Increased carbon dioxide concentration, rise in temperature and drought stress are important key factors causing frequent occurrence of climate events. Important adaptation strategy such as modification of phenological pattern to avoid stressful period during plant development will be key feature in crop plants. In addition, comprehensive understanding of plants response to elevated CO2 concentration, temperature and drought stress alone or in combination will be needed to acclimatize crop plant to these changes. Study of climate variability impact on wheat production concerning mitigation strategies is need of time in order to reduce the risk of climate change on crop yield and growth. Similarly, information about the time in which climate variable(s) occurred in the field is important as the severity of its effect/their combined effect can vary largely. Agronomic practices such as cultivar choice, water and nitrogen supply, nutrients availability and growing conditions should be taken into account to design adaptation options. The failure of agriculture to adapt to climatic variability will impact global food, especially wheat production. A holistic approach will be paramount to sustaining agriculture and the vitality of the world in the face of climate change

Over the last two centuries the atmospheric CO2 level has exhibited a consistent rise, leading to an increase in the greenhouse effect. This level is now 35% higher than it was before the industrial revolution. On the basis of various scenarios from the Special Report on Emissions it is expected to rise from the present level of 385 ppm to 650–970 ppm by the end of the 21st century.Plant biomass and resistance of winter wheat to various powdery mildew pathotypes were investigated at normal (400 ppm) and enhanced (700 ppm) atmospheric CO2 levels in a greenhouse. Wheat cultivars Ukrainka and Mv Hombár, and 12 lines from the mapping population developed from their cross and exhibiting different level of resistance were tested.The results showed that the atmospheric CO2 level had little influence on the resistance of winter wheat to powdery mildew infections based on the percentage of leaf area covered whole plant percentage severity. In response to higher atmospheric CO2 level there was an increase in the aboveground biomass of the winter wheat genotypes tested in the present work, leading to an increase in plant height and in stem and leaf weight. However, the number of tillers and the grain yield did not increase compared with the values recorded at normal atmospheric CO2 level.

Both the total amount of precipitation falling on Earth's surface and the fraction of the surface area on which it falls represent two key global climate indicators for Earth's global hydrological cycle. We show that the fraction of Earth's surface area receiving daily precipitation is closely connected to the global statistics of local wet-day frequency as well as mean precipitation intensity. Our analysis was based on the ERA5 reanalysis which also revealed a close link between the global mean of the mean precipitation intensity for each grid box and the total daily precipitation falling on Earth's surface divided by the global surface area fraction on which it falls. The wet-day frequency and the mean precipitation intensity are two important statistical indicators for inferring effects of climate change on society and nature as they represent key parameters that can be used to approximately infer the probability of heavy rainfall on local scales. We also found a close match between the global mean temperature and both the total planetary amount of precipitation and surface area in the ERA5 data, hinting at a dependency between the greenhouse effect and the global hydrological cycle. Hence, the total planetary precipitation and the daily precipitation area represent links between the global warming and extreme precipitation amounts that traditionally have not been included in sets of essential climate indicators.
