 ''How Mathematics helps structuring climate discussions''

.

Abstract:

Mathematics in climate research is often thought to be mainly a provider of

techniques for solving the continuum mechanical equations for the flows of

the atmosphere and oceans, for the motion and evolution of Earth’s ice masses,

and the like. Three examples will elucidate that there is a much wider range

of opportunities.              

 

Climate modellers often employ reduced forms of “the continuum mechanical

equations” to efficiently address their research questions of interest. The

first example discusses how mathematical analysis can provide systematic

guidelines for the regime of applicability of such reduced model equations.

 

Meteorologists define “climate”, in a narrow sense, as “the statistical

description in terms of the mean and variability of relevant quantities over

a period of time” (World Meteorological Society, http://www.wmo.int; see the

website for a broader sense definition). Now, climate researchers are most

interested in changes of the climate over time, and yet there is no unique,

well-defined notion of “time dependent statistics”. In fact, there are

restrictive conditions which data from time series need to satisfy for

classical statistical methods to be applicable. The second example describes

recent developments of analysis techniques for time series with non-trivial

temporal trends.

 

Modern climate research has joined forces with economy and the social sciences

to generate a scientific basis for informed political decisions in the face

of global climate change. One major type of problems hampering progress of

the related interdisciplinary research consists of often subtle language

notion of “vulnerability” has helped structuring related interdisciplinary

research efforts.
