The ozone layer is still getting thinner, new study finds

The ozone layer is still getting thinner, new study finds

Most scientists figured that the ozone layer would return to its proper form by 2050 or so. But when Ball and his colleagues measured the total amount of ozone in the atmosphere, they found that the overall concentration was about the same as it’s been, despite that measured boost in the upper layer. That discovery led the team to surmise that the lower level of the ozone layer, which lies between 15 and 24 kilometers (9 and 15 miles) above the Earth’s surface, is still getting thinner. The authors note that this part of the layer usually has the highest density of ozone, which shields the planet from ultraviolet rays and other types of radiation.
