An increase in atmospheric carbon dioxide (CO2) concentration influences climate both directly through its radiative effect (i.e., trapping longwave radiation) and indirectly through its physiological effect (i.e., reducing transpiration of land plants).

Planted in the early 20th century to help control erosion, kudzu is a fast-growing invasive legume that fixes atmospheric nitrogen at a high rate. The Asian native is not just swallowing landscapes and altering ecosystems in the southeastern United States, the plant may also increase ozone pollution. Jonathan Hickman et al.

The daily net ecosystem CO2 exchange, diurnal pattern of net CO2 exchange and ecosystem respiration of Cenchrus ciliaris grassland in semi-arid region were studied during July 2008

Clouds with aerosols conspire to block and reflect away sunlight over the Indian subcontinent, a new research claims. This results in what is called 'solar dimming' lessening the amount of sunlight that reaches Indian soil.
