Water Cycle.

• Positive Feedback:

  higher global temps increase the melting of snow and ice ➡️ reduction of surface albedo ➡️ more sunlight absorbed by land and sea ➡️ temps increase ➡️ more melting in cryosphere.
• Negative Feedback:

  increase in farming production increases amount of CO2 in atmosphere, increasing temps ➡️ greater evaporation rates ➡️ more water vapour in the atmosphere ➡️ more clouds form ➡️ increasing cloud cover reflect more of suns energy back into space ➡️ temps fall.
