Transcript

  • 1. a100%renewable future
  • 2. “When I look at this data, the trend is perfectly in linewith a temperature increase of 6 degrees Celsius ,which would have ……devastating consequences for the planet.”“We have 5 years to change the energy system……or have it changed” Fatih Birol IEA Chief Economist
  • 3. Things are getting worse! Global CO2 emission trends?~ 2.7% p.a. last 100yrs~ 3.5% p.a. 2000-2007~ 5.9% 2009-2010~ 3.2 % 2010-2011(A1FI has mean growth of 2.2% p.a. to 2020)
  • 4. The State of Play“To hold the increase in global temperature below2 degrees Celsius, and take action to meet this objectiveconsistent with science” Copenhagen Accord (2009)Committee on Climate Change global budget has56% chance of exceeding 2CUK Government adopts a pathway with a63% chance of exceeding 2C
  • 5. The ChallengeUK’s target: 80% reduction in CO2e by 2050EU 60%-80% 2050Bali 50% 2050 CO2 stays in atmosphere for 100+ years 2050 reduction unrelated to avoiding dangerous climate change (2°C) It is cumulative emissions that matter (i.e. carbon budget) This fundamentally rewrites the chronology of climate change - from long term gradual reductions - to urgent & radical reductions
  • 6. The Challenge“… it is difficult to envisage anything other than aplanned economic recession being compatible withstabilisation at or below 650ppmv CO2e.” Anderson & Bows 2008
  • 7. Total Greenhouse Gas Emission Pathways AR4 – 450ppmv CO2e stabilisation cumulative emission range 2015 peak 2020 peak 2025 peakEmissions of greenhouse gases (GtCO2e) 80 Emissions of greenhouse gases (GtCO2e) Emissions of greenhouse gases (GtCO2e) 80 80 Low DL 60 Low DH 60 60 Medium DL Medium DH High DL 40 High DH 40 40 20 20 20 0 0 0 2000 2020 2040 2060 2080 2100 2000 2020 2040 2060 2080 2100 2000 2020 2040 2060 2080 2100 Year Year Year Anderson & Bows. 2008 Philosophical Transactions A of the Royal Society. 366. pp.3863-3882)

  • 9. a100%renewable future
  • 10. Anderson-Bows: (CO2 only)(Royal Society’s Philosophical Transactions – Jan 2011 ~40% chance of exceeding 2°C)
  • 11. Anderson-Bows: (CO2 only)(Royal Society’s Philosophical Transactions – Jan 2011 ~40% chance of exceeding 2°C) Peak 2025 Growth 3.5% p.a Reduction 7% p.a. (2x Stern!)
  • 12. Anderson-Bows: (CO2 only)(Royal Society’s Philosophical Transactions – Jan 2011 ~40% chance of exceeding 2°C)
  • 13. Anderson-Bows: (CO2 only)(Royal Society’s Philosophical Transactions – Jan 2011 ~40% chance of exceeding 2°C) Peak ~2010 Reduction ∞% p.a.
  • 14. The Problems All scenarios showing avoidance of dangerous climate change use Bio-carbon capture and storage to give negative emissions (geoengineering) Most scenarios showing avoidance of dangerous climate change use a large expansion of nuclear power Assumptions about ‘big’ technology naively optimistic Recent historical emissions massaged Short-term emissions growth seriously downplayed Reduction rate universally dictated by economists Annex 1/Non-Annex 1 split neglected or hidden Senior Government Advisor: “We can’t tell [ministers and politicians that 2oC is] not possible”
  • 15. And 4oC? Emissions must peak no later than 2020 A 3.5% pa reduction in energy emissions is imperative At least it’s achievable…
  • 16. The Downside For 4°C global mean surface temperature 5°C - 6°C global land mean And an increase on the hottest days of:  6°C - 8°C in China  8°C - 10°C in Central Europe  10°C -12°C in New York And in low latitudes 4 C gives up to 40% reduction in maize and rice as population heads towards 9 billion by 2050
  • 17. The SituationThere is a widespread view that a 4°C future isincompatible with an organised global communityis likely to be beyond ‘adaptation’is devastating to the majority of eco-systemsand has a high probability of not being stable (i.e. 4°Cwould be an interim temperature on the way to a muchhigher equilibrium level).Consequently… 4°C should be avoided at all costs
  • 18. Energy Emissions 10% reduction year-on-yearImpossible?Approximately 50% of emissions caused by 1% of globalpopulationIncluding *probably* everyone in this roomAnyone who ever sets foot on a planeAnyone in the UK earning over ~£30k
  • 19. And Wales?
  • 20. Wales leading the way“Wales is a definite leader inpromoting sustainabledevelopment”
