What is Global Warming and is it happening on the Earth?

Answer 1

Global warming is an observed increase in the average temperature of the Earth's atmosphere and oceans. The average global temperature has increased by around 0.75 degrees Celsius since the start of the Industrial Age. Part of this increase may be due to natural processes, and would have occurred independently of human activity. However, the consensus of most climate scientists is that global warming is substantially the result of human activities. They say that global warming is being caused by an enhanced greenhouse effect, resulting from an increase in atmospheric concentrations of greenhouse gases.

Gases that contribute to global warming include carbon dioxide, methane, nitrous oxides, chlorofluorocarbons (CFCs), and halocarbons (the replacements for CFCs). The carbon dioxide emissions are primarily from the use of fossil fuels for energy and from deforestation.

Global warming is real and is happening to the earth. Governments and individuals around the world are becoming alarmed at the potential harm that can result from global warming, and are taking action to reduce our carbon emissions.

Answer 2

Global warming is the trapping of the suns heat inside earths atmosphere, causing the heating of earth and the melting of ice caps.

It is caused by burning fossil fuels and deforestation, both of which mean that there is more carbon dioxide added to the greenhouse gases in the atmosphere.

Answer 3

global warming is real
