US wants to send team of experts inside China for COVID-19 probe: President Donald Trump

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, Jul 20: Two coronavirus vaccine candidates have proven safe for humans and produced strong immune reactions among patients involved in separate clinical trials, doctors said on Monday.

The first trial among more than 1,000 adults in Britain found that the vaccine induced "strong antibody and T cell immune responses" against the novel coronavirus.

A separate trial in China involving more than 500 people showed most had developed widespread antibody immune response.

The studies, published in The Lancet medical journal, constitute a major step on the road towards a COVID-19 vaccine that is effective and safe for widespread use.

The authors of the studies said that they encountered few adverse side-effects from the vaccine candidates.

However, they cautioned that more research was needed, particularly among older adults, who are disproportionately at risk of dying of COVID-19.

Co-author Sarah Gilbert from the University of Oxford said the results "hold promise".

"If our vaccine is effective, it is a promising option as these types of vaccine can be manufactured at large scale."

Islamabad, Feb 26: Islamabad on Tuesday declared former Prime Minister Nawaz Sharif an absconder while simultaneously denying extending bail to him.

The federal cabinet presided over by Prime Minister Imran Khan, cited that Sharif failed to provide required medical reports and has violated the bail terms.

The government has also decided to freeze gas and electricity tariffs for the next four months, The Dawn reported.

"After Nawaz Sharif failed to submit his medical report of any hospital in London, the medical board rejected a medical certificate sent by him and [the government] declared him an absconder. From today, Nawaz Sharif is an absconder according to the law of land and if he does not return to the country he will be declared a proclaimed offender," said Dr Firdous Ashiq Awan, Special Assistant to the Prime Minister on Information, in a press conference.

She further asserted that the Punjab government, which was authorized by the Islamabad High Court (IHC) to decide Sharif's case on medical grounds, had written several letters asking him to submit his medical report from any hospital in London. However, he failed to do so and only sent a certificate that was not accepted by the medical board.

"If he (Nawaz Sharif) is seriously ill then why a comprehensive medical report is not being submitted to the medical board," Firdous added.

Further, she said that the office of the opposition leader was also waiting for his younger brother and Leader of the Opposition in the National Assembly Shahbaz Sharif, who was also staying in London for 'no reason'.

"He is getting a monthly salary and enjoying luxurious offices and other perks and privileges but not performing his duties required by his office and the people. Shahbaz Sahib, return to the country and justify your salary and other benefits being given from taxpayers' money," Firdous added.

On October 29 last year, the IHC granted bail for eight weeks to Sharif, who was convicted and disqualified in corruption cases, on medical grounds.

Sharif left Pakistan for London along with Shahbaz on November 19, 2019, for his medical treatments there.
