Effects of combined increase in temperature and CO2 concentration on the weathering activity of phototrophic organisms inhabiting granitic rocks and its implications in terms of cultural heritage conservation

The increase in CO2 concentration and temperature observed in the current context of climate change may cause changes in the behavior of phototrophic organisms colonising stone cultural heritage, leading to undesirable changes in terms of biodeterioration. In this study, we examined the combined eff...
