Ozone layer recovery could be delayed by 30 years

Science
Rising global emissions of some chlorine-containing chemicals could slow the progress made in healing the ozone layer.A study found the substances, widely used for paint stripping and in the manufacture of PVC, are increasing much faster than previously thought.Mainly produced in China, these compounds are not currently regulated. Experts say their continued use could set back the closing of the ozone hole by up to 30 years. Scientists reported last year that they had detected the first clear evidence that the thinning of the protective ozone layer was diminishing.

It has progressively helped governments phase out the chlorofluorocarbons and the hydrochlorofluoro...

ECB's Mario Draghi says global recovery is firming up, euro climbs

Finance
European Central Bank President Mario Draghi said Friday the global recovery is improving, but like an increasing number of financial and business leaders, warned about demographic challenges to growth.The euro spiked 1 percent to a high of $ 1.1940, its highest against the U.S. dollar since January 2015 after Draghi's initial remarks."The global recovery is firming up," Draghi said, according to prepared remarks on the European Central Bank website. He noted that in Europe and Japan, "the consolidation of the recovery is at an earlier stage" versus that of the U.S.Draghi also said significant monetary accommodation is still needed and that inflation is not yet converging to the central bank's target. The euro edged off session highs to trade near $ 1.192 after those comments."It would sug...
Unregulated chemicals may be stunting ozone recovery, new study suggests

Unregulated chemicals may be stunting ozone recovery, new study suggests

Science
June 27 (UPI) -- According to new research in England, several unregulated chemicals may be delaying the recovery of the ozone.The depletion of the ozone in the 1970s and 80s was caused by the proliferation of chlorofluorocarbons, chlorine derivatives used in aerosol cans, refrigerators and many other products and appliances. After the 1987 passage of the Montreal Protocol, the first treaty unanimously ratified by all members of the United Nations, CFCs were almost entirely phased out.A number of recent studies have detailed the slow but steady recovery of the ozone layer over the last three decades, but the latest study suggests there is room for improvement.Scientists at the University of Lancaster say atmospheric concentrations of dichloromethane, a short-lived, ozone-depleting substanc...
