Evaluating Global Warming Trends Using TOPSIS An Analysis of Global Surface Air Temperatures (2014–2016)

On the basis of five datasets of historical observational records of surface temperature, we present a study of the worldwide annual mean surface temperature anomaly in 2014, 2015, and 2016. These gases cause an increase in global temperatures by trapping heat in the Earth's atmosphere, a process known as the greenhouse effect. The consequences of global warming are wide-ranging and can have severe impacts on both human societies and natural ecosystems. Increased heat waves, droughts, and wildfires can all be brought on by rising temperatures, posing dangers to agriculture, human health, and water supplies. Changes in precipitation patterns can result in more frequent and intense storms, floods, and hurricanes, further threatening communities and infrastructure. In addition to extreme weather events, global warming can disrupt ecosystems and biodiversity. Many species are experiencing shifts in their habitats, altered migration patterns, and changes in their life cycles. Sea levels may rise as a result of glaciers and polar ice caps melting as a result of rising temperatures. This poses a significant threat to coastal regions, increasing the risk of flooding and erosion, and potentially displacing millions of people. Reducing greenhouse gas emissions is crucial for preventing global warming. Many tactics can be used to accomplish this. Switching to sustainable energy sources like solar and wind power, can help reduce carbon dioxide emissions from fossil fuel combustion. Improving energy efficiency in industries, transportation, and buildings can also contribute to emission reductions. Another critical aspect is addressing deforestation and promoting sustainable land management practices. A portion of the heat radiation can be trapped and re-emitted by greenhouse gases like carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and chlorofluorocarbons (CFCs) in the Earth's atmosphere, preventing it from escaping into space. Global warming is the process by which this phenomena causes an increase in the average surface temperature of the Earth. Infrared (IR) radiation is produced when solar radiation strikes the Earth's surface and is absorbed before being reemitted as thermal radiation. Greenhouse gases, particularly CO2 and CH4, are transparent to solar radiation that enters the atmosphere but absorb some of the IR radiation that leaves the atmosphere. Similar to how a greenhouse retains heat inside, this absorption and re-emission process traps heat in the atmosphere. The greenhouse effect has been exacerbated by the increased atmospheric greenhouse gas concentrations brought on by human activity, particularly the burning of fossil fuels, deforestation, and industrial operations. This has resulted in an enhanced trapping of heat and an overall rise in global temperatures. Utilizing the remaining four datasets, similar outcomes were attained. The longer-term warming trend and the bigger contribution from the DM component suggest that warmer years like 2014-2016 may occur more frequently in the near future. We draw the conclusion that the alleged warming hiatus has ended.
