South Asian black carbon aerosols increase glacial mass loss over Tibetan plateau: Study

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.

Bribery chief says don’t abuse the term ‘political victimization”

Published

on

Director General of the Commission to Investigate Allegations of Bribery or Corruption, Ranga Dissanayake, says that the abuse of the term “political victimization” will no longer be tolerated, and those who misuse the term will face strict legal action.

Dissanayake told a media conference held at the CIABOC auditorium: “There is a widespread perception that the law is not effectively enforced in this country. This perception has arisen because, as the President said on Anti-Corruption Day, small fish are caught while the big fish escape. This perception exists for several reasons, including delays in the Bribery or Corruption Investigation Commission’s processes. At times, the public is unaware of the injustices that occur within the Commission.”

Addressing politicians who make public statements, he requested, “I sincerely ask political leaders who issue statements to the media to kindly refer to the Anti-Corruption Act No. 9 of 2023 that you have endorsed. Please refrain from making certain statements without a proper understanding. This law has been enacted independently of any prior connections or influences. I have been in this position since the beginning of this year. The Bribery Commission currently has 31 legal officers, and there is no capacity to recruit additional staff at this time.”

He also highlighted the significant challenges faced by the Commission, revealing that approximately 4,000 unresolved case files remain due to limited resources and personnel. “No matter what we do, people will still ask, ‘How many criminals have been caught?’ This situation is the result of limited resources and staff,” he said.

Dissanayake also said: “If anyone is going to claim political victimization, let them find evidence and prove it. Otherwise, the powers granted by this law will be used against those who make false claims.”

SC dismisses 50 petitions, orders enforcing CA ruling on 37 others

Rejection of LG nominations

The Supreme Court on Friday dismissed over 50 petitions challenging the rejection of nomination papers for the upcoming 2025 Local Government Elections.

A total of 53 writ applications and six Fundamental Rights (FR) petitions, filed by political parties and independent groups, were dismissed.

This ruling follows a recent decision by the Court of Appeal, which had ordered the acceptance of 37 nominations that were initially rejected. In a significant move, the Supreme Court Friday instructed the relevant returning officers to accept the previously rejected nominations, aligning with the Court of Appeal’s verdict.

The petitions had been filed by recognized political parties and independent groups who challenged the rejection of their nominations. The reasons for the rejection included issues such as failure to submit certified copies of birth certificates of candidates, failure to submit an official oath, and submitting only photocopies of birth certificates instead of the required certified versions.

Singer Toastmasters Club Officers 2024-2025 with District 82 Members

Celebrating a Century of Soft Skills Development with Toastmasters International

The beginning of a new Toastmasters year is always an exciting occasion for clubs worldwide, and this year, the celebration is even more special as Toastmasters International marks its 100th year of developing soft skills in public speaking, effective communication, and leadership.

At the onset of the Toastmasters year on 1st July 2024, with the vision “United Roots, Shared Bloom,” the gavel was passed to TM Chanuka Obeysekera, the 14th President of Singer Sri Lanka Toastmasters Club. This marks another chapter in the club’s commitment to fostering personal development and growth in its members. On 19th September 2024, the club saw a momentous occasion with the installation of new Club Officers and the induction of nine new members.

TM Udani Mendis, a new member of the club, shared her experience: “Toastmasters has transformed my journey into one of self-discovery and empowerment. Each meeting pushes me to overcome my fears and celebrate my progress as a communicator. Through this experience, I’ve grown into a confident leader, ready to inspire others.”

The club provides a safe space where members offer constructive, positive feedback, empowering each other to develop without fear of judgment. The focus is not on perfection, but on constant growth, with each member taking steps towards realizing their potential. The learning experience at the club goes far beyond just delivering speeches. While public speaking is a key focus, the networking opportunities and personal connections made are an integral part of the club’s value. This year, members of the club have also taken up leadership roles within District 82 and Division C. TM Rosanne Ranasinghe was appointed as Division Director, TM Rolinka Perera as Toastmaster Learning Chair of Division C, and TM Viraj Chathuranga as Finance Manager of Division C.

The energy, enthusiasm, and camaraderie shared among members is palpable. The collective commitment to creativity and excellence continues to push the boundaries of what a standard club meeting can achieve. Toastmasters is about both individual achievement and the shared growth of all members, creating a community where bonds are built, experiences are exchanged, and each person is empowered to achieve their full potential.

The club remains committed to its mission – not just to learn, but to teach, inspire, and help others realize their dreams.
