1 The Carbon Cycle

2 In the most simple terms, the Carbon Cycle is the movement of Carbon through the spheres of the Earth’s systems.

3 In the most simple terms, the Carbon Cycle is the movement of Carbon through the spheres of the Earth’s systems. Step One ~ A plant removes carbon from the atmosphere, to make sugars and biomass (plant parts). This is photosynthesis (6H2O +6CO2 => 6CO2 +C6H12O6)

Step One ~ A plant removes carbon from the atmosphere, to make sugars and biomass (plant parts). This is photosynthesis (6H2O +6CO2 => 6CO2 +C6H12O6) Step Two ~ An animal eats the plant, and excretes it as feces and respiration. 6O2 + C6H12O6 => 6H2O + 6CO2

Respiration is also the equation for the combustion inside a car, or plane, or power plant.

8 Atmosphere can hold massive amounts of CO2
Atmosphere can hold massive amounts of CO2. Large amounts go into it, but hug amounts have then left and gone into the ocean.

9 Atmosphere can hold massive amounts of CO2
Atmosphere can hold massive amounts of CO2. Large amounts go into it, but hug amounts have then left and gone into the ocean. The oceans absorb HUGE amounts of CO2, but the limit is being reached, and the oceans will not be absorbing much more.

10 Atmosphere can hold massive amounts of CO2
Atmosphere can hold massive amounts of CO2. Large amounts go into it, but hug amounts have then left and gone into the ocean. The oceans absorb HUGE amounts of CO2, but the limit is being reached, and the oceans will not be absorbing much more. The geosphere holds most of the carbon, in mountains and rocks. This cycle takes billions of years.

11 Atmosphere can hold massive amounts of CO2
Atmosphere can hold massive amounts of CO2. Large amounts go into it, but hug amounts have then left and gone into the ocean. The oceans absorb HUGE amounts of CO2, but the limit is being reached, and the oceans will not be absorbing much more. The geosphere holds most of the carbon, in mountains and rocks. This cycle takes billions of years. Stores of plant energy (fossil fuels), will release CO2 into the atmosphere as a result of combustion (fast respiration). Because the Hydrosphere and Biosphere cannot absorb any more, and the Geosphere takes billions of years, it will stay in the atmosphere. Rate of climate change will (must) increase.

12 People like to say that climate change is part of a cycle
People like to say that climate change is part of a cycle. They are right.

13 People like to say that climate change is part of a cycle
People like to say that climate change is part of a cycle. They are right, but the cycles take thousands of years, and we are seeing climate changes in 10’s of years.

Carbon does have something to do with it, that much is obvious. CO2 in ppm has never been above 300 parts per million.

20 CO2 is now at 393 ppm. Scripps NOAA data, up from 315 in 1960.

21 The era of procrastination, of half-measures, of soothing and baffling expedients, of delays, is coming to its close. In its place we are entering a period of consequences. Winston Churchill, 1936 speech to Parliament
