Positive and Negative Climate Feedback Loops

Climate Feedback Loops

Climate feedback loops either amplify or reduce climate change. For example, a warmer climate could increase cloudiness because of the increased water vapor in the atmosphere.

Because clouds reflect 1/3 of incoming solar radiation, more clouds could slow the increased warming from less heat absorption. This is an example of a negative feedback loop.

An example of a positive feedback loop is the melting of permafrost. This amplifies climate change because its methane contents would be released into the atmosphere.
