In her article, “Irreversible climate change due to carbon dioxide emissions,” Susan Solomon and her colleagues express how the human race has such a large impact on the world’s climate change. The paper focuses on how the effects of increases in carbon dioxide on the atmosphere take around a thousand years to be repaired. Human activities were identified as the most prominent cause of the rise in “atmospheric concentrations of key greenhouse gases.” These increases in greenhouse gases, especially carbon dioxide, will result in a wider range of damaging and possibly irreversible climate changes.
Solomon highlights how complicated the multi-step process of carbon dioxide atmospheric extraction can be. The process includes “rapid exchange with the land biosphere and the surface layer of the ocean through air-sea exchange.” Typically, 20% of the added tonnes of carbon dioxide stay in the atmosphere while 80% becomes mixed in with the ocean. Ocean warming is just one quantifiable aspect of climate change. Unlike methane or nitrous oxide, carbon dioxide is the only greenhouse gas whose gases persist over time rather than periodic instances. The graphs below display the amount of carbon dioxide that is “expected to be retained in the atmosphere by the end of the millennium.”
Overall, the main point of Solomon’s article was to highlight how irreversible these small but detrimental gas emissions can be to our climate. Changes in sea levels, changes in precipitation, and changes in atmospheric warming can all be traced back to the increase in CO2 emissions into the atmosphere. Not only are these changes dangerous to the environment, but also play a vital role in the timeline of mankind.
