  • A recent study stated that Levels of black carbon-ultra-fine particles of carbon in the Himalayas have been rising.
  • Eastern Himalaya records warmest snow surfaces, followed by the central and western Himalayas.
  • The average snow-surface temperature has increased from -11.27°C from 2000–2009 to -7.13°C during 2020–2023.
  • Black carbon generally absorbs sunlight and if it settles on the surface can thus heat the ground.
  • The major generators of the black carbon include biomass combustion, fossil fuel use, and open burning, particularly in the Indo-Gangetic plain, which acts as a hotspot for emissions.
