The main cause of climate change is global warming, which has many negative consequences on physical, biological and human systems, as well as other effects.

Global warming is caused by the greenhouse effect, a natural process by which the atmosphere retains some of the Sun’s heat, allowing the Earth to maintain the necessary conditions to host life. The problem is that daily human activities maximize the greenhouse effect, causing the planet’s temperature to increase even more.

Experts agree that the industrial Revolution was the turning point when emissions of greenhouse effect gases entering the atmosphere began to soar. Moreover, population growth, exploding resource use, increasing energy demand and production, mainly from fossil fuels, all saw the planet enter into what the scientific community have termed the Anthropocene period.

The global temperature increase brings disastrous consequences, endangering the survival of the Earth’s flora and fauna, including human beings. The worst climate change impacts include the melting of the ice mass at the poles, which in turn causes rising sea level, producing flooding and threatening coastal environments through which small island states risk disappearing entirely.
