FOR400Y1 Lecture Notes - Lecture 10: 2Degrees, Non-Renewable Resource, Climate Change Mitigation
Document Summary
For400y - lecture 10: forest carbon and climate change (tony lempriere) Reservoir: component of climate system where ghg sored. Source: process, activity or mechanism that emits a ghg into the atmosphere. Sink: process, activity or mechanism that removes a ghg from the atmosphere. Removal: absorption of ghgs from the atmosphere over a specific area and period of. Climate change mitigation: measures to reduce ghg emissions. Co 2 e = measure of ghg expressed in terms of the amount of co 2 that would have the same effect on climate. Ex: a molecule of methane is equivalent to 28 molecules of co 2 time. Carbon stored in various pools (living biomass, dead biomass, soils) Carbon cycle involves flow of carbon between atmosphere within forest pools. Forest growth through photosynthesis removes co 2 from atmosphere and stores it in the living biomass. Respiration, decomposition, fire emit co 2 to the atmosphere. Harvesting transfers carbon out of the forest for use.
