Warmer atmosphere effect on precipitation
Warmer atmosphere effect on precipitation
Holds more water vapour = more precipitation
Warmer temps effect on evaporation rates
Warmer temps effect on evaporation rates
Higher rates of evaporation
Climate change effect on rainfall intensity
Climate change effect on rainfall intensity
Rainfall likely to have greater intensity
High latitude precipitation change (climate change)
High latitude precipitation change (climate change)
More likely rain rather than snow
Why glaciers decrease in size (climate change)
Why glaciers decrease in size (climate change)
Less accumulation, more melting - disappearing faster
Climate change effect on spring snowmelt timing
Climate change effect on spring snowmelt timing
Spring snowmelt will begin earlier
Permafrost thawing effect on carbon/warming
Permafrost thawing effect on carbon/warming
Methane release → ↑ carbon stores & warming
Soil moisture changes from climate change
Soil moisture changes from climate change
Likely unchanged (precip. & evap. cancel out)
Runoff & streamflow variability changes
Runoff & streamflow variability changes
More floods & more periods of low flow
