It is a great consensus in the scientific community that environmental factors, such as weather conditions and ambient air pollution, have vital impacts on respiratory diseases. Further, these factors imply the potential to have many significant impacts on aeroallergens, and therefore related diseases such as asthma and allergic rhinitis. The impacts are more pronounced in sensitive groups of population, such as children and elderly, living in urbanized areas. Over the last three decades, studies have shown changes in production, dispersion and allergen content of pollen and spores, which may be region- and species-specific. In addition, these changes may have been influenced by air pollutants interacting directly with pollen. It is not easy to evaluate the impact of climate change and air pollution on the prevalence of asthma in general and on the timing of asthma exacerbations. However, the global rise in asthma prevalence and severity suggests that air pollution and climate changes could be contributing. The objective of this review is to summarize the environmental impacts on pulmonary diseases in children based on recent literature over the world. © 2015, Frontiers in Bioscience.

Nastos, P.T. & Kapsomenakis, J. Regional climate model simulations of extreme air temperature in Greece. Abnormal or common records in the future climate?. Atmospheric Research 152, 43 - 60 (2015). WebsiteAbstract
The aim of this study is to analyze and quantify the future projections of heat waves in Greece. For this reason, specific climatic indices were used in the analysis concerning absolute, percentile and duration indices defined by the CCl/CLIVAR/JCOMM Expert Team (ET) on Climate Change Detection and Indices (ETCCDI). The future projections (SRES A1B) of these indices such as summer days, tropical days, maximum daily maximum air temperature, warm days, tropical nights, maximum daily minimum air temperature, warm nights and warm spell duration were carried out using six regional climate models from the ENSEMBLES project, concerning the near future 2031-2050 and the far future 2071-2100 compared to the reference period 1961-1990. The ensemble means along with the inter-model-standard deviations of the examined extreme indices for the future model projections are presented and analyzed. Further, the findings of this analysis are discussed against recent recorded heat waves during 2007, in order to understand if such events are even more extreme or common in the future climate. It is very likely, that the anomalies observed in 2007, especially for extreme indices of minimum air temperature, could be more frequent considered as typical events by the end of the 21th century. © 2014 Elsevier B.V.

The goal of this study is to contribute to the climatology of upper air temperature in the Mediterranean region, during the period 1965-2011. For this purpose, both radiosonde recordings and gridded reanalysis datasets of upper air temperature from National Center for Environmental Prediction-National Center for Atmospheric Research (NCEP-NCAR) were used for seven barometric levels at 850. hPa, 700. hPa, 500. hPa, 300. hPa, 200. hPa, 150. hPa and 100. hPa. Trends and variability of upper air temperature were analyzed on annual and seasonal basis. Further, the impact of atmospheric circulation, by means of correlation between upper air temperature at different barometric levels and specific climatic indices such as Mediterranean Oscillation Index (MOI), North Sea Caspian Pattern Index (NCPI) and North Atlantic Oscillation Index (NAOI), was also quantified. Our findings have given evidence that air temperature is increasing at a higher rate in lower/middle troposphere against upper, and this is very likely due to increasing greenhouse gas concentrations. © 2013 Elsevier B.V.
