It is an undisputable fact that global warming is one of the very real, and serious, challenges facing the world today. Fast-accelerating greenhouse gas emissions have put the environment in peril, leading to a rise in temperatures across the globe, increasing levels of extreme weather, and rising sea levels that threaten our established coastal communities. Although the science behind climate change and its primary cause, human activity, are generally clear, there are a variety of factors that contribute to global warming.
First and foremost, the emissions of various greenhouse gases, including carbon dioxide and methane, are a major factor in global warming. A large portion of these emissions are the result of human activities, such as burning fossil fuels and deforestation, which leaves fewer trees to absorb carbon dioxide and balance the environment. Industrialized nations, who often rely heavily on coal and oil, are responsible for the bulk of global greenhouse gas emissions.
Another factor that contributes to global warming is the loss of woodlands and natural ecosystems. By removing these ecosystems, carbon dioxide is no longer absorbed and released into the air. Additionally, more land cover means more solar radiation is reflected back into the atmosphere and no longer absorbed by the vegetation. These two factors combined, create an even greater opportunity for global temperatures to rise.
Finally, increases in agricultural production and livestock farming – both of which require large amounts of land and intensive energy-intensive use of fertilizers and pesticides – are serious contributors to global warming. The burning of these compounds produces nitrous oxide, which is 300 times more potent than carbon dioxide, and is a major contributor to the rise in average global temperatures.
The consequences of global warming are dire and potential solutions cannot be implemented without understanding all of the factors that are causing it in the first place. Research and advanced technologies are necessary to keep this issue under control. By becoming better informed, reducing our reliance on fossil fuels and developing energy solutions that rely on renewable energy sources – such as solar, wind, geothermal, and tidal energy –, fewer emissions of greenhouse gases will be released and global temperatures can be stabilized. Everyone can make a difference, and it is important for us to take action now. Only by working together can we save ourselves from the alarming effects of global warming.
