China developing stealth drones to evade anti-aircraft missiles

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%.

Tel Aviv, Jan 4: Israeli Prime Minister Benjamin Netanyahu on Friday came out in the support of Trump administration for carrying out the strike near Baghdad's international airport which led to the killing of Iran's elite IRGC Qassem Soleimani, saying that "The US has the right of self-defence."

"Just as Israel has the right of self-defence, the United States has exactly the same right. Qassem Soleimani is responsible for the death of American citizens and many other innocent people. He was planning more such attacks," PM Benjamin Netanyahu wrote on Twitter.

In another tweet, Netanyahu also credited US President Donald Trump for acting decisively in the operation of Iraq that led to the killing of Qassem Soleimani -- a US-designated terrorist, along with six others.

"President Donald Trump deserves all the credit for acting swiftly, forcefully and decisively. Israel stands with the United States in its just struggle for peace, security and self-defence," he added.

Meanwhile, Iran on Friday vowed to take a "vigorous revenge" over the killing of General Qassem Soleimani, the head of Iran's elite IRGC.

The US had accused Soleimani of orchestrating several attacks on coalition bases in Iraq including the December 27 attack in which American and Iraqi personnel were killed. 

Feb 12: China on Wednesday reported another drop in the number of new cases of a viral infection and 97 more deaths, pushing the total dead past 1,100 as postal services worldwide said delivery was being affected by the cancellation of many flights to China.

The National Health Commission said 2,015 new cases had been reported over the last 24 hours, declining for a second day. The total number of cases in mainland China reached 44,653, although many experts say a large number of others infected have gone uncounted.

The additional deaths raised the mainland toll to 1,113. Two people have died elsewhere, one in Hong Kong and one in the Philippines.

In the port city of Tianjin, just southeast of Beijing, a cluster of cases has been traced to a department store in Baodi district. One-third of Tianjin’s 104 confirmed cases are in Baodi, the Xinhua state news agency reported.

A salesperson working in the store’s small home appliance section became the first individual in the cluster to be diagnosed on Jan. 31, Xinhua said. The store was already closed at that point, then disinfected on Feb. 1. Nevertheless, several more diagnoses soon followed.

The next to have their infections confirmed were also salespeople at the store. They had not visited Wuhan recently and, with the exception of one married couple, the patients worked in different sections of the store and did not know one another, according to Xinhua.

Japan’s Health Ministry said that 39 new cases have been confirmed on a cruise ship quarantined at Yokohama, bringing the total to 174 on the Diamond Princess.

The U.S. Postal Service said that it was “experiencing significant difficulties” in dispatching letters, parcels and express mail to China, including Hong Kong and Macau.

Both the U.S. and Singapore Post said in notes to their global counterparts that they are no longer accepting items destined for China, “until sufficient transport capacity becomes available.”

The Chinese mail service, China Post, said it was disinfecting postal offices, processing centers and vehicles to ensure the virus doesn’t spread via the mail and to protect staff.

It said the crisis is also impacting mail that transits China to other destinations including North Korea, Kazakhstan, Kyrgyzstan, Mongolia, Tajikistan, Turkmenistan, Uzbekistan and Vietnam.

The World Health Organization has named the disease caused by the virus as COVID-19, avoiding any animal or geographic designation to avoid stigmatization and to show the illness comes from a new coronavirus discovered in 2019.

The illness was first reported in December and connected to a food market in the central Chinese city of Wuhan, where the outbreak has largely been concentrated.

Zhong Nanshan, a leading Chinese epidemiologist, said that while the virus outbreak in China may peak this month, the situation at the center of the crisis remains more challenging.

“We still need more time of hard working in Wuhan,” he said, describing the isolation of infected patients there a priority.

“We have to stop more people from being infected,” he said. “The problem of human-to-human transmission has not yet been resolved.”

Without enough facilities to handle the number of cases, Wuhan has been building prefabricated hospitals and converting a gym and other large spaces to house patients and try to isolate them from others.

China’s official media reported Tuesday that the top health officials in Hubei province, of which Wuhan is the capital, have been relieved of their duties. No reasons were given, although the province’s initial response was deemed slow and ineffective. Speculation that higher-level officials could be sacked has simmered, but doing so could spark political infighting and be a tacit admission of responsibility.

The virus outbreak has become the latest political challenge for the party and its leader, Xi Jinping, who despite accruing more political power than any Chinese leader since Mao Zedong, has struggled to handle crises on multiple fronts. These include a sharply slowing domestic economy, the trade war with the U.S. and pushback on China’s increasingly aggressive foreign policies.

China is struggling to restart its economy after the annual Lunar New Year holiday was extended to try to curb the spread of the virus. About 60 million people are under virtual quarantine and many others are still working at home.

In Hong Kong, the diagnosis of four people living in an apartment building prompted worried comparisons with the deadly SARS pandemic of 17 years ago.

More than 100 people were evacuated from the building after a 62-year-old woman diagnosed with the virus was found living 10 floors directly below a man who was earlier confirmed with the virus.

Health officials called it a precautionary measure and sought to assuage fears of an epidemic, dismissing similarities to the SARS community outbreak at the Amoy Gardens housing estate in 2003.
