Global warming protest frosted with snow.   When well-meaning people continue to ratchet up the decibel level to try and spur faster action, it tends to become noise.  And when a hot topic becomes the cause of everything - in this case they are saying more snow is a violent oscillation due to global warming - in the minds of most people that means it is causing nothing.

Bringing attention to pollution = good.  Standing on corners preaching the end of the world gets about as much attention as, well, that guy who stands on the corner preaching the end of the world.  

There's a real climate issue to address and it's being addressed, but violent spasms in economies are only okay to people who have time to stand on street corners and protest in the snow.
