pretty sure this can be disproved just be the changes taken place while 'men' have keep records.... in the last 1000 years there have been drastic changes.. people didn't cause any of this
'During a period from about 750 BC to 200 BC, before the founding of Rome, temperatures dropped and European glaciers advanced. Then the climate warmed again, and by 150 BC grapes and olives were first recorded to be cultivated in northern Italy. As recently as 1,000 years ago (during the “Medieval Warm Period”), Icelandic Vikings were raising cattle, sheep and goats in grasslands on Greenland’s southwestern coast. Then, around 1200, temperatures began to drop, and Norse settlements were abandoned by about 1350. Atlantic pack ice began to grow around 1250, and shortened growing seasons and unreliable weather patterns, including torrential rains in Northern Europe led to the “Great Famine” of 1315-1317.'
-ended the crusades, precipitated the 100 years war
'Temperatures dropped dramatically in the middle of the 16th century, and although there were notable year year-to-year fluctuations, the coldest regime since the last Ice Age (a period termed the “Little Ice Age”) dominated the next hundred and fifty years or more. Food shortages killed millions in Europe between 1690 and 1700, followed by more famines in 1725 and 1816.
-brought on the French Revolution - the famous phrase 'let them eat cake' refers to a shortage of flour, except for the higher grade 'cake flour'
The end of this time witnessed brutal winter temperatures suffered by Washington’s troops at Valley Forge in 1777, and Napoleon’s bitterly cold retreat from Russia in 1812.'
'Although temperatures have been generally mild over the past 500 years, we should remember that significant fluctuations are normal. The past century has witnessed two distinct periods of warming. The first occurred between 1900 and 1945, and the second, following a slight cool-down began quite abruptly in 1975. That second period rose at quite a constant rate until 1998, and then stopped and began falling again after reaching a high of 1.16 degrees above the average global mean.
About half of all estimated warming since 1900 occurred before the mid-1940s despite continuously rising CO2 levels. Even U.K. East Anglia University Climate Research Unit (CRU) Director Phil Jones has admitted that there has been no statistically significant warming for at least a decade. He has also admitted that temperatures during the Middle Ages may have been higher than today.
So perhaps you’ll wish to ponder this question; Given that over most of the Earth’s known climate history, the atmospheric CO2 levels have been between four and eighteen times higher than now – throughout many times when life not only survived but also flourished; times that preceded humans; times when CO2 levels and temperatures moved in different directions – how much difference will putting caps on emissions accomplish? Consider also that about 97% of all current atmospheric CO2 derives from natural sources.
--- so very many human events are tied to the climat changes if you would only look
