Climate change is having a major impact on the agricultural sector, affecting crop phenology and yields. The spring barley is one of the three major crops in Baltic region. The study has analysed the phenological phases of spring barley (Hordeum vulgare), evaluating the onset of three phases, sowing, heading and fully ripe, and the duration between phases over a near century (1928–2019) in Priekuli, Latvia. We have evaluated application of a phenological model for different varieties of spring barley. Air temperat...

Interpretation of climate change and deglaciation events from palaeovarves requires a complete understanding of varve composition, depositional environments and the non-climatic events that may influence varve thickness record. We examined a Baltic Ice Lake varve-thickness chronology from western Estonia, eastern Baltic Sea, composed of 26 individual varve series and spanning 584 years of Late Weichselian deglaciation. The direction (azimuth) to the increasing seasonal layer thickness and correlation between the w...
