Arctic winter sea ice in 2021 joint seventh-lowest on record, finds NASA

Published

on

Sea ice in the Arctic has reached its maximum extent for 2021 — tying with 2007’s as the seventh-smallest extent of winter sea ice. This may mean that the Arctic is losing more ice than it can recover.

The ice peaked at 14.77 million square kilometres (km2) on March 21, according to scientists at the National Aeronautics and Space Administration (NASA)-supported National Snow and Ice Data Center (NSIDC).

The NSIDC has termed the development as “uneventful maximum”. It, however, noted it followed an “exceptional” year for sea ice: Arctic’s summer minimum in September 2020 was the second-lowest on record.

This year’s maximum was 870,000 km2 below the 1981-2010 average maximum and 360,000 km2 above the lowest maximum recorded in 2017, NSIDC noted.

The ice extent in the Arctic changes throughout the year: It grows during the winter before reaching its peak in February or March. It then melts throughout the spring and summer towards its annual minimum, which is typically in September.

Carbon Brief quoted Ted Scambos, senior research scientist at NSIDC, as saying:

“The sea ice maximum in 2021 is not close to a record, but still quite low compared to any year prior to 2000.”

The low ice extent, according to NSIDC, was because of the positive phase of the phenomenon called Arctic Oscillation. During this phase, a ring of strong winds circulating around the North Pole acts to confine colder air across polar regions.

This pattern transported ice from the Siberian coast, across the pole and out of the Arctic Ocean, leaving thinner ice along the Siberian coast which was more prone to melting.

According to NSIDC:

From 13 October into early November, the daily sea ice extent was the lowest for that day in the satellite record. The low sea ice extent left vast expanses of open water across the Arctic throughout November, which lost heat to the atmosphere and caused hotspots to form near the surface of the ocean.

Fuel price hikes trigger transport disruptions and calls for fare increases

Published

on

The latest fuel price increases have sparked widespread concern among transport operators and raised questions about the government’s supportive measures. Cabinet Spokesman and Minister Dr Nalinda Jayathissa told a media briefing yesterday that the government was incurring a monthly loss of Rs. 20 billion by maintaining subsidies on fuel. According to the Minister, the state loses Rs. 100 per litre of diesel and Rs. 20 per litre of petrol under the current pricing system, a burden that the Treasury continues to absorb as part of a “supportive mechanism.”

The Ceylon Petroleum Corporation (CPC) revised fuel prices from midnight on March 21, raising the price of a litre of Lanka Auto Diesel by Rs. 79 to Rs. 382, Super Diesel by Rs. 90 to Rs. 443, Octane 95 petrol by Rs. 90 to Rs. 455, and Octane 92 petrol by Rs. 81 to Rs. 398. Lanka Kerosene was increased by Rs. 60,bringing the price to Rs. 255 per litre. Other suppliers, including Sinopec and Lanka IOC, also implemented similar hikes, with Sinopec’s Super Diesel rising sharply by Rs. 219 to Rs. 572 per litre.

The surge in fuel prices has had an immediate impact on public transport. The Chairman of the Lanka Private Bus Owners’ Association, Gamunu Wijerathne, told The Island that 90% of private buses were off the road yesterday (22). He called for a 15% increase in bus fares, raising the minimum fare from Rs. 27 to Rs. 35, warning that services could be suspended if fare adjustments are not approved.

Three-wheeler operators have also pressed for immediate fare revisions. L. Rohana Perera, General Secretary of the National Joint Three-Wheeler and Industrialists’ Association, said the rising fuel costs have made it difficult for drivers to continue operating. The Association has proposed a Rs. 20 increase for the first kilometre fare for all meter-operated three-wheelers and plans to present its concerns to the Presidential Secretariat.

Fuel price monitoring has also intensified amid concerns over potential smuggling. A senior police officer told The Island that intelligence units have been deployed near fuel stations to prevent hoarding. The police suspect that certain fuel station employees and owners could be facilitating stockpiling.

Political leaders have warned that the hikes will ripple across the economy. SJB MP S.M. Marikkar said transport cost increases will drive up the prices of essential goods such as rice and fish, leaving consumers struggling under rising costs.

Import and export container transportation charges will be increased by 20% from midnight yesterday (22) due to the recent fuel price hike, according to the Container Transport Vehicle Owners’ Association.

The latest increases follow two rounds of price hikes since March 9, driven by surging global oil prices amid the Middle East conflict. Since then, Lanka Petrol 92 Octane has risen by Rs. 105 to Rs. 398, Petrol 95 Octane by Rs. 115 to Rs. 455, Auto Diesel by Rs. 101 to Rs. 382, and Super Diesel by Rs. 114 to Rs. 443 representing an overall increase of around 35% across key fuel categories.

Prof. Peiris honoured by International Institute of Rehabilitation

Published

Felicitating Prof. Peiris at the event were Senior Lecturer Ravindra Samarawickrama, Chairman of the International Organisation for Crime Prevention and Rehabilitation, Director Nilantha Kotikawatte, and Senior Lecturer Udaya Kumara Amarasingha, Head of the Department of Criminology and Criminal Justice at the University of Sri Jayewardenepura

At the award presentation ceremony of the International Rehabilitation Institute last week, Professor G.L. Peiris, as Chief Guest, in his keynote address, dealt with the special relevance of rehabilitation at this time. The traditional criminal law makes provision for punishment after a crime has been committed, and punishment usually takes the form of a prison sentence. It is even more important, however, to explore practical means of prevention and also to have recourse to a custodial sentence as a last resort rather than as the typical response.

The modern approach is that punishment is seen not as retributive but as a means of rehabilitating the offender in society. Prison sentences, bringing a first offender into the prison environment and association with habitual offenders, carries the risk of recidivism, the available statistics indicating the likelihood of return to prison on repeated occasions.

He placed emphasis on the importance of informed social attitudes to ensure that an offender does not carry a permanent stigma, reducing his opportunities for employment and acceptance in society. The importance of religious instruction in early childhood, and the close connection between temple and village, was stressed.

Professor Peiris was honoured with an award of appreciation by academic colleagues.
