NASA has recently revealed that sea levels are now rising at an incredibly fast pace all around the globe. Although not much is known about the topic yet, a NASA model observed the changes in sea level by collecting data from satellites ever since 1992.
“By combining space-borne direct measurements of sea level with a host of other measurements from satellites and sensors in the oceans themselves, NASA scientists are not only tracking changes in ocean heights but are also determining the reasons for those changes” said Michael Freilich, who is the director of NASA’s Earth Science Division at the agency’s headquarters in Washington, D.C. The news was released at a press conference on August 26.
He also said that sea level rise is the most obvious and visible result of climate change. This will obviously have a very big impact on the planet, including the economy and people’s general wellbeing.
The NASA experts have listed three main causes for sea level rise: melting ice sheets in Antarctica and Greenland, melting glaciers all over the globe and the expansion of water due to higher temperatures.
Some might say that sea level rise is not necessarily something new, but scientists warn that this increase is occurring much faster than it did five decades ago. Moreover, it is expected that the speed at which water will spread will be higher in the years to come, due to the melting sheets.
“It’s pretty certain we are locked into at least three feet of sea- level rise, and probably more, but we don’t know whether it will happen within a century or somewhat longer,” said Michael Freilich.
This is very worrying information, given the fact that there are many people who live so close to the sea, especially in Asia. Major cities, such as Tokyo, Singapore, but also Florida in the United States and many islands could disappear over the next decade.
Even if global warming is irreversible, authorities are looking into ways of keeping the increase in temperature to less than 3.6 Fahrenheit degrees by 2100.
