Climate Science
Introductory Remarks
Climate
is
the
weather
averaged
over
several
decades.
While
it
is
relatively
easy
to
observe
daily
variations
of
the
temperature,
humidity
or
wind
speed,
changes
of
the
climate
requires
to
measure
smallest
trends
of
these
strongly
varying
quantities
over
many
years
and
large
areas.
Even
more
difficult
is
to
make
reliable
climate
prognoses,
when
the
origin
and
interaction
of
some climate drivers are not known or not fully understood.
Over
recent
years
climate
science
has
rapidly
developed
to
an
interdisciplinary
branch
of
sci
-
ence
and
now
adays
covers
many
of
the
classical
disciplines
like
meteorology,
geology,
earth-
and
atmosphe
ric
physics,
chemistry
and
biology,
pale
ontology
or
astrophysics.
Meanwhile
it
even
includes
subjects
like
climate-ecology,
-health,
-psychology,
-law
and,
of
course,
climate
politics.
And
indeed
for
understanding
such
an
extremely
complex
‘phenomenon‘
like
climate,
interdisci
plinarity is an absolute requirement.
But up to now climate science suffers from some principal problems:
1.
Despite considerably improved measuring techniques for temperature, humidity, clouds or
sea-level heights - meanwhile covering the whole planet by means of satellite techniques -
direct measurements are only available for relatively short observation periods. For longer
trends researchers have to rely on proxy data like ice cores, stalactites, dendrology or sto-
mata of leaves with much higher uncertainties.
2.
Up to now the main processes and drivers for a changing climate are not really understood.
There exist different hypotheses but because of the long time constants and a lot of compe-
ting effects, it is extremely difficult to verify one of them. Only climate models based on
many assumptions and endless parameters can be used to simulate the past and future
climate.
3.
The different research fields are not really integrated and do not form a common discipline.
Often scientists proceed in their original research but under the label of climate science,
which is known to be well funded. Meanwhile climate covers all fields of our society, and any
inconvenient developments are traced back to climate. Already brief insinuations of danger
or catastrophes assumed to result from climate changes give the highest guarantee for
receiving attention from media, politics and finally for further funding.
4.
As long as science cannot explain unambiguously the processes responsible for previous
and future climate variations, speculation and ideology defeat serious science. It is easier
and more spectacular to retrace all changes to human activities and to neglect any natural
effects.
5.
At present a lot of fundamental research of serious scientists is no longer recognized.
Instead, ideologized environmental and political organizations, which don‘t care about real
science, dictate our actual environmental and energy politics. Our society and particularly
some of our politicians are manipulated and indoctrinated by these groups, which believe:
“The only way to save our planet is to stop all anthropogenic CO
2
-emissions.“
