11,000 years ago, our ancestors survived abrupt climate change

(CNN)Imagine if, instead of heat this summer, we were faced with a sudden, dramatic cold front that lasted the next 100 years. That is what our hunter-gatherer ancestors lived through 11,000 years ago.

Findings from a Middle Stone Age site named Star Carr in North Yorkshire, England, show that our ancestors resiliently survived the century-long drop in temperature, according to a new study in the journal Nature Ecology & Evolution on Monday.
How they responded to such abrupt climate change could hold key insights for us as we face a different kind of climate change, the researchers said.

Ancient climate change
Paleoclimatologists, who study climates of the past, know that Earth's climate was not as stable for our ancestors as it has been for us.
These abrupt, harsh changes could mean life or death, often forcing whole populations to move if they wanted to survive.
For example, one well-studied event 8,200 years ago was a sudden cold shift that lasted over a century, recorded in Greenland ice cores and within the fossil record across Europe, the researchers said. It occurred when the North American ice sheet decayed after the last ice age and released meltwater into the North Atlantic Ocean, disrupting the currents that brought heat to Western Europe. This triggered large-scale population crashes in northern Britain and large cultural changes in southern Europe, they said.
In studying the Star Carr site, the researchers learned that two events there 9,300 and 11,100 years ago resulted in temperature decreases of 10 and 4 degrees Celsius.

The cold dips have historically been very bad for human kind, while the warm ups have been very good.

I would love to know, specifically, what these "activists " are doing to create a smaller human population. Did they all neuter each other? I really hope so because we don't need these people to populate the Earth.

Junk science is no longer welcome at the Environmental Protection Agency. Administrator Scott Pruitt has declared war on what he calls “secret science” – the process whereby EPA regulators have been able to craft rules using non-publicly-available science data.
Pruitt told Daily Caller:


“We need to make sure their data and methodology are published as part of the record. Otherwise, it’s not transparent. It’s not objectively measured, and that’s important

Funny how you guys always question any arbitrary or subjective law, regulation or statute by asking who then would make the determination who these things would apply to, until it's someone from the nutter side.
