impacts of climate change on the hydrological cycle |
increased water holding capacity of the atmosphere increased evaporation due to warmer seas increased precipitation/hurricanes/storms increased el niño freq increased drought - ITCZ failure decreased cryosphere store - loss of glaciers/melts earlier |
|
|
colorado river water supply |
reduced river discharge why increased usage population growth climate change- warmer - increase evap over abstraction for LA, Vegas etc agricultural purposes lake mead co |
|
|
lake mead- colorado river |
only at 27% of capacity water level fell 40ft since 2000 |
|
|
water quality |
heavy precipitation- could overwhelm sewage systems coastal freshwater sources could experience salt water incursion |
|
|
change in precipitation |
monsoon failure droughts due to el niño la niña |
|
|
stores |
glaciers- cryosphere decreased, melt earlier in spring reservoirs/lakes- decreased store + precipitation, increased evap e.g lake mead permafrost- decreased store, releases co2/methane |
|
|
flows |
runoff/streamflow- increased precipitation, increased soil moisture increased surface runoff |
|
|
why is there uncertainty about global warming |
continued use of fossil fuels ? use of renewables volcanic activity increased population growth of middle class/nutrition transition global agreements positive feedbacks loss of peatland unknown rates of deforestation/afforestation |
|
|
southern oscillation |
