                             A  CONSPIRACY  SO  VAST . . .

As global warming proceeds a picokelvin at a time, what ever will 
 Watts'  fans make of  plans to redefine the whole bloody degree?
Cue indignation from the usual suspects.

Advances in thermometry

The past 25 years have seen tremendous progress in thermometry across the moderate temperature range of 1 K to 1,235 K. Various primary thermometers, based on a wide range of different physics, have uncovered errors in the International Temperature Scale of 1990, and set the stage for the planned redefinition of the kelvin.
Nature Physics
Rather than fixing the scale at  the  triple point of water,  
The  International  Committee for  Weights & Measures  
now recommends using the energy equivalent given by Boltzmann's equation .

Current definition:
The kelvin, unit of thermodynamic temperature, is the fraction 1/273.16 of the thermodynamic temperature of the triple point of water.

Proposed redefinition: 
The magnitude of the  kelvin as the unit of thermodynamic temperature is to be set by fixing the numerical value of the Boltzmann constant to be equal to exactly 1.38065X×10−23 when it is expressed in the unit s−2·m2·kg·K−1, which is equal to J·K−1.
