  • George Rebane Now here’s a report by some people from the mother temple of global warming that is guaranteed to summon the Left’s crickets.  More cool-headed scientists have been reporting on the new cooling trend that correlates with low sun-cycle activity for years now.  This has been echoed and amplified on many serious websites (e.g.…

  • George Rebane [This is the transcript of my regularly scheduled KVMR radio commentary broadcast on 30 January 2019.  An edited version of this commentary appeared in the 2feb19 Union.] Standby for the next tranche of earthshaking news.  You know, the kind of report that promises to make a big impact on the lives of each…
