A recent study focusing on climate change brings evidence that the sea level will most likely rise to dangerous levels. There is enough ice in the Antarctica and Greenland to raise the global sea level with 23 ft. which would mean that cities like London or Shanghai would become massive swamps. 

 

The study, which was published on Thursday in the journal Nature, said that the seal level rapidly rose with 6.5 feet to 10 feet in a period of 50 to 100 years. This thing occurred about 121,000 years ago near the end of the last time period between ice ages known as an interglacial period and scientist fear that it could happen again. The findings of the study confirm the fears of dangerous sea level instability and massive ice loss. 

 

Scientists aren’t sure yet whether this big seal level rise happened quickly ore gradually. The research team mapped the ages and locations of ancient corals at an eco park in the Yucatan Peninsula to chart the time when the reefs died and other grew on higher ground. Through this method, the team of scientist managed to find out that the seal levels rose by about 10 in 50 years. The current annual rate is of 0.08 to 0.1 inch. The research team said it found out that two coral reefs around Mexico grew during the last interglacial period. 

 

This is of paramount importance. The effects of the global warming include higher temperatures, desertification, droughts mass extinctions of the University of Colorado at Boulder, of species of animals, but by far the most important effect would be a rapid increase of the sea level. With a lot of effort and vast sums of money, people would eventually find ways to counter the aforementioned effects of global warming, but the higher sea level is beyond control.  

 

However, not all coral and climate change experts agree with the study that was led by Paul Blachon and there were also three co-authors from Germany. For instance, Tad Pfeffer, of the University of Colorado at Boulder, argued that the team of researchers which carried out the study couldn’t have directly measure the rate at which the sea levels rose around the coral reefs in around Mexico due to the fact that the age estimates aren’t accurate enough. 

 

"It's an interesting idea, but one that for me is only suggestive and not compelling," Pfeffer said according to National Geographic. "I'd want to see something more solid than this if I'm going to buy the idea of such rapid sea level rise at the time [of the last interglacial]."
