Note the step change. At about 1960, the uncertainty levels plummet, meaning BEST is claiming we became more than twice as certain of our temperature estimates practically overnight.

BEST practices step uncertainty levels in their climate data

Brandon Shollenberger writes in with this little gem: I thought you might be interested in a couple posts I wrote discussing some odd problems with the BEST temperature record.  You can find them here: http://www.hi-izuru.org/wp_blog/2015/01/how-best-overestimates-its-certainty-part-2/ http://www.hi-izuru.org/wp_blog/2015/01/how-best-overestimates-its-certainty-part-1/ But I’ll give an overview.  BEST calculated its uncertainty levels by removing 1/8th of its data and rerunning its…

Although the framework often characterizes climate change as a negative and disruptive phenomenon, the framework clearly states students need to understand all the factors causing climate change writing, “Natural factors…
