There is a third pole on earth, and it’s melting quickly

When we think of the world’s Polar Regions, only two usually spring to mind – the North and South. However, there is a region to the south of China and the north of India that is known as the “Third Pole”.

That’s because it is the third largest area of frozen water on the planet. Although much smaller than its north and south counterparts, it is still enormous, covering 100,000 square kilometres with some 46,000 glaciers.

Scientists conducting research in the area have warned of disturbing global warming trends, and how, if they continue, they could affect the lives of 1.3 billion people

The Hindu Kush-Himalayan region spans an area of more than 4.3 million square kilometres in Afghanistan, Bangladesh, Bhutan, China, India, Myanmar, Nepal, and Pakistan. The region stores more snow and ice than anywhere else in the world outside the polar regions, giving its name: ’The Third Pole‘. The Third Pole contains the world’s highest mountains, including all 14 peaks above 8,000 metres, is the source of 10 major rivers, and forms a formidable global ecological buffer.

The Third Pole region has enormous socioeconomic and cultural diversity; it is home to many different ethnic communities speaking more than 600 languages and many more dialects. It is endowed with rich natural resources and contains all or part of four global biodiversity hotspots. The mountain resources provide a wide range of ecosystem services and the basis for the livelihoods to the 210 million people living in the region, as well as indirectly to the 1.3 billion people — one fifth of the worlds’ population — living in the downstream river basins. More than 3 billion people benefit from the food and energy produced in these river basins that have their origin in the mountains.

The Third Pole and Climate Change:

Climate change has become a major concern in the Third Pole. Mountain systems are particularly sensitive to climate change and the Third Pole region is home to some of the people most vulnerable to these changes in the world. Changes in the river systems and their basins have impacted directly on the wellbeing of millions of people.

The rate of warming in the Third Pole region is significantly higher than the global average, and the rate is higher at higher altitude, suggesting a greater vulnerability of the cryosphere environment to climate change. This trend is expected to continue.

Climate change projections suggest that all areas of South Asia are likely to warm by at least 1°C by the end of the century, while in some areas the warming could be as high as 3.5-4°C. The life and livelihoods of the people in the Third Pole region is challenged due to climate change, and the stability and prosperity of the region affected by the Third Pole is at risk, which will have implications for all of Asia and for the world.

However, there is still little knowledge of this situation, and its potential implications, outside the immediate vicinity; a special effort is needed to raise awareness of the fragility of the mountain social-ecological system.

The melting of glaciers of the Third Pole could affect the lives of 1.3 billion people because of its proximity to densely populated and industrialised regions. And the continuous melting of glaciers will be catastrophic for the people who depend on water from the Third Pole.
