Conscious Choice cover

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of founder of the Mars Society.

Antarctic ice sheet thicker than expected

The uncertainty of science: New measurements of the Antarctic ice sheets using an unmanned underwater drone have found them to be much thicker than expected.

Risky robotic exploration of the vast expanse of sea ice around Antarctica has revealed it to be far thicker in many places than previously measured. “The conventional picture of Antarctic sea ice being a thin veneer over the ocean is probably only true for some portion of it,” says Ted Maksym, an ice researcher at Woods Hole Oceanographic Institution in Massachusetts (WHOI). “We need to do a better job of surveying the overall ice cover.”

Previous observations of the thickness of Antarctic sea ice produced a mean draught — the depth between the waterline and the bottom of the ice sheet — of around 1 metre; the new work gives a mean draught of over 3 metres. And a previous maximum recorded ice-sheet thickness of 10 metres has now been increased to 16 metres.

Near the end of the article there is also this:

The more data scientists can gather about Antarctic sea ice, the more they can unpick why climate models struggle to accurately predict its extent. Although researchers have been generally successful at modelling the huge declines in Arctic sea ice, the extent of Antarctic sea ice has actually increased in recent years, contrary to the predictions of models.

Actually, the Antarctic sea ice has grown to record size in recent years, and the Arctic sea ice has significantly recovered in the past two years, all contrary to all climate models.

“But the science is settled,” whines a certain unnamed politician. “This can’t be true! Zimmerman must be a racist for writing it!”
