How Does Carbon Dioxide Affect Global Warming

Carbon dioxide (CO2) has long been recognised as one of the main contributors to global warming. With such an expansive role in the climate change crisis, it is important to gain an understanding of how exactly carbon dioxide affects the planet.
The primary source of CO2 is through the burning of different forms of fossil fuels that have been stored for thousands of years below the earth’s surface. This process releases large amounts of carbon dioxide into the atmosphere, which then traps heat from the sun, causing earth temperatures to increase. Carbon dioxide is a greenhouse gas, meaning that it is able to absorb and trap heat in the atmosphere from the sun’s rays. This process is known as the ‘greenhouse effect’. Carbon dioxide is particularly effective at absorbing and trapping solar energy because it contains two oxygen atoms bonded to a single carbon molecule.
The level of carbon dioxide in the atmosphere is steadily increasing due to burning of fossil fuels, deforestation and other human activities. The estimated atmospheric CO2 levels, now around 410 parts per million (ppm) is much higher that pre-industrial times where it was assumed to be 280 ppm. This level has been steadily climbing and is projected to continue to do so in the coming years, due to the continued burning of fossil fuels and other human activities.
Carbon dioxide has several effects on the environment, aside from its role in raising global temperatures. One of the more noticeable effects of CO2 on ecosystems is its direct impact on ocean and freshwater ecosystems, particularly through ocean acidification. When CO2 combines with water in the ocean, it forms a carbonic connection,create a weak acid. This acidity has been shown to have damaging effects on marine communities and to endanger already fragile ecosystems, such as coral reefs.
The impact of carbon dioxide on global warming is widely accepted, with the World Meteorological Organisation (WMO) stating that the ‘greenhouse effect’ is the primary cause of the current warming trend on earth. The WMO also notes that carbon dioxide is the most significant contributor to human-induced global warming. It is estimated that since the pre-industrial era, where CO2 levels were assumed to be approx. 280 ppm, the temperature rise of our planet has been 1.1°C.
As humanity works towards stem the ever-growing climate change crisis, it is important to consider the role of carbon dioxide and how to mitigate its increasing presence in the atmosphere. The continued burning of fossil fuels and other activities that produce CO2 must be minimized in order to ensure a sustainable future for generations to come. Conservation and energy efficiency measures, such as energy-saving devices, can help reduce the build up of carbon dioxide. Additionally, renewable energy methods like solar, wind and hydropower can provide alternative sources of energy to replace those that are derived from fossil fuels. Carbon dioxide capture and storage technology has also been proposed as a potential solution to reducing atmospheric CO2 levels, however, the efficacy and cost benefits of this approach is still being discussed.
The impacts of carbon dioxide on global warming are indisputable and must be taken seriously if humanity hopes to avert the looming climate change crisis. Harnessing natural energy sources and introducing conservation and energy efficiency measures are just some of the practical solutions that need to be taken up in order to mitigate the dangers posed by increasing CO2. Without mass-scale action, it is likely humans will continue to carelessly pump significant amounts of carbon dioxide into the atmosphere, with incredibly damaging effects on our planet.
