What is earth's energy balance?Show answer
Climate reflects the balance between energy arriving from the Sun and energy radiated back to space. Anything that changes incoming solar energy, how much is reflected, or how much heat is trapped by the atmosphere acts as a climate forcing. Natural forcings have driven ice ages and warm periods long before humans.
What is feedbacks amplify change?Show answer
Feedbacks can magnify a small forcing.
What are proxy evidence for past climates?Show answer
Because instruments only record the last century or two, scientists reconstruct earlier climates from proxies.
