The impact of humans on global warming has been hotly debated for decades, with scientific evidence pointing to the undeniable role we have to play. To understand the issue and the consequences for our planet, it’s essential to look at the causes and effects of global warming, and how our actions have shaped the current environment.
One of the main causes of global warming is the emission of greenhouse gases (GHGs) from human activities, such as burning fossil fuels, industrial production and deforestation. These GHGs trap heat within the atmosphere, which acts as a blanket, resulting in a gradual increase in the Earth’s temperature. Although this type of climate change is natural, it has been exacerbated by humans and consequently, it is known as anthropogenic (man-made) global warming. It is this form of human-driven climate change that is causing serious concern.
The Intergovernmental Panel on Climate Change (IPCC) has shown that in the past two centuries, it has been the human activity that has contributed the most to global warming and its devastating consequences. By burning fossil fuels and deforesting, the amount of GHGs have increased dramatically in the atmosphere. As a result of this, the average temperature of the planet’s surface has risen by1.5C since pre-industrial times and is likely to rise further if emissions continue to increase. This rise in temperature has already had detrimental effects on the environment, from melting ice caps to glacial retreats and rising sea levels.
It is therefore of paramount importance to realize our responsibility for the climate crisis and to begin taking steps to reduce emissions. This means reducing energy consumption, investing in renewable energy sources and start engaging in sustainable practices whenever possible. Although this may seem daunting, individuals can make a huge difference by doing relatively simple things, such reducing personal vehicle usage and opting for public transportation, recycling and reusing products, and reducing their consumption of animal products.
We must also recognize that the climate crisis cannot be solved alone by individuals. What is needed is a collective effort from all sectors, including governments, businesses and corporations, to make a real impact. Governments must commit to creating progressive climate change policies and provide support for renewable energy research and development. Businesses must also make the switch to renewables, while corporations should focus on using sustainable practices.
In conclusion, it is evident that human activities have had an undeniable impact on global warming. To tackle this immense challenge, it is necessary to be aware of our individual and collective responsibilities and to act accordingly. This involves shifting the way we currently interact with the environment, but the potential rewards of doing so make it more than worthwhile.
