For decades, debate has raged as to whether Global Warming is real and what, if anything, can be done about it. Evidence of Global Warming has been studied for many years, although there is no definitive answer of whether it is occurring or not. While there is convincing evidence of the impact of human activities on our climate, including direct observations made over the last century, scientific studies, and analysis of atmospheric gases, there is still disagreement on the nature and extent of this phenomenon. This article examines the evidence of Global Warming and weighs the positive and negative implications of it.
The primary argument in favor of Global Warming being real lies in the data. Direct evidence of the warming of the planet’s surface has been recorded since the 1880s, generally increasing at a rate of around 0.8 – 1.2 degrees Celsius. This is sufficient to conclude that the Earth’s climate is changing. Supporting this data are scientific models which examine how changes in greenhouse gases in the atmosphere will impact our climate. These models indicate that levels of greenhouse gases are increasing, which is causing a rise in temperature.
Furthermore, analysis of atmospheric gases provides evidence of a change in the climate. For example, data from the World Meteorological Organization (WMO) shows that the atmospheric concentration of carbon dioxide in 2017 was 405 parts per million (ppm), well above the pre-industrial value of 280 ppm. This data indicates that human activities, such as burning fossil fuels, are releasing more greenhouse gases into the atmosphere and thus having an effect on climate change.
Supporters of Global Warming are eager to discuss positive implications of this phenomenon. They suggest that the evidence of a gradual rise in temperature due to carbon emissions can be used to reduce emissions and thus reduce the affects of Global Warming. Other positive effects cited include improved crop yields due to increased temperatures in some areas, increased rainfall in some places, and the potential for geothermal energy to become a more viable option for power generation.
The primary counter argument that Global Warming is not real, comes from those who dispute the evidence presented by the data. This group questions the accuracy of the measurements and analysis methods used, as well as the validity of the scientific models. They also suggest that the impacts of human activities on the climate are minimal and that natural factors such as volcanic activity and solar winds are more responsible for the changes in climate. These arguments are difficult to refute without further data and evidence.
On the other hand, the effects of Global Warming can also be seen in a negative light. An increase in global temperatures can cause droughts, or episodes of extreme heat, as well as an increase in sea level due to the melting of polar ice caps. This would lead to the displacement of countless people who live in coastal areas. Additionally, an increased frequency in extreme weather, such as floods and hurricanes, could lead to widespread destruction and loss of life.
The data presented here shows that Global Warming is likely occurring, with evidence from many sources indicating that it is likely caused by human activities. However, there is still disagreement on the nature and extent of this phenomenon and further data and analysis will be required to reach a conclusive answer. It is evident that regardless of its origin, Global Warming has both potential positive and negative implications for our planet and further research and discussion is needed.
