Global warming is causing the ice at the poles to melt which in turn causes the level of world oceans to rise. Consequently all shorelines are receding.
Climate change is eliminating giant chunks of ice from Greenland at such a speed that the melt has already made a significant contribution to sea level rise, according to a new study. With global warming, the island will lose much more, threatening coastal cities around the world. Forty percent to 50% of the planet's population is in cities that are vulnerable to sea rise, and the study published Monday in the Proceedings of the National Academy of Sciences is bad news for places like New York, Miami, Los Angeles, Tokyo and Mumbai.
Researchers reconstructed the mass balance of the Greenland Ice Sheet by comparing estimates of the amount of ice that has been discharged into the ocean with the accumulation of snowfall in the drainage basins in the country's interior for the past 46 years. The researchers found that the rate of ice loss has increased sixf old since then -- even faster than scientists thought.

All shorelines are receding however this was portrayed in the Quran long before it was discovered:
(Quran 13.41) Do they not see how We deal with the land (الْأَرْضَ), diminishing it at its edges? Allah judges; and nothing can hold back His judgment. And He is quick to settle accounts.
In Arabic Ard الْأَرْضَ means "Earth" and it also means "Land". Shores are edges of the land. Land is diminishing at its edges because of rising sea waters.
How could an illiterate man who lived 1400 years ago have known about receding shores?
The water cover about 71% of the Earth's surface. This is also the same ratio the word "Water" and word "Land" appear in the Quran. "Water" 32 times and "Land" 13 times. The ratio of "Water" to the total (Water + Land) = 32/(32+13) = 71%.
(The Christian Bible says that Earth floats over water Psalms 136:6)
