Cold comfort: The sun is cooling; doesn’t mean there will be no global warming
A new 11-year-cycle of the Sun has begun. Scientists believe the Sun was at its weakest in 2019 in the last 100 years or so — known as the solar minimum — and 2020 marks the beginning of the 25th cycle. But the odd thing is that solar activity, measured by the number of Sun spots at any given time, is pretty low even in 2020.
Sun spots are areas of strong magnetic forces on the surface of the Sun — sometimes as large as planets — that appear as darker spots because they are cooler.
The Sun had no Sun spots for around 71 per cent in 2020 through September 21, 2020, compared to 77 per cent in 2019, according to the United States National Oceanic and Atmospheric Administration’s (NOAA) Space Environment Centre. In May this year, it was as high as 78 per cent, sparking fears of a Little Ice Age.
Scientists say the Sun may be going through a long period of decreased activity known as the Modern Grand Solar Minimum from 2020 to 2053. The last time such an event occurred was during the Maunder Minimum — from 1645 AD to 1710 AD, which was part of what is now known as the Little Ice Age — when Earth went through a series of elongated cold periods during the medieval centuries.
The alarm went off when a study predicted that the surface temperatures on Earth will go down noticeably during the Modern Grand Solar Minimum due to a 70 per cent reduction in solar magnetic activity.
The research paper, by Valentina Zarkhova of Northumbria University, the UK, was published in Temperature on August 4, 2020. To arrive at her conclusion, Zarkhova studied the complex magnetic activity in the interior of the Sun and how this impacts its total energy output measured as solar irradiance.
Variations in solar irradiance lead to heating of the upper layer of the Earth’s atmosphere and influences the transport of solar energy towards the planet’s surface.
Zarkhova studied the magnetic activity through the solar background magnetic field which occurs in the form of two magnetic waves inside the Sun.
When Zarkhova combined these two waves for solar cycles 21-26, she found that the Sun’s magnitude is going down in cycles 24-25 and becoming almost zero in cycle 26. She also found multiple grand solar minima events, including the current event from 2020-2053.
During the Maunder Minimum in the middle ages, the solar irradiance went down by 0.22 per cent or 3 watt per square metre (W/sqm) in 1710 AD when the period ended.
This brought down the temperatures in the Northern Hemisphere, especially in Europe, by 1-1.5 degree Celsius and led to frozen rivers, long cold winters and cold summers. This happened because of the complex impacts of decreased solar activity on the abundance of ozone in the Earth’s atmosphere and on climatic cycles such as the North Atlantic Oscillation (NAO).
The NAO, the balance between a permanent low-pressure system near Greenland and a permanent high-pressure system to its south, was in a negative phase during the Maunder Minimum. This plunged Europe into colder-than usual temperatures. – Down to Earth
The U.S. Embassy in Colombo welcomed the U.S. Sports Envoys to Sri Lanka, former National Basketball Association (NBA) and Women’s National Basketball Association (WNBA) players Stephen Howard and Astou Ndiaye, from June 8 through 14.
The Public Diplomacy section of the U.S. Embassy said that it would launch a weeklong basketball program intended to harness the unifying power of sports, made possible through collaboration with Foundation of Goodness and IImpact Hoop Lab.
While in Sri Lanka, Howard and Ndiaye, both retired professional basketball players, will conduct a weeklong program, Hoops for Hope: Bridging Borders through Basketball. The Sports Envoys will lead basketball clinics and exhibition matches and engage in leadership sessions in Colombo and Southern Province for youth aged 14-18 from Northern, Uva, Eastern and Western Provinces, offering skills and leadership training both on and off the court. The U.S. Envoys will also share their expertise with the Sri Lanka Basketball Federation, national coaches, and players, furthering the development of basketball in the country. Beyond the clinics, they will collaborate with Sri Lankan schoolchildren to take part in a community service project in the Colombo area.
“We are so proud to welcome Stephen and Astou as our Sports Envoys to Sri Lanka, to build on the strong people-to-people connections between the United States and Sri Lanka,” said U.S. Ambassador Julie Chung. “The lessons that will be shared by our Sports Envoys – communication, teamwork, resilience, inclusion, and conflict resolution – are essential for leadership development, community building, equality, and peace. The U.S. Sports Envoy program is a testament to our belief that sports can be a powerful tool in promoting peace and unity.”
SJB Colombo District MP Mujibur Rahuman in parliament demanded to know from the government the reasons for CEB suspending the leave of all its employees until further notice from Thursday.
MP Rahuman said that the CEB has got an acting General Manager anew and the latter yesterday morning issued a circular suspending leave of all CEB employees with immediate effect until further notice.
“We demand that Minister Kanchana Wijesekera should explain this to the House. This circular was issued while this debate on the new Electricity Amendment Bill was pending. There are many who oppose this Bill. The Minister must tell parliament the reason for the urge to cancel the leave of CEB employees,” the MP said.However, Speaker Mahinda Yapa Abeywardena prevented Minister Wijesekera responding to the query and said that the matter raised by MP Rahuman was not relevant.
The Chartered Institute of Personnel Management (CIPM) successfully concluded the 8th Annual CIPM Symposium, which took place on 31st May 2024. Themed “Nurturing the Human Element—Redefining HRM in a Rapidly Changing World,” the symposium underscored the pivotal role of human resource management (HRM) in today’s dynamic global landscape. Since its inception in 1959, CIPM has been dedicated to advancing the HR profession through education, professional development, and advocacy, solidifying its position as Sri Lanka’s leading professional body for HRM.
Ken Vijayakumar, the President of the CIPM, graced the occasion as the chief guest. The symposium commenced with the welcome address by the Chairperson, Prof. Arosha Adikaram, followed by the Web Launch of the Symposium Proceedings and Abstract Book by the CIPM President. The event featured distinguished addresses, including a speech by Chief Guest Ken Vijayakumar, President of CIPM, and an address by Guest of Honor Shakthi Ranatunga, Chief Operating Officer of MAS Holdings Pvt. Ltd., Sri Lanka.
The symposium also featured an inspiring keynote address by Prof. Mario Fernando, Professor of Management and Director of the Centre for Cross Cultural Management (CCCM) at the University of Wollongong, Australia.
Vote of Thanks of the inauguration session was delivered by Dr. Dillanjani Weeratunga, Symposium Co-chair.
The symposium served as a comprehensive platform for researchers to present their findings across a wide range of critical topics in HRM. These included Cultural Diversity and Inclusion, Talent Development and Retention, Ethical Leadership and Corporate Social Responsibility, Adapting to Technological Advancements, Mental Health and Well-being at Work, Global Workforce Challenges, Employee Empowerment, and Reskilling and Upskilling.
The plenary session was led by Prof. Wasantha Rajapakse. Certificates were awarded to the best paper presenters during the valedictory session, followed by a vote of thanks delivered by Kamani Perera, Manager of Research and Development.
The annual symposium of CIPM was a truly inclusive event, attracting a diverse audience that spanned undergraduates, graduates, working professionals, research scholars and lecturers. This widespread interest highlights the symposium’s significance in the field of HRM, offering a unique opportunity for everyone to network and learn from scholarly brains.The CIPM International Research Symposium was sponsored by Hambantota International Port, Sri Lanka Institute of Information Technology (SLIIT), E B Creasy & Co. PLC, and Print Xcel Company.
