What is meant by global warming?

Global warming refers to the long-term increase in Earth's average surface temperature due to the accumulation of greenhouse gases in the atmosphere. These gases, such as carbon dioxide, methane, and nitrous oxide, trap heat from the sun, leading to a greenhouse effect that raises global temperatures. This warming process has been significantly accelerated by human activities, predominantly from the burning of fossil fuels, deforestation, and industrial processes.

The process of global warming has far-reaching effects on climate patterns, weather events, and ecosystems, contributing to issues like rising sea levels, extreme weather events, and shifts in wildlife populations and habitats. Understanding the role of greenhouse gas accumulation is essential for recognizing the dynamics of climate change and its impact on the planet.
