The heat wave that smashed high temperature records in five European countries a week ago is now over Greenland, accelerating the melting of the island’s ice sheet and causing massive ice loss in the Arctic.
Greenland, the world’s largest island, is a semi-autonomous Danish territory between the Atlantic and Arctic oceans that has 82% of its surface covered in ice.
The area of the Greenland ice sheet that is showing indications of melt has been growing daily, and hit a record 56.5% for this year on Wednesday, said Ruth Mottram, a climate scientist with the Danish Meteorological Institute. She says that’s expected to expand and peak on Thursday before cooler temperatures slow the pace of the melt.
More than 10 billion tons (11 billion U.S. tons) of ice was lost to the oceans by surface melt on Wednesday alone, creating a net mass ice loss of some 197 billion tons (217 billion U.S. tons) from Greenland in July, she said.
”It looks like the peak will be today. But the long-term forecast is for continuing warm and sunny weather in Greenland, so that means the amount of the ice loss will continue,” she said Thursday in a telephone interview from Copenhagen.
The scope of Wednesday’s ice melt is a number difficult to grasp. To understand just how much ice is being lost, a mere 1 billion tons — or 1 gigaton — of ice loss is equivalent to about 400,000 Olympic-sized swimming pools, the Danish Meteorological Institute said. And 100 billion tons (110 billion U.S. tons) corresponds to a 0.28 mm (0.01 inch) rise in global sea levels.
Mottram said since June 1 — roughly the start of the ice-loss season — the Greenland ice sheet has lost 240 gigatons (240 billion metric tons) this year. That compares with 290 gigatons lost overall in the 2012 melt season, which usually goes through the end of August.
A June 2019 study by scientists in the U.S. and Denmark said melting ice in Greenland alone will add between 5 and 33 centimeters (2 to 13 inches) to rising global sea levels by the year 2100. If all the ice in Greenland melted — which would take centuries — the world’s oceans would rise by 7.2 meters (23 feet, 7 inches), the study found.
The current melting has been brought on by the arrival of the same warm air from North Africa and Spain that melted European cities and towns last week, setting national temperature records in Belgium, Germany, Luxembourg, the Netherlands and Britain.
In Russia, meanwhile, forest fires caused by hot, dry weather and spread by high winds are raging over nearly 30,000 square kilometers (11,580 sq. miles) of territory in Siberia and the Russian Far East, an area the size of Belgium. The smoke from these fires, some of them in Arctic territory, is so heavy it can easily be seen in satellite photos and is causing air quality problems in Russia’s third-largest city, Novosibirsk. Protesters in Moscow on Thursday were demanding that the government do more to fight the blazes.
Greenland has also been battling a slew of Arctic wildfires, something that Mottram said was uncommon in the past.
In Greenland, the melt area this year is the second-biggest in terms of ice area affected, behind more than 90% in 2012, said Mark Serreze, director of the Snow and Ice Data Center in Boulder, Colorado, which monitors ice sheets globally. Records go back to 1981.
A lot of what melts can later refreeze onto the ice sheet, but because of the conditions ahead of this summer’s heat wave, the amount of ice lost for good this year might be the same as in 2012 or more, according to scientists. They noted a long build up to this summer’s ice melt — including higher overall temperatures for months — and a very dry winter with little snow in many places, which would normally offer some protection to glacier ice.
”This is certainly a weather event superimposed on this overall trend of warmer conditions” that have increasingly melted Greenland ice over the long term, Serreze said.
Compounding the melt, the Greenland ice sheet started out behind this year because of the low ice and snow accumulation, said Snow and Ice Data Center scientist Twila Moon.
With man-made climate change, “there’s a potential for these kind of rates to become more common 50 years from now,” Moon said.

Heat waves have always occurred, but Mike Sparrow, a spokesman for the U.N. World Meteorological Organization, noted that as global temperatures have risen, extreme heat waves are now occurring at least 10 times more frequently than a century ago. This year, the world saw its hottest month of June ever.
”These kind of heat waves are weather events and can occur naturally but studies have shown that both the frequency and intensity of these heat waves have increased due to global warming,” Sparrow said in a telephone interview from Geneva.
He noted that sea ice spread in the Arctic and Antarctic are both currently at record lows.
”When people talk about the average global temperature increasing by a little more than 1 degree [Celsius], that’s not a huge amount to notice if you’re sitting in Hamburg or London, but that’s a global average and it’s much greater in the polar regions,” he said.
Even though temperatures will be going down in Greenland by the end of this week, the ice melt is not likely to stop anytime soon, Mottram said.
”Over the last couple of days, you could see the warm wave passing over Greenland,” she said. “That peak of warm air has passed over the summit of the ice sheet, but the clear skies are almost as important, or maybe even more important, for the total melt of the ice sheet.”
She added that clear skies are likely to continue in Greenland “so we can still get a lot of ice melt even if the temperature is not spectacularly high.” (VOA)

Phishing attacks targeting organisations rose up considerably during the pandemic, as millions of employees working from home became a prime target for cybercriminals. A large majority (83 per cent) of IT teams in India said the number of phishing emails targeting their employees increased during 2020, according to a report by UK-based cybersecurity firm Sophos on Monday.
"It can be tempting for organisations to see phishing attacks as a relatively low-level threat, but that underestimates their power. Phishing is often the first step in a complex, multi-stage attack. According to Sophos Rapid Response, attackers frequently use phishing emails to trick users into installing malware or sharing credentials that provide access to the corporate network," Sophos' Principal Research Scientist, Chester Wisniewski said in a statement. The findings also reveal that there is a lack of common understanding about the definition of phishing. For instance, 67 per cent of IT teams in India associate phishing with emails that falsely claim to be from a legitimate organisation, and which are usually combined with a threat or request for information.

As many as 61 per cent consider Business Email Compromise (BEC) attacks to be phishing, and half of the respondents (50 per cent) think threadjacking - when attackers insert themselves into a legitimate email thread as part of an attack - is phishing. Most of the organisations in India (98 per cent) have implemented cybersecurity awareness programmes to combat phishing. Respondents said they use computer-based training programmes (67 per cent), human-led training programmes (60 per cent), and phishing simulations (51 per cent).
Four-fifths of Indian organisations assess the impact of their awareness programme through the number of phishing-related tickets raised with IT, followed by the level of reporting of phishing emails by users (77 per cent) and click rates on phishing emails (60 per cent). All the organisations surveyed (100 per cent) in Delhi, Hyderabad, and Kolkata say they have a cybersecurity awareness programme in place. This was followed by Chennai where 97 per cent have such programmes, and then, Bengaluru and Mumbai at 96 per cent each. (IANS/ MBI)

Former cricketers have questioned the timing of Virat Kohli's announcement that he will step down as Royal Challengers Bangalore captain at the end of the IPL 2021 season, saying "if you want to do that, you probably do it after the tournament". Three days back, Kohli had also dropped a bombshell -- just a month before the ICC World T20 to begin -- that he will stand down from Team India T20 captaincy after the mega sporting spectacle in UAE and Oman.
On Sunday night, he shared the news on Twitter - just hours before their first game in the resumed IPL 2021 on Monday -- that he will quit RCB captaincy as well. The timings of both the announcements have left the former cricketers a bit "surprised". They believe that Kohli has "unsettled" his RCB side.

The match against Kolkata Knight Riders (KKR) in the United Arab Emirates will be'Kohli's 200th for Bangalore. Former India opener Gautam Gambhir said Kohli's timing had surprised him and would not help Bangalore's quest for a first IPL title. "If you want to do that, you probably do it after the tourn"ment," Gambhir said on Star Sp"rts. "Because it makes the team unsettled and emotional as well." Whereas, former batsman Sanjay Manjrekar said, "I am just curious about both the announcements as to why he had to do it before the tournaments," Manjrekar was quoted as saying by ESPNcricinfo.
Kohli was made Bangalore's captain in 2013, but despite his superstar status, the team's best finish was losing in 2016 final. Kohli insisted his decision had been "well thought (out) and in the best interest of this wonderful franchise". (IANS/ MBI)
