For almost 240 million people, the Hindu Kush Himalaya (HKH) region’s glaciers provide as a vital source of water.
Scientists cautioned Tuesday that the Why Himalayan glaciers are melting || ہمالیہ کے گلیشیئر کیوں پگھل رہے ہیں that provide almost two billion people with essential water are melting more quickly than ever before as a result of climate change, putting communities at risk of unpredicted and expensive calamities.
According to a study by the International Centre for Integrated Mountain Development (ICIMOD), the glaciers melted 65% more quickly between 2011 and 2020 than they had over the prior ten years. Ice will melt as it warms up; this much was known, but the speed at which it does so is unexpected and extremely concerning, according to main author Philippus Wester. The pace of this is far faster than anticipated.
According to the paper, glaciers in the Hindu Kush Himalaya (HKH) region are an essential supply of water for 1.65 billion people living in river valleys below and 240 million people who live in mountainous areas.
According to the Nepal-based ICIMOD, an intergovernmental organisation that also has member nations Afghanistan, Bangladesh, Bhutan, China, India, India, Myanmar, and Pakistan, the glaciers could lose up to 80% of Using current emission trajectories, their volume towards the end of the century.
The glaciers directly or indirectly provide billions of people with food, energy, clean air, and revenue by feeding ten of the most significant river systems in the world, including the Ganges, Indus, Yellow, Mekong, and Irrawaddy.
The ramifications of losing this cryosphere (a frozen zone), which supplies water to two billion people in Asia, are “too great to contemplate,” according to Izabella Koziell, deputy chief of ICIMOD.
The peer-reviewed assessment stated that even if global warming is kept within the 1.5 to 2.0 degrees Celsius from pre-industrial levels set forth in the Paris climate pact, the Why Himalayan glaciers are melting || ہمالیہ کے گلیشیئر کیوں پگھل رہے ہیںbetween a third and a half of their volume by 2100, according to predictions.
It emphasises the necessity of quick climate action, according to Wester.”Even the smallest action will have a significant impact, so we implore you to act now to slow down climate change.”
Predictions might be achieved with a high degree of accuracy, according to Wester, thanks to developing technologies and previously restricted high-resolution satellite imagery.
Why Himalayan glaciers are melting || ہمالیہ کے گلیشیئر کیوں پگھل رہے ہیں Since the middle of the 1800s, the world has warmed by an average of approximately 1.2 C, causing a variety of extreme weather events, such as more intense heatwaves, more severe droughts, and storms that are made more fierce by rising sea levels.
The world’s poorest nations, who have contributed little to the fossil fuel emissions that have increased temperatures, and the most vulnerable individuals have been hardest harmed.
Amina Maharjan, an expert in migration and livelihoods at ICIMOD, claimed that communities lack the assistance they require.
“Communities and households are primarily responsible for adaptation (to climate events).” It is insufficient to handle the problems brought on by climate change, according to Maharjan.
“Anticipating change is going to be very important moving forward,” she said.
