The IPCC (International Panel on Climate
Change) had to wait 17 years before seeing
its objectives translated into quantified targets,
the famous 2°C temperature increase threshold.
Although the IPCC Vice-Chair, the climatologist
Jean-Pascal van Ypersele, believes it is a figure
that should be regarded with caution, the
progress it has represented should not be
under-estimated. Today, governments the world
over are being urged to act quickly to review
targets that are deemed insufficient.
Our dependence on oil – this fossil fuel that
we must abandon, and not only because
Copenhagen,
a missed chance?
its reserves are depleted – is slowly beginning
to end. There is increasing research on other
energy sources. Also, after the false start
of the first generation agrofuels that proved
so costly, biofuels remain full of promise.
But the situation is urgent, that much
we do know. Evidence of the impact of global
warming on ecosystems is growing all the time.
Until recently we were not sure, for example,
that carbon dioxide would change sea water
composition to the point of threatening marine
ecosystems and biodiversity. We now know
this to be the case and ocean acidification
has been added to the list of worrying
environmental problems.
The figures are growing more accurate and
the climate models more refined as the projections
acquire more precise degrees of probability but
grow ever more sombre in the process. Science
is advancing, albeit without absolute certainty
and thus amid debate. So much the better.
Witness these scientists whom we have grouped
together as ‘climate sceptics’ and who continue
to doubt the anthropic origin of global warming
and/or the sound basis of the measures
proposed to combat it.
Recent years have brought demands for greater
political commitment and a total review of
our consumption practices, but without really
achieving the hoped for effects. The agreements
reached at the Copenhagen Climate Summit
last December are the most recent example.
But these injunctions are causing us to leave
our fool’s paradise in which we knew nothing
and wasted everything. We must now reach
the other shore.
