The new research has cast doubts on the warnings that rising sea levels caused by climate change are ! slowly inundating low-lying pacific islands. The j scientists have studied 27 low-lying pacific islands, j comparing the aerial photos from 60 yr ago with ! modern satellite images, according to a recent research. Paul Kench of the university of Auckland in New Zealand and Arthur Webb at the South Pacific applied Geoscience Commission in Fiji have found that only four out of the 27 islands have declined in size despite an average rise in sea level by 12 cm during the 60 yr period. Half of the rest remained the same size while the other half of the islands had increased in size during this period. Kench says — “It is clear that islands respond in different ways to climate changes and rising sea levels. There is no one model that fits into all kinds of scenarios. It was important to have a sensible debate over the impact of climate change rather than just saying the sea level is going up and the islands must all disappear.” Which of the following is not in consonance with the contents of the passage?

Although, the study involved only the land area, Kench says his previous researchers had shown that cyclones and storms — which are predicted to become more frequent with climate change — also often played an important role in increasing the heights of the islands.
The study shows that some islands are growing because waves, currents and winds are pushing coral debris from the surrounding reefs onto the shore.
The study is very important and relevant but not very reliable. The modern methods of taking the aerial views and measurement of these islands through satellite images is far more accurate and comparing them with 60 yr old conventional maps is not logical. We may compare today’s results with new data taken after 5-10 yr and then draw the conclusions.
The study found seven islands having grown in area by more than 3% on an average since the 1950s with one island expanding nearly by 30%.
