Question

Quizplus · Accepted Answer

The increase in global temperature has been observed and proven through numerous scientific studies. It has been attributed to the increasing levels of carbon dioxide and other greenhouse gases in the atmosphere, mainly from human activities like burning fossil fuels. This global warming has serious consequences such as sea level rise, extreme weather events, and disruption of ecosystems. The depletion of the ozone layer, on the other hand, is caused by other pollutants and chemicals, like chlorofluorocarbons (CFCs), and has different effects such as increased risk of skin cancer and damage to crops. Option A is incorrect as global warming is an observed phenomenon. Option C is incorrect as global warming and ozone depletion are two different environmental issues. Option D is also incorrect as global warming has significant consequences.
