That climate scientists looking into rising sea levels are currently directing their research at the massive ice caps of the Arctic and the Antarctic is hardly surprising. After all, it is estimated the West Antarctica region alone – a mass of land the size of Greenland and home to natural behemoths such as the Pink Island Glacier – is responsible for ten per cent of the global sea level rises seen over the past few years.

However, the findings of a new study suggest that it will be the ‘melt off’ from smaller mountain glaciers and inland ice caps, rather than from the world’s biggest ice shelves, that will drive sea level increases over the coming decades. This new research, which was carried out the University of British Columbia, saw a team of climatologists develop a simulation capable of modelling anticipated volume loss and melt off from some 120,000 sites around the world between now and 120,000. Unlike previously-developed models, this time around the scientists made an effort to achieve detailed projections per region instead of merely focusing on wider trends.

“There is a lot of focus on the large ice sheets but very few global scale studies quantifying how much melt to expect from these smaller glaciers that make up about 40 percent of the entire sea-level rise that we observe right now,” lead researcher Valentin Radic, from the Department of Earth and Ocean Sciences at UBC, explained, writing up the findings in the academic journal Nature Geoscience.
