TL;DRAbstract
The Enhanced Greenhouse Effect (EGE) refers to the radiative forcing of the Earth's climate through the anthropogenic loading of the atmosphere with radiatively active gases. Climate modelling studies indicate that an equilibrium doubling of CO2 is likely to cause global mean surface temperatures to increase by 1.4to5.8 °C (Houghton et al., 1990; IPCC 2001). There will be changes in precipitation patterns as well as changes in the frequency and intensity of extreme rainfall events (Houghton et al. 1990). A changing climate will have consequences for agricultural systems, many of which already experience high year-to- year yield fluctuations due to variable weather. Because many weed populations show great genetic variation, it is possible that with a changed climate, weeds will achieve greater competitive fitness against the crop plants with which they compete. Climate change impacts-assessment studies were carried out on wild oat (Avena fatua L.), a persistent annual weed of the world
