Every child in school knows that trees absorb carbon dioxide from the atmosphere. Now, this scientific fact has been proven wrong.
Researchers from Western Sydney University, Australia, have concluded that trees do not store as much carbon as it was previously thought. The study, published in ‘Nature Climate Change’, also revealed that Eucalyptus trees may require added nutrients from the soil to grow and will take advantage of carbon dioxide in the atmosphere.
Researchers began to expose large areas of Eucalyptus forests to high levels of carbon dioxide and found that the gas increases the rate of photosynthesis but its level in stems, leaves and wood did not increase.
David Ellsworth, a member of the team who undertook the study, commented:
The world pays a lot of attention to climate change modelling, including predictions on the amount of carbon that will be stored in trees. These reports are based on models and data taken largely from temperate forests where nutrients are in adequate supply, meaning that estimates on carbon absorption do not account for nutrient shortages on forest productivity.
The team also hinted that the global number of carbon storage in forests may be high because many tropical and sub-tropical forests exist on low-nutrient soils. Several greenhouse plants, like tomatoes and cucumbers, are also shot with CO2 to yield bigger, and faster, fruit.
The new research will surely dramatically impact the study of climate change and can provide better solutions for the same.
