Improperly recycled refrigerators not enough to explain rise in ozone-eating gas

Improperly recycled refrigerators not enough to explain rise in ozone-eating gas

Science
May 24 (UPI) -- Despite reports that improperly recycled refrigerators in China could explain a recent uptick in chlorofluorocarbon emissions, NOAA scientist Steve Montzka suggests the new mystery source of CFC-11 remains unaccounted for. Earlier this month, Montzka and his colleagues identified rising levels of CFC-11, a common chlorofluorocarbon, in air samples collected in Hawaii. Emissions had been dropping globally over the last two decades. The rise in CFC-11 concentrations first showed up in 2013, suggesting the chemical's proliferation can be explained by a new source -- a source scientists think is located somewhere in East Asia. Chlorofluorocarbons like CFC-11 were used in a variety products, including refrigerators and air-conditioners, for decades before being phased out beca...
'Urban Ebola' could see cases rise exponentially

'Urban Ebola' could see cases rise exponentially

World
There is a "very high" public health risk from Ebola in the Democratic Republic of the Congo, the World Health Organisation has said.  The health agency has raised its earlier assessment after one patient in a major city was confirmed as having the disease.Although the global risk of an Ebola outbreak remains low, the WHO says the risk to countries neighbouring the Congo is now "moderate".On Thursday, a case was confirmed in Mbandaka - a city of about 1.5 million people.The city lies about 93 miles from Bikoro, a remote area where the current outbreak was announced last week.Now the disease has been reported in a highly populated urban area, it is expected to spread more quickly."The confirmed case in Mbandaka, a large urban centre located on major national and interna...
Mysterious rise in emissions of ozone-damaging chemical

Mysterious rise in emissions of ozone-damaging chemical

Science
Scientists have detected an unexpected rise in atmospheric levels of CFC-11, a chlorofluorocarbon (CFC) highly damaging to the ozone layer.Banned by the Montreal Protocol in 1987, CFC-11 was seen to be declining as expected but that fall has slowed down by 50% since 2012.Researchers say their evidence shows it's likely that new, illegal emissions of CFC-11 are coming from East Asia.These could hamper the recovery of the ozone hole and worsen climate change.CFC-11 is also known as trichlorofluoromethane, and is one of a number of CFCs that were initially developed as refrigerants during the 1930s. They were also used as propellants in aerosol sprays and in solvents. However, it took many decades for scientists to discover that whe...
Household squeeze shows signs of easing as wages rise

Household squeeze shows signs of easing as wages rise

Business
Wages grew by 2.6% in the three months to January while the unemployment rate fell, according to new data. The Office for National Statistics said that earnings growth was slightly higher than the 2.5% rate in the previous period.It adds to evidence that the squeeze on household income may be coming to an end after inflation fell to 2.7% in February.Meanwhile, the unemployment rate ticked lower to 4.3% from 4.4%. A small estimated increase in the number of unemployed people during the quarter did not dent the overall rise in employment over the last year. Matt Hughes, senior statistician at the ONS, said: "Employment and unemployment levels were both up on the quarter, with the employment rate returning to its joint highest ever."He said: "Total earnings growth continues to nudge upwards i...
Researchers see sharp rise in kids' ER visits for allergies: Study

Researchers see sharp rise in kids' ER visits for allergies: Study

Health
March 13 (UPI) -- Children's emergency room visits because of food and other allergies rose 150 percent over seven years, according to a Blue Cross Blue Shield Association report released Tuesday.The insurer's 19th Health of America Report detailed the number of emergency room visits for anaphylaxis from 2010 to 2016, and how many of Blue Cross and Blue Shield's youngest members were diagnosed with an allergy.The study is a collaboration between BCBSA and Blue Health Intelligence from a market-leading claims database. The 36 independent Blue Cross Blue Shield companies insure one in three Americans.The number of children suspected of having an anaphylaxis episode increased 104 percent over seven years, rising from 23 per 10,000 children in 2010 to 47 per 10,000 children in 2016.Allergic re...
