There has been an increase in global temperatures over the last century as the Earth has begun to experience global warming or climate change. Atmospheric CO₂ levels have been steadily rising in response to increasing levels of human activities that involve burning of fossil fuels, leading to a buildup of greenhouse gases and ultimately rising global temperatures. So, why is the Earth getting warmer?

What is causing the warming of the Earth?
The primary factor contributing to global warming is increasing levels of greenhouse gases like carbon dioxide (CO₂), water vapor, nitrous oxide and methane which trap heat in the atmosphere. When these gases are emitted into the atmosphere they absorb the heat from the sun and prevent it from escaping the planet, thus leading to increased temperatures on the surface.
The primary cause of this increase in atmospheric CO₂ levels is burning of fossil fuels like coal, oil and gas for energy, industrial activity and transportation, as well as deforestation and loss of natural habitats, and poor agricultural practices. All of these activities release highly reactive gases such as carbon dioxide and methane into the atmosphere, leading to an increase in greenhouse gases and the primary cause of why the Earth is getting warmer.
What are the impacts of global warming?
The impacts of global warming are far-reaching and extend to virtually all parts of the planet, with certain areas most impacted by climate change. Warmer temperatures are leading to more extreme and unpredictable weather events like droughts, floods and storms, as well as rising sea levels. These events cause disruption to both human and natural systems and can even lead to loss of life.
In addition, warmer temperatures cause glaciers and ice to melt, leading to the release of additional greenhouse gases in the form of the so-called “ice-albedo feedback loop”. As glaciers and ice caps melt, they uncover darker surfaces like land and water that absorb more heat from the sun, further increasing temperatures.
Finally, warmer temperatures can disrupt entire ecosystems, causing species to migrate, habitats to change and many species to become threatened or even extinct.
How can we reduce Earth’s warming?
The good news is that there are steps we can take to slow down and even reduce global warming.
The most important step is to reduce our use of fossil fuels. We can start by using renewable energy sources like solar, wind or hydropower instead of burning coal, oil or gas. We can also reduce our reliance on transportation by using public transportation, walking or biking, and by carpooling.
We can also make a difference by reducing our consumption of energy. This includes using energy-efficient appliances, turning off lights when not needed, and reducing our water waste.
Finally, we can also act to reduce global warming by protecting and restoring our natural habitats. This includes conserving existing forests, planting more trees, reducing our consumption of animal products, and practicing sustainable agricultural methods.
Conclusion
Why is the Earth getting warmer? Global warming is a complex and serious issue that has far-reaching impacts on our planet. Fortunately, there are steps that we can all take to reduce our contribution to this global issue and help protect our planet for future generations.
By reducing our dependence on fossil fuels, reducing our energy consumption, and protecting our natural habitats, we can all make a difference and help slow down global warming.
