the desert research institute in reno, scientists analyzed data from past seasons, and we had the caldor south lake tahoe. they found that mid winter dry spells, burn scars had significantly higher snow melt. >> during these dry periods in the middle of winter, we found that you can lose through melt close to half of the snowpack, if not more in some of the lower elevation places. in places higher in the mountains where we don't expect a big change to take place, even if it's dry, after the fire has passed through that caused snow to melt much faster in those higher elevation areas. >> the impacts of wildfire on snow melt include more sun exposure and a reduction in the snow's ability to reflect sunlight, and in the winter, immediately following a fire, snow is dusted with black carbon from burnt vegetation, which can accelerate snow melt rates. scientists say while extreme weather may be our new normal, we have the ability to adapt, manage and mitigate the impacts. >> how do we deal with fire is through the addition of more fire. we need good fire, low severity, prescribed fire or cultu

kristen: can you explain to us, why is it when we see more wildfires, i'm thinking of the caldor firefor example, what does that do to the landscape, to the area that threatens our snowpack? benjamin: so it does two things in particular. it removes forest canopy by, in some cases, completely combusting all the trees, as you are seeing in some of these photos, and that reduces the abilityoshave the snowck, so its when the snow falls, we get a little bit of snow on the ground, we get a lot more solar radiation or sunlight hitting the snow. the other big thing is all of this burned material, either in the canopy or just the remaining snags or burned trees, burned shrubs, as the winter goes on, the wind knocks pieces of that charred debris onto that snow, and it reduces the snowpack's activity, snow is one of the brightest natural substances, and as we make it darker, it is more easily absorbing the radiation, which is also going up, because we remove the canopy. so it is a two full process that causes snow to melt out more quickly and earlier in the season. kristen: so what happens? what
