Reference :-  Several Sky News anchors have told us that climate scientists are deliberately ignoring the fact that there were hotter days recorded a century ago , hence  their global warming graphs are
meaningless.  This particular Sky Reply is directed at Chris Kenny . He is by no means the only one who informs us so , but he does impart this vital information with a certain flair .

Yes indeed Chris , those scientists  are a sneaky bunch .  They tell us that they only include standardised  temperature measurements taken after the invention of the Stevenson Screen, since earlier measurements  taken without using one are not reliable .  The Stevenson Screen  hasn't received much mention on Sky News has it  Chris ?  But then again , why make a story complicated ?     Who cares if we now take temperature recordings from a thermometer shaded and ventilated in one of those white screens , whereas  back in the day they might just stick a thermometer on a tin can in the sun and try to outdo their neighbors for the hottest day .
 That's the trouble with science , too many variables to deal with . Like you , Chris , I reckon you cant go wrong keeping things simple .  KISS as they say .  

 Your comrade , Ken.
