Climate feedback loops are processes that either amplify or diminish the effects of climate factors. Essentially, they make the impacts of key climate factors stronger or weaker, starting a chain reaction that repeats again and again. What is a Feedback Loop? There are negative and positive climate feedback loops.What happens if there is no negative feedback in the climate?
Negative feedback loops are vital in the global climate system. Without the regulating action of the negative feedback loop, a positive loop can spiral out of control, creating irreversible changes in the climate system. This is called a “tipping point.”What is the positive feedback loop in the Arctic?
Another positive feedback loop in the Arctic with global implications: the reduction in sea ice coverage, particularly in the summertime. Arctic Ocean ice cover is integral to regulating global land and sea temperatures. Sea ice creates a large white surface that reflects solar radiation away from Earth.What is the difference between positive and negative feedback loops?
POSITIVE FEEDBACK LOOP: In a positive feedback loop, an initial warming triggers a feedback to amplify the effects warming. NEGATIVE FEEDBACK LOOP: Whereas negative feedback loops reduce the effects of climate change.
