«To cause this type of global isotopic shift, you'd have to take all terrestrial plants and burn them into carbon dioxide,» Kessler says, which seems unlikely.

As a result of this annual cycle, together with the continual emissions from fossil fuel burning (particularly over China, Europe, and the southeast United States), carbon levels reach a maximum in the Northern Hemisphere in April, just before terrestrial plants begin to soak up more carbon.

In the above citied letter to Nature the authors concluded out of their experiments: «Here we demonstrate using stable carbon isotopes that methane is readily formed in situ in terrestrial plants under oxic conditions by a hitherto unrecognized process.»

Sitch, S., et al., 2003: Evaluation of ecosystem dynamics, plant geography and terrestrial carbon cycling in the LPJ dynamic global vegetation model.

Ignoring terrestrial carbon led to a nearly complete loss of unmanaged forests by 2100, largely because they were replaced by massive expansions of bioenergy crops that were planted to reduce the use of fossil fuels.

CO2 that goes into the atmosphere does not stay there, but continuously recycled by terrestrial plant life and earth's oceans — the great retirement home for most terrestrial carbon dioxide.

CO2 record are dominated by tropical deforestation variations, and terrestrial carbon cycle changes (respiration in soils, deciduous plants, droughts etc.).

The ocean, with around 38,000 gigatons (Gt) of carbon (1 gigaton = 1 billion tons), contains 16 times as much carbon as the terrestrial biosphere, that is all plant and the underlying soils on our planet, and around 60 times as much as the pre-industrial atmosphere, i.e., at a time before people began to drastically alter the atmospheric CO2 content by the increased burning of coal, oil and gas.

Based on measurements of ecosystem CO2 flux, radiation absorption by plants, crop yields and a model simulating the terrestrial biosphere, a multinational team of researchers has found that during July and August 2003, 500 million tonnes of carbon escaped from the forests and fields across Europe as a result of extreme heat and drought.

And because these floating plants absorb as much of the atmosphere's carbon dioxide - a major greenhouse gas - as do terrestrial plants, they are important to any global climate study.

Terrestrial ecosystems, such as the Arctic tundra and Amazon rainforest, contain a huge amount of carbon in organic matter such as decaying plant material.

It's a terrestrial plant's only source of carbon and at 280 parts per million in the atmosphere a plant must work very hard to extract what it needs out of the gases it does not need.

The ability of terrestrial vegetation to both take up and release carbon and water makes understanding climate change effects on plant function critical.

Terrestrial plants thrive on carbon dioxide, while hydrogen sulfide kills them.

Tropical forests harbour half of all terrestrial plant and animal species and store carbon that would otherwise accelerate climate change.

Carbon stocks: The quantity of carbon stored in biological and physical systems including: trees, products of harvested trees, agricultural crops, plants, wood and paper products and other terrestrial biosphere sinks, soils, oceans, and sedimentary and geological sinks.

«Soil respiration, RS, the flux of microbially and plant - respired carbon dioxide (CO2) from the soil surface to the atmosphere, is the second - largest terrestrial carbon flux.

Eliminate carbon dioxide, and terrestrial plants would die, as would lake and ocean phytoplankton, grasses, kelp and other water plants.
