Topic > Climate Change and Carbon Dioxide (CO2) - 1243

Since the Industrial Revolution, scientists have documented an increasing trend in atmospheric carbon dioxide (CO2), the major greenhouse gas. This observation was of great environmental concern in light of the potentially devastating effects of climate change on ecosystems and human survival. Recent studies by scientists led by Wei-Jun Cai have served to highlight this fact, demonstrating that the Arctic region and the globe are facing a serious climate challenge due to the continued melting of sea ice in the Arctic Ocean. This research indicated that the primary concern is the increasing absorption of heat as deeper layers of ocean water are exposed to sunlight, as well as the possible loss of white ice reflectivity, or albedo (An ice-free Arctic ocean does not will absorb more CO2, nd). This article discusses recent observations that the Arctic Ocean basin does not have an indefinite capacity to continue to serve as a CO2 sink when conditions are ice-free due to rising warmer temperatures. It is worth noting that the sensitivity to climate change in the Arctic is considered the highest on the Earth's surface. Additionally, the region experiences more pronounced acidification than any other ocean. Recent decades have seen the Arctic Ocean experience a steady increase in the rate of sea ice melt. According to Cai et al. (2010), this occurred above all in light of the indications of the three summers from 2007 to 2009. The recent research by Cai et al. it was built on the assumption that, under ice-free conditions in the Arctic Ocean, more and more CO2 would be absorbed by the atmosphere. Therefore, the research investigates the impact of melting sea ice on the CO2 concentration on surface water of Ar......middle of paper......temperatures will continue to cause ice melt in summer . As a result, the partial pressure of carbon dioxide in surface water will continue to increase, further reducing the CO2 sink's ability to absorb more CO2. The high-resolution survey also highlights the fact that the future will see an increase in air-to-sea CO2 flux. This is due to the exposure of a greater surface area of ​​sea water and the extended periods in which the surface of the Arctic Ocean will be subject to ice-free conditions. While this is expected, the ability of the CO2 sink in the Arctic Ocean to continue absorbing CO2 is expected to weaken due to the equilibration of surface water pCO2 with the atmosphere. The survey highlights four main factors that facilitate this balance. These include low CO2 fixation, surface warming, shallow mixed layer depth, and strong surface water stratification (Cai, et al.., 2010).
