In the context of climate change, which one of the following is an example of negative feedback?

Oceans absorbing carbon dioxide from the air pull a warming driver out of the atmosphere, so the process opposes the initial change and behaves as negative feedback.

Warming that raises water vapour adds another heat-trapping gas, amplifying warming instead of opposing it.

Reduced snow cover and melting ice expose darker surfaces that reflect less sunlight, so more heat is absorbed and warming grows.

Global warming raising temperature merely restates the effect and describes no self-correcting loop.

Negative feedback stabilises a system by damping change, whereas positive feedback reinforces and accelerates it.

Ocean uptake and photosynthesis are the main natural sinks that moderate atmospheric carbon dioxide.
