Suspected debris from missing Malaysian jet may have sunk: Australia

Melbourne, July 1: Authorities will lock down around 300,000 people in suburbs north of Melbourne for a month from late on Wednesday to contain the risk of infection after two weeks of double-digit rises in new coronavirus cases in Australia's second-most populous state.

Australia has fared better than many countries in the pandemic, with around 7,830 cases and 104 deaths, but the recent surge has stoked fears of a second wave of COVID-19, echoing concerns expressed in other countries.

Globally, coronavirus cases exceeded 10 million on Sunday, a major milestone in the spread of a disease that has killed more than half a million people in seven months.

From midnight, more than 30 suburbs in Australia's second-biggest city will return to stage three restrictions, the third-strictest level in curbs to control the pandemic. That means residents will be confined to home except for grocery shopping, health appointments, work or caregiving, and exercise.

The restrictions will be accompanied by a testing blitz that authorities hope will extend to half the population of the area affected, and for which borders will be patrolled, authorities said. The measures come as curbs ease across the rest of the state of Victoria, with restaurants, gyms and cinemas reopening in recent weeks.

Victoria recorded 73 fresh cases on Tuesday from 20,682 tests, following an increase of 75 cases on Monday. State premier Daniel Andrews warned on Wednesday that the return of broader restrictions across city remained a possibility.

"If we all stick together these next four weeks, we can regain control of that community transmission ... across metropolitan Melbourne," Andrews said at a briefing. "Ultimately if I didn't shut down those postcodes I'd be shutting down all postcodes. We want to avoid that."

Victoria's spike in cases has been linked to staff members at hotels housing returned travellers for which quarantine protocols were not strictly followed. Victorian state authorities have announced an investigation into the matter.

Some other Australian states and territories are preparing to open borders, but applying limits and quarantine measures to citizens of Victoria as the school holiday season gets under way.

South Australia, the country's fifth most populous state, has had just three new cases in the past month. But citing the spike in coronavirus infections, on Tuesday it cancelled its scheduled reopening to other parts of the nation.

New South Wales (NSW), Australia's most populous state, has stopped short of closing its borders to all Victorians, but those holidaying from hotspot areas - not permitted under NSW rules - can be handed a fine of A$11,000 ($7,596) or jailed if they are detected, state authorities said.

The delays reopening internal borders cast doubts over a federal plan to set up "travel bubble" with neighbouring New Zealand that would allow movement between the two countries.

India continues to remain ranked 43rd on an annual World Competitiveness Index compiled by Institute for Management Development (IMD) with some traditional weaknesses like poor infrastructure and insufficient education investment keeping its ranking low, the international business school said on Tuesday.

Singapore has retained its top position on the 63-nation list.

Denmark has moved up to the second position (from 8th last year), Switzerland has gained one place to rank 3rd, the Netherlands has retained its 4th place and Hong Kong has slipped to the fifth place (from 2nd in 2019).

The US has moved down to 10th place (from 3rd last year), while China has also slipped from 14th to 20th place. Among the BRICS nations, India is ranked second after China, followed by Russia (50th), Brazil (56th) and South Africa (59th).

India was ranked 41st on the IMD World Competitiveness Ranking, being produced by the business school based in Switzerland and Singapore every year since 1989, but had slipped to 45th in 2017 before improving to 44th in 2018 and then to 43rd in 2019.

While its overall position has remained unchanged in the 2020 list, it has recorded improvements in areas like long-term employment growth, current account balance, high-tech exports, foreign currency reserves, public expenditure on education, political stability and overall productivity, the IMD said.

However, it has moved down in areas like exchange rate stability, real GDP growth, competition legislation and taxes.

Arturo Bris, Head of Competitiveness Center at IMD Business School, said India continues to struggle on the list and the recent country rating downgrade by Moody’s reflects the uncertainties regarding the economy’s future.

"In our ranking this year, we again emphasize the traditional weaknesses of India -- poor infrastructure, an important deficit in education investment, and a health system that does not reach everybody. For India to follow the path of China, it must stress its intangible infrastructure," Bris said.

"In a less global world, with China, USA, and Europe looking inwards, currencies like the rupee (and the Brazilian real for instance) are going to suffer and display high volatilities.

"Moody’s has threatened the country with a downgrade to junk and that would put India in a terrible position to attract foreign capital. So the urgency for the government should be to fix the short-term problems—and this requires to improve the credibility of the government itself," Bris added.

With the exception of Singapore, the Philippines, Taiwan and the Korean Republic, most Asian economies dropped in rankings this year, the IMD said.

The reason for the Asian economies’ less stellar performance as a region, this year is partly the result of the trade frictions between China and the US, particularly because these economies are highly dependent on trade with China.

About Singapore, which moved to the top rank last year, the IMD said its position is largely driven by the relative ease of setting up business, availability of skilled labour and its cutting-edge technological infrastructure.

The IMD said the impact of COVID-19 on the competitiveness ranking has partially been captured by executives’ opinions about the effectiveness of the different health systems.

In the ASEAN countries included in the survey, only Singapore and Thailand have a positive performance in the effectiveness of the health infrastructure.

Kensington (United States), May 20: The world cut its daily carbon dioxide emissions by 17% at the peak of the pandemic shutdown last month, a new study found.

But with life and heat-trapping gas levels inching back toward normal, the brief pollution break will likely be “a drop in the ocean" when it comes to climate change, scientists said.

In their study of carbon dioxide emissions during the coronavirus pandemic, an international team of scientists calculated that pollution levels are heading back up — and for the year will end up between 4% and 7% lower than 2019 levels.

That's still the biggest annual drop in carbon emissions since World War II.

It'll be 7% if the strictest lockdown rules remain all year long across much of the globe, 4% if they are lifted soon.

For a week in April, the United States cut its carbon dioxide levels by about one-third.

China, the world's biggest emitter of heat-trapping gases, sliced its carbon pollution by nearly a quarter in February, according to a study Tuesday in the journal Nature Climate Change. India and Europe cut emissions by 26% and 27% respectively.

The biggest global drop was from April 4 through 9 when the world was spewing 18.7 million tons (17 million metric tons) of carbon pollution a day less than it was doing on New Year's Day.

Such low global emission levels haven't been recorded since 2006. But if the world returns to its slowly increasing pollution levels next year, the temporary reduction amounts to ''a drop in the ocean," said study lead author Corinne LeQuere, a climate scientist at the University of East Anglia.

“It's like you have a bath filled with water and you're turning off the tap for 10 seconds," she said.

By April 30, the world carbon pollution levels had grown by 3.3 million tons (3 million metric tons) a day from its low point earlier in the month. Carbon dioxide stays in the air for about a century.

Outside experts praised the study as the most comprehensive yet, saying it shows how much effort is needed to prevent dangerous levels of further global warming.

“That underscores a simple truth: Individual behavior alone ... won't get us there,” Pennsylvania State University climate scientist Michael Mann, who wasn't part of the study, said in an email.

“We need fundamental structural change.”

If the world could keep up annual emission cuts like this without a pandemic for a couple decades, there's a decent chance Earth can avoid warming another 1.8 degrees (1 degree Celsius) of warming from now, study authors said. But getting the type of yearly cuts to reach that international goal is unlikely, they said.

If next year returns to 2019 pollution levels, it means the world has only bought about a year's delay in hitting the extra 1.8 degrees (1 degree Celsius) of warming that leaders are trying to avoid, LeQuere said. That level could still occur anywhere from 2050 to 2070, the authors said.

The study was carried out by Global Carbon Project, a consortium of international scientists that produces the authoritative annual estimate of carbon dioxide emissions. They looked at 450 databases showing daily energy use and introduced a measurement scale for pandemic-related societal “confinement” in its estimates.

Nearly half the emission reductions came from less transportation pollution, mostly involving cars and trucks, the authors said. By contrast, the study found that drastic reductions in air travel only accounted for 10% of the overall pollution drop.

In the US, the biggest pollution declines were seen in California and Washington with plunges of more than 40%.
