[Aqualist] Paleovegetation and modelling at EGU2006

[Tim Barrows]

There will be a session about vegetation paleodata and vegetation 
modelling at the General Assembly of the European Geosciences Union 
2-7 April 2006 in Vienna.

http://meetings.copernicus.org/egu2006/index.html

The session is scheduled in the Biogeosciences as BG2.05 (See 
<http://www.cosis.net/members/meetings/programme/view.php?m_id=29&p_id=192>Programme 
http://www.cosis.net/members/meetings/programme/view.php?m_id=29&p_id=192) 
and is called

Integrating Neogene terrestrial vegetation records and models

Session outline

Vegetation and climate show strong feedbacks. Sensibility of the 
vegetation to climate change and, vice versa, influence of the 
vegetation on albedo and the hydrological and carbon cycles are 
important issues with lingering actuality. During the nineties of the 
last century, biome modelling helped to bring very different 
palaeovegetation studies and atmospheric modelling together achieving 
a leap forward in the understanding of the feedbacks between 
vegetation and climate. In the mean time, new proxies have been 
developed; new longer, more detailed, and/or older vegetation records 
have been generated. Climate modelling attempts to give a more and 
more integrated view of the whole Earth system, including vegetation; 
direct modelling of climate and vegetation proxies facilitates 
model-data comparison.
Further progress on past vegetation changes requires intense dialogue 
between modelling and reconstructing people to i) crystallize central 
questions and ii) clarify possible contributions and needs from the 
one or the other side. Our main objective of the session is to 
generate a further opportunity for this dialogue.

Central theme
Climate reconstruction from vegetation proxies and vegetation modelling.

More specific questions

How does variability in time translate into variability in space 
(what data do we need) ?
- For instance, Where do we need proxy studies ? What spatial and 
temporal density do we need ?

Direct modelling of vegetation-related proxies:
- What do we have and what do we need ? What is beyond Plant Functional Types ?
- How to cope with ecological adaptation and other evolutionary processes ?

How many terrestrial vegetation types do we need to distinguish for 
reasonable regional climate reconstructions
(what models do we need) ?

How can terrestrial climate reconstruction and modelling benefit from 
integrated land-ocean time series ?

Deadline for support application is 9 December 2005!

We would be delighted if you would promote the session to others.
Hope to see you in Vienna
