<ul><li>A recent study suggests that emissions from expired satellites falling to Earth and burning up will have significant implications for ozone hole recovery and climate change.</li><li>With the number of satellites expected to increase to over 60,000 by 2040, the release of pollutants like aerosolised aluminium during satellite disposal could impact the Earth's atmosphere.</li><li>Researchers simulated the effects of an annual release of 10,000 tonnes of aluminium oxide by 2040 to understand the potential impact on the environment.</li><li>Results show that the accumulation of re-entry materials could lead to temperature anomalies, reduction in wind speeds, and ozone depletion, affecting ozone hole recovery efforts.</li></ul>
