Which of the following best describes global warming?

The characterization of global warming as a gradual elevation of the Earth's temperature is accurate because it refers to the long-term trend of increasing average temperatures across the planet due to the accumulation of greenhouse gases in the atmosphere. This phenomenon results from human activities such as burning fossil fuels, deforestation, and industrial processes, which increase the concentration of carbon dioxide and other greenhouse gases, trapping heat and leading to the warming effect.

This warming influences various aspects of the Earth's climate system, including weather patterns, sea levels, and ecosystems. Observations over multiple decades show consistent trends in rising temperatures, confirming the gradual nature of this process rather than rapid shifts or fluctuations in climate. Understanding global warming in this context is crucial for addressing its broader impacts on the environment and society.
