Fossil fuels induced Black Carbon melt Himalayan snows, says study
NEW DELHI: A recent report indicates that Black Carbon emissions have raised snow surface temperatures by 4°C over the past two decades, accelerating the melting processes of Himalayan glaciers, particularly in the Eastern and Central Himalayas. Delhi-based research organisation Climate Trend study analysis examined NASA satellite data of the Himalayan glaciers from 2000-2023 to evaluate the impact of Black Carbon emissions resulting from burning biomass and fossil fuels. The study – 'Impact of Black Carbon on Himalayan Glaciers: A 23-Year Trends Analysis' shows that Black Carbon (BC) concentration in the region rose significantly from 2000 to 2019. Further, the levels see relative stabilisation between 2019 and 2023, suggesting a possible plateau in emissions or a change in atmospheric conditions. According to the report, the average snow surface temperatures in the Himalayan snow peaks have increased by more than 4°C over the last two decades, from an average of -11.27°C (2000–2009) to -7.13°C (2020–2023). The overall mean temperature increase over the 23 years was -8.57°C. Regions with higher Black Carbon deposition have higher snow surface temperatures and lower snow depth. Hence, more Black Carbon means higher surface temperature, more snow melt, and reduced snow depth. The research reveals that black carbon particles darken snow surfaces, lower their reflectivity (albedo), and make them absorb more solar radiation, which results in faster snow melt.

Eastern Himalayas show highest black carbon levels; snow loss tied to biomass burning
New Delhi: Snow surface temperatures in the Himalayan region have risen by more than 4°C over the last two decades due to increasing levels of black carbon emissions , a new study by Delhi-based research consultancy Climate Trends has found. The analysis, based on 23 years of NASA satellite data (2000–2023), reports accelerated melting in areas with higher black carbon deposits, particularly in the Eastern and Central Himalayas. According to the study titled Impact of Black Carbon on Himalayan Glaciers: A 23-Year Trends Analysis, the average snow surface temperature rose from -11.27°C (2000–2009) to -7.13°C (2020–2023). The study found that regions with higher black carbon concentrations showed greater snow melt and reduced snow depth. The research attributes the presence of black carbon to emissions from biomass combustion, fossil fuel use, and open burning in the Indo-Gangetic Plain. 'Glacier melt is accelerating, threatening freshwater resources to nearly two billion people downstream,' said Dr Palak Baliyan, lead author of the study. Black carbon reduces the reflectivity (albedo) of snow, causing it to absorb more solar radiation and melt faster. Although concentrations plateaued somewhat between 2019 and 2023, the long-term warming trend is clear. 'Black carbon acts like a heat lamp on snow,' the report stated. Speaking at the India Heat Summit 2025, Dr Farooq Azam, Senior Cryosphere Specialist, ICIMOD, cited 2022 as the worst year for glacier mass balance, with Himalayan glaciers such as Chhota Shigri in Himachal Pradesh losing up to two metres of ice. 'Since 2022, glacial mass loss is four times higher than normal. With more temperature, glaciers shrink and more heavy metals melt into river water,' he said. Dr Azam also said that black carbon from the Indo-Gangetic Plain is carried by winds and deposited on glaciers. 'This darkens the snow surface, reducing albedo, and accelerates heat absorption,' he added. Some studies estimate that the additional radiation absorbed due to darkened snow is equivalent to 14–15 volts per square kilometre. The study found a strong positive correlation between black carbon and snow surface temperature and a negative correlation with snow depth, even when controlling for temperature, indicating a direct impact of black carbon on snowpack. 'Reducing black carbon, especially from cookstoves, crop burning, and transport, can offer quick wins for climate and water security,' said Aarti Khosla, Director, Climate Trends. The report advocates targeted policy interventions in the Indo-Gangetic region to mitigate black carbon emissions. Dr Azam added that signs of climatic impact are evident in increased avalanches, shifting agricultural zones, and glacier loss, including the near disappearance of Yala Glacier in Nepal. 'In 2022 alone, glaciers experienced up to four times the normal mass loss, equivalent to 2 metres of ice from Chhota Shigri Glacier,' he said. The report concludes that cutting black carbon emissions can yield short-term regional cooling and help slow glacial retreat.

Trainer Aircraft Overturns While Landing In Madhya Pradesh, Woman Pilot Safe
Seoni: A trainer aircraft overturned while landing at Suktara airstrip in the district on Friday morning but its trainee woman pilot was safe, the police said. The aircraft flipped over due to a faulty landing, said a police official. The airstrip is 22 km from the Seoni district headquarters. The trainee woman pilot who was flying the aircraft alone did not suffer any injuries, said the official. While the airstrip is maintained by the Madhya Pradesh Public Works Department, it is used by Delhi-based Red Bird Aviation Company to run a pilot training school. District collector Sanskriti Jain said the concerned department has been asked to conduct an inquiry, after which the exact cause of the accident will become clear. Employees of the Red Bird Aviation Company emptied the fuel tank of the aircraft immediately after the incident. A major tragedy was averted as the aircraft did not catch fire during the crash-landing, said the police official. Barghat Sub Divisional Officer of Police (SDOP) Lalit Ghatre said the employees of Red Bird Aviation Company did not inform the police about the incident which took place under Kurai police station limits. They informed the Directorate General of Civil Aviation's Bhopal office which in turn alerted the police. The police then contacted the company's airstrip manager Santosh Sanodia and obtained details, Ghatre said. When contacted for his comments, Sanodia refused to speak. Meanwhile, a DGCA team will soon reach Suktara airstrip and prepare a report after an inspection, the police official said. According to preliminary information, the trainee pilot tried to land the aircraft with the front landing gear instead of the rear one, due to which the aircraft went out of control and overturned, officials said. Flights of trainee aircraft from Suktara airstrip have been stopped for the time being, they added.
