Condemn this terror attack on Muslims: Canadian PM on Quebec mosque shooting

Global coronavirus infections passed 14 million on Friday, according to a Reuters tally, marking the first time there has been a surge of 1 million cases in under 100 hours.

The first case was reported in China in early January and it took three months to reach 1 million cases. It has taken just four days to climb to 14 million cases from 13 millionrecorded on July 13.

The United States, with more than 3.6 million confirmed cases, is still seeing huge daily jumps in its first wave of Covid-19 infections. The United States reported a daily global record of more than 77,000 new infections on Thursday, while Sweden has reported 77,281 total cases since the pandemic began.

Despite the surging cases, a cultural divide is growing in the country over wearing masks to slow the spread of the virus, a precaution routinely taken in many other nations.

U.S. President Donald Trump and his followers have resisted a full-throated endorsement of masks and have been calling for a return to normal economic activity and reopening schools despite the surging cases.

COVID-19 Pandemic Tracker: 15 countries with the highest number of coronavirus cases, deaths

Other hard-hit countries have “flattened the curve” and are easing lockdowns put in place to slow the spread of the novel virus while others, such as the cities of Barcelona and Melbourne, are implementing a second round of local shutdowns.

The number of cases globally is around triple that of severe influenza illnesses recorded annually, according to the World Health Organization.

The pandemic has now killed more than 590,000 people in almost seven months, edging towards the upper range of yearly influenza deaths reported worldwide. The first death was reported on Jan. 10 in Wuhan, China before infections and fatalities then surged in Europe and later in the United States.

The Reuters tally, which is based on government reports, shows the disease is accelerating the fastest in the Americas, which account for more than half the world’s infections and half its deaths.
In Brazil, more than 2 million people have tested positive including President Jair Bolsonaro, and more than 76,000 people have died.

India, the only other country with more than 1 millioncases, has been grappling with an average of almost 30,000 new infections each day for the last week.

Those countries were the main drivers behind the World Health Organization on Friday reporting a record one-day increase in global coronavirus cases of 237,743.

In countries with limited testing capacity, case numbers reflect only a proportion of total infections. Experts say official data likely under-represents both infections and deaths.

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%.

Paris, May 10: The number of coronavirus cases worldwide topped four million as some of the hardest-hit countries readied Sunday to lift lockdown restrictions despite concern about a second wave of infections.

Governments around the world are trying to stop the spread of the deadly disease while scrambling for ways to relieve pressure on their economies, which are facing a historic downturn with millions pushed into unemployment.

Despite the intense political pressure to reopen, nations are also keen to avoid second waves of infections that could overwhelm healthcare systems, with reminders over the weekend of the threat posed by the virus.

In the United States, media reported Saturday that the nation's top infectious disease expert, Anthony Fauci, was among three members of the White House coronavirus task force who will self-isolate after potential exposure.

And in South Korea, the capital Seoul shut all bars and clubs on Saturday as more than 50 cases were linked to a man who tested positive after spending time in one of the city's busiest nightlife districts.

Despite the risks, some governments in hard-hit Europe have said are signs of progress that justify cautious steps towards normality.

Officials in France on Saturday said the day's death toll of 80 was the lowest since early April, while nursing home fatalities also fell sharply as the nation prepared to relax curbs on public movement imposed eight weeks ago.

The easing, to begin Monday, has brought mixed reactions.

"I've been scared to death" about the reopening, said Maya Flandin, a bookshop manager from Lyon. "It's a big responsibility to have to protect my staff and my customers."

French health officials have warned that social distancing must be kept up even as restrictions are eased.

In Spain, about half the population will be allowed out on Monday for limited socialisation, and restaurants will be able to offer some outdoor service as the country begins a phased transition set to last through June.

With lingering fears of a resurgence, authorities excluded Madrid and Barcelona -- two COVID-19 hotspots -- from the first phase.

Belgium is also easing some restrictions on Monday, and in some parts of Germany, bars and restaurants reopened on Saturday with further easing set for Monday.

In Britain, Prime Minister Boris Johnson is expected Sunday to lay out a plan for the nation to emerge out of its current lockdown.

Media reports have suggested that Britain may introduce a mandatory 14-day quarantine for international arrivals to stop the spread of the virus.

Global economic figures are pointing to the most acute downturn in nearly a century, with businesses forced to shut and supply lines badly disrupted, and pressure is growing on leaders around the world to find a way out as the worldwide death toll topped 277,000 and infections crossed four million.

In the United States, the country with the highest death toll and where more than 20 million people have lost their jobs, President Donald Trump has insisted that next year would be "phenomenal" for the economy, urging reopening despite the virus still claiming well over 1,000 lives daily in the country.

The scale of the challenge was brought in sharp focus over the weekend as US media reported that top disease expert Anthony Fauci, who has become the trusted face of the government response to the pandemic, is going to self-isolate after possible exposure to an infected White House staffer.

Fauci told CNN that he will undergo a "modified quarantine" as he had not been in close proximity to the staffer, the network reported. He will remain at home teleworking, and will wear a mask for two weeks.

Robert Redfield, the director of the Centers for Disease Control and Prevention, and Stephen Hahn, the commissioner of the Food and Drug Administration, will also self-isolate, CNN added.

All three will still testify at Tuesday's Senate coronavirus hearing, with Redfield and Hahn participating via video link, according to Senator Lamar Alexander, chairman of the chamber's health committee.

It is believed Fauci will attend wearing a mask, CNN reported.

President Trump has faced sharp criticism from his predecessor Barack Obama, who said on a leaked tape that Trump's handling of the crisis was an "absolute chaotic disaster".

With people wearying of being indoors and under economic pressure, anti-lockdown protests have been held in a number of countries in recent weeks, with some demonstrators arguing that such restrictions violate their rights and others promoting conspiracy theories about the pandemic.

Ten people were arrested and a police officer injured in Melbourne, Australia, on Sunday in the latest such protest, where around 150 people gathered to demand an end to the shutdown.

Participants were promoting a number of conspiracy theories, such as linking 5G cellular communications to the disease.

Australian chief medical officer Brendan Murphy said there was "a lot of very silly misinformation out there", including the 5G allegation.

"I have unfortunately received a lot of communication from these conspiracy theorists myself," he said.

"It is complete nonsense. 5G has got nothing at all to do with coronavirus."
