Mean air temperature rise by 3°C since 1947(data G. Milinevski and colleagues, Ukraine)
clicOPEN IPY34 – interdisciplinary concept
Driver: air warming

1: forcing factors driven by aerial warming- glacier mass balance- newly ice free areas- sediment and fresh water transport
2: ecosystem response - environmental conditions- terrestrial and marine community structure and dynamics
3: species / population response- adjustment to changing conditions (abiotic, biotic)- physiological stress signals

effects
clicOPEN IPY 34 – science plan
• Genetic diversity • Biodiversity• Trophic structure & flow • Interaction strength
• Age/size of bivalve populations• energy reserves • Critical limits (T,S, Sed Cov, O2)• Lifetime models of fitness params• Molecular stress tags
• Use local data to feed spatial glacier melt models •. Long term data to model past glacier melt • local sediment discharge Water column• snow dynamics on ice free areas• coastal sediment cores and seismic data
Terrestrial re-colonization of ice free areas
