This study draws a new stark link between two major environmental concerns \u2013 the hole in the ozone layer and global warming.<\/p>\n\n\n\n<p>The research team, led by a Lancaster University scientist, reveals that if ozone-destroying chemicals, which most notoriously include CFCs, had been left unchecked then their continued and increased use would have contributed to global air temperatures rising by an additional 2.5\u00b0C by the end of this century.<\/p>\n\n\n\n<p>Their findings, outlined in the paper \u2018<a href=\"https:\/\/www.nature.com\/articles\/s41586-021-03737-3\" target=\"_blank\" rel=\"noreferrer noopener\">The Montreal Protocol protects the terrestrial carbon sink<\/a>\u2019, show that banning CFCs has protected the climate in two ways &#8211; curbing their greenhouse effect and, by protecting the ozone layer, shielding plants from damaging increases in ultraviolet radiation (UV). Critically, this has protected plant\u2019s ability to soak up and lock in carbon dioxide from the atmosphere and so prevented a further acceleration of climate change.<\/p>\n\n\n\n<p>The research team developed a new modelling framework, bringing together data on ozone depletion, plant damage by increased UV, the carbon cycle and climate change. Their novel modelling shows an alternative future of a planet where the use of CFCs continued to grow by around three per cent a year.<\/p>\n\n\n\n<p><strong>Their modelling reveals:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Continued growth in CFCs would have led to a worldwide collapse in the ozone layer by the 2040s.<\/li><li>By 2100 there would have been 60 per cent less ozone above the tropics. This depletion above the tropics would have been worse than was ever observed in the hole that formed above the Antarctic.<\/li><li>By 2050 the strength of the UV from the sun in the mid-latitudes, which includes most of Europe including the UK, the United States and central Asia, would be stronger than the present day tropics.<\/li><\/ul>\n\n\n\n<p>The depleted ozone layer would have seen the planet, and its vegetation, exposed to far more of the sun\u2019s UV.<\/p>\n\n\n\n<p>Plants absorb carbon dioxide (CO<sub>2<\/sub>) through photosynthesis and studies have shown that large increases in UV can restrict plant growth, damaging their tissues, and impairing their ability to undertake photosynthesis. This means the plants absorb less carbon.<\/p>\n\n\n\n<p>Less carbon in vegetation also results in less carbon becoming locked into soils, which is what happens to a lot of plant matter after it dies. All of this would have happened on a global scale.<\/p>\n\n\n\n<p>The researchers\u2019 models show that in a world without the Montreal Protocol the amount of carbon absorbed by plants, trees and soils dramatically plummets over this century. With less carbon in plants and soils, more of it remains in the atmosphere as CO<sub>2<\/sub>.<\/p>\n\n\n\n<p><strong>Overall, by the end of this century without the Montreal Protocol CFC ban:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>There would have been 580 billion tonnes less carbon stored in forests, other vegetation and soils.<\/li><li>There would be an additional 165-215 parts per million of CO<sub>2<\/sub> in the atmosphere, depending on the future scenario of fossil fuel emissions. Compared to today\u2019s 420 parts per million CO<sub>2<\/sub>, this is an additional 40-50%.<\/li><li>The huge amount of additional CO<sub>2 <\/sub>would have contributed to an additional 0.8\u00b0C of warming through its greenhouse effect.<\/li><\/ul>\n\n\n\n<p>Ozone depleting substances, such as CFCs, are also potent greenhouse gases and previous research has shown that their ban prevented their contribution to global warming through their greenhouse effect. By the end of this century, their greenhouse effect alone would have contributed an additional 1.7\u00b0C global warming. This is in addition to the newly quantified 0.8\u00b0C warming, coming from the extra CO<sub>2<\/sub> that would have resulted from damaged vegetation, meaning that temperatures would have risen 2.5\u00b0C overall.<\/p>\n\n\n\n<p><a href=\"https:\/\/www.lancaster.ac.uk\/lec\/about-us\/people\/paul-young\" target=\"_blank\" rel=\"noreferrer noopener\">Dr Paul Young<\/a>, lead author from Lancaster University, said: \u201cOur new modelling tools have allowed us to investigate the scorched Earth that could have resulted without the Montreal Protocol\u2019s ban on ozone depleting substances.<\/p>\n\n\n\n<p>\u201cA world where these chemicals increased and continued to strip away at our protective ozone layer would have been catastrophic for human health, but also for vegetation. The increased UV would have massively stunted the ability of plants to soak up carbon from the atmosphere, meaning higher CO<sub>2<\/sub> levels and more global warming.<\/p>\n\n\n\n<p>\u201cWith our research, we can see that the Montreal Protocol\u2019s successes extend beyond protecting humanity from increased UV to protecting the ability of plants and trees to absorb CO<sub>2<\/sub>. Although we can hope that we never would have reached the catastrophic world as we simulated, it does remind us of the importance of continuing to protect the ozone layer. Entirely conceivable threats to it still exist, such as from unregulated use of CFCs.\u201d<\/p>\n\n\n\n<p>The planet has already seen 1\u00b0C warming from pre-industrial temperatures. Even if we had somehow managed to get to net zero CO<sub>2<\/sub> emissions, the additional 2.5\u00b0C rise would take us to a rise of 3.5\u00b0C. This is far in excess of the 1.5\u00b0C rise above pre-industrial levels that many scientists see as the most global temperatures can rise in order to avoid some of the most damaging effects of climate change.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Dr Chris Huntingford of the UK Centre for Ecology &amp; Hydrology said: \u201cThis analysis reveals a remarkable linkage, via the carbon cycle, between the two global environmental concerns of damage to the ozone layer and global warming.\u201d <a href=\"https:\/\/www.nature.com\/articles\/s41586-021-03737-3\">DOI:
