Definition of carbon source
Process that releases to atmosphere
Human activities adding
Human activities adding
Fossil fuel combustion, limestone roasting
Natural carbon sources
Natural carbon sources
Respiration, forest fires, volcanic eruptions
Definition of carbon sink
Definition of carbon sink
System absorbing more carbon than it releases
Examples of carbon sinks
Examples of carbon sinks
Photosynthesis, ocean absorption, rainfall
Why forests are carbon sinks
Why forests are carbon sinks
Trees absorb , store carbon in wood & roots
Peatlands/wetlands as carbon sinks
Peatlands/wetlands as carbon sinks
Waterlogged conditions trap carbon, prevent decomposition
Natural carbon cycle balance
Natural carbon cycle balance
Processes adding roughly equal those removing it
Human impact on carbon cycle
Human impact on carbon cycle
Adding faster than natural sinks can remove it
Effect of extra in atmosphere
Effect of extra in atmosphere
Traps more heat, contributes to global warming
Impact of damaged carbon sinks
Impact of damaged carbon sinks
Reduced ability to absorb , accelerates climate change
