Quizplus · Accepted Answer

The effects of clouds and the ecosphere on climate are considered the source of the greatest uncertainty in current climate models. This is because clouds are unpredictable and they can have both warming and cooling effects on the climate. Additionally, the impact of human activity on the ecosphere, such as deforestation and agriculture, is complex and difficult to model accurately.
