South Asian black carbon aerosols increase glacial mass loss over Tibetan plateau: Study
=The South Asia region adjacent to the Tibetan Plateau has among the highest levels of black carbon emission in the world.
January 02, 2023 (pti): Black carbon aerosols have indirectly affected the mass gain of the Tibetan Plateau glaciers by changing long-range water vapour transport from the South Asian monsoon region, a study has found.
The South Asia region adjacent to the Tibetan Plateau has among the highest levels of black carbon emission in the world, the researchers said.Black carbon aerosols are produced by the incomplete combustion of fossil fuels and biomass, and are characterised by strong light absorption.
Many studies have emphasised black carbon aerosols from South Asia can be transported across the Himalayas to the inland region of the Tibetan Plateau.Researchers noted that black carbon deposition in snow reduces the albedo of surfaces — a measure of how much of Sun's radiations are reflected — which may accelerate the melting of glaciers and snow cover, thus changing the hydrological process and water resources in the region.
The study, published in Nature Communications, found that since the 21st century, South Asian black carbon aerosols have indirectly affected the mass gain of the Tibetan Plateau glaciers by changing long-range water vapour transport from the South Asian monsoon region.
Black carbon aerosols in South Asia heat up the middle and upper atmosphere, thus increasing the North–South temperature gradient," said Professor KANG Shichang from Chinese Academy of Sciences (CAS).
Accordingly, the convective activity in South Asia is enhanced, which causes convergence of water vapour in South Asia. Meanwhile, black carbon also increases the number of cloud condensation nuclei in the atmosphere," Shichang said.
These changes in meteorological conditions caused by black carbon aerosols make more water vapour form precipitation in South Asia, and the northward transport to the Tibetan Plateau was weakened, the researchers said.As a result, precipitation in the central and the southern Tibetan Plateau decreases during the monsoon, especially in the southern Tibetan Plateau, they said.
The decrease in precipitation further leads to a decrease of mass gain of glaciers.From 2007 to 2016, the reduced mass gain by precipitation decrease accounted for 11% of the average glacier mass loss on the Tibetan Plateau and 22.1% in the Himalayas.The transboundary transport and deposition of black carbon aerosols from South Asia accelerate glacier ablation over the Tibetan Plateau.Meanwhile, the reduction of summer precipitation over the Tibetan Plateau will reduce the mass gain of plateau glaciers, which will increase the amount of glacier mass deficit, Shichang added.

A Policy is being formulated to ensure Child Protection in the use of Technology — Prime Minister
Prime Minister Dr. Harini Amarasuriya stated that a policy is currently being formulated to ensure child protection in the use of technology.
The Prime Minister made this statement on Thursday (08) in Kandy while briefing the Most Venerable Mahanayake Theros of the Asgiriya and Malwathu Chapters on the issue that has arisen regarding the Grade 6 English module. Thereafter, printed copies of all modules were presented to the Mahanayake Theros.
Earlier on Thursday (08), the Prime Minister visited the Malwathu Viharaya in Kandy and met the Most Venerable Thibbatuwawe Sri Siddhartha Sumangala Nayaka Thero, the Mahanayake of the Malwathu Chapter, where she explained the error that had occurred in the first print run of the English module for Grade 6 .
The Mahanayake Theros emphasized that education is a sensitive subject and that such matters should be handled with greater sensitivity and proper oversight. They further advised that a formal investigation should be conducted and that education reforms should be carried forward in a systematic manner.
Subsequently, the Prime Minister visited the Asgiriya Maha Viharaya and met the Most Venerable Warakagoda Sri Gnanarathana Mahanayaka Thero of the Asgiriya Chapter, where she clarified the error related to the English module.
The Mahanayake Thero noted that education reforms are a timely necessity and should be implemented with due oversight and careful review and also pointed out that there are broader issues in Sri Lanka regarding the use of technology, which are evident in the manner in which modern tools such as AI technologies are being used on social media.
Clarifying the issue Prime Minister Dr. Harini Amarasuriya further stated,
“We have appointed a committee to look into this issue, and based on the recommendations of the National Institute of Education (NIE), steps were taken to remove the relevant lesson. In addition, all printed copies of the relevant module have been stamped, and no module has been distributed to schoolchildren. A formal investigation into this matter has been initiated by the Ministry, and a complaint has also been lodged with the Criminal Investigation Department.
At the same time, we are in the process of formulating a policy on child protection in the use of technology”.
Thereafter, addressing the media and responding to the’ questions raised by journalists, the Prime Minister stated:
“The Opposition is attempting to use this national task for their own political advantage. However, many in society have expressed their views on the issues that have arisen in a positive manner, with the objective of identifying and correcting mistakes. The government has decided to move forward with education reforms by recognizing the error that have occurred and rectifying them. We will take the no-confidence motion brought by the Opposition as an opportunity to further advance dialogue on education reforms”
The occasion was graced by the Most Venerable Anunayaka Thero of the Asgiriya Chapter, Venerable Narampanawe Ananda Nayaka Thero; Deputy Registrar of the Asgiriya Chapter, Venerable Muruddeniye Dhammarakkhita Thero; Deputy Registrar of the Malwathu Chapter, Venerable Mahawela Rathanapala Thero; Members of Parliament Thushari Jayasinghe and Thanura Dissanayake; Mayor of Kandy Chandrasiri Wijenayake; Secretary to the Ministry of Education Nalaka Kaluwewa; and Secretary to the Ceylon Teachers’ Union in Central Province D. D. Wimalaweera.

The deep depression to the South-east of Sri Lanka is likely to intensify in to a cyclonic storm during the next 24 hours
A RED warning for a deep depression to the South-east of Sri Lanka has been issued at 01.00 a.m. on 09 January 2026 for the period until 01.00 a.m. 10 January 2026 by the Natural Hazards Early Warning Centre, of the Department of Meteorology.
The deep depression in the Bay of Bengal to the southeast of Sri Lanka (At 01:00 a.m. on Jan 9th, 2026 located about 200 km East of Pottuvil) is very likely to intensify further and move west-northwestwards towards the coast of Sri Lanka between Pottuvil and Trincomalee in the evening today (9th January 2026.) The system is likely to intensify in to a cyclonic storm
during the next 24 hours.
Hence, showery, and windy condition over the island, particularly in the Northern, North-Central, Eastern, Uva and Central provinces is expected to enhance.
