IPCC (2007) WG2 Ch. 10.6.2
Glaciers in the Himalaya are receding faster than in any other
part of the world (see Table 10.9) and, if the present rate
continues, the likelihood of them disappearing by the year 2035
and perhaps sooner is very high if the Earth keeps warming at
the current rate. Its total area will likely shrink from the present
500,000 to 100,000 km2 by the year 2035 (WWF, 2005).

Physical Scientists
(Non-communicators)
We might not like the general
media and arts and entertainment
media, but they are our link to the
public.

Experieces with media
Lessons learned
Example 1: Gasherbrum 2 (8035 m)
• Interview and than a drink at the bar
Result:
• erotic dreams at 7.500 m
• faster than R. Messner
• etc.
• don‘t go for a drink!
Have an urgent appointment after the interview,
• fill the interview with (invented) ‚sexy‘ stories
• show great interest in the hard life of a journalist while having a drink
g. kaser * 110122 * cambridge
Example 2:
Avalanche accident in Peru (heavily injured field worker)
• Information oozes to Astria
• Journalist calls
• I refer to a media conference when coming home
• He wants to write a sensetional story, even without information
• never threaten with a media conference (exclusivity)
• have a good lawyer who proves your innocence in the accident
• organise the boot of the J. before publication -
(very) good connections

Rules for the intercourse with journalists
Only written interviews.
Proof reading!
CAUTION!: check also the TITLE and the picture CAPTIONS!
After the interview:
• DON‘T watch TV
• DON‘T listen to the radio
• DON‘T read newspapers
How to avoid annoyances?
g. kaser * 110122 * cambridge
• the subject of study is permanently changing
• measurements cannot be repeated
The dilemma of (climate) reserach (ers)
• This violates the principles of physical reserach
g. kaser * 110122 * cambridge
• to record obeservations
• inventory of the drivers, budget e.g. heat fluxes
• identify the reasons (processes, statistics, modeling)
• seacrh for similar cases in the past (climate history)
• precise rules – providing uncertainties –
awkward terminology
The methods used in (climate) reserach

Wie gehen Journalisten mit mir um?
Example 3:
Error in IPCC WG2 Report: Himalaya glaciers melted by 2035
• Information about my eraly detection of the erreor gets to AFP
• for about 3 weeks journalists call 24h/d from around the world
• „a new climate lie“ = „glacier gate“
•„answer the following 10 questions!“
•„Who is THE culprit “
• patiently (scientifically) explain how the error happened
• „an error can happen in a 3000 pages volume“
• Internationality of the IPCC, (scientific)-cultural differences
• counter question: „does denunciation add to knowledge?“
• Hope that: „Paris Hilton gets pregnant from Roman Polanski!“
Experiences with media
Lessons learned
g. kaser * 110122 * cambridge
Need to be sensational
New (and exclusive) information
→ great theat, fear, names!
account – counter account (a fatal conceptual error!)
→ scientists have different opinions (results)!
The jornalists‘ dilemma
The scientists‘ dilemma
Codes are not unedsrtood outside the community
→ Transformation of information by (i) scientists, (ii) journalists
Consolidation of new knwoledge only after a couple of years
→ no sensation content.
Pressure (appeal) to go (from) public :
→ Reserachers talk as experst and as laymen,
but are always taken as experst (such as I here and today)
g. kaser * 110122 * cambridge
The Earths climate
can develop unpredictable dynamics
when reaching a tipping point and it can tip over
if no swift (within a decade) radical changes
take place in our economic behaviour.
The short time span until 2020
-only two to three legislative periods,
a short economic cycle,
2 olympic summer games ahead –
decides
upon the living conditions of future generations

With this, a perspective of finiteness has come
into the linear progress.
This is unknown, almost monstrous,
to the modern way of thinking.

„The end of the world as we know it“ Harald Welzer u. Claus Leggewie
g. kaser * 110122 * cambridge
Risiks turn back into danger.
Not are only earth‘s resources finite,
with it also
the achievements of western modern age can cease
such as:
market economy, civil society, and democracy.
Climate Change is a Culture Change and an outlook onto future life conditions.
