There are many hypotheses about overall climate change.Which of the following is correct?

Question

Quizplus · Accepted Answer

The best choice is D because it is widely accepted among scientists that human activity, including the burning of fossil fuels and deforestation, has led to an increase in atmospheric greenhouse gases, such as carbon dioxide and methane. This increase in greenhouse gases is causing the Earth's temperature to rise, leading to overall climate change. Option A is incorrect because the increased atmospheric carbon dioxide does not cause temperatures to cool, but rather it acts as a greenhouse gas and traps heat in Earth's atmosphere leading to higher temperatures. Option B is incorrect because while scientists agree that human activity is a significant contributor to climate change, there are also natural factors such as solar activity and volcanic eruptions that can impact the climate. Option C is incorrect because global warming affects the entire planet and has been shown to have significant impacts on polar regions, including melting ice and rising sea levels.
