Early indications are that the ozone hole may be healing, says one top scientist. The hole in the Earths ozone layer that forms over Antarctica each September grew to about 8.9 million square miles this September before starting to recover, according to scientists from NASA and the National Oceanic and Atmospheric Administration (NOAA) who monitor the annual phenomenon. In 2015 the ozone hole grew to 10.9 million square miles, 2 million square miles larger than this year, before returning to relatively normal summer levels. Its larger size last year was due to colder-than-average temperatures in the stratosphere that amplified the destruction of ozone by sunlight reacting with chlorine and bromine from man-made chemicals, scientists said. In 2016, warmer stratospheric temperatures constrained the growth of the ozone hole. This year we saw an ozone hole that was just below average size, said Paul A. Newman, chief scientist for Earth Sciences at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. What were seeing is consistent with our expectation and our understanding of ozone depletion chemistry and stratospheric weather. At its peak on September 28, the ozone hole extended across an area nearly three times the size of the continental United States. The average area of the hole observed since 1991 has been roughly 10 million square miles.

Some Useful Ideas On Realistic Cataracts Methods
He had an internal medical intern ship at the New York Hospital/Cornell Medical enter. Strong correlations showed up between cataract risk and diet type. By age 65, over 90 percent of people have a cataract and half of the people between the ages of 75 and 85 have lost some vision due to a cataract. Some children will be given eye patches or shields to help prevent itching, injury, and photo phobia sensitivity to light. Congenital cataracts’ childhood cataracts – these may be present when the baby is born, or shortly after birth. Vision problems with cataracts If your vision has become blurry, cloudy or dim, or things you see are not as bright or colourful as they used to be, a cataract may have developed in one or both of your eyes. Sometimes cataracts develop in both eyes at the same time. Although many cataracts are not significant enough to require treatment, surgical removal of cataracts is usually safe and effective, resulting in improvement of vision. Robertson D expert opinion.
