The atmosphere is a mixture of gases that surrounds the Earth. It helps make life possible by providing us with air to breathe, shielding us from harmful ultraviolet (UV) radiation coming from the Sun, trapping heat to warm the planet, and preventing extreme temperature differences between day and night. But climate change is affecting our atmosphere.
A warming atmosphere affects more than just air temperatures: while heat waves and droughts are becoming more common and intense, rainstorms are also becoming more powerful, sometimes provoking dangerous floods. Our atmosphere is made up of many different gases. The most common gases are nitrogen, oxygen and argon. But, the exact amount of each gas is always changing.
Since the industrial revolution, humans have caused a big change in the composition of the atmosphere and significantly increased the amount of greenhouse gases in the atmosphere. These gases cause the atmosphere to trap more heat – like a greenhouse – leading to long-term changes in our climate. The most well-known greenhouse gas is carbon dioxide.
We are looking at how atmospheric composition will change in the future, with particular focus on the stratosphere, the second layer of the earth’s atmosphere. We are also looking at how changes in the stratosphere will affect the troposphere, the first layer of the earth’s atmosphere and the air that we breathe.
Climate change can lead to various changes in the atmosphere, which in turn contribute to shifts in weather patterns and long-term climatic trends. Some key changes include:
Increased greenhouse gas concentrations: Climate change is primarily driven by the accumulation of greenhouse gases such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) in the atmosphere. Human activities, such as burning fossil fuels and deforestation, have significantly increased the levels of these gases, trapping more heat in the atmosphere and causing global temperatures to rise.
Changes in precipitation patterns: Climate change can alter patterns of rainfall and snowfall, leading to more intense and frequent extreme weather events such as storms, hurricanes, droughts, and floods. Some regions may experience increased rainfall and flooding, while others may face prolonged dry spells and water shortages.
Rising temperatures: One of the most visible effects of climate change is the overall warming of the planet. Average global temperatures have been steadily increasing over the past century, leading to changes in weather patterns, melting ice caps and glaciers, and rising sea levels.
Changes in atmospheric circulation: Climate change can disrupt atmospheric circulation patterns, such as the jet stream, leading to shifts in weather patterns and the distribution of precipitation. These changes can have significant impacts on agriculture, water resources, and ecosystems.
Increased frequency of heatwaves: Climate change is associated with more frequent and intense heatwaves, which can have serious health implications, especially for vulnerable populations such as the elderly, children, and people with pre-existing health conditions.
Ocean acidification: The increased concentration of CO2 in the atmosphere also leads to higher levels of CO2 being absorbed by the oceans, causing ocean acidification. This can have detrimental effects on marine ecosystems, including coral reefs, shellfish, and other marine organisms.
Overall, climate change is causing significant changes in the composition and behavior of Earth’s atmosphere, with far-reaching consequences for both human societies and natural ecosystems.
