Ozone hole prediction
Ozone hole prediction. Computer model showing Antarctic ozone levels from 1974 to 2054 if chlorofluorocarbons (CFCs), the chemicals widely blamed for destroying ozone, had not been banned worldwide in 1989. The image shows the ozone levels each summer, from most concentrated (red) through to the least (yellow, green, light blue and violet being near zero). The model increases emissions of CFCs each year by 3 percent. 1974 still represents a normal ozone level but by 1994 a large hole develops. By the year 2054, the ozone level is close to zero across most of the southern hemisphere. Stratospheric ozone prevents excess ultraviolet radiation reaching the surface and harming living organisms

EDITORS COMMENTS
This print from Science Photo Library showcases a computer model's prediction of the ozone hole if chlorofluorocarbons (CFCs) had not been banned worldwide in 1989. The image vividly displays Antarctic ozone levels from 1974 to 2054, illustrating the devastating consequences of CFC emissions on our planet's protective layer. Starting with a normal ozone level in 1974, the model reveals a disheartening progression. By 1994, a substantial hole emerges in the ozone layer, signaling the detrimental impact of unchecked CFC usage. As time progresses towards 2054, it becomes evident that without intervention, our southern hemisphere would face an alarming depletion of this vital shield against harmful ultraviolet radiation. The color gradient employed in this visual representation effectively communicates the severity of ozone thinning. From concentrated red areas denoting maximum protection to yellow and green regions indicating decreasing levels, all the way down to light blue and violet signifying near-zero protection - it is clear that urgent action was necessary to prevent such a dire scenario. Stratospheric ozone plays an essential role in safeguarding life on Earth by preventing excessive ultraviolet radiation from reaching living organisms' surfaces. This thought-provoking image serves as a stark reminder of how human activities can have far-reaching consequences for our planet's delicate balance. It also highlights the significance of international agreements like the Montreal Protocol which aimed at reducing CFC emissions and protecting our atmosphere. Through scientific simulations like these, we gain valuable insights into potential future scenarios and are reminded of our responsibility to preserve and protect our environment for generations to come.
