “This understanding has improved significantly since the 2017 report, which gave us more certainty about how much sea level will rise in the coming decades,” said Ben Hamlington, a research scientist at NASA’s Jet Propulsion Laboratory in Southern California and one of them. lead authors of the review.

NASA’s Sea Level Change Team, led by Hamlington, also developed an online mapping tool to visualize the report’s projections of sea level rise at local levels in the United States. “The hope is that the online tool will help make the information as accessible as possible,” Hamlington said.

The Interagency Sea Level Rise Task Force predicts an increase in the frequency and severity of coastal flooding, known as nuisance flooding, due to sea level rise. It also notes that if greenhouse gas emissions continue to rise, global temperatures will increase further, making it more likely that sea-level rise by the end of the century will exceed the 2022 replacement projections.

“It takes a village to predict the weather.” When you combine NASA’s global sea level rise scenarios with NOAA’s high water level estimates and US impact studies. Geological Survey, you get a solid national estimate of the projected future that awaits American coastal communities and our economic infrastructure in 20, 30 or 100 years,” said Nadya Vinogradova Shiffer, who leads NASA’s Sea Level Change Team at NASA Headquarters in Washington.

“This is a global wake-up call and gives Americans the information they need to take action now to better position us for the future,” said NOAA Administrator Rick Spinrad, Ph.D. “As we build a climate-ready nation, this updated data can inform coastal communities and others about current and future risks in the face of climate change and help them make smarter decisions to keep people and property safe in the long term.”

The Global and Regional Sea Level Rise Report contains sea level projections from the most recent assessment of the Intergovernmental Panel on Climate Change (IPCC), published by the United Nations in August 2021. The IPCC reports, published every five to seven years, provide a global assessment of the world. weather and usage analysis based on computer measurements, among other things.

A special forthcoming report called the Fifth National Climate Assessment, produced by the US Global Change Research Program, is the latest in a series summarizing the effects of climate change on the US and will use findings from Global and Regional. Sea level rise report on its analysis. The climate assessment is expected to be published in 2023.

Sea Level Rise

NASA sea level scientists have years of experience studying how Earth’s changing climate will affect the oceans. Their work includes forecasting research on how much coastal flooding the US will experience in 10 years, helping to visualize IPCC data on global sea level rise using an online visualization tool, and launching satellites which provide data on decades of world record highs. .

The authors of a paper published Tuesday developed a more accurate method of calculating land elevation from satellite readings, a common method for estimating the effects of sea-level rise over large areas, and found that previous figures were too optimistic. New research shows that up to 150 million people now live in a world that will be under the flood line by mid-century.

The first map shows what is expected of the world being submerged in 2050. But the new sample, the second map, shows that the lower part of the country will be under water during high tides.

Much of Ho Chi Minh City, the country’s economic hub, will also disappear, according to the study, produced by Climate Central, a New Jersey-based science organization, and published in the journal Nature Communications. The projections do not take into account future population growth or land lost to coastal erosion.

Traditional satellite altimetry has difficulty distinguishing true ground level from the tops of trees or buildings, said Scott A. Kulp, a scientist at Climate Central and one of the paper’s authors. So he and Climate Central CEO Benjamin Strauss are using artificial intelligence to determine the extent of the errors and correct them.

In Thailand, more than 10 percent of citizens now live on land that could flood by 2050, compared to 1 percent under the previous estimate. The capital of politics and business, Bangkok, is in grave danger.

Climate change will put pressure on cities in many ways, said Loretta Hieber Girardet, a Bangkok resident and UN disaster reduction chief. Even if global warming fills many areas, it will also push poor farmers to seek work in cities.

But even with that investment, defensive measures can only go so far. Mr. Strauss gave the example of New Orleans, an underwater city that was destroyed in 2005 when its high tide and other defenses failed during Hurricane Katrina. “How deep a container do we want to live”? he asked.

Above all, research shows that countries should start now to prepare more citizens to immigrate, according to Dina Ionesco of the International Organization for Migration, an intergovernmental group that links action on migration and development.

“We’ve been trying to ring the alarm bells,” Ms Ionesco said. “We know you’re coming.” There is little modern precedent for this mass migration, he added.
