There are bones hidden away in almost every cupboard in many of the rooms of New York University’s primatology department, and James Higham is keen to explain to me what they can tell us about an important part of our evolution: why we have such big, heavy brains.

Yours truly has a preference for spuds over rice as the dietary “carb.” So, you may forgive me for being interested in news about this tuber-kind being potentially feeding the future colonists on planet Mars.Surely now, our venerable Canadian Broadcasting Service (CBC) would not lie!
As the report says:
The [potato growing] experiment was conducted in soil in the Atacama Desert in Peru, which is…

Josh writes: On this historic Brexit day the fun has not been confined to this continent. Over in the US they have had a ‘hearing’ on Climate Science with three of the world’s most eminent climate scientists. Michael Mann was there too.

Beleaguered Models: Harvard Physicist/New Study Say Daily Insolation Errors Not Accounted For!

Beleaguered Models: Harvard Physicist/New Study Say Daily Insolation Errors Not Accounted For!

A new paper is out by Rodolfo G. Cionco and Willie W. H. Soon: “Short Term Orbital Forcing (STOF): A quasi-review and a reappraisal of realistic boundary conditions for climate modeling“.

It suggests that climate models have neglected to take surrounding astro-climatic parameters correctly into account, and thus their output results are likely even less reliable.

The abstract above states that the two authors found “important relative differences of up to +- 5%, which correspond to 2.5 W/sqm in the daily mean insolation“. They conclude: “this previously unrecognized error could have a significant impact in initial and boundary conditions for any climate modeling experiment.”

Willie Soon, a Harvard astrophysicist and skeptic of AGW science, wrote in an email:

To our best understanding, this new insolation calculation should supersede/replace the previous outputs provided by Berger & Loutre (1991) and Laskar et al. (2004) and their related publications especially since all these previous calculations/databases have not accounted for the modulating effects from STOF. “

The scientists summarize in the paper that the error “could spread and propagate with time especially when intra-annual insolation quantities are required” and that “the sensitivity of initial climate conditions to these differences should be addressed“.

In other words: it’s back (again) to the drawing board for the beleaguered climate modelers.
