Mysterious US space plane lands on California coast

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%.

The President of United States Donald Trump has said that countries like India and China would have much more coronavirus cases than America if they conduct more tests.

“I say to my people every time we test; you find cases because we do more testing. If we have more cases, if we wanted to do testing in China or in India or other places, I promise you there would be more cases you are doing a fantastic job in getting out the swabs,” the US president said on Friday.

Trump said that the US has carried out 20 million tests while compared to America, Germany is at four million and much talked about South Korea is about three million tests. He made the remarks at Puritan Medical Products in Maine, according to Johns Hopkins Coronavirus Resource Center.

The US has reported nearly 1.9 million cases and over 1,09,000 deaths while the total number of coronavirus cases in India and China stand at 2,36,184 and 84,177 respectively, according to Johns Hopkins Coronavirus Resource Center data.

India has so far conducted over 4 million COVID-19 tests, according to the health ministry.

Trump said, “we will be well over 20 million tests. Remember this, when you test more, you have more cases.”

“Puritan is one of the only manufacturers in the world producing high-quality medical swabs that are crucial for rapid testing. And every swab you make at Puritan is proudly stamped with the beautiful phrase made in the USA,” Trump said.

“Thanks to the testing capacity that you are making possible, our country is reopening and our economy is recovering like nobody would’ve thought possible,” he added.

Trump also spoke about the huge unemployment problem the country is currently facing. He said that the economy is now back on track, referring to the latest monthly employment numbers,.

“We absolutely shattered expectations, and this is the largest monthly jobs increase in American history, think of that; that’s a long time,” Trump said

“I think it’s more than double or about double of what our highest was before so this is the largest monthly job increase in American history. And we’re going to have a phenomenal next year. We’re going to have a tremendous couple of months prior to the election on November 3 very, very important date,” the president said.

Keeping an eye on the November 3 presidential elections, Trump is seeking re-election for his second consecutive term. He is pitted against Democratic presidential nominee Joe Biden who in opinion polls is surging several points of Trump.

“It’s going to be a very important election because the only thing that can screw it up is if you get the wrong president and they raise your taxes, and they open up your borders so that everybody pours into our country,” Trump said.

Trump also vowed to bring the American economy back on track, which has been badly hit by the coronavirus pandemic. He reiterated that his administration has built a strong economy in the last three years.

Describing the fight against coronavirus as the greatest national and industrial mobilisation since the World War II, Trump said that his administration has marshaled the full power of the US government and US industry to defeat the invisible enemy.

“It is indeed an enemy. It came from China, should have been stopped in China. They didn’t do that,” he alleged.

The administration, he said, has delivered over 1.5 billion pieces of personal protective equipment to doctors and nurses on the front lines. We slashed the red tape to speed up the development of vaccines.

“And vaccines are coming along incredibly well, wait till you see, and therapeutics. And we partnered at private sector leaders such as Puritan to build the largest and most advanced testing capacity on the face of the earth, like this one,” the US president said.

The Puritan factory in Maine, he said, quickly ramped up the production to produce nearly 20 million foam-tipped swabs each month.

“Then in April, my administration invoked the Defence Production Act to help you scale up even more. Under a USD 75 million public-private partnership, Puritan will soon double production to 40 million swabs per month,” Trump added.

Washington, May 8: Four top Republican senators have urged US President Donald Trump to suspend all-new guest worker visas for 60 days and some of its categories, including the H-1B visa, for at least the next year or until unemployment figures return to normal levels in the country.

The unemployment figures in the US have reached an all-time high due to the coronavirus pandemic. The letter has been signed by Senators Ted Cruz, Tom Cotton, Chuck Grassley and Josh Hawley.

"As you know, more than 33 million Americans have filed for unemployment coverage just since mid-March, and approximately one-fifth of the American workforce is currently out of work. This is a stunning difference compared with the historically-low nationwide unemployment rate of just 3.5 per cent in February this year," they said in their letter to the president on Thursday.

The letter, dated May 7, specifically calls for suspension of all non-immigrant guest worker visas for the next 60 days, followed by a continued suspension of certain categories of new non-immigrant guest worker visas for a year or until the national unemployment figures return to normal levels.

"To protect unemployed Americans in the early stages of economic recovery, we urge you to suspend all non-immigrant guest worker visas for the next 60 days," the senators said.

Exceptions to this suspension should be rare, limited to time-sensitive industries such as agriculture and issued only on a case-by-case basis, when the employers can demonstrate that they have been unable to find Americans to take the jobs, the senators wrote.

After 60 days, the senators urged Trump to continue to suspend new non-immigrant guest workers for a year or until the national unemployment figures return to normal levels, whichever comes first.

"That suspension should, at a minimum, include H-2B visas (non-agricultural seasonal workers), H-1B visas (specialty occupation workers) and the Optional Practical Training (OPT) program (extension of foreign student visas after graduation). We also urge you to suspend the EB-5 immigrant visa program, effective immediately," the lawmakers wrote.

The H-1B work visa for foreign technology professionals is highly popular among Indians and a large number of Indians also opt for the EB-5 investors visa.

The senators argued that there is no reason why unemployed Americans and recent college graduates should have to compete in such a limited job market against an influx of additional H-1B workers, most of whom work in business, technology or STEM fields.

"Temporarily suspending the issuance of new H-1B visas would also protect the hundreds of thousands of H-1B workers and their families already working in the United States -- workers who could otherwise be subject to deportation if they are laid off for more than 60 days," they said.

"Of course, appropriate exceptions could also be crafted to the H-1B program suspension to allow for doctors, nurses and other healthcare professionals who wish to come to the United States to assist in combating the coronavirus pandemic," the senators wrote.

Additionally, the United States ought to suspend its Optional Practical Training (OPT) programme, which allows foreign students in the country to extend their stay after graduation for one to three years to get "experience in the field" by taking jobs here, they wrote.

In 2019, more than 223,000 former foreign students had their OPT applications approved or extended. While the merits of such a programme are subject to debate, there is certainly no reason to allow foreign students to stay for three additional years just to take jobs that would otherwise go to unemployed Americans as the country's economy recovers, the lawmakers said.

The senators also urged Trump to remove the EB-5 visa from the exemptions in his Presidential Proclamation issued on April 22, at least until real reforms are adopted.

The EB-5 programme has long been plagued by scandal and fraud, and criticised as effectively functioning as a pay-for-citizenship scheme in many cases. There is no reason that the programme should receive preferential treatment as opposed to other green card programmes for employment-based immigrants, the lawmakers said.
