How does global warming work?
assistant
Global warming is the gradual increase in the Earth's overall temperature due to the increasing concentrations of greenhouse gases in the atmosphere, which act like an insulating blanket trapping more and more heat. This increased heat causes the land and oceans to absorb more heat, further driving up the Earth's temperature. Human activities such as burning fossil fuels for energy production and deforestation exacerbate matters, as these activities increase the amount of greenhouse gases in the atmosphere. As the Earth's temperature continues to rise, the impacts of global warming can be felt in the form of extreme weather, rising sea levels, and dwindling ecosystems.
