This Concept Map, created with IHMC CmapTools, has information related to: Guzman_CarbonCycle, We know the rise in CO2 is due to humans because: ???? We can measure the "age" of carbon in the atmosphere., The Carbon Cycle is The sum of the processes through which carbon is cycled through various reservoirs., A continuous rise in atmospheric CO2 over the past 200 years. this means There is increased CO2 uptake by the oceans and land., The Carbon Cycle is Altered via anthropogenic addition of more CO2 to the atmosphere., Altered via anthropogenic addition of more CO2 to the atmosphere. via deforestation, A system of recycling. ???? The cycle of uptake and relase of carbon molecules (particularly in the form of CO2) is balanced., A continuous rise in atmospheric CO2 over the past 200 years. this means More "heat-trapping gases" are absorbing and re-radiating heat to the earth's surface., More "heat-trapping gases" are absorbing and re-radiating heat to the earth's surface. so Earth's surface temperature gets warmer (because of planetary energy balance)., Oceans (dissolved CO2, calcium carbonate shells,etc.) both Biosphere (All living and dead organisms not yet converted to organic matter)., Soil (organic matter) contains 1,600 GtC, We can measure the "age" of carbon in the atmosphere. by Measuring the ratio of radioactive 14C to non-radioactive 12C in the atmosphere., The Carbon Cycle is A system of recycling., Major reservoirs of carbon: ???? Lithosphere (fossil fuels and sedimentary rock), Major reservoirs of carbon: ???? Carbon is not removed in this system, it is recycled through many different reservoirs., These processes include: ???? Photosynthesis, Major reservoirs of carbon: ???? Biosphere (All living and dead organisms not yet converted to organic matter)., The sum of the processes through which carbon is cycled through various reservoirs. ???? These processes include:, Carbon is not removed in this system, it is recycled through many different reservoirs. ???? Only processes acting over hundreds or thousands of years rovide a net emoval mechanism for carbon., This addition has led to a rapid increase in atmospheric CO2 not matched by natural removal mecahnism. resulting in A continuous rise in atmospheric CO2 over the past 200 years., Major reservoirs of carbon: ????
