9. Links between Carbon and water cycle
evidence of increasing carbon in the atmosphere
In 1750, Industrial Revolution, CO2 levels were at 280ppm.
2018 it was 410ppm
deforestation limits photosynthesis.
Population growth and development
needs more oil to balance production/consumer rate.Decomposition of organic waste in landfill sites.
Hockey stick graph
shows gradual growth of CO2 up to early 1900s and then very steep growth.
Global temp have increased by 0.8 degrees
rising CO2 emissions and energy budget
global heat budget -
state of balance between incoming soil radiation received by the earth's atmosphere and earth's reradiated heat
causes on increasing carbon stores
link to energy budget balance and graphical evidence of carbon in atmosphere from Hockey Stick Graph
2/3 fossil fuel burning
1/3 deforestation and agricultural
toxic gases at the highest levels for over 650,000 years
