Feedback Loops In The Carbon Cycle Positive Flashcards
1
Q
what is positive feedback?
A
when there is already a chain of reactions which amplify any changes to the natural system taking it out of dynamic equilibrium
2
Q
when are wildfires more likely?
A
hotter and drier climates created by global warming
3
Q
what do wildfires release?
A
large quantities of co2 to the atmosphere which have an increased warming effect
4
Q
how is ice reflecting radiation from the sun being amplified?
A
ice is melting
sea levels rising
albedo effect increasing
5
Q
what is higher temperatures doing to permafrost?
A
thawing the permafrost releasing co2 and methane
which has 20 times the warming effect of co2
