Blasts hit churches, hotels across Sri Lanka; Over 200 killed, 500 injured

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%.

New Delhi, Jan 17: A Delhi court Friday issued fresh death warrants for February 1, 6 am against the four convicts in the Nirbhaya gang rape and murder case.

Additional Sessions Judge Satish Kumar Arora was hearing a plea by one of the four death row convicts in the case, Mukesh Kumar Singh, seeking postponement of the date of his execution scheduled for January 22.

Earlier in the day, the Tihar jail authorities sought issuance of fresh death warrants against the four convicts.

Public Prosecutor Irfan Ahmed told the court that Mukesh's mercy plea was rejected by President Ram Nath Kovind on Friday.

The 23-year-old paramedic student, referred to as Nirbhaya, was gang-raped and brutally assaulted on the intervening night of December 16-17, 2012 inside a moving bus in south Delhi by six persons before being thrown out on the road.

She died on December 29, 2012, at Mount Elizabeth Hospital in Singapore.

Mar 16: A fourth batch of 53 Indians returned to India from Iran on Monday, taking the total number of people evacuated from the coronavirus-hit country to 389.

This comes a day after over 230 Indians were brought back from Iran to New Delhi and quarantined at the Indian Army Wellness Centre in Jaisalmer, the third batch to be evacuated from that country.

"Fourth batch of 53 Indians - 52 students and a teacher - has arrived from Tehran and Shiraz, Iran. With this, a total of 389 Indians have returned to India from Iran. Thank the efforts of the team @India_in_Iran and Iranian authorities," Jaishankar tweeted.

The Indians came in a Mahan Air flight that landed at the Delhi airport at around 3 am, officials said, adding that they were later taken to Jaisalmer in an Air India flight for being quarantined.

The first batch of 58 Indian pilgrims were brought back from Iran last Tuesday and the second group of 44 Indian pilgrim arrived from there on Friday.

Iran is one of the worst-affected countries by the coronavirus outbreak and the government has been working to bring back Indians stranded there. Over 700 people have died from the disease in Iran and nearly 14,000 cases have been detected.

Jaishankar had told Rajya Sabha last week that the government was focusing on evacuating Indians stranded in Iran and Italy as these countries are facing an "extreme situation".
