Climate change consequences Climate change consequences

Assuming "BAU" (4°C to 6°C by 2100) 1 metre sea level rise (conservative estimate) Changes in weather: Wetter/drier weather in some regions Increase in extreme weather events (cyclones, heat waves, storms) Ocean acidification

Mass migration Health problems Disruption of food production Resource scarcity (especially fresh water) Social instability and war

To summarise To summarise

We've known about climate change for a long time The effects will be catastrophic So... why haven't we done more???

Why haven't we done more? Why haven't we done more?

How far away are we from doing "enough"? What have we done so far? What do we need to do? Who or what do we mean by "we"? Who is actually making the decisions?

Paris Agreement Paris Agreement

Agreement in 2015 to limit warming to 1.5°C "Nationally determined contributions" (NDCs) Submitted every 5 years (next one due 2020) Voluntary emissions targets

Paris Agreement Paris Agreement

Good: 196 countries agreed (almost all have ratified) Measurement of current targets Bad: It's voluntary / non-binding Commitments not ambitious enough

Summary - what have we done? Summary - what have we done?

Emissions continuing to rise Falling in some countries Partly due to moving production offshore Partly due to rise in natural gas use Paris Agreement not working (well)

What do we need to do? What do we need to do?

Keep warming to 1.5°C (or at most 2°C) Reduce emissions Social policy

What do we mean by "we"? What do we mean by "we"?

Everyone! ...but maybe not equally? Who is responsible for most of the emissions? Who is in the best position to lead action?

Who can make changes Who can make changes

World system revolves around national governments International agencies generally lack "teeth" Coordination problems with individual action Rich countries have more power OECD Countries

The Economy Technology Complexity Corporations Politicians Public opinion Climate change deniers Structural limitations Capitalism? Representative democracy?

slide-32
SLIDE 32

The Economy The Economy

Mitigating climate change is expensive But more "expensive" to do nothing Maximum emissions reduction rate (3-5% p.a.) e.g. need to replace coal power plants before retiring them Short-term and "efficiency" focus of economics

Technology Technology

Things we already have low/zero carbon replacements for: Electricity generation Cars / Local transport Buildings

Technology Technology

Things we don't really have good low/zero carbon replacements for: Air Travel Shipping Meat (including fish) Plastic With some social changes, technology not really a barrier

slide-35
SLIDE 35

Complexity Complexity

Climate change is "Super Wicked": Time is running out The people causing the problem are involved in solving it No global authority to address it Easier to defer action

30

slide-36
SLIDE 36

Complexity Complexity

Climate change is a hard problem.... But, we're not really doing the "easy" things, e.g. Price on carbon National-level climate legislation (zero carbon bill) Ambitious Paris NDCs Planning for low-carbon future

31

slide-37
SLIDE 37

Corporations Corporations

Vested interests (esp. fossil fuel companies) Often have a lot of money and influence Spread disinformation, foster doubt But.... Highly reliant on consumer behaviour Also reliant on political influence

Politicians Politicians

Shouldn't they be doing more to lead us forward? Influence of money in politics Short-term focus Politicians want to get re-elected

Public opinion Public opinion

Public opinion can shape policy Politicians want to keep voters happy What do people think about climate change?

People who don't believe climate change is happening People who don't believe it is caused by humans People who don't think it's a serious problem

  • Approx. 10-20% of the population are deniers

70-80% concerned about climate change ...and want something done about it So shouldn't politicians be acting on this public concern?

Issue salience Issue salience

Most people are concerned about climate change But most people are more concerned about other issues Usually a small number of issues on the political agenda at one time Most people don't vote with climate issues in mind Not enough public pressure on politicians

Reforms probably needed Regulations/taxes needed "One economics, many recipes" Replacement? But with what? Would strong public engagement
