What is global warming?

Global warming, on the other hand, refers specifically to the overall increase in the earth's temperature, which can in turn affect global climate patterns

The three main indicators of global warming are temperature,precipitation, and sea level.

Global warming is one of the most controversial science issues of the 21st century, challenging the very structure of our global society. The problem is that global warming is not just a scientific concern, but encompasses economics, sociology, geopolitics, local politics, and individuals’ choice of lifestyle. Global warming is caused by the massive increase of greenhouse gases, such as carbon dioxide, in the atmosphere, resulting from the burning of fossil fuels and
deforestation.
