Changing Snowfall Patterns in Himachal Pradesh Raise Climate Concerns

In Himachal Pradesh, there has been a decline in snow cover over the years, accompanied by a noticeable shift in snowfall patterns. Rather than occurring primarily during winter months, snowfall now extends into early summer months. This phenomenon raises concerns about climate variability in the ecologically fragile Himalayan region.

The reduction in snow cover during peak winter months (December and January) is particularly worrisome. It could impact water availability during the summer, as the snow accumulated during these peak winter periods sustains river basins and enhances their discharge reliability. Environmentalists and scientists are alarmed by this shift, which has been observed over the past decade. Snowfall is gradually decreasing during peak winter and shifting toward late winter months or even early summer months. The reasons behind this change are multifaceted, and addressing depleting snow cover and alterations in snowfall patterns should be a priority for all.

Nestled in the ecologically fragile Himalayas, Himachal faces not only diminishing snow cover but also a change in snowfall occurrence. Researchers from the Centre on Climate Change of Himachal Pradesh Council for Science Technology-Environment (HIMCOSTE) report a 12.72% reduction in snow-covered area during the 2023-24 winter compared to the previous year. While early winter months experienced less snow cover, late winter and early summer months saw an increase. This shift in snowfall patterns has implications for hydro-power, water sources, and ecosystems in the region. Environmentalists and scientists emphasize the need to promptly address this trend to safeguard vital resources and infrastructure.
