Question

Explain why the increase in atmospheric carbon during the 2000s does not equal the amount of carbon
released by land use change and fossil fuel emissions.

Answer 1

Answer:

There are many lines of evidence which clearly show that the atmospheric CO2 increase is caused by humans.  The clearest of these is simple accounting - humans are emitting CO2 at a rate twice as fast as the atmospheric increase (naturalsinks are absorbing the other half).  There is no question whatsoever that the CO2 increase is human-caused.  This is settled science.

CO2 increase is natural, not human-caused that atmospheric CO2 increase that we observe is a product of temperature increase, and not the other way around, meaning it is a product of natural variation...it may be the Emily Litellamoment for climate science and CO2 – “Never mind…” (Anthony Watts)

Answer 2

Answer:

The increase in atmospheric carbon during the 2000s does not equal the amount of carbon released by land use change and fossil fuel emissions mostly due to anthropogenic factors.

Explanation:

• Carbon emission has grown many folds over the last decade owing to the fast changing lifestyle of humans.
• The population boom is another factor for increase in carbon emission coupled with deforestation.
• The natural carbon sinks such as the water bodies are also being depleted due to global warming and thus the stored carbon dioxide in them is released to atmosphere.
• Over the years, the carbon footprints are changing; adding to atmospheric carbon.
