World iconic glaciers set to disappear by 2050 due to rising temperature: UNESCO


New Delhi: Some of the world’s most iconic glaciers are set to disappear by 2050 due to increasing temperature, according to a new study by UNESCO.

“Glaciers in a third of sites are under threat, regardless of efforts to limit temperature increases” it said.

However, the study outlines that it is still possible to save the other two-thirds, if the rise in global temperatures does not exceed 1.5°C compared to the pre-industrial era

Fifty UNESCO World Heritage sites are home to glaciers, representing almost 10% of the Earth’s total glacierized area.

The UNESCO study, in partnership with the International Union for Conservation of Nature (IUCN), showed that these glaciers have been retreating at an accelerated rate since 2000 due to CO2 emissions, which are warming temperatures.

The study said that, “They are currently losing 58 billion tons of ice every year – equivalent to the combined annual water use of France and Spain – and are responsible for nearly five per cent of observed global sea-level rise.

“The glaciers under threat are in Africa, Asia, Europe, Latin America, North America and Oceania” the agency said.

Raising concerns over the development, Audrey Azoulay, UNESCO’s Director-General said that,“This report is a call to action. Only a rapid reduction in our CO2 emissions levels can save glaciers and the exceptional biodiversity that depends on them.

“COP27 will have a crucial role to help find solutions to this issue. UNESCO is determined to support states in pursuing this goal,” she added.

In addition to drastically reduced carbon emissions, UNESCO is advocating for the creation of a new international fund for glacier monitoring and preservation.

Half of humanity depends directly or indirectly on glaciers as their water source for domestic use, agriculture, and power. Glaciers are also pillars of biodiversity, feeding many ecosystems.

“When glaciers melt rapidly, millions of people face water scarcity and the increased risk of natural disasters such as flooding, and millions more may be displaced by the resulting rise in sea levels”, said IUCN Director General Dr Bruno Oberle.

“This study highlights the urgent need to cut greenhouse gas emissions and invest in Nature-based Solutions, which can help mitigate climate change and allow people to better adapt to its impacts” said Oberle.
