What is the definition of the term ''global warming'' and what are some of its impacts on the planet?

Global warming refers to the gradual increase in the Earth's average surface temperature due to rising levels of greenhouse gases, primarily carbon dioxide, in the atmosphere. The burning of fossil fuels, deforestation, and other human activities contribute to the increase in greenhouse gases, trapping more heat from the sun and causing the planet to warm.

The impacts of global warming on the planet are far-reaching and complex. Some of the most significant impacts include rising sea levels, more frequent and severe heat waves, melting of polar ice caps, changes in precipitation patterns, and an increase in extreme weather events such as hurricanes, floods, and droughts. Global warming also affects ecosystems and biodiversity, leading to habitat loss and changes in species behavior, migration patterns, and distribution. Additionally, global warming can exacerbate existing health problems and cause new ones, such as respiratory illnesses and the spread of infectious diseases.
