Global warming is primarily caused by the increase in greenhouse gases in the Earth's atmosphere, which trap heat and lead to a rise in global temperatures. Natural causes of global warming include volcanic eruptions and changes in solar radiation. Unnatural causes, on the other hand, are mainly due to human activities such as burning fossil fuels, deforestation, and industrial processes that release large amounts of carbon dioxide and other greenhouse gases into the atmosphere. These human activities have significantly accelerated the rate of global warming in recent decades. **

It ultimately depends on personal preference and the skill of the stylist. **
