Quizplus · Accepted Answer

Global average air temperatures have been increasing since the Industrial Revolution, and scientific evidence suggests that human activities, such as the burning of fossil fuels and deforestation, are causing an increase in the greenhouse effect, leading to further warming of the planet.
