Title: Climate Change: Sea Level Rise

Climate Change Sea Level Rise
Herman.Sievering_at_colorado.edu
Associate Scientist,
Global Monitoring Div.
National Oceanic and Atmospheric Admin.
and
Environmental Science Statistics Professor
University
of Colorado
Intergovt. Panel on Climate Change (IPCC)
Member, 2007 Working Group I, The
Science Basis Reviewer IPCC
2013/2014 WGI WGIII reports 

2
CO2 air concentrations over last 60 years,
parts per million
3
CO2 and Methane (CH4) concentrations past
400,000 years
4
Fossil Fuel Carbon Emissions to the Atmosphere
(IPCC)
5
Global Warming ? Climate Change ? Sea Level
Rise (SLR) Some bottom
line SLR bullets SLR likely to displace
5 to 12 million people by 2050 60 to 240
million, perhaps more, displaced by 2100
9 of Florida lost with 1-meter sea
level rise When might 1-meter (3
4) SLR occur??
6
The BIG Three
Heating Expansion of Oceans is, now,
causing about one-half (½) of SLR per
year Glacier Arctic Region melt
1/4th of SLR per year
Greenland Antarctic Melt
1/5th of SLR per year Greenland
ice melt is 480 greater than in early 1990s

SLR How much? How soon?
- Slow, Insidious impact
Mean Global Sea Level Rise (SLR), ft. in.
Year Best
Estimate 2010
8 - measured rapid rate
2030 1 1
2050 1 9 equal to ½
meter 2100
3 4 equal to 1 meter
Range of 2100 Global Mean SLR 2 to 4
__________________ eg 1 SLR payback to
us even if coal oil emissions stop now!

Global Warming ? Climate Change ? Sea Level
Rise (SLR) Some bottom line
bullets if 1-meter SLR by 2100 SLR likely
to displace 5 to 12 million people by 2050
60 to 240 million people may be displaced by
2100 About 1 million homes lost in Florida
- NOT counting the 65 of Floridas

Rise 1 of the NYC 11 surge 11
surge is nearly double previous 300 yr. record
surge By 2100, NYCs SLR will be more
than 1 meter - greater than the 2100
global mean SLR of 2 to 4
3 to 5 SLR for NYC by 2100

Super-storm Sandy and Human-caused Climate
Change 80-90 of 1 NYC SLR (since
1900) is due to we humans Part of 5F
above mean ocean Temp in Sandy-birth-area due to
us Energy uptake along warmer
ocean waters path YES, there was a
human contribution to the
damage caused by
super-storm Sandy!
Impossible to say how much.
Some Solutions after Break

14
Solutions Government Driven
  • Renewable Energy Govt. credits/subsidies
    needed
  • - Renewables subsidy lt50 B-s/yr coal, oil
    gas subsidies gt600 B-s/yr
  • Wind cost less than coal 30-coal-plant
    Chinese farm
  • Solar rapid growth Germany/European Union
    China
  • Geothermal/Hydro/Tidal/other
    underutilized

15
Solutions in Private Sector Insurance-Backgroun
d
  • Insurance Industry largest 7 of Global
    Economy
  • Weather catastrophe payouts up 400 in 2
    decades
  • 40 of total payout funds
  • Munich Reinsurance largest insurer of
    Insurance Co.s
  • concluded - in 1973 -
    there is
  • insurance risk from human-caused climate
    change
  • Those that
    must know, do know

Climate Change activities, 52 countries
UC-Berkeley Study
Insurance Ind. Climate Change funds (since
70s) gt 95,000,000,000

Solutions Insurance Industry (s since
1970s)
  • Climate Change Mitigation Investmt., 24
    Billion s
  • Public Awareness Public Policy Initiatives, 31
    Billion s
  • Financing Client Loss Prevention, Adaptation
    and Climate Change Mitigation Projects, 57
    Billion s
  • - e.g., forest restoration in
    catastrophe-prone areas
  • Climate Science IPCC/Insurer Modeling, 21
    Billion s
  • __________
  • The Greening of Insurance, Science

Mangrove Reforestation, Japanese Insurance Co.
increased resilience to storm damages -
carbon sequestration - company is carbon neutral
since 2008
