Scientists have generally attributed that darkening to larger, slightly less white snow grains caused by warmer temperatures.
Actually I cannot believe that scientists are that stupid. Maybe they should visit here in Winnipeg Canada where we see this every year from the tonnes of sand they put on our streets in the winter. As warmer temps rise the snow banks go from white piles to brown/grey mud piles and as more snow melts the darker it gets and the faster it melts.
No wonder people doubt climate change when scientists say things like this.
The only thing that can reduce it is if the melt water floats/washes the impurities way.
Actual in 90% of the time this is not the case, we get rain in the spring with the piles of mud and all it does is causes the snow pack to compress more (unless the snow pack is already compressed).
You realize that there are private companies that collect *way* more information about you than the NSA does and they sell it to whomever wants to buy it.
Oh wait I forgot this is
Sorry move along...
