Sea levels are at the steepest increase in 2,000 years according to a recent research done in the US. The unexpected rise poses a threat to coastal cities or cities near the sea, where 50% of the US’ population resides. Researchers suggest that climate change may be the cause of such rate.

According to researchers from University of Pennsylvania, the sea level has been rising 0.08 inches every year since the 19th century. Previous data from fossils show that levels of water remained stable during the early years of the 2,000 period, specifically around 200 BC to AD 1,000.

Furthermore, the researchers say that based on historical records, global temperatures affect sea levels. For instance, the rise of sea level during the 11th century happened at the same time as the mysterious climate change during the medieval age. As the data suggest, sea levels rise when temperatures rise.

This data can help researchers understand the effect of global temperature to the sea level.  If they are able to accurately predict the changes in sea level based on the data from the past, they can predict how much the sea level will rise in the future.
