Future Snowpack Losses Under High Warming

Projections of Snow Water Equivalent (SWE) Losses - SSP5-8.5
cryosphere NASA VEDA COG
In plain English

What it measures. Shows the projected percent change in snowpack (water stored in snow) versus the 1995-2014 baseline, under a high greenhouse-gas scenario. It maps where mountain snow is expected to decline most steeply.

How it's made. Made from NASA computer simulations driven by downscaled CMIP6 climate-model projections (the SSP5-8.5 scenario).

How & where you'd use it. Helps water managers and communities plan for a future with far less snow-fed water.

Official description

Percent-change to future SWE, relative to the historical period (1995 - 2014), simulated using the LIS framework and CMIP6 climate projections (SSP5-8.5 scenario) downscaled by NASA Earth Exchange (NEX-GDDP-CMIP6)
