Local pollutants blamed for Himalayan climate change

This article was published by SciDev.Net on June 18, 2016.

Climate change may be global, but the future of Himalayan mountain glaciers and the Tibetan plateau snowpack could come down to local air pollution, scientists say.
Since the 1960s there has been observational evidence of regional snowpack retreat and black carbon deposition over snow covers, but climate model limitations made quantifying climatic impact difficult.
Adjusted regional climate projections that recognise the impact of black carbon warming effects are crucial to local adaptation planning, Yangyang Xu, post-doctoral fellow at the US National Center for Atmospheric Research, tells SciDev.Net.

Nepalis face ‘cancer risk’ from indoor pollution

This article was published by SciDev.Net on May 4, 2016.

Nepalis who have never smoked are among those facing an increased risk of lung cancer due to common household air pollutants, says a new study.
Women and children are particularly vulnerable to long-term exposure to household air pollution, say researchers from the University of Maryland Institute for Applied Environmental Health, University of Utah School of Medicine and Nepal’s B.P. Koirala Memorial Cancer Hospital who were involved in the study.
Due to be published this month (May) in Environmental Research, the study investigated the association between exposure to household air pollutants created by burning biomass fuels — such as wood, charcoal, crop residue and dung — and lung cancer risk.
