The Himalayas are warming up faster than the plains, and it's not just a distant concern. A recent study by researchers at IIT Kharagpur has revealed that several high-altitude regions of Jammu and Kashmir have warmed by nearly 1 degree Celsius over the past two decades. This is a cause for alarm, as it highlights the uneven impact of climate change on mountain regions. The study, published in Scientific Reports, analyzed 44 years of weather data and identified a clear pattern of Elevation-Dependent Warming (EDW), where temperatures are rising much faster at higher elevations than in the plains. This is particularly concerning for tourist destinations such as Pahalgam and Gulmarg, which are experiencing the fastest warming. The study attributes this to a phenomenon known as the snow-albedo feedback loop. As temperatures rise, seasonal snow melts earlier, exposing dark mountain rocks beneath. Unlike bright snow, which reflects sunlight, these darker surfaces absorb more heat, accelerating warming and speeding up glacier melt. The researchers also found that nighttime minimum temperatures are increasing faster than daytime maximum temperatures, particularly at mid-altitude locations such as Bhaderwah. Increased atmospheric moisture acts like an insulating blanket, preventing mountains from cooling efficiently after sunset. This is a critical finding, as it suggests that the warming of the Himalayas is not just a theoretical concern, but a real and present danger. The study also highlights the unique geography of Jammu and Kashmir, which makes it especially vulnerable to uneven warming. Stretching from subtropical plains to Himalayan peaks above 5,500 meters, the region spans three distinct climatic zones. The IMD data from 10 stations across Jammu and Kashmir shows that warming has remained steady over the past four decades. High-altitude regions have warmed by nearly 1 degree in just 20 years, while some mid-elevation stations are warming by around 0.3 degrees per decade. Even nighttime minimum temperatures are increasing faster than daytime maximum temperatures. This is a cause for concern, as the changing climate is already affecting the region. July 2025 recorded the three hottest days ever observed in the Kashmir Valley, placing additional stress on water resources, especially as the Himalayas serve as India's water tower. The study also warns that shrinking glaciers and declining winter snowfall could affect agriculture, horticulture, winter tourism, alpine ecosystems, forests, meadows, and biodiversity, while also threatening drinking water, irrigation, and hydropower supplies across northern India. The findings of the study are a wake-up call for stronger conservation measures and climate adaptation strategies. The growing number of vehicles entering mountain regions is adding to the problem, as tourism, whether leisure, eco-tourism, or religious tourism, has expanded rapidly without adequate planning. This has led to traffic jams and increased emissions of carbon monoxide, which is not only increasing the temperature of the Lower Himalayas but is also the most responsible factor for glacier melting in the Himalayas and the changing micro-climate. The study also points to the compounding effects of vehicular exhaust and unregulated construction on mountain slopes. The massive wave of unregulated construction on mountain slopes has led to the construction of heavy four- and five-story concrete buildings, which release massive amounts of carbon directly into the mountain air, trapping even more heat. This feedback loop acts as the final blow to the local environment, serving as the addition of the release of carbon in the air of the mountain, which remains a critical additional factor for rising the temperature in the Himalaya. The findings of the study are a warning beyond Kashmir, as faster warming at higher elevations threatens glaciers, water security, agriculture, hydropower, biodiversity, and tourism across northern India. The researchers and experts say the study underscores the need for stronger conservation measures and climate adaptation strategies before these changes become irreversible. This is a critical call to action, as the impact of climate change on the Himalayas is no longer a distant concern, but a real and present danger that requires immediate attention and action.
