Sea level rise is local. "One of the really difficult things of sea level rise is that it happens everywhere on a different pace," Frederikse says. The pace of sea level rise accelerated beginning in the 1990s, coinciding … Now, scientists and historians are racing to digitize them in an effort to understand how fast oceans are rising. Lauren Sommer reporting for NPR in March 2021. Tide gauge measurements show that global sea level rise began around the start of the 20th century. Now, scientists and historians are racing to digitize them in an effort to understand how fast oceans are rising. Global sea levels have already risen about 8 inches since 1900 on average, but in some locations, the water has risen substantially higher. "Sea level rise is not rising everywhere with the same speed. In China, the Yellow River delta is currently sinking so fast that local sea levels are rising by up to 25 centimeters per year, nearly 100 times the global average. The gathering speed of sea level rise is evident even within the space of a year, with water levels at the 25 sites rising at a faster rate in 2019 than in 2018. Places that were once covered by kilometers of ice, like northern Canada, are now rebounding upwards — which means local sea levels are actually falling in some parts of Alaska. You can read thew entire article at NPR. By 2050, sea-level rise will push average annual coastal floods higher than land now home to 300 million people, according to a study published in Nature Communications. There are two main elements to observe when assessing sea-level rise. How fast it will rise depends mostly on the rate of glacier and ice sheet melting. As the new analysis points out, models suggest that a business-as-usual climate scenario could cause nearly 1.5 degrees of ocean warming—the equivalent of nearly a foot of sea-level rise … Researchers reconstructed sea level changes over the … A century ago, the shipping industry recorded the daily ebb and flow of tides. Between 1900 and 2016, the globally averaged sea level rose by 16–21 cm (6.3–8.3 in). The aging notebooks establish a historical baseline to compare with today's changing world. Rising sea levels over the past 120 years are a result of man-made climate change and NOT variations in the Earth's orbit, study shows. The aging notebooks establish a historical baseline to compare with today’s changing world. Sea level rise is accelerating around the globe, likely to displace millions of people who live in coastal communities. The last two decades have seen global sea level rise more than twice as fast as it did in the 20th Century What is scary is that the best estimates for mid-Pliocene sea levels range from 10 … More precise data gathered from satellite radar measurements reveal an accelerating rise of 7.5 cm (3.0 in) from 1993 to 2017,: 1554 which is a trend of roughly 30 cm (12 in) per century. Tidal data like this 1930 chart provides a valuable baseline for understanding how fast oceans are rising around the globe today. How much it will rise depends mostly on the rate of future carbon dioxide emissions and future global warming.
