NEW DELHI: As various parts of the world, including India, struggle with extreme heatwaves exacerbated by the El Niño trend, waters are experiencing major adjustments too. Recent information indicates that the global sea levels are rising at a faster rate, which raises the risk of coastal erosion and flood.
Current research indicates that the average sea level on the planet increased by 0.76 meters between 2022 and 2023 only. This is a significant increase, according to experts, and is linked to a heat climate and the development of a significant El Nio event.
The thorough investigation by NASA, which covers more than 30 years of dish observations since 1992, reveals a significant increase in water levels. Sea levels have increased by about 9.4 centimeters since 1993, according to data from the Sentinel- 6 Michael Freilich goal, which was launched in November 2020. The rate of increase has accelerated from 0.18 inches per year in 1993 to 0.42 inches per month now.
Nadya Vinogradova Shiffer, chairman of NASA’s sea level change group, predicts that water levels may rise an extra 20 inches by 2050. This planned rise has a roughly doubled increase over the past century, which could increase the frequency and severity of flooding incidents around the world.
Sea levels are also affected by the interaction between the La Nio and El Nio processes. La Nia, which has cooler Pacific waters, tends to lower water levels by redistributing precipitation from the sea to the property. In comparison, El Niño, with its cooler Pacific waters, raises water levels by increasing sea precipitation. These processes cause temporary swings, but they also overlay a long-term pattern of rising sea levels caused by global warming.
Researchers use sensor altimeters to measure these changes, which allow accurate calculations of ocean level. They send microwave signals to the ocean surface and get them back. These data are supported by data from sea meters and other satellite devices.
Scientists can learn about the complexity of global sea level changes thanks to this thorough and creative foreign dataset. By integrating data on sea temperatures, snow loss, and land movements, researchers gain complete insights into the continued impacts of climate change on our oceans and coasts.
The findings highlight the urgency of addressing climate change and its long-term effects on the planet as the world continues to warm.
