Over the past few decades, sea levels worldwide have risen because of three primary phenomena related to climate change: the expansion of warming oceans, the input of fresh water from melting ice sheets and the loss of ice mass from Greenland and Antarctica Rising seas threaten millions of people who live in densely populated coastal areas and low-lying islands, so it is critical for risk management purposes to estimate and prepare for the impacts of future sea-level rise and to be aware of regional differences.
Detailed sea-level records provide testimony of sea-level rise over the past two decades, but shoreline monitoring and the detailed study of changes in island morphology are lacking. Given the international concern for the stability of small islands, it is important to complement sea-level records with quantified measures of reef-island changes at the same temporal scale to better inform the management of island landscapes in the face of climate change.
Southern India is more prone to weather extremes as the earth warms up, according to a study by the Indian Institute of Technology (IIT) in Gandhinagar.
The earth is expected to warm up somewhere between 2.6 degree and 8.5 degree Celsius over the century. The study, published recently, also states that compared to the worst-case scenario, the best-case scenario will cut down the severity and frequency of floods by 50%. “South India is more sensitive to changes in temperature,”
