Question
Draw a feedback loop describing the effect of climate change on permafrost
Solution
Sure, here's a step-by-step description of a feedback loop describing the effect of climate change on permafrost:
-
Start with the initial condition: The Earth's atmosphere is warming due to increased greenhouse gas emissions (GHGs), a phenomenon known as climate change.
-
Draw an arrow from this box to a new box: This warming causes permafrost (permanently frozen ground in the Arctic regions) to thaw.
-
From the "thawing permafrost" box, draw an arrow to a new box: As permafrost thaws, it releases stored carbon in the form of carbon dioxide (CO2) and methane (CH4), both potent greenhouse gases.
-
Draw an arrow from this box back to the initial "climate change" box: The release of these gases into the atmosphere further exacerbates climate change, leading to more warming.
-
Finally, draw an arrow from the "increased warming" box back to the "thawing permafrost" box. This completes the feedback loop, as increased warming will lead to more permafrost thaw, which will release more greenhouse gases, leading to more warming, and so on.
This is a positive feedback loop because the effect of the process is to increase the initial stimulus (in this case, climate change), rather than to dampen it.

Which of the following correctly explains a positive climate feedback loop found in the Arctic?A.Increased melting of permafrost increases Earth’s ability to absorb methane gas, which decreases greenhouse warming and decreases the melting of permafrost.B.Increased global temperatures lead to decreased sea ice coverage and decreased albedo, which further increases global temperatures.C.Increased evaporation and cloud formation decreases the amount of solar energy reaching the surface of Earth, which leads to cooler temperatures at the surface and decreased evaporation and cloud formation.D.Increased precipitation increases the size of high albedo snowpack in polar regions, which leads to increased habitat for Arctic organisms such as polar bears.
