How Will Global Warming Impact California?

IPCC
Emissions Scenarios

Summary of Projected
Global Warming Impacts
(2070-2099, as
compared to 1961-1990)

State-wide Temp-erature Rise

Higher
Emissions:
Rapid,
fossil-fuel intensive
growth
  • 90% loss in Sierra snow pack
  • 22-30 inches of sea level rise
  • 3-4 times as many heatwave days in major urban centers
  • 2.5 times the number critically dry years
  • 4-6 times as many heat-related deaths in major urban centers
  • 20% increase in electricity demand
  • Increase in days meteorologiclaly conducive to ozone formation

 

Higher Warming Range:
8-10.4 ºF

Medium-High
Emissions:

Primarily
fossil-fuel dependent growth with some green technology
  • 70- 80 % loss in Sierra snow pack
  • 14-22 inches of sea level rise
  • 2.5-4 times as many heatwave days in major urban centers
  • 2-6 times as many heat-related deaths for major urban centers
  • 75-85% increase in days meteorologically conducive to ozone formation
  • 2-2.5 times the number critically dry years
  • 11% increase in electricity demand
  • 30% decrease in forest yields (pine)
  • 55% increase in the expected risk of large wildfires

 

 

Medium Warming Range:
5.5-
7.9 ºF

Lower
Emissions:
Shift to
service
& information economy
with lots of green technology
  • 30-60 % loss in Sierra snow pack
  • 6-14 inches of sea level rise
  • 2-2.5 times as many heatwave days in major urban centers
  • 2-3 times as many heat-related deaths for major urban centers
  • 25-35% increase in days meteorologically conducive to ozone formation
  • Up to 1-1.5 times the number critically dry years
  • 3-6 % increase in electricity demand
  • 7-14% decrease in forest yields (pine)
  • 10-35% increase in the risk of large wildfires

 

 

Lower Warming Range:
3.0-5.4 ºF
