The circumference has risen 18 cm since 1900

Scientists have conducted detailed analyzes of sea level based on cave deposits found in Mallorca In Spain, where there are more than 1,000 cave systems. In some of them, you can find sediments formed millions of years ago, which are very valuable Geo-archiving Environmental changes occurring on Earth.

To determine the ocean level, scientists focused on analyzing sediments less than 4,000 years old. They discovered a previously unknown one that measures about 20 cm in length ocean level riseWhich happened 3200 years ago. Then naturally The ice caps were meltingwhich disappeared at a rate of 0.5 mm per year over the course of 400 years.

Scientists recorded this despite large natural climatic changes such as The perfect climate in the Middle Ages And the Little Ice Agesea level remained remarkably stable until 1900. The gradual development of the steel, electrical and automobile sectors resulted indirectly rapid climate changeResulting in increased ocean levels. Since the beginning of the twentieth century, the sea level has risen by 18 centimeters.

Scientists took 13 samples from eight caves next to it The Mediterranean Coast. Suitable research deposits are extremely rare because they only form near the shoreline in the corridors of caves frequently flooded with seawater. Thanks to this, these places are perfect signs sea ​​level changes.

Based on ice weight loss analysis from green land And the AntarcticaThe average sea level rise since 2008 has been 1.43 mm per year.

Even if we stop now, sea levels will continue to rise for at least several decades, if not centuries, simply because the system is hot. – Inform the professor. Unak
