If we care about the world, we should:
  • be very concerned about climate change:
    • mankind has changed the climate
    • the scale of harm being done makes continued burning of fossil fuels morally indefensible
    • action on climate change has not gone according to plan
    • governments have not acted in line with their commitments to urgent action
    • the global total of CO2 emissions has continued to rise
    • the rise in global temperature is now approaching the 1.5°C limit
    • the climate is deteriorating
    • there is much concern about catastrophic errors in decision making
  • aim to understand:
    • the science of climate change
    • the urgency of action on climate change - the rapidly dwindling carbon budgets
    • what should have happened: agreement of a plan to reduce emissions in line with the climate science and commitments given in the Paris and other agreements - and compliance with that plan
    • what has gone wrong, why policy making has been so poor:
      • understating the urgency of action, and advocating of inadequate policies - i.e. climate urgency denial
      • failures across society: by government scientists, politicians, the media, climate advocacy groups, sceptics, businesses, the legal system, other organisations, and individuals
      • fragmentation of climate advocacy leading to chaotic and inconsistent policy proposals
    • what options do we have now: implement organised radical change, or have disorganised radical change forced upon us by a deteriorating climate
  • take action:
    • improve decision making:
      • take steps to avoid optimism bias, overconfidence, groupthink, and denial
      • apply scientific rigour to the policy making process
      • stop advocates of climate action contradicting the IPCC and each other
    • rational collective action across society: urgent radical reduction in emissions across all sectors, a rapidly increasing carbon tax
    • disseminate accurate information
    • take personal action
    • challenge what is out of line with the science.

This web page is a summary of the science on climate policy making, written for people who feel that big decisions should be taken on the basis of facts and fairness.
The aim is to give the full truth, and nothing but the truth, even if it is not what is being generally discussed and not what people would like to hear.

Why we should be very concerned about climate change

Mankind has changed the climate
  • the effects are cumulative and mostly irreversible
  • the scale of harm being done by climate change is horrific:
    • one climate-related death for every 4000 tonnes CO2 emitted - e.g. each year's CO2 emissions from the UK will result in around 150,000 climate deaths
    • climate refugees

    • loss of biodiversity.
This makes continued burning of fossil fuels morally indefensible.

Action on climate change is very urgent but has not gone according to plan:
  • in the
    Paris Agreement,[122]
    countries made commitments to limit global warming to well under 2°C (usually taken to mean 1.7°C), and to pursue efforts to limit it to 1.5°C
  • this means phasing out fossil fuels
  • the scientific advice was that these commitments require
    "rapid and far-reaching transitions"[31]
    throughout society
  • but governments have not acted in line with the promises given - actions are completely at variance with the speed of change needed

The climate has continued to deteriorate
  • total global CO2 emissions are still rising
  • in developed countries, emissions are not falling fast enough
  • the global temperature rise (longer term average) was around 1.3°C in 2024 - and at its current rate will reach 1.5°C in 2030, and 1.7°C in 2036.

Governments cannot be trusted on important questions
  • they have a poor record of decision making
  • in the UK, there is a recurring pattern of wasting billions of pounds on ineffective policies and ignoring effective policies

There is much concern about catastrophic errors in decision making
  • the UN Secretary-General has warned: "Some government and business leaders are saying one thing - but doing another. Simply put, they are lying."
  • despite the global temperature rise being likely to reach the Paris agreed limit of 1.5°C in 2030, governments continue to talk about Net Zero 2050 as if this is an acceptable timescale
  • climate protesters who are very aware of the situation are very vocal and not deterred by long prison sentences.

The essential points

The science of climate change
  • the steady rise in global temperature as mankind dumps more CO2 into the atmosphere
  • the unacceptable level of climate deaths, climate refugees, biodiversity loss and sea level rise

The urgency of action on climate change
UK carbon budget chart net zero 2050
  • the global
    carbon budget
    for 1.5°C runs out in 2030, and even sooner in developed countries, e.g. the UK's fair carbon budget for a 50% chance of limiting global warming to 1.5°C runs out in 2027 - see chart and document 177
  • this means radical changes in lifestyles for many until renewable alternatives are developed, if temperature targets are to be met

What should have been done by governments and wider society
  • discussion of the implications of the Paris Agreement, agreement of a plan to eliminate fossil fuels, and implementation of the plan

What has actually been done
  • there have been many declarations of a climate emergency, but planning has been of non-emergency policies, and there has been little action

What has gone wrong
It is essential to understand what has gone wrong, why policy making has been so poor, so that effective action can be planned:
  • there has been no general discussion of the imminent exhaustion of a fair carbon budget - 2027 in the UK for compliance with the 1.5°C commitment
  • instead, the urgency of action has been understated - inadequate government timescales (such as Net Zero 2050) dominate discussions and have not been challenged - with inadequate policies being advocated and planned
  • this is a general failure across society: by government scientists, politicians, the media, climate advocacy groups, sceptics of climate action, businesses, the legal system, other organisations, and individuals
  • the evidence is that it is not a sporadic problem, and it is not a conspiracy of oil companies or billionnaires - instead there is a widespread failure of decision making - see document 189: Climate inaction and delay: Conspiracy or cockup?
  • even climate campaigners have understated the size and urgency of changes needed, fragmentation of climate advocacy efforts, leading to chaotic, inconsistent and inadequate policy proposals
  • flawed campaigning seems to be not just misunderstanding but a form of
    climate denial
    , which can be termed climate urgency denial.

What choices do we have now
  • our current lifestyles are unsustainable, so radical change is coming - we can choose to organise radical change, or have disorganised radical change forced upon us
  • whether to continue with inadequate non-emergency policies or treat climate change as the highest priority i.e. as an
    emergency
  • whether to continue with the target of limiting global warming to 1.5°C or to accept the system has failed and consider a higher limit of e.g. 1.6°C

Action needed

Correct the flawed decision making, in advocacy groups and in decision makers in government and across society
There is much talk of evidence-based policy making, as if that is adequate, but it is easy for decision makers to find some piece of evidence that fits with their preferred course of action and ignore the rest.
Instead we need the application of the full rigour of science to the policy making process - which will be referred to here as science-based policy making. This means
  • honesty and transparency
  • pooling of evidence, and agreeing a fair summary of it
  • acceptance that there is a risk that decision making is flawed - due to optimism bias, overconfidence bias, groupthink, denial, etc - and that measures are needed to overcome these biases
  • aiming for a consensus of reasonable people by
    • checking for consistency with others
    • working with others to resolve any inconsistencies
    • challenging anything inconsistent or misleading
  • resulting in a reasoned explanation of any decision, with enough detail included or referenced to ensure that any reasonable person would come to the same conclusion (reproducibility)
  • with procedures to scrutinise decisions and remove errors
  • shared decision making (SDM) so that all parts of society are involved


Decide on the speed of change
  • emergency (not routine) action
  • e.g. a pathway to Net Zero 2030

Advocate rational collective action across society
  • reduce fossil fuel use very rapidly, including a massive programme of insulation, ending leisure aviation, much reduced vehicle mileage, and restructuring of the food supply.
  • a rapidly increasing carbon tax.

Disseminate accurate information
  • explain that current affluent lifestyles are unsustainable,and will end one way or another
  • explain the promises made in the Paris Agreement and the choices we have

Take personal action
  • be part of the solution rather than part of the problem
  • reduce fossil fuel use as fast as possible

Challenge what is out of line with the science
  • stop advocates of climate action contradicting the IPCC and each other, e.g. Friends of the Earth's endorsing of the UK Government's Net Zero 2050 timescale
  • challenge misinformation - whatever the source
  • challenge inadequate government action.
