Just finalizing: recent world temperature growth as well as countable climate changes are not the subject of purely human impact on environment, but a result of a decent number of continuous processes, including solar, planetary and volcanic activities — as well as it was stated long before about the origins of the ice ages, that brought real changes to Earth's climate. Second — no exact mathematical model of recent climate change was brought to public in order to be viewed and discussed widely enough to ensure it is not all just biased ad hoc informational warfare product. And, finally, third — climate change, being openly used as the main leftish political agenda nowadays, makes me think, that it is a part of a deliberate act around struggling for power in the U.S. and has nothing to do with physical reality at all.
