2 more Indians on board quarantined cruise ship tested positive for COVID-19

Beijing, Apr 17: China denied Friday it had covered up the extent of its coronavirus outbreak, as it responded to growing questions from Western powers led by the United States.

A foreign ministry spokesman acknowledged that the virus's rapid spread had contributed to undercounting that resulted in China raising its death toll earlier Friday, but he added "there has never been any concealment, and we'll never allow any concealment."

The allegations China is too close to the World Health Organization (WHO), were an attempt at "smearing" Beijing, Zhao said.

US President Donald Trump has questioned China's handling of the pandemic and whether it had been completely transparent since the virus emerged in the central city of Wuhan late last year.

On Thursday, British Foreign Secretary Dominic Raab and French President Emmanuel Macron also expressed doubts about China's virus response.

These doubts were spotlighted again on Friday when authorities in Wuhan, which has borne the brunt of Chinese deaths, abruptly raised its death toll by 50 percent -- or 1,290 deaths -- to a new total of 3,869.

That also pushed the nationwide death toll up sharply to 4,632, based on official national data released earlier in the day.

Wuhan authorities cited several reasons for the missed cases, including that the city's medical staff were overwhelmed in the early days as infections climbed, leading to "late reporting, omissions or mis-reporting".

Zhao said such miscounting was to be expected in the initial stages of a major disease outbreak.

US President Donald Trump -- under fire himself for initially denying the seriousness of the pandemic -- has accused the WHO of doing the same and being too trusting of China's assurances over the outbreak.

On Tuesday he announced a suspension of US funding to the world body.

Asked about the US allegations, Zhao defended the WHO and China.

"I think they are all smearing China and cooking up stories about China," he said, without specifying which countries he was referring to.

China has largely brought the contagion under control domestically via tough measures including the unprecedented lockdown of Wuhan and tens of millions of people in surrounding areas, but not before it spread worldwide.

Washington, Apr 17: A record number of 4,591 Americans have died in the last 24 hours due to the deadly novel coronavirus in the US, which has the highest number of COVID-19 casualties in the world.

According to the Johns Hopkins University data, by 8 pm on Thursday, as many as 4,591 Americans have died in the last 24 hours, The Wall Street Journal said.

The previous highest was 2,569 on Wednesday.

By Thursday, more than 662,000 Americans tested positive with the coronavirus.

The dreaded disease, which originated in Wuhan city in China in December last year, has so far claimed more than 144,000 lives and infected over 2.1 million people.

The virus has infected over 671,000 people and claimed more than 33,000 lives, the highest for any country in the world.

New York City and its adjoining areas, including New Jersey and Connecticut have emerged as the epicenter of the virus in the US.

New York alone accounts for 226,000 cases of infections and 16,106 deaths.

In New Jersey, as many as 3,518 people have died of the disease and 75,317 have tested positive.

According to the US Centers for Disease Control and Prevention, till April 14, four per cent of the Americans infected with COVID-19 were of Asian origin and nearly one-third (30 per cent) were African Americans.

US President Donald Trump told reporters at the White House that experts and scientists report that his strategy to slow the spread of the virus has saved hundreds of thousands of lives.

Models predicted between 1.5 million and 2.2 million US deaths. If there was no mitigation, it could have even been higher than that and between 100,000 and 240,000 deaths with mitigation. It is looking like we will come far under even these lowest numbers, he said.

Noting that experts say the curve of the virus has flattened, and the peak in the new cases has passed, Trump said that nationwide, more than 850 counties or nearly 30 per cent of the country have reported no new cases in the last seven days.

Because of our early and aggressive action, we have avoided the tragedy of health care rationing and deadly shortfalls that have befallen in many other nations, nations which wherever possible we are helping, he said.

According to Trump, at least 35 clinical trials are already underway, including antiviral therapies, immune therapies, and blood therapies in the form of convalescent plasma. So far, more than 3.5 million tests have been carried out.

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%.
