Zmena klímy – možný dopad (nielen) na obyvateľstvo - Prohuman

etween the elements and the climate system, including physical and chemical
changes, still require exploration. At this point, it is worth mentioning that even
the refined results of prognostic (numeric) mesoscale meteorological models are
often incomparably different or entirely incorrect, even though they struggle to
predict weather conditions for just the next few days. For the climate models, the
task is even more complex because of the time and spatial scale. In addition to
that, the unforeseeable political and economic affairs make it even harder to imagine
what the climate will be like in the future. Probably everyone is aware that
any global changes, including for example crises outbursts can radically and effectively
undermine even the most carefully shaped “natural and rational” scenarios.
Moreover, the development of IT allows to make more complex calculations,
with new parameters (climatic factors) and changes in spatial resolution of the
whole atmosphere. The revolution is noticeable if the first and fourth IPCC reports
are compared, and now it is a fact that can be both observed and verified
(fig. 5). Several years ago the so-called hockey stick graph of the global temperature
rise seemed to have no end, as from the eighties it rapidly started a continuous
growth. But the recent few years show that it has been ceased and maybe the
following years will show the opposite tendency.

CONCLUSION
The foregoing considerations, out of necessity, concern only selected climate
change aspects. They are individually discussed in serious, professional reports,
which sometimes treat this topic in a dissimilar way, which only proves that
