Nikki warned that we are increasing global CO2 emissions by 2-3ppm (parts per million) per year and our current emissions are at 411.21ppm. She stressed that with 450ppm being considered commensurate with 2°C, urgent action is needed.
3. Are sea levels rising?
Antarctic ice melt tripled last 5
years
4. February 2018 Nat Academy of
Sciences report
Fed gov’s Climate Assessment Report
• sea level rise accelerating
as thermal expansion & ice melting
likely rise of 15 – 35cm by 2050 and 30 –
120cm by 2100 – could be as high as 2.4m on
high emission path – rising by
1cm / year by 2100
•
10. CO2 in Seawater becomes Carbonic Acid:
pH of our oceans has dropped 30% since
1990
13. When do we reach 1.5°C warming?
• Current global average 1.15° warmer
• United Nations Environment Programme says we
have 2 years approx to make decisions to stay
below
• IPCC putting out special
report on 1.5° in 2018
14. When could we reach 2 degrees?
• Next 5 – 10 years to make decisions…
•
• 2035? 2040?
• Already discussion of
over-shooting…
•
18. The World is Changing…
• Changing economics of energy
• Public pressure on fossil fuel companies
• The world of finance is changing
• Government regulation / policy
• New technology
• Corporate & consumer pressure
•
• Focus is on energy – but don’t forget land use
– cement is 5%...
19. Does UK consumption matter?
• Only 1 – 1.5% of total
• But responsible for much of what active now
• Basis of Paris agreement
•
• Still 6th biggest economy – multinats are 50%
-can change economics, political and social
culture
• We all have to face ourselves…
24. Some surprising trends….
• Fuel consumption on long term decline, (1.8% /
yr) despite growing population and economy -
expected to reverse 2025???
• Commitment to ending all coal fired power
production by 2025
• Significant strides for renewables in power
production (but not in heat or transport)
• Significant drops in greenhouse gas emissions
(but not enough for Paris / UK commitments)
•
32. So….
• UK consumption of fuel not going down as
figures suggest
•
•
• But declining consumption within UK borders
is context for energy policy
34. Global target….
•
• To stay below 2°C warming compared with
pre-industrial times. Preferably closer to
1.5°C. We are already at 1.5°C in UK.
• To peak global greenhouse gas emissions no
later than 2020 and to cut back rapidly from
there.
35. The UK’s emission targets
• 35% reduction in greenhouse gas
emissions by 2020, from 1990 level
• 80% reduction in greenhouse gas
emissions by 2050, from 1990 level;
50% by 2025, 57% by 2032
• 100% by 2100
• Paris : 100% by 2050
37. Unlikely to meet Climate Change
Act budgets without ‘flexibilities’
• Carry forward over-achievement from
previous budgets
• Borrow from later budget (1% max)
• Use International Carbon Credits
• Committee on CC: urgent repeal of ban on
onshore wind, tax company vehicles & zero-
carbon homes
38. David King’s legal
challenge…
• Under Paris, UK committed to 100% reduction
by 2050 – but haven’t enshrined in Climate
Change Act – now considering
• ‘The science has clearly hardened since the
Climate Change Act was agreed…our current
course takes us to catastrophe, then to stick
to current course is irrational…The best
available science tells us the risks of crossing
tipping points rise very sharply between 1.5
and 2 degrees…’
39. Need to cut 2 – 3% every year till
2030 to meet 5th carbon budget
44. Coal could come back…
• Currently £23/tonne carbon price – fixed till
2020
• Currently in European Trading System…..
• Need £40/tonne to keep coal off grid as coal
price likely to drop, gas to increase
• Surge in corporate planning for cost of carbon –
another 782 companies planning internal
price by 2019 - but opening new mines….
45. Biomass – we don’t count the
emissions…. Nor the full LCA of gas
46. More can be done….
• Scotland – 68.1% renewable
electricity in 2017
• Wales – 43% plus
•
• Northern Ireland aiming 40% by
2020
47. What’s in the Clean Growth Plan?
• More nuclear, more gas
• Commitment to off-shore wind till 2025
• Renewed commitment to carbon capture and
storage
• Promotion of EVs
• Insulation in homes
• Heat pumps and hydrogen
• But complete drop in hydro, solar, onshore
wind, no tidal or pumped storage.
• More waste-to-energy & biomass.

June: Antarctica ice melt has put up sea level by 0.8mm since 1992, a fifth of this since 2012– rate of loss has tripled in last 5 year… - Carbon BriefThird of 20 C sea level rise is from Greenland melting - Over the period 1901 – 2010, global mean sea level rose by 0.19m.

Representative Concentration Pathways – to stabilise need to make emissions negative – effects now are already irreversible over millennia = even in best scenario will take us centuries to get below 350 degrees
Gas down 2 in 2018, oil steady, coal at 9, rens at 22 Gas figures from Nat Grid Future Energy Scenarios

Partly because takes so much energy to make electricity and get to us. Highest emissions no longer true. But big pressure on this sector to help decarbonise others…
A lot of pressure on power sector… but mustn’t forget other two…
