negative feedback loop - carbon cycle Flashcards
what does increased photosynthesis by plants and rising global temperatures allow?
vegetation to grow in new areas
example of vegetation has grow in new area?
where permafrost has melted
what does new vegetation absorb?
CO2 from the atmosphere, decreasing the warming effect
what can higher temperatures and more co2 cause for plants?
greater carbon fertilisation
what is carbon fertilisation?
plants absorbs more co2, reducing the levels of co2 and the rates of warming and then the carbon fertilisation, if temperatures decline - repeating
photosynthesis phytoplankton energy is boosted by
warmer oceans and more sunlight due to climate change
what does a chemical by the plankton cause?
cloud formation
what does an increase cloud cover decreases?
warming by the sun
what does more photosynthesis reduce?
co2 level - reducing warming levels
