Last year, the National Aviation and Space Administration said, last year, a “unexpected” quantity of sea levels witnessed all over the world.
An analysis led by the agency found that the height rate was nearly a quarter of an inches annually, compared to The expected rate From 0.17 inches.
This raises statistics given the increasing risks that sea levels bring, including sending fatal storms at home, The threat of urban infrastructureCoast erosion and Disable ecological systemsWhich led to more frequent floods.
“The height we saw in 2024 was higher than what we expected,” said Josh Willis, a sea surface researcher at NASA in southern California. statement. “Every year it differs slightly, but what is clear is that the ocean continues to rise, and that the rate of height increases faster and faster.”
NASA said that the increase was due to an “unusual” amount of ocean temperature, in addition to the flow of melting water from ice flowers and other wild ice.
As the Earth’s temperature rises due to greenhouse gas emissions, more than 90 percent of this heat is absorbed by the oceans. This causes the ocean temperatures to rise and the expansion of water. It is a process known as “thermal expansion” that contributes to high sea levels. The high temperature of the planet has caused approximately a third of the world’s surface level, which was noticed by satellite measuring devices since 2004.
While thermal expansion was the main reason-and is responsible for nearly two-thirds of the sea level-about a third also came from the melting of ice panels and ice rivers.
The ice cover in Antarctica dissolves at an average rate of about 150 billion tons annually, and Greenland loses about 270 billion tons annually, adding to the rise in sea level. The loss of the ice cover in Greenland is equivalent to the weight of 26,000 Eiffel Towers, according to Lamont-Dooherty Earth from Columbia University.
If all icy rivers and ice panels melted, the world’s surface level will rise More than 195 feetHeight only Its length is more than 10 feet from the space shuttle.
The warming that has led to these operations has become more severe in recent years. Last year was also designed to be The warmest year everWith global temperatures 2.3 degrees above the average of the twentieth century in NASA from 1951 to 1980.
“With the year 2024, with a warmer record, it follows the expanding surroundings of the Earth, reaching the highest levels in three decades,” said Nadia Vinjardova Cheff, head of physical ocean science programs and an integrated Earth system at NASA headquarters.
Continuous increases It is likely to lead to anxious future Without huge work to stop greenhouse gas emissions. Central estimates of the non -profit group of climate from more than four million acres of American real estate It is expected to be at least at least less than the tidal lines by 2050.
