Earth is losing ice 57 pct faster today than in the mid-1990s: Study

Reuters

London, Jan 25: Earth’s ice is melting faster today than in the mid-1990s, new research suggests, as climate change nudges global temperatures ever higher.

Altogether, an estimated 28 trillion metric tons of ice have melted away from the world’s sea ice, ice sheets and glaciers since the mid-1990s.

Annually, the melt rate is now about 57 percent faster than it was three decades ago, scientists report in a study published Monday in the journal The Cryosphere.

“It was a surprise to see such a large increase in just 30 years,” said co-author Thomas Slater, a glaciologist at Leeds University in Britain.

While the situation is clear to those depending on mountain glaciers for drinking water or relying on winter sea ice to protect coastal homes from storms, the world’s ice melt has begun to grab attention far from frozen regions, Slater noted.

Aside from being captivated by the beauty of polar regions, “people do recognize that, although the ice is far away, the effects of the melting will be felt by them,” he said.

The melting of land ice – on Antarctica, Greenland and mountain glaciers – added enough water to the ocean during the three-decade time period to raise the average global sea level by 3.5 centimeters. Ice loss from mountain glaciers accounted for 22 percent of the annual ice loss totals, which is noteworthy considering it accounts for only about 1 percent of all land ice atop land, Slater said.

Across the Arctic, sea ice is also shrinking to new summertime lows. Last year saw the second-lowest sea ice extent in more than 40 years of satellite monitoring. As sea ice vanishes, it exposes dark water which absorbs solar radiation, rather than reflecting it back out of the atmosphere. This phenomenon, known as Arctic amplification, boosts regional temperatures even further.

The global atmospheric temperature has risen by about 1.1 degrees Celsius since pre-industrial times. But in the Arctic, the warming rate has been more than twice the global average in the last 30 years.

Using 1994–2017 satellite data, site measurements and some computer simulations, the team of British scientists calculated that the world was losing an average of 0.8 trillion metric tons of ice per year in the 1990s, but about 1.2 trillion metric tons annually in recent years.

Calculating even an estimated ice loss total from the world’s glaciers, ice sheets and polar seas is “a really interesting approach, and one that’s actually quite needed,” said geologist Gabriel Wolken with the Alaska Division of Geological and Geophysical Surveys. Wolken was a co author on the 2020 Arctic Report Card released in December, but was not involved with the new study.

In Alaska, people are “keenly aware” of glacial ice loss, Wolken said. “You can see the changes with the human eye.”

Research scientist Julienne Stroeve of the National Snow and Ice Data Center in Boulder, Colorado noted the study had not included snow cover over land, “which also has a strong albedo feedback”, referring to a measure of how reflective a surface is.

The research also did not consider river or lake ice or permafrost, except to say that “these elements of the cryosphere have also experienced considerable change over recent decades.”

World’s Most Vaccinated Nation Activates Curbs as Cases Rise

(Asian News Hub) – Seychelles, which has fully vaccinated more of its population against Covid-19 than any other country, has closed schools and canceled sporting activities for two weeks as infections surge.

The measures, which include bans on the intermingling of households and the early closure of bars, come even as the country has fully vaccinated more than 60% of its adult population with two doses of coronavirus vaccines. The curbs are similar to those last imposed at the end of 2020.

“Despite of all the exceptional efforts we are making, the Covid-19 situation in our country is critical right now with many daily cases reported last week,” Peggy Vidot, the nation’s health minister, said at a press conference Tuesday.

The Indian Ocean archipelago, which has a population of about 98,000, is dependent on tourism for much of its foreign exchange and acted quickly to begin vaccinations in January using a donation of Chinese vaccines from the United Arab Emirates. It has procured other vaccines since.

By April 12, 59% of the doses administered were Sinopharm vaccines and the rest were Covishield, a version of AstraZeneca Plc’s shot made under license in India.

To date 62.2% of its eligible population is fully vaccinated, according to the Bloomberg Vaccine Tracker. That compares with 55.9% for Israel, the next most vaccinated nation.

Officials at the press conference gave little detail on what could be behind the infection surge other than to say people were taking fewer precautions against the virus than before and the surge may be due to celebrations after Easter.

The number of active cases in the nation rose to 1,068 on May 3 from 612 on April 28, according to health ministry announcements.

Devastating impact of the pandemic on media, deplorable situation in India: PEC

(Asian News Hub) – The Covid-19 pandemic had a devastating impact on the media, the Switzerland based media rights and safety body Press Emblem Campaign (PEC) lamented on Friday in preparation for World Press Freedom Day on 3 May.

Human cost of the pandemic is particularly high where over one thousand journalists have lost their lives due to novel corona virus aggravated ailments. India recently lost over 50 journalists in 2 weeks (3.5 per day).

Human cost of the pandemic is particularly high where over one thousand journalists have lost their lives due to novel corona virus aggravated ailments. Journalists are engaged in a profession which is particularly exposed to the virus, as many have been forced to continue working in contact with the population. Until 29 April 2021, since March 2020, within 14 months, the PEC (www.pressemblem.ch/) has counted more than 1,200 journalists who died from complications related to Covid-19 in 75 countries.

“This is an unprecedented slaughter and a great loss for the profession,” said PEC secretary-general Blaise Lempen adding, “On the occasion of World Press Freedom Day, we call for honoring eminent colleagues of all ages who have not survived the pandemic.” He appeals to all concerned governments to take action to help the media most affected and support the families of the victims on this auspicious occasion.

PEC also considers there is a need to distribute vaccines equally all over the world, to stop spread of the virus and its new strains in developing countries.

Vaccine production is limited and it is available for the wealthiest countries, preventing access to journalists in South America and South Asia. As long as this situation continues, deaths will keep on increasing, it added.

The rate of deceased journalists accelerated further in April with the deaths of 126 journalists in one month or four media-victims per day. Since the pandemic broke out in March 2020, four countries have been particularly affected with more than one hundred journo-casualties each including Brazil (more than 183 media corona-casualties), Peru (140 dead), India (122) and Mexico (106).

There is nevertheless a positive note that the number of journalists’ deaths slowed sharply in Europe and North America, thanks to effective protection measures and the progress of vaccination. By region, Latin America tops the list with more than half of the victims, 673 in 20 countries. Asia follows with 256 in 18 countries, then Europe with 175 in 19 countries.

Africa comes next with 56 dead in 16 countries, ahead of North America with 47 in 2 countries.

India recently lost half a century journalists within a fortnight to corona-complications, said Nava Thakuria, PEC’s country representative adding that the populous country might have lost more journalists than documented, as many media outlets in India prefer to tone done the corona casualties among their journo-colleagues. India’s neighbour Bangladesh recorded 52 journo-victims to Covid-19 followed by Pakistan (26 dead), Afghanistan (9) and Nepal (7). Other tiny neighbours namely Bhutan, Sri Lanka, Maldives, Myanmar etc have not reported a single corona media casualty.

The robust Indian media fraternity has lately lost Rohit Sardana, Nilakshi Bhattacharyya, Aiyushman Dutta, Bhanu Prakash Rath, Manas Ranjan Jaipuria, Amjad Badshah, Sridhar Dharmasanam, Raju Mishra, Sadanand Shinde, Kakoli Bhattacharya, Kondra Srinivas Goud, Sammi Reddy, Akash Saxena, Khwaja Mujahiduddin, Anil Basnoi, Venga Reddy, Madiraju Harikrishna Giri, Syed Shabaz, etc to the corona-pandemic. Good bye friends and rest in absolute peace around the unseen world.

India rapidly losing scribes to Covid-19, global tally reaches 1175

(Asian News Hub) – India is fast losing working journalists to Covid-19 and crossed 100 mark, where as the global tally hit 1,175. The country lately starts losing three journalists every day.

Brazil continues to be the worst affected country with 181 media corona-casualties followed by Peru (140) and Mexico (106), stated the Switzerland based media rights & safety body Press Emblem Campaign (PEC).

India, which witnessed the death of nine journalists due to novel corona virus infection aggravated ailments in the last three days, is just behind of Mexico with 101 casualties since the pandemic broke out in March 2020. The nation with a billion plus populace comes far ahead of Italy (52 dead), Bangladesh (51), USA (47), Colombia (47), Ecuador (46), United Kingdom (28), Dominican Republic (27), Pakistan (25), Turkey (22), Iran (21), etc.

Expressing apprehensions that the situation may worsen for the safety of journalists on the ground due to the corona-pandemic, Blaise Lempen, general secretary of PRESS EMBLEM CAMPAIGN (PEC), advocates for adequate compensations to the victim families. He also emphasized on early vaccinations to media workers so that they can perform their duties as corona warriors after the doctors, nurses, sanitation workers, etc without endangering their lives.

Even after the launch of a massive corona-vaccination program covering around 13 million Indian citizens India till now in the backdrop of around three million reported infections every day mounting its cumulative Covid-19 cases to over 16 million (total casualty crosses 190,000).

Reported names of recent corona-victims include Shailesh Raval (Gujarat), Sopan Bongane, Ashok Tupe, Motichand Bedmutha (Maharashtra), P Tataiah, Chandrashekar Naidu, Srinivasa Rao (Andhra Pradesh), Ashish Yechury, Chanchal Pal Chauhan (New Delhi), Chinta Naga Raju, Ramachandra Rao (Telangana), Govind Behera, Manoj Kumar Sahu, Karunakar Sahu, Naresh Behera (Odisha), Jodu Chutia (Assam), etc.

“India has the probability to increase the number of media corona-victims as a number of States went on under-reporting about the actual figures because of various reasons,” commented PEC’s country representative Nava Thakuria adding, in many cases even the established media houses had not reported about their own corona-positive cases to avoid unwanted interferences from the authority under the health protocols.
