The implications of climate change?
The implications of climate change will depend on the level of climate change and vulnerability:
The level of climate change depends on mitigation
Vulnerability depends on resiliency and adaptation investment

The Challenge – shifting global emissions trends to stabilize/reverse climate change
AR5 430-530 ppm CO2e pathways are consistent with staying below 2˚C with 40% or better likelihood.
2025-2030 10th – 90th percentile window is ~25-60 GtCO2e.
The window for staying below 2˚C with 40% or
better likelihood

Not on track for staying below 2 degrees Celsius without greater reductions beyond 2030
“Assuming the proposed cuts are extended through 2100 but not deepened further, they result in
about 0.2°C less warming by the end of the century…”

An important issue: mitigation policy design
Options for U.S. INDC Implementation
1. Sectoral – primarily regulatory
2. National (economy-wide)
3. International cooperation (bi- to multi-lateral)
Not all equal

The regulatory approach precludes…
1. Realization of lower cost cross-sectoremissions reduction opportunities
2. Realization of lower cost internationalemissions reduction opportunities
3. Cost-effective long-run mitigation investment

Energy implications? Tier of perspectives needed.
Tiers of potential risk (and analyses)– Facility– System – Sector– Energy system– Economy– Other societal impacts
Direct sector risks (e.g., generation, distribution, load)
Direct risk implications & Indirect risks (e.g., energy markets, demand relocation)

Preventive
Restorative (response strategies)

Need to characterize risk and return on investments – but challenging

Concluding thoughts
Some degree of climate change is inevitable
We need to better characterize the risk to make informed response decisions– Can't avoid all risk and probably do not want to
There are emissions mitigation opportunities, but policy design matters– Aggressive climate action requires looking beyond sectors, borders,
and 2030
There are adaptation possibilities, but which make sense?
