Earth Cooling Trend Reversed Around 1900 AD?

The industrial revolutionaries were accidental climate engineers too? A reconstruction of 2,000 years of global temperatures shows that a long-term decline in Earth's temperatures ended abruptly about 1900, replaced by a warming trend that has continued despite the persistence into the 20th century of the factors driving the cooling, according to a new study. The more interesting thing about this report isn't that humans humans are probably causing rising temperatures by causing so much CO2 emissions. That already seems pretty likely. What is more interesting: the long term cooling trend could mean we were headed for another ice age. Maybe only the industrial revolution prevented it. So suppose humans developed more slowly in the industrial revolution was delayed by hundreds...
