Climate change: Five things we know
1.
The Earth is heating up – rapidly
2.
Human emissions of CO2, other gases, are the dominant cause
3.
Changes will continue and probably accelerate
4.
Impacts?
•
•
5.
Diverse, Variable, Uncertain, Less well understood
Plausible outcomes range from “no big deal” to “civilization-threatening catastrophe”
Most recent new is bad … Disconnect between popular perception and
reality is vast and growing.
Scientific uncertainties: Real, some large, but DO NOT undermine
these points
Recent political attacks on climate science have raised NO points that
deny or significantly modify this knowledge
What to do about it? Three types of response
• Limit climate change by reducing net emissions
• Adapt to changes we can’t avoid by reducing
vulnerability
(and back on the agenda after a long absence …)
• Engineer the Climate: modify global processes
to unlink emissions and climate change.
1. Limit climate change by cutting emissions
A global problem: Must limit world emissions
A century-scale problem: Start now, sustain through slow
transition to non-fossil energy system: Steering a supertanker
Many feasible options, available and in the pipeline
(All needed – no magic bullet, no pre-exclusions)
Innovation not enough – need massive deployment
Not enough “no regrets” options – Need Incentives from
policy and law
How much must we cut to limit risks?
Avoid most severe impacts of climate change
~↓
(approx expert judgments)
Limit global-average Δ T to ~ 2 º C (now ~ 0.8)
~↓
(~ 50% chance)
Limit atmospheric GHGs to ~ 450 ppm CO2-eq (now ~ 400)
~↓
(pretty confident)
Cut world emissions 50 – 85% by 2050
~↓
(political judgment and bargaining)
Cut emissions in rich countries at least 80% by 2050
Policies to Achieve Emission Cuts
• Economy-wide measures to put a price on emissions
• Emission taxes, tradable permits, or combinations
• Start modestly, increase stringency over time –clear signal to new investment
• Support for energy R&D
• Targeted sectoral measures
• Where energy market incentives are weak
• For large near-term targets of opportunity
• Large government decisions: e.g., infrastructure,
• Plus … processes for adaptation and learning as we go
International Climate Law
Major landmarks
•
Framework Convention (1992)
•
Principle of Common but Differentiated Responsibility
• Defined “Annex 1” countries (ICs plus former Soviet bloc)
•
Kyoto Protocol (1997)
•
•
•
Modest near-term emission limits for Annex 1 countries
Defined on basket of 5 gases, 2008-2012
Compliance range: from squeaker (EU) to train wreck (Canada)
International Climate Law
Recent efforts
•
Bali (2007)
•
•
•
Copenhagen (2009)
•
•
•
First undertaking for mitigation “actions” by non-Annex 1
Two negotiating tracks: Kyoto (for parties), LCA (for all)
Deadlock, procedural blockage (again)
Last-minute political accord – significant advances, but far short of need
Post-Copenhagen fizzle: Cancun, Durban, Doha, Warsaw (starting today)
•
•
•
•
Durban program: negotiate new instrument by 2015, in force by 2020
Doha: establish (fictitious) KP 2nd commitment period, abolish two Bali tracks
Overt collapse avoided each year, but ~ zero progress
Prospects so dim, Saudi Arabia has refrained from further procedural obstruction
The Current Deadlock: Summary
UNFCCC/Kyoto Process: Universality + formal procedures +
consensus decision-making = deadlock
National Actions:
•
•
•
•
•
•
US: Legislation blocked since 2010, no current prospects
Executive action: EPA regulation under Clean Air Act, etc.
EU: Early leadership, strong targets, implementation failure
Signs of strong action in emerging economies, esp. China
Sub-national: California, British Columbia, Regional efforts
Nothing remotely proportional to the needs
Science:
• IPCC – New assessment coming, influence declining
• Political campaign against climate science is winning
Dangerous “New line” in debate (not new)
• “Tech Breakthrough” school without incentives – magical thinking
Ways Forward?
Shift from UN Universality back to Great-Power Diplomacy?
•
Old heresy ~ new consensus: 12 to 20 at the table: Major Economies,
G8+5 – G-20
•
Long-standing informal practice in larger forums (until Copenhagen)
•
Several Track II exercises mapped potential “global bargain”
•
Needs: Heads of Govt, broad agenda, institutional continuity, support
•
Biggest challenges: burden-sharing, implementation and MRV
•
Reality-check: Promising direction, but no serious action yet in these
Attention-forcing event:
•
•
•
Serious debate on Geoengineering:
•
•
More evident disruptions More pressure for Action
But what type of event? (Nothing so far has done it)
With what result: Flip from nothing to panic, search for blame?
Wild-card: Politically toxic now, may be essential
Big benefit, big risk: Will need international governance
The Chinese Solution:
•
•
Chinese Empire solves the problem in 50 years
Our fecklessness (on this and other issues) has made us irrelevant
Ways Forward?
Private “smart-money” leadership
• Not enough by itself … but might set off virtuous circle: what
innovations can get toe-hold, expand rapidly enough?
• Most likely: some technologies grow rapidly, some people get very
rich, but small contribution to problem (but what’s the
alternative?)
Small policies (California, etc.)
• Not enough … but might set off a virtuous circle
• Interaction between small policies and smart-money leadership –
more promise than either alone
Serious action by a small group (2 to 20)?
Three Challenges
•
Allocation of efforts, burdens within group
Any viable group will include wide GDP/cap range
• Burden-sharing can be implicit but can’t be avoided
•
•
Monitoring and verification of commitments
•
•
Sharpest conflict, most progress at Copenhagen
Emissions leakage
Policies raise costs Energy-intensive production moves
• Lose competitiveness and employment, weaken envt goal
• Size, speed may be over-stated, but still real concern
•
Response to Emissions Leakage
•
Make the group bigger
•
Embed incentives for rapid expansion
•
•
Anticipated expansion weakens incentive for investment shift
Enact border adjustment measures
•
Assess embedded emissions in traded goods
•
Charge equivalent policy burden on imports, Rebate on exports
•
Easy for fuels, harder for emissions-intensive products
•
In US legislation, EU proposals
•
WTO-permissible?
•
•
•
•
•
Not yet attempted, challenged, or adjudicated – but probably …
Easier in context of MEA (how many?)
Depends on form of policy (Carbon tax, Cap-trade, Sectoral?)
No trickery in design or implementation
Procedural recourse
Extra Slides
Atmospheric CO2: Direct measurements since 1958
The Earth is heating up: 100-year history
(NASA GISS)
Recent heating in 2000-year context
(Copenhagen Diagnosis, 2009)
Northern Hemisphere reconstructed temperature change since 200AD
Projected Temperature:
Next 100 vs. Past 1500 years
Emission Scenarios for Stabilization
2. Adapt to Unavoidable Changes to Limit Harm
A Multi-scale problem, from local/regional to global
Ironies of adaptation:
• Long-standing conspiracy of silence
• Common presumption it’s easier – with no evidence
Adapting, Limiting are Linked: Limit less Must adapt to more
Necessary, sure … but Easy?
• Current evidence – Mal-adaptation even to current conditions
• Serious adaptation – Multiple hard legal/political problems
Build robustness to variable conditions Higher costs
Zoning, Planning, other limits on development
Manage and pool risks: Public insurance, emergency prep, public health
Reducing vulnerabilities: Resource transfers, domestic and international
3. Engineer interventions to limit climate change
• Two ways: alter Carbon cycle, or Sunlight – High vs. Low leverage
• Fast: Cool Earth ~ 1 year, vs. decades for mitigation or C-capture
• Cheap: Offset 21st-C heating for ~ $Bn/year, dropping – call it zero
• Imperfect:
Direct environmental harms (the least of the problems?)
Imperfect climate offset:
• Global-average: Temperature vs. water
• Regional and seasonal effects
• Achieve regional tuning? Oops, it’s a weapon
Non-climate effects of CO2: oceans, ecosystems
• Sharp dilemma: Raise big new risks, but we might need them
• Governance and control? Severe challenges to Law and Institutions
How to cut emissions this much?
•
Transform world energy system to climate-safe sources in ~ 100 years
•
Climate-safe technologies? the usual suspects
•
Available now (but much room for advances)
•
•
•
•
•
More distant prospects (but plausible over decades)
•
•
•
Efficiency (huge room for improvement)
Renewables (incl. biofuels and geothermal)
Nuclear fission
Carbon capture and storage (extends usable lifetime of fossil fuels)
Space solar
Nuclear fusion
Cost?
•
•
Stabilize 450 ppm: ~ 1-10% future loss (from baseline 7-15X real growth by 2100)
Marginal costs: ~ $200-2,000 per tonne Carbon
Climate Change Response:
Framework Convention on Climate Change (1992)
~ All nations are parties, including USA
Ratified by Bush Sr. administration
Broad structure for subsequent management, no concrete
commitments
Objective: “… stabilization of greenhouse gas concentrations in the
atmosphere at a level that would prevent dangerous anthropogenic
interference with the climate system … ”
Various Principles, including “Common but Differentiated
Responsibility”
Defines classes of parties (mainly Annex 1 vs. non) for distinct
obligations – a rigidity now problematic
Weak hortatory target for Industrialized countries: back to 1990
emissions levels in 2000 (almost none met it, no consequences)
Climate Change Response:
Kyoto Protocol (1997)
1995 Berlin mandate set agenda: QERLOs for Annex 1 Parties as first
step
~ 190 parties (USA only significant non-Party)
Key implementation questions resolved in Bonn (2001)
Entered into force Feb 2005, after Russian rat’n achieved 55% threshold
Binding emission targets for developed countries, avg. 5.2% below 1990
• EU 8%, Japan, Canada 6%, Russia 0%, USA 7%
• Defined over 2008-2012 commitment period
• For weighted “basket” of 6 greenhouse gases
Flexibility mechanisms: What, when, where – US pushed
Emissions trading – Concern with Russian “hot air”
Domestic implementation not specified; Self-reporting of national
performance
Kyoto Protocol:
Progress and Problems, 1997-2007
Hypnotized by numbers, last-minute horse-trading (incl.
reversal of domestic deals in US, Canada)
Key implementation issues deferred – mostly resolved 2001,
but …
• Substantial weakening
• Lost the US (if they ever had it), no chance for re-engagement
Late entry into force, political weakness: Most will miss 1stround targets
• Formal success overall depends on massive credit from Russia “hot
air”
Targets: too strong now (high costs), nothing long-term when it
matters
~ No progress on further cuts post-2012: negotiations
obstructed by front-loading debts from 1st-round exceedence
~ No progress engaging Developing Countries on future
emissions commitments
until Bali, 2007 …
Bali Mandate, 2007:
(Episode IV: A New Hope?)
Major DCs: First acceptance of responsibility for
action
New structure to negotiate commitments: IC
“commitments” vs. DC “actions” – First step to reengage USA
Two tracks to Copenhagen: AWG-LCA and AWG-KP
But … (Episode V: The Empire Strikes Back?)
Immediate return to deadlock: Tracks separate or
linked?
No progress through mid-2009, lowering
expectations:
Copenhagen 2009:
Revealing the Limits of Universality
Key Issues:
•
•
•
•
•
Further IC emission commitments
DC mitigation actions
Short and long-term finance
Governance structures
Misc issues: REDD, bunkers, etc.
Proposals for new Protocols Procedural blockage
Informal groups – progress only on REDD (solvable with $)
“Danish text” proposals angrily (disingenuously) rejected
Last-day head-of-govt negotiations: 5 nations, then 28
“Copenhagen Accord”
Copenhagen Accord
Another non-binding “political agreement” (as expected)
Several significant advances:
•
•
•
•
•
Sought, but missing:
•
•
•
Explicit statement of existing IC 2020 targets
Date of peak global emissions, explicit target for DCs
MRV: “Unsupported” DC actions have only domestic MRV, with “International
consultation and analysis”
Intense final-night plenary:
•
•
•
•
States 2°C warming target
Emission cuts to do this: 1990 – 50% globally by 2050, “at least 80%” by ICs
Careful provisions for MRV (biggest US-China conflict, biggest advance)
Large increase in $: $10B/yr, 2010-2012, $100B/yr (multiple sources) from 2020
Review by 2016: Consider tightening target to 1.5°C
Denounced by several nations (incl Sudan, probably China proxy) – blocked adoption
“Took note” – Individual registration of support, commitments (most big have)
Status as basis for future negotiations – to be contested
Broader negotiations under FCCC and KP tracks remain blocked
Follow-up:
•
•
~ 140 nations “indicated support” for Copenhagen accord
~ 80 “provided info on” emission reduction targets or other mitigation actions (Nothing
new)
Cancun 2010
Reprise of conflicts, obstructions, from Copenhagen (at lower
volume)
Relationship between KP (rich) and LCA (everyone)
• Japan “bombshell”: Won’t
Inscribe its existing commitments in amended KP Annex B
Accept decision to extend first KP commitment period or establish a second
I.e., Merge the tracks, discuss commitments for everyone together
DCs have consistently refused in FCCC/KP discussions
Issue by Issue: progress and importance perfectly correlated
(negative)
• More promising: Adaptation, technology, capacity-building
And REDD … (Remains a N-S conspiracy to fake progress)
• Less promising: Mitigation, Finance, MRV, Legal form (all the big ones)
• Maybe we’ll get HFC controls under the Montreal Protocol …
How dim are the prospects?
• So dim, Saudi Arabia didn’t bother to exercise its usual procedural
obstruction
Managing Climate Change:
Easy or Hard? A Paradox
Easy:
• Not the end of rich industrialized democratic societies
• Just (mostly) a technical problem: how we get, convert, and
use energy
• Cost of major (not total) risk reduction:
~ 0.1 – 2% loss of future (very high) GDP
Hard:
•
•
•
•
•
Scientific uncertainty and disagreement …
Which can’t readily be characterized in decision-relevant terms
And which is widely subject to partisan misuse
E.g., What’s the probability distribution of climate-sensitivity?
Inability of science (alone) to define “policy-relevant”
questions
• Distribution of costs – Losers (thus far) able to block
• Ability to deploy ideology and symbolism to resist change
(especially but not exclusively in the US)
