Deserts may have a big hand in lessening impact of global warming in the atmosphere, said researchers from University of Washington. The research team believes that 'dry areas filled with scrubby vegetation and sand' are absorbing excess of carbon dioxide from the atmosphere.

Global warming is caused by increase in levels of carbon dioxide, carbon monoxide and other harmful gases in atmosphere. In a 10-year study, researchers measured levels of carbon dioxide absorbed by soil and plants in the California Mojave Desert.

They found that increased carbon dioxide in atmosphere resulted in formation of rhizosphere, a microbe-rich area around plant roots, which further helps in absorbing carbon dioxide. Their findings illustrate that desert ecosystems may increase carbon intake in future to account for 15% to 28% of carbon currently being absorbed by land surfaces.
