Existence Of World Heritage Sites’ Glaciers Under Threat

SCIENCE-TECH

A recent study on the effects of greenhouse gases has revealed that it the greenhouse gases’ emissions remain unchecked then almost half of the world’s heritage glaciers – 21 of the 46 natural world heritage sites where glaciers are found – could become ice-free by 2100.

This could affect some of the most iconic glaciers of the world and these include the Grosser Aletschgletscher in the Swiss Alps, Khumbu Glacier in the Himalayas and Greenland’s Jakobshavn Isbrae.

It was a comprehensive study carried out by the scientists who combined data from a global glacier inventory and sophisticated computer modelling to analyse the current state of world heritage glaciers, their recent evolution, and their projected mass change over the 21st century.

The study published in the journal Earth’s Future, it was stated that even under a low emission scenario, eight of the 46 world heritage sites would be ice-free by 2100.

The study also predicts 33-60 per cent of the total ice volume in 2017 will be lost by 2100, depending on the emission scenario.

The study further revealed that the Los Glaciares National Park in Argentina, Waterton Glacier International Peace Park, Canadian Rocky Mountain Parks and Olympic National Park in North America, the Pyrenees – Mont Perdu in Europe and Te Wahipounamu in South West New Zealand are some of the iconic landscapes, which would be impacted by the rising temperatures.
