Global Carbon Cycle
Carbon moves through the atmosphere, biosphere, geosphere, and hydrosphere.Gas hydrates (orange) are shown in marine sediments, but are also buried beneath permafrost sediment in Arctic regions. Although gas hydrates are...

The Carbon Cycle
Carbon stocks in forest areas comprise carbon in living and dead organic matter both above and below ground including trees, the understorey, dead wood, litter and soil. On a global scale, vegetation and soils are e...

The carbon cycle
The global carbon cycle shows the carbon reservoirs in GtC (gigatonne= one thousand million tonnes) and fluxes in GtC/year. The indicated figures are annual averages over the period 1980 to 1989. The component cycles ar...

Projected changes in CO2 and climate: assumptions in the IPCC 1992 scenarios
Projected anthropogenic CO2 emissions from fossil fuel use, deforestation and cement production are shown for some of the IPCC emission scenarios. The highest emission scenario - IS92e - assumes moderate population grow...

Carbon cycle
Carbon is the basis of all organic substances, from fossil fuels to human cells. On Earth, carbon is continually on the move – cycling through living things, the land, ocean, atmosphere. What happens when humans start dr...

Ocean carbon cycle
Without the contribution of oceans and coastal ecosystems to global biological carbon sequestration today’s CO2 concentration in the atmosphere would be much larger than it is. But the uptake capacity of oceans and coa...

Carbon cycle
Living systems play a vital role in the carbon cycle. Photosynthesising organisms – mostly plants on land and various kinds of algae and bacteria in the sea – use either atmospheric carbon dioxide or that dissolved in se...

The Carbon cycle
The figures indicate carbon storage and flows, expressed in Gigatonnes (1 000 million tonnes) of carbon. The arrows are proportionate to the volume of carbon. The figures for the flows express amounts exchanged annual...

Carbon Cycle
Blue and green carbon process.Oceans are crucial in the global carbon cycle. It was here where life first evolved; they are the source of our wealth and development. The living oceans capture over half of all the Green c...
