The climate changes on Earth tend to be self-amplified. For example, the Earth is currently going through a
warming trend. As the Earth's temperature rises, the ice caps and sea ice melt, reflecting less solar radiation. This
results in more absorption of the Sun's heat, causing the Earth's temperature to rise more, and the ice to melt
more. This is an example of what type of system?
• a no feedback system
O a negative feedback system
•
neutral feedback system
O a positive feedback system
