2017 to be one of the hottest years: study

April 28, 2017

Washington, Apr 28: 2017 will be among the hottest years on record, say scientists who have developed a new method for predicting global mean temperature.hottest

Researchers at Yale University in the US found that weak El Nino activity from 1998 until 2013, rather than a pause in long-term global warming, was the root cause for slower rates of increased surface temperature.

They also found that volcanic activity played only a minor role.

"From a practical perspective, our method, when combined with El Nino prediction, allows us to predict next-year global mean temperature," said Alexey Fedorov, professor at Yale University.

"Accordingly, 2017 will remain among the hottest years of the observational record, perhaps just a notch colder than 2016 or 2015," Fedorov said.

El Nino events contribute to year-to-year variations in global mean temperature by modulating the heat that is released from tropical oceans into the atmosphere, researchers said.

El Nino warms the atmosphere, while the cold phase of the phenomenon, La Nina, cools the atmosphere.

The new model closely mirrors global mean surface temperature (GMST) changes since 1880, including the so-called global warming hiatus and the more recent temperature rise.

"Our main conclusion is that global warming never went away, as one might imply from the term 'global warming hiatus,'" Fedorov said.

"The warming can be masked by inter-annual and decadal natural climate variability, but then it comes back with a vengeance," said Fedorov.

Multiple strong El Nino events occurred in the 1980s and 1990s. This was followed by much weaker El Nino activity, which lasted until 2014.

"The recent rapid rise in global temperature mainly resulted from the prolonged 2014-2016 El Nino conditions in the tropics that reached an extreme magnitude in the winter of 2015," said Shineng Hu, first author of the study published in the journal Geophysical Research Letters.

"The corresponding heat release into the atmosphere, together with the ongoing background global warming trend, made 2014, 2015, and 2016 the three consecutive warmest years of the instrumental record so far," Hu said.

Washington, Mar 18: Hundreds of distressed Indian students, stuck in the Philippines, are seeking help through video messages as they are unable to fly back home due to the travel restrictions imposed by India to contain the spread of the deadly novel coronavirus, according to friends and relatives of some of these students in the US.

The Indian government on Tuesday banned the entry of passengers from Afghanistan, Philippines and Malaysia to India with immediate effect amid stepped up efforts against the spread of COVID-19.

In a video message by one of these students Akhil Bala Nair, around 200 Indian students had booked their flight tickets for India in the next few days. But all of them have been cancelled due to the new policy.

Most of the students, she said, had booked their flights for March 17 and rest were schedule to travel to India on March 19 and 20. But the flights were cancelled and scores of Indian students are now stuck at the airport in Manila, Nair said in the video message sent to Prem Bhandari, head of the Jaipur Foot USA.

“It is need of the hour that the Indian government send a plane to bring these Indian students back home,” Bhandari, who in the past has worked for the cause of the Indian diaspora, and who was approached by these students told PTI.

According to these students, some 100 of them have been at the airport since Tuesday.

They all have confirmed tickets but the airport authorities are not allowing them to check in because of the new travel regulations.

While the airport authorities have asked them to go back to their respective place of residence, the students said they were unable to travel because of the absence of local taxi or shared ride services.

The students said that they are running out of time as the Philippines government has given them 72 hours time to exit the country, which started from March 16, after which the country will go into lockdown.

“This means we would not be able to travel anywhere outside Philippines after March 20,” Nair said in her message.

The students said that there are many of them who have applied for renewal of their visas and are unable to travel to India.

There are nearly 1,000 Indian students presently in Manila who are willing to travel back home, they said.

Meanwhile, the Indian Embassy in Manila, in a tweet, said that they, along with the Ministry of External Affairs, are trying to work out a solution.

“It is requested to all to kindly have patience,” the embassy said.

Panic gripped big tech firms like Facebook and Twitter which decided to close their offices from Seattle to London as more employees tested positive for the new coronavirus.

Facebook shut its three London offices till Monday after an employee was diagnosed with COVID-19.

The social networking giant told nearly 3,000 employees in London to work from home after an employee, who is based in Singapore but visited the London offices between February 24-26, was diagnosed with the new coronavirus, Sky News reported on Friday.

"An employee based in our Singapore office who has been diagnosed with COVID-19 visited our London offices on February 24-26.

"We are therefore closing our London offices until Monday for deep cleaning and employees are working from home until then," the company said in a statement.

There have been 163 cases of coronavirus so far in the UK.

Earlier, Facebook recommended all its Bay Area employees in the US to work from home. The latest precautions come after San Francisco announced its first two coronavirus cases on Thursday.

Facebook has also shut its Seattle office until Monday after one of its contractors was confirmed to be infected with the virus. The infected contractor last visited the Facebook office on February 21. King County health officials said all Facebook sites should work from home until March 31.

Twitter shut its Seattle office for a 'deep clean' after an employee developed COVID-19 like symptoms though final result was still awaited.

"A Seattle-based employee has been advised by doctor about likely COVID-19, though still awaiting the final testing," Twitter said in a tweet on Friday.

"While the employee has not been at a Twitter office for several weeks and hasn't been in contact w/others, we're closing our Seattle office to deep clean," the company added.

According to The Seattle Times, at least 14 people have died due to COVID-19 in Washington State till date.

Amazon, Microsoft, Google and Facebook have advised their employees in Washington State to work from home.

Apple has reportedly suggested its employees at California campuses to work from home as an "extra precaution" while new coronavirus cases spread on the west coast in the US, especially Seattle area.

Apple's flagship developers' conference WWDC 2020 in June is also at the risk of getting cancelled as the Santa Clara public health department has warned against large public gatherings. The event draws nearly 5,000 developers from across the world.

The US death toll from the new coronavirus has climbed to 14, according to Johns Hopkins' tracker, with 329 cases reported across the country.

Beijing, May 24: The Chinese virology institute in the city where COVID-19 first emerged has three live strains of bat coronavirus on-site, but none match the new contagion wreaking chaos across the world, its director has said.

Scientists think COVID-19 -- which first emerged in Wuhan and has killed some 340,000 people worldwide -- originated in bats and could have been transmitted to people via another mammal.

But the director of the Wuhan Institute of Virology told state broadcaster CGTN that claims made by US President Donald Trump and others that the virus could have leaked from the facility were "pure fabrication".

"Now we have three strains of live viruses... But their highest similarity to SARS-CoV-2 only reaches 79.8 percent," she said, referring to the coronavirus strain that causes COVID-19.

US demands immediate start to WHO review

The United States called on the World Health Organisation on Friday to begin working immediately on investigating the source of the novel coronavirus, as well as its handling of the response to the pandemic.

One of their research teams, led by Professor Shi Zhengli, has been researching bat coronaviruses since 2004 and focused on the "source tracing of SARS", the strain behind another virus outbreak nearly two decades ago.

"We know that the whole genome of SARS-CoV-2 is only 80 percent similar to that of SARS. It's an obvious difference," she said.

"So, in Professor Shi's past research, they didn't pay attention to such viruses which are less similar to the SARS virus."

Conspiracy rumours that the biosafety lab was involved in the outbreak swirled online for months before Trump and US Secretary of State Mike Pompeo brought the theory into the mainstream by claiming that there is evidence the pathogen came from the institute.

The lab has said it received samples of the then-unknown virus on December 30, determined the viral genome sequence on January 2 and submitted information on the pathogen to the WHO on January 11.

Wang said in the interview that before it received samples in December, their team had never "encountered, researched or kept the virus."

"In fact, like everyone else, we didn't even know the virus existed," she said. "How could it have leaked from our lab when we never had it?"

The World Health Organization said Washington had offered no evidence to support the "speculative" claims.

In an interview with Scientific American, Shi said the SARS-CoV-2 genome sequence did not match any of the bat coronaviruses her laboratory had previously collected and studied.
