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, Jan 21: The Chinese official investigating a pneumonia outbreak stemming from a new coronavirus said the disease can spread from person to person but can be halted with increased vigilance, as authorities on Tuesday confirmed a fourth death.

Zhong Nanshan said there was no danger of a repeat of the Severe Acute Respiratory Syndrome (SARS) epidemic that killed nearly 800 people globally during a 2002-2003 outbreak, which started in China, as long as precautions were taken.

"It took only two weeks to identify the novel coronavirus," state news agency Xinhua quoted Zhong as saying late on Monday.

The outbreak was still in its early stages and China had good surveillance and quarantine systems to help control it, he added.

The outbreak has spread from the central city of Wuhan to cities including Beijing and Shanghai, with more than 200 cases reported so far. Four cases have been reported outside China - in South Korea, Thailand and Japan.

Australia on Tuesday said it would screen passengers on flights from Wuhan amid rising concerns that the virus will spread globally as Chinese travellers take flights abroad for the Lunar New Year holiday starting this week.

Authorities around the globe, including in the United States and many Asian countries, have stepped up screening of travellers from Wuhan.

Chinese authorities confirmed a total of 217 cases of the virus in China as of 6 p.m. (1000 GMT) on Monday, state television reported, 198 of which were in Wuhan.

A fourth person died on Jan. 19, the Wuhan Municipal Health Commission said. The 89-year-old man, who had underlying health diseases including coronary heart disease, developed symptoms on Jan. 13 and was admitted to hospital five days later, it added.

Zhong, who is renowned in China for his work fighting SARS in 2003, confirmed that the virus can pass from person-to-person.

Fifteen medical workers in Wuhan had been diagnosed with pneumonia, with one other suspected case, the Wuhan Municipal Health Commission said. Of the infected staff, one was in critical condition.

In Shanghai, officials on Tuesday confirmed a second case involving a 35-year-man who had visited Wuhan in early January, and said they were monitoring four other suspected cases.

The virus causes a type of pneumonia and belongs to the same family of coronaviruses as SARS. Symptoms include fever and difficulty in breathing, which are similar to many other respiratory diseases and pose complications for screening efforts.

The World Health Organisation (WHO) said on Monday an animal source appeared most likely to be the primary origin of the outbreak and that some "limited human-to-human transmission" occurred between close contacts.

The Geneva-based U.N. agency convened an emergency committee for Wednesday to assess whether the outbreak constitutes an international health emergency and what measures should be taken to manage it.

So far, the WHO has not recommended trade or travel restrictions, but a panel of independent experts could do so or make other recommendations to limit spread.

Geneva, Jun 24: The global cumulative count of confirmed coronavirus cases is approaching nine million, with 133,326 cases recorded over the past day, the World Health Organisation (WHO) said in its daily situation report on Tuesday.

Over the past 24 hours, 3,847 people died from COVID-19 worldwide, taking the cumulative death toll to 469,587 fatalities, according to the report.

The global case total has now reached 8,993,659.

The Americas still account for the majority of cases and deaths -- 4.4 million and 224,207, respectively.

The United States remains the country with the highest count of cases and fatalities -- 2.3 million and 119,761, respectively.

Islamabad, Jul 3: The US embassy here in a statement on Friday said the Trump administration through the US Agency for International Development (USAID) “donated a shipment of 100 brand-new, state-of-the-art ventilators” to Pakistan.

The ventilators arrived in Karachi on July 2 and will be sent to hospitals across Pakistan.

“This donation delivers on President Donald Trump’s generous offer of these critically-needed supplies and supports Pakistan’s urgent response to the pandemic,” the embassy said.

Made in America, the ventilators are valued at about $3 million and reflect the latest in cutting-edge medical design and technology, it said.

They are compact, easily deployable, and will enable Pakistan to more effectively treat patients suffering from Covid-19.

The US-Pakistan health partnership to curb the spread of the novel coronavirus is helping to improve and expand laboratory testing, disease monitoring, case tracking, infection prevention and control and patient care, the embassy said.

The US has contributed nearly $27 million in new funding so far to this vital partnership that is growing every day. "We are also thankful for Pakistan's contribution of medical supplies to help fight coronavirus in the US," the embassy said in the statement.

Ambassador Paul Jones said, “The US stands with Pakistan in its fight against the coronavirus. These American-made ventilators will help Pakistani patients in the most acute need of medical care."

The announcement comes days after Pakistan said it had started producing locally designed ventilators.

Pakistan reported 78 more deaths from the coronavirus in the past 24 hours, raising virus-related fatalities to 4,551 while the total number of confirmed cases has increased to 221,896.

On Friday, the health authorities said 1,13,623 persons have recovered from the coronavirus, surpassing the number of active Covid-19 infections in the country for the first time.
