The link was made by the poster not the meteorlogical group. Pluto just finished its closest approach to the sun a few decades back and it is quite likely to have some long term effects due to that just as Earths hottest temperatures tend to occur after the longest day not on it. That's easily two independent events.

A for Mars

"Caplinger and lead author Michael Malin, also of Malin Space Science Systems, suggest that the dwindling layers of frozen carbon dioxide could be sublimating (changing from solid to gas the same way ice cubes shrink over time in a freezer) and contributing carbon dioxide gas to the Martian atmosphere.

More carbon dioxide gas in the air would create a denser atmosphere. And a denser atmosphere insulates the planet and leads to warmer temperatures and higher evaporation points for carbon dioxide and water. "

Another sound case for rejecting CO2 based global warming I see. You guys looked real hard for that one. I guess the fact that they didn't specifically mention the greenhouse effect of CO2 threw you for a loop.
