According to Source,Humans-induced greenhouse gases are increasing sea levels. The climate change is amplifying regional sea rise changes in Bay of Bengal, the Arabian Sea, Sri Lanka, Sumatra and Java. The rise could threaten lives in Bangladesh and India, causing massive floods in monsoons.
An enormous area of the tropical oceans stretching from the east coast of Africa west to the International Date Line in the Pacific has heated by about 1 degree Fahrenheit, or 0.5 degrees Celsius, in the past 50 years, said CU-Boulder Associate Professor Weiqing Han, lead study author.
“Our new results show that human-caused changes of atmospheric and oceanic circulation over the Indian Ocean region are the major cause for the regional variability of sea level change,” wrote the authors.
“It is important for us to understand the regional changes of the sea level, which will have effects on coastal and island regions,” said Hu.
