Global warming causing ‘irreversible’ mass melting in Antarctica says scientist
UNTV News • February 19, 2020 • 445
Global warming was leading to an “irreversible” mass melting of the Antarctic ice and purging carbon from the atmosphere was the only solution to slow the process, an Australian climate scientist told Reuters on Wednesday (February 19).
Recent human activity has intensified global warming, which could result in a mass melting of Antarctica, said Zoe Thomas, a research fellow at the University of New South Wales who was part of an international team of scientists that recently published a paper on Antarctic ice melting.
The study showed the world could lose most of the West Antarctic Ice Sheet, which rests on the seabed and is fringed by floating ice, in a warmer world.
“What we’re seeing with the West Antarctic Ice Sheet is that this starting of the melt, once we reach a certain threshold, will continue despite our efforts to stop it,” she told Reuters.
The hottest temperature ever recorded in Antarctica of 18.3 degrees Celsius (64.94 degrees Fahrenheit) was taken at a research base there on Feb. 6. If hotter temperatures were to sustain they could cause an extreme global sea level rise.
“This will gradually displace people as it goes,” Thomas said. “We know this is already happening in small island communities and this will just continue to happen gradually as more and more houses are being inundated at high tide, then at normal tide and then even at low tide.”
Thomas said that the only thing that would slow down the ice melting was if economies across the world began de-carbonising themselves.
Many advanced economies have pledged to cut carbon emissions to net zero by 2050 though Australia is largely seen as dragging its feet on the issue despite recently suffering one of its worst bushfire seasons ever. (Reuters)
President Donald Trump urged Americans on Monday (March 16) to halt most social activities for 15 days and not congregate in groups larger than 10 people in a newly aggressive effort to reduce the spread of the coronavirus in the United States.
Announcing new guidelines from his coronavirus task force, the president said people should avoid discretionary travel and not go to bars, restaurants, food courts or gyms.
As stocks tumbled, Trump warned that a recession was possible, a development that could affect his chances of re-election in November. The Republican president said he was focused on addressing the health crisis and that the economy would get better once that was in line.
The task force implored young people to follow the new guidelines even though they were at lesser risk of suffering if they contract the virus. Older people, especially those with underlying health problems, are at the greatest risk if they develop the respiratory disease.
Reporters staggered their seating, sitting in every other seat in the White House briefing room, to follow social distancing measures.
Trump said the worst of the virus could be over by July, August or later. He called it an invisible enemy.
The president has taken criticism for playing down the seriousness of the virus in the early days of its U.S. spread. On Monday, when asked, he gave himself a good grade for his response.
“I’d rate it a 10. I think we’ve done a great job,” he said.
Trump said a nationwide curfew was not under consideration at this point.
Normally a cheerleader for the U.S. economy, he acknowledged the possibility of a recession while brushing off another dramatic decline on stock markets as investors worried about the virus.
“We’re not thinking in terms of recession, we’re thinking in terms of the virus. Once we stop, I think there’s a tremendous pent up demand, both in terms of the stock market and in terms of the economy,” Trump said. The president has long considered soaring stock markets to be a sign of his administration’s success.
Trump said the administration had talked regularly about domestic travel restrictions but hoped not to have to put such measures in place.
He said he thought it would still be possible for G7 leaders to meet at the Camp David retreat in Maryland in June. Trump upset European countries, which make up a large part of the G7, by instituting travel restrictions from European countries without consulting with them first. (Reuters)
A handful of people were seen on the streets of Milan on Wednesday morning (March 12) following stringent measures imposed to contain the coronavirus.
Shops and restaurants closed, hundreds of flights were cancelled and streets emptied across Italy on Tuesday (March 10), the first day of an unprecedented, nationwide lockdown imposed to slow Europe’s worst outbreak of coronavirus.
Just hours after the dramatic new restrictions came into force, health authorities announced the death toll had jumped by 168 to 631, the largest rise in absolute numbers since the contagion came to light on Feb. 21.
The total number of confirmed cases rose at a much slower rate than recently seen, hitting 10,149 against a previous 9,172, but officials warned that the region at the epicentre, Lombardy, had provided incomplete data.
The government has told all Italians to stay at home and avoid non-essential travel until April 3, radically widening steps already taken in much of the wealthy north, which is the epicentre of the spreading contagion. (Reuters)
The Russian lower house of parliament on Wednesday (March 11) gave its definitive approval to constitutional changes that allow Vladimir Putin to run for president again in 2024, something the current constitution forbids.
The 450-seat State Duma, the lower house of parliament, voted in favour of the changes in a third and final reading by 383 votes.
Nobody voted against, but 43 lawmakers abstained. Twenty-four lawmakers were absent.
Putin told parliament in televised comments on Tuesday he believed a constitutional amendment that would allow him to run for president again could be adopted if Russia’s Constitutional Court did not object.
Putin is required by the constitution to step down in 2024 when his second sequential presidential term ends. (Reuters)
