Global Warming is a Catastrophe that Warrants Immediate Action
Global warming is the phenomenon rise in temperature of the earth’s atmosphere, which is caused by the greenhouse effect (Watson et al. 565). The greenhouse effect is attributed to increased levels of greenhouse gases like carbon dioxide, chlorofluorocarbons, and others. Global warming is a divisive factor because there are those who believe it does not exist, and others state it is an urgent problem. However, evidential signs like climate change, melting of polar ice, rising sea levels, and others act as a reminder of the roaming catastrophe and, therefore, it warrants immediate action.
