Call for Papers: Phenology session at European Geosciences Union General

We cordially invite you to submit a contribution to the following session:

"Shifting Seasons: Phenological evidence from observations, 
reconstructions, measurements and models (co-sponsored by PAGES & ILEAPS)"

The IPCC AR4 report from 2007 presented unequivocal evidence of regional 
to global-scale change in seasonality, as evidenced by plant and animal 
phenological records. Observations from all continents and several oceans 
now show that many physical and biological natural systems are being 
affected by regional climate change, particularly increases in 
temperature. To allow a consistent global analysis, AR4 focused only on 
significant trends from traditional phenological observations during the 
20-year period between 1970 and 1990. However, there has been much 
additional research in recent years that lends new insights into spatial 
and temporal patterns of interrelationships between climate change and
organisms, with attendant impacts on carbon dynamics, species 
interactions, biogeochemistry, etc. This new research has focused on novel
investigations of data, and the development and application of new methods 
and techniques for investigation of phenology. However, robust 
identification of long-term centennial phenological trends and of
systematic decadal fluctuations in biotic and abiotic variables
requires compilation and analysis of much longer time series from 
historical evidence. Integration of historical and contemporary data, on 
global scales, will be required to reliably understand the processes
underlying phenological dynamics. This session would also serve as an
opportunity to discuss and strategize on the development of a global 
network of detailed regional and seasonal observations of phenology.

Therefore, we invite contributions with cross-disciplinary perspectives 
that present seasonality changes based on recent plant and animal 
phenological observations, historical documentary sources, or seasonality 
measurements using climate data, remote sensing, flux measurements or 
modelling studies. We seek contributions across spatial and temporal
scales that compare and integrate seasonality changes across methods
and that advance our understanding of seasonality response to long-term 
climate change and single extreme events.
