The recurring theme of civilization’s relationship with climate is that the end of each warming period went badly for humanity.
Man’s fossil fuels had little to do with the enduring climate change Al Gore would prefer you not know about.
In 2009, there was a massive email leak from the Climatic Research Unit (CRU) at the University of East Anglia. Supporters of global warming claimed the disclosures were out of context while opponents claimed they showed efforts to manipulate data. One of the quoted emails, Professor Phil Jones, while discussing paleo-data used to reconstruct past temperatures, says, “I’ve just completed Mike’s Nature trick of adding in the real temps to each series for the last 20 years (ie from 1981 onwards) and from 1961 for Keith’s to hide the decline.” (Emphasis added.) The House of Commons investigated and concluded, “insofar as we have been able to consider accusations of dishonesty—for example, Professor Jones’s alleged attempt to ‘hide the decline’—we consider that there is no case to answer.”
Every time a north wind blows hot air over Adelaide, some Chicken Little cries “Global Warming”. And when an El Nino predictably causes a hot year like 1998 or 2015/16, some sensation-seeker croaks “hottest year eevah”.
