Dear colleagues,

Please consider submitting an abstract to the "tipping points" session at
the upcoming Copenhagen science congress on "Climate Change: Global Risks,
Challenges and Decisions", to be held during 10-12 March, 2009. Confirmed
invited keynote speakers include Professor Peter Cox, Professor Kerry Cook
and Professor Andrew Weaver. This meeting forms a crucial lead-in to the
COP15 meeting in Copenhagen in late 2009. Details follow below. Also
note the abstract deadline is 30th September, 2008.

With best wishes,
Matthew England and Tim Lenton


Call for Abstracts: Tipping Elements in the Earth System

Professor Matthew England, University of New South Wales
Professor Tim Lenton, University of East Anglia

The global climate system is highly complex and non-linear, with abrupt
change a common feature of past climate records. While most climate
projections focus on the smooth, predictable aspects of climate change, it
is highly likely that key thresholds for large scale, non-linear change,
or "tipping points", will be encountered over the coming decades.
Critical uncertainties include the amount of forcing required to pass
particular tipping points and the severity of the resulting impacts. In
this session we invite contributions on the nature, proximity and
predictability of tipping points in the Earth's climate system. These may
include: abrupt change in the ocean's thermohaline circulation and sea-ice
cover, irreversible shrinkage of major ice sheets, rapid shifts in
atmospheric systems, and abrupt shifts in some terrestrial and marine

The abstract deadline is nominally Monday 1 September 2008 but please note
that we will accept abstracts for the tipping points session up until 30
September 2008. See for
further details.

"Climate Change: Global Risks, Challenges and Decisions"
10-12 March 2009, Copenhagen, Denmark.

The Danish Government as host of the UN Conference on Climate Change
(COP15) to be held in Copenhagen at the end of 2009 has asked the IARU to
organise this conference as part of the run-up to the COP15. All findings
will be compiled in a book on climate change, and an executive summary
with the main findings from the congress will, after agreement with the
Danish Government, be handed over to policy makers at the COP15 in
Copenhagen at the end of 2009.

The conference organisers are expecting several 1000 delegates to attend
the meeting. Please circulate this announcement to others who may be
interested inparticipating in this session or more broadly in the
Copenhagen Congress.
