We tend to think of the increasing levels of CO2 as a bad thing. But these increasing levels have also some interesting side effects that surprise even scientists.

A new study conducted by CSIRO has been found to increase CO2 levels in the world's arid regions over the past 30 years.

In Findings based on satellite observations, the Commonwealth Scientific and Industrial Research Organization - which is Australia's national science agency and one of the largest and most diverse research agencies in the world - has collaborated with the Australian National University (ANU), and found that this 1982-2010 across parts of the arid areas studied in Australia, North America, the Middle East and Africa. Apparently, the deserts are getting greener.

CO2 fertilization occurs when higher levels of carbon dioxide enable plants in their leaves during photosynthesis. Plants respond by creating more leaves and increasing overall cover in arid areas.

    "On the face of it, elevated CO2 boosting the foliage in dry countries is good news and could assist forestry and agriculture in such areas; CSIRO researcher Dr Randall Donohue says: "There is a great deal of potential," he says.

CO2 levels can generate positive effects on deserts and desert agriculture. The on the other hand, this increase in foliage is more flammable, drier and caused by phenomena that threatens the existence of humanity.

However it might prove one important thing - the solution for climate change
