Global warming is an issue that has been at the forefront of public concern for many years now, and it continues to be a pressing problem in today’s world. The term refers to the gradual increase in the Earth’s surface temperature, caused by the accumulation of greenhouse gases in the atmosphere. These gases trap heat from the sun and prevent it from escaping into space, leading to a rise in global temperatures.
Global warming from the beginning
The concept of global warming has been around for over a century, but it wasn’t until the 1980s that it gained widespread attention as a pressing issue. Here’s a brief history of global warming:
- 1824: French mathematician Joseph Fourier first proposed the idea that Earth’s atmosphere could act as a “blanket” to trap heat.
- 1861: British physicist John Tyndall identified greenhouse gases and their role in trapping heat.
- 1896: Swedish chemist Svante Arrhenius published a paper suggesting that the burning of fossil fuels could lead to a rise in global temperatures.
- 1930s-1960s: Scientists began to measure atmospheric carbon dioxide levels and noticed a steady increase.
- 1970s: Concerns about global cooling due to aerosol pollution gave way to concerns about global warming.
- 1980s: The issue of global warming gained widespread attention, with the publication of reports from the United Nations and other organizations.
- 1992: The United Nations Framework Convention on Climate Change was signed, calling for international cooperation to reduce greenhouse gas emissions.
- 2007: The Intergovernmental Panel on Climate Change released a report stating that global warming is “unequivocal” and caused by human activities.
- 2015: The Paris Agreement was signed, setting a goal to limit global warming to below 2 degrees Celsius above pre-industrial levels.
Today, global warming continues to be a pressing issue, with rising global temperatures and more frequent and severe weather events. It is essential that we take action to reduce our greenhouse gas emissions and mitigate the impacts of global warming on our planet.

The impact of global warming
It is being felt across the planet, with more frequent and severe weather events such as hurricanes, droughts, wildfires, and floods. The melting of polar ice caps is leading to rising sea levels, which threatens low-lying areas and coastal cities. Biodiversity loss is also a significant concern, with rising temperatures and extreme weather events leading to habitat destruction and species extinction.
The scientific consensus is clear: global warming is caused by human activities, particularly the burning of fossil fuels such as coal, oil, and gas. These activities release large amounts of greenhouse gases into the atmosphere, contributing to the overall warming effect. It is essential that we take action to reduce our greenhouse gas emissions and mitigate the impact of global warming on our planet.

The global warming actions
There are many solutions available to address global warming, including transitioning to renewable energy sources, such as solar and wind power, improving energy efficiency, and reducing our carbon footprint through lifestyle changes, such as using public transportation or eating a plant-based diet. It is also crucial to raise awareness about the issue and engage in policy and advocacy efforts to pressure governments and corporations to take action.
- Transition to renewable energy sources: We can reduce our dependence on fossil fuels by transitioning to renewable energy sources such as solar, wind, and hydropower. This can be done at both the individual and governmental level.
- Improve energy efficiency: We can reduce our energy consumption by improving energy efficiency in our homes, offices, and transportation systems. This can include things like upgrading to energy-efficient appliances and light bulbs, and using public transportation or carpooling instead of driving alone.
- Reduce our carbon footprint: We can reduce our carbon footprint by making small changes to our daily habits, such as eating a plant-based diet, reducing food waste, and buying locally sourced and sustainably produced products.
- Engage in advocacy and policy efforts: We can pressure governments and corporations to take action on global warming by engaging in policy and advocacy efforts, such as contacting elected officials and supporting climate-friendly policies.
- Support reforestation efforts: Trees absorb carbon dioxide and provide a natural way to remove carbon from the atmosphere. Supporting reforestation efforts and protecting existing forests can help mitigate the impact of global warming.
- Educate others: It is essential to raise awareness about global warming and its impact on our planet. We can educate others about the issue and encourage them to take action in their own lives.
In conclusion, global warming is a critical issue that requires urgent action from individuals, organisations, and governments worldwide. By taking action to reduce our greenhouse gas emissions and mitigate the impact of global warming, we can help protect our planet and ensure a sustainable future for generations to come.
