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.

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.

Karachi, May 29: Investigators and rescue officials have found around Rs 3 crore in cash in the wreckage of the Pakistan International Airlines' aircraft that crashed wth 99 people on board, killing 97 people, including nine children.

Flight PK-8303 from Lahore to Karachi crashed in a residential area near Karachi International Airport on Friday, with only two passengers miraculously surviving the crash.

Investigators and rescue officials have found currencies of different countries and denominations worth around Rs 30 million from the aircraft's wreckage, an official said on Thursday.

"An investigation has been ordered into how such a huge amount of cash got through airport security and baggage scanners and found its way into the ill-fated flight," the official said.

He said that the amount was recovered from two bags in the wreckage.

"The process of identifying the bodies and their luggage which will be handed over to their families and relatives is going on," he said.

A total of 97 people including the aircraft crew died in the crash, one of the most catastrophic aviation disasters in Pakistan's history.

A government official said on Thursday that the identification of 47 bodies had been completed, while 43 bodies were handed over for burial.

Friday's accident was the first major aircraft crash in Pakistan after December 7, 2016 when a PIA ATR-42 aircraft from Chitral to Islamabad crashed midway. The crash claimed the lives of all 48 passengers and crew, including singer-cum-evangelist Junaid Jamshed.

Washington, Jun 26: The United States reported more than 39,000 new coronavirus cases on Thursday, its highest-ever single-day count as the government relaxed restrictions and is downplaying the threat of the deadly virus.

According to the Washington Post, experts believe there is a troubling lack of consistent, unified messaging from President Donald Trump and Vice President Mike Pence. They have downplayed the danger and denigrated effective disease defences such as mask-wearing, testing, and social distancing.

Churches, beaches, and bars are filling up with people and so are hospital beds, the report said.

The counties home to Dallas, Phoenix, and Tampa all reported record-high averages on at least 15 straight days in June.

The hardest-hit states are California, Texas, Florida and those that thought they had the virus under control, like Utah and Oregon.

"I think the politicians are in denial," said Kami Kim, director of the Division of Infectious Disease and International Medicine at the University of South Florida.

The chief of the Division of Pediatric Infectious Diseases at the University of Utah Health, Andrew T. Pavia, is of the view that the push to reopen quickly even as cases climb sends a dangerous and inaccurate message.

"On the one hand, you get messages from politicians and the business community that we have to go, go, go and open up," he said. "On the other hand, you're seeing epidemiological indicators that we still have to be very careful."

"It's cognitive dissonance," he added.

The Trump administration has tried to downplay the rising number. Pence called concerns about another surge of infections "overblown," the product of media "fearmongering."

Some governors have followed the administration's lead, blaming rising caseloads on more testing.

Testifying before a congressional committee this week, Anthony S. Fauci, the nation's top infectious-diseases expert, said the new cases were "a disturbing surge" spurred by community transmission rather than testing.

"That's something I'm really quite concerned about," Fauci said. "A couple of days ago, there were 30,000 new infections. That's very disturbing to me."

Several states like Arizona, Arkansas, the Carolinas, Mississippi, Tennessee, Texas and Utah have recently reported new highs in the number of coronavirus patients hospitalized.

"We're seeing a 40 per cent increase in the last two weeks in hospitalizations," said Dallas County Judge Clay Jenkins (D), the jurisdiction's top elected official. "We're by far at our record numbers, and we're at record numbers in north Texas. Houston is at a record, the state is at a record." The Texas Medical Center in Houston, a massive medical complex, reported Thursday that 100 per cent of the beds in its intensive care unit are occupied.
