The Sound Of Settled Science

Popular Mechanics;

A new study led by geologists at the University of Johannesburg found that compounds in the Hypatia stone are distinct from anything discovered in the solar system. The researchers therefore conclude that parts of the rock formed before the solar system, and if these compounds are not presolar, the prevailing idea that the solar system formed from a nebula of homogenous gas is called into question.

The discovery of two infants, ceremonially buried by a previously unknown population of ancient humans in Alaska around 11,500 years ago, offers stunning new clarity to the story of how humans came to inhabit the Americas, according to a new scientific paper.
By confirming the theory that Indigenous Americans are descended from Asians, the find also threatens to inflame a cultural controversy that has long troubled the study of human origins in the New World.

Cloud cover and the creation there of.

Last week WUWT laid out some breadcrumbs. Yesterday, we got back home.

The implications of the study suggests that the mechanism can have affected:
The climate changes observed during the 20th century
The coolings and warmings of around 2°C that have occurred repeatedly over the past 10,000 years, as the Sun’s activity and the cosmic ray influx have varied.
The much larger variations of up to 10°C occurring as the Sun and Earth travel through the Galaxy visiting regions with varying numbers of exploding stars.

This should be fun.

What Would We Do Without Experts?

By its fruit the tree is known, and the tree of expertise hasn’t been doing well lately. As Nassim Taleb recently observed: “With psychology papers replicating less than 40%, dietary advice reversing after 30 years of fatphobia, macroeconomic analysis working worse than astrology, the appointment of Bernanke who was less than clueless of the risks, and pharmaceutical trials replicating at best only 1/3 of the time, people are perfectly entitled to rely on their own ancestral instinct and listen to their grandmothers.”

We’ve noticed.

What Would We Do Without Peer Review?

There needs to be adequate due diligence, especially when selecting and approaching potential peer reviewers. This shouldn’t need to be said, but the fake peer review cases have thrown up many instances where this hasn’t occurred. I was shocked back in 2012 when the first cases came to light, and now that over 500 retractions due to fake reviews have been reported by Retraction Watch, I’m quite stunned.

The Sound Of Settled Science

This essay by Rupert Darwall explores the expressions of public certainty by climate scientists versus the private expressions of uncertainty, in context of a small Workshop on Climate organized by the American Physical Society (APS). I was privileged to participate in this workshop, which included three climate scientists who support the climate change consensus and three climate scientists who do not–all of whom were questioned by a panel of distinguished physicists. – Judith Curry
