Climate change is real and the question is no longer whether the negative effects associated with it will occur but at what rate, with what impact, and if there is anything that can be done about it. Globally, the biggest cause of climate change is the increase in the atmospheric carbon dioxide, which is generated primarily through burning of fossil fuels.
To control this, we need to reduce the amount of carbon generated every year, reduce deforestation, and replace fossil fuels with alternative renewable sources of energy. We need to reduce negative human activities that facilitate the release and increase of greenhouse gases in the atmosphere and eventually cause global warming.
