Cave walls are records of warming and sea-level elevations

I thought the Mahdi

The study of giant rock formations inside the Arta caves on the Spanish coast of Mallorca has helped scientists to date the movement of the seas as the temperature changes.

On August 30, 2019, a joint study by the University of South Florida, Columbia University, the University of New Mexico and the University of the Balearic Islands of Spain was published in the journal Nature.

This study indicates that saltwater sea polishes were refined by bulb-shaped stalactites 4.39 million years ago, leaving their effects at altitudes that are significantly higher than current sea-level rates.

The climate of the Pleocene era will return
The study shows that the sea level was 16 meters higher than it is now.

The Earth was known for its warm climate at the time, and scientists predict that the Earth's warm climate will return by 2100 as a result of global warming.

This study provided the most accurate view yet of what might happen as a result of climate change and the melting of ice sheets from sea-level rise and the oceans, a process that would take hundreds of thousands of years to occur.

Scientists expect the study to put them on track for further work to predict the impact of melting ice sheets on the continent on the ocean's rise.

The team found that although smaller ice sheets melted in Greenland and western Antarctica, the large parts of the east ice sheet melted as they slid into the ocean's waters at the time.

Traces of metals in stalagmites and descendants
Climatic scientists used to use two methods to map sea-level changes, the first of which is to compare two types of oxygen or isotopes found in fossilized marine organisms with a global record of oxygen ratios and ice cycle cycles.

The second method relies on the use of old coral reefs, to estimate ancient sea levels.

In their current study, scientists searched the caves for evidence of past sea level changes. The team investigated the formation of mineral deposits in stalagmites and condoms that were deposited over hundreds of thousands of years as a result of the impact of seawater on the cave walls.

They compared uranium ratios to lead in metals to determine when the ancient pliocene deposits formed.

The researchers found that rising water levels in the Pliocene era have left mineral deposits at altitudes ranging from 14.7 to 23.5 meters above sea level today.

Climate scientists predict that global temperatures will rise by 2-3 degrees Celsius by 2100, accompanied by a return to sea level to 4.39 million years ago.
