Question

Whαt is Globαl Wαrming??​

Answer 1

Answer

The term Global Warming refers to a gradual increase in the overall temperature of the earth's atmosphere. Global warming is caused by the increase of greenhouse gases such as carbon-di-oxide, methane, water vapour, CFCs which are responsible for the heat retention ability of the atmosphere.

Humans cause climate change. Scientists agree that global warming is caused mainly by human activity. Specifically, the evidence shows that certain heat-trapping gases, such as carbon dioxide, are warming the world—and that we release those gases when we burn fossil fuels like coal, oil, and gas

Global warming is the long-term heating of Earth's climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth's atmosphere.
