ELI5:What do they mean when they say the mass of the atmosphere of Pluto has decreased by a factor of 2 in two years?

What exactly does that mean? Does it affect the already low gravity? If set upon said data and put onto a scale, what would the planet be like in 25 years? 100?

Uhhhh, Pluto is heading into it's hundred year 'winter' season.  The atmosphere is freezing to the planet as ice.  It's a 'dwarf' planet equivalent of a comet (sorta).  Everyone saying it's lack of gravity is missing the fact that that process takes eons, not two years.
