End of trade war? USA, China agree to roll back tariffs

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%.

Beijing, Mar 29: In a rare display of public anger in China, dozens of people in central Hubei province, the epicentre of the coronavirus outbreak till recently, attacked official vehicles after they were stopped from crossing a bridge and travel to neighbouring Jiangxi after the lifting of the lockdown.
Hubei province with over 56 million people was kept under lockdown from January 23 as part of aggressive measures to bring down COVID-19 cases which rapidly spread in the area.

Videos on Chinese social media on Friday showed unprecedented scenes of police from Hubei and Jiangxi clashing on the bridge connecting the two provinces over barricades erected from stopping Hubei people from moving out over fears of coronavirus spreading.

Policemen from both sides argued over how to verify if people were allowed to enter Jiangxi, according to local media reports.

It was a major relief for millions of people in Hubei province, when the Chinese government which kept it under lockdown lifted the restrictions on travel.

The government will permit people from the province to travel if they hold a green health code, meaning no contact with any infected or suspected COVID-19 cases.

But people of Hubei to their shock on Friday found roadblocks on the 1st Yangtze River Bridge that separates Huangmei county in Hubei erected by Huangmei county of Jiangxi province.

In local media reports, witnesses were quoted as saying that Huangmei police in Jiujiang erected roadblocks on the bridge to stop people from Hubei from crossing it, a move they alleged stigmatised them.

Video footage shared online showed rows of police armed with riot shields holding back the crowds, while members of the public could be seen damaging and even overturning police vehicles.

In a clip published by the Huanggang city government, which administers Huangmei, the county's Communist Party chief Ma Yanzhou could be heard speaking to the people through a loud hailer, warning them that by gathering in a large group they were increasing their chances of contracting the virus, Hong Kong-based South China Morning Post reported.

While it is unclear exactly how the clash started, police from the two sides published separate official statements online, which were quickly deleted, it said.

The incident underlines the problems China faces as it seeks a return to normalcy after months of lockdown, the Post said.

After the incident, the governments of Huangmei and Jiujiang on Friday issued a joint statement saying they had agreed to remove the barriers set up to restrict travel during the lockdown, and also to recognise each other's health screening codes to make it easier for people in good health to get to where they needed to be, the Post report said.

An article by the ruling Communist Party of China (CPC) mouthpiece, People''s Daily acknowledged the problems in getting the country back on its feet.

"In the past few days, all walks of life have called for governments to accept workers from Hubei," it said.

"However, it is undeniable that some places, intentionally or not, have set up obstacles for Hubei migrant workers to return to their posts and hold prejudices against them."

Wellington, Mar 25: New Zealand has declared a state of emergency as it prepares to go into an unprecedented lockdown late Wednesday for about a month.

The declaration temporarily gives police and the military extra powers. And Prime Minister Jacinda Ardern says any New Zealanders returning home from overseas who show symptoms of COVID-19 will be put in isolation at an approved facility.

“I have one simple message for New Zealanders today as we head into the next four weeks: ‘stay at home,’” Ardern said. “It will break the chain of transmission and it will save lives.”

Ardern said exceptions include people working crucial jobs, those leaving to pick up essentials like groceries, and those engaging in solitary exercise.

The country has 205 reported cases of the virus, although Ardern said that number could rise into the thousands before it begins to recede even with the strict measures being taken.
