Processes such as melting ice reducing reflectivity amplify or dampen warming.
Positive: ice-albedo, permafrost carbon release and water vapour. Negative: increased plant growth and cloud formation (complex). Tipping elements may trigger irreversible change.
Feedbacks amplify or dampen forcing. Climate sensitivity is the warming for doubled CO2 (about 3 °C best estimate). Cloud feedback remains uncertain.
Example: the ice-albedo feedback amplifies Arctic warming.

Climate Feedback Loops is one of the 54 topics in Marine & Environmental Biology. It is rated Intermediate, so it suits learners who already know the core vocabulary. Related topics in this area include Permafrost and Methane, Deforestation, Soil Ecology.
As snow melts, darker ground absorbs more sunlight.
Work through the Beginner topics in Marine & Environmental Biology first, such as Oceans, Ocean Zones, Plankton, then return to Climate Feedback Loops. Intermediate topics assume the Beginner vocabulary.
The closest topics to Climate Feedback Loops are Permafrost and Methane, Deforestation, Soil Ecology, Thermohaline Circulation. Comparing them side by side is a good way to see how the ideas connect.
Read the summary and the in-depth section, then use the quick check on the interactive lesson for Climate Feedback Loops. To practise the whole of Marine & Environmental Biology, use the Marine & Environmental Biology quiz.
Climate Feedback Loops: Processes such as melting ice reducing reflectivity amplify or dampen warming. Permafrost and Methane: Thawing frozen soils release methane and carbon dioxide, accelerating warming. Read both side by side and note what each one explains.
First, read the summary and write the definition in your own words. Second, read the in-depth section and note any example. Third, compare it with Permafrost and Methane and explain the difference aloud. Finally, take the Marine & Environmental Biology quiz and come back to this page for any question you miss.
