A Climate for Change?

Peter Stonham

ANOTHER REPORT from the experts, another apparent shrug of the shoulders from most of those who might usefully really take its worrying message on board. The UN’s Intergovernmental Panel on Climate Change (IPCC) has now published its latest guidance on what the world must do to avoid an extremely dangerous future. 

So, what’s the problem in not acknowledging the import of the massive 3675 page piece of work entitled Sixth Assessment report, Climate Change 2022: Impacts, Adaptation & Vulnerability. Too long to read? Well at least there also is a 37-page summary for policymakers, with information on the impacts of climate change on nature and human activity.

Perhaps a simple three-word message, like “we’re all doomed’ as Dad’s Army’s Private Frazer might have put it, would have better got the message across? Or the four words “ It’s now or never” as used by Imperial College London’s Professor Jim Skea, co-chair of IPCC Working Group III, the group of 278 authors responsible for the report.

At least the head of the UN, ultimate stewards of the report, didn’t mince his words either.

“Some government and business leaders are saying one thing - but doing another. Simply put, they are lying. And the results will be catastrophic,” said UN Secretary General Antonio Guterres.

Even if all the policies to cut carbon that governments had put in place by the end of 2020 were fully implemented, the world will still warm by 3.2˚C this century says the report.

That sort of temperature rise would see our planet hit by “unprecedented heatwaves, terrifying storms, and widespread water shortages”.

To avoid that fate, the world must keep the rise in temperatures at or under 1.5˚C this century.

The scientists have at least unveiled a plan that they believe can limit the root causes of dangerous climate change.

Even if all the policies to cut carbon that governments had put in place by the end of 2020 were fully implemented, the world will still warm by 3.2˚C this century says the report.

They say that there must be “rapid, deep and immediate” cuts in carbon dioxide (CO2) emissions. Currently rising Global emissions of CO2 would need to peak within three years to stave off the worst impacts.

But that means massive changes to energy production, industry, our consumption patterns and the way we treat nature. And our transport activity is in the front line to have to change. Its carbon emissions must peak by 2025, and fall rapidly after that, reaching net-zero by the middle of this century.

“I think the report tells us that we’ve reached the now-or-never point of limiting warming to 1.5C,” said IPCC lead author Heleen De Coninck, Professor of Socio-Technical Innovation and Climate Change at Eindhoven University of Technology.

The next few years are critical, say the researchers, because if emissions aren’t significantly curbed by 2030, it will make it nigh on impossible to limit warming later this century.

For transport, in practice, this means governments doing more to encourage walking and cycling instead of car travel, getting people to fly less, and putting in place the infrastructure for far more electric vehicles. For individuals, it means accepting the implications of all this.

The report suggests that increasing urbanisation could help drive adoption of mitigation strategies such as reduced car use, and renewable energy.

Keeping temperatures down will still require new technology to remove CO2 from the atmosphere, though some participants in the IPCC process are highly sceptical that such approaches will work.

“The idea of quick emissions reductions and large negative emissions technologies are a concern,” said Prof Arthur Petersen, from UCL, who was an observer in the approval session.

“There are a lot of pipe dreams in this report.”

It’s not that there hasn’t been plenty of brainpower and evidence brought together in its preparation, and of the others in the series of six IPCC reports which assess scientific, technical, and socio- economic information concerning climate change.

A total of 234 scientists from 66 countries have contributed to the three working group reports built on more than 14,000 scientific papers to produce the massive tomes of data and analysis. The final synthesis report is due to be finished by late 2022.

So, what’s missing from the discussion that could mean a clearer, faster practical response from both governments and citizens?

As our regular contributor John Dales explains in this issue of LTT it seems to be a fundamental feature of the human brain that it puts the immediate ahead of the future and looks for the distraction of the simplistic over the complex. We also know, to our cost, that only manifest crisis brings real change. Ask Ukraine.

Put brutally, it seems to most people and their leaders, the Climate Crisis hasn’t quite arrived yet.

Transforming British Transport: a genuine opportunity?
WHAT WAS Government thinking when it produced the Network North policy document? Was it thinking at all, beyond creating a cover position for the HS2 cancellation?
They helped build a new approach to local transport. Who will take the baton now?
THE HEAVENLY hall of fame for the heroes of transport planning has just admitted three of its most illustrious members. The loss of these important contributors in the field has also reminded us of some key steps in the emergence of this distinct area of professional endeavour. We are referring to David Bayliss, John Prescott and Dave Wetzel, whose obituaries appear in this issue.
Peak Car might be coming but some car-dependents look incurable
THE LAST FEW YEARS have seen considerable discussion about the possibility that long-established trends in car ownership and use are changing, and that we may even have reached the point of ‘Peak Car’ - at least in developed economies like the UK. Might the latest figures on both car sales and car ownership be significant in that regard? The Society of Motor Manufacturers and Traders (SMMT), the industry body that collates facts and stats on vehicle usage, revealed that UK car ownership fell by 0.2% to 35,023,652 in 2021, after a similar drop in 2020 - the first successive annual drops in ownership in more than a century.

Is all our travelling just a basic human need - or are some of us simply justifying unrealistic expectations?
Movement is inherent to life, and travel is often regarded as a basic human right. But does this apply to all travel, at all times, by everyone? Can we prove scientifically that travel is an essential characteristic defining humanity? And what follows in a world where it is so unevenly available, and can be damaging as well as enlightening? Phil Goodwin examines the subject with a critical eye.
Time for Total Transport to come out of the DfT’s ‘too difficult’ tray
NEW APPROACHES to how transport is most effectively planned and delivered tend to be more usually developed in modal, technological, operational or geographical silos, rather than all-embracing new paradigms. Changes generally emerge from disruptive new players, particular entrepreneurs breaking new ground and taking risks, technological revolutions, or challenging local political leaders prepared to stick their necks out. These are rarely characteristics to be found in centralised bodies or public authorities — least of all government departments.
The Urban SUVs: Too big for their boots, dangerous to others – and not paying their fair share either
A growing number of cars in urban areas are simply not right for the places they move around and park in, says John Dales. Whether it is space-take, road danger, emissions or congestion, large cars like SUVs are even more of a problem than conventionally-sized cars, and they are not paying appropriate charges for the trouble they cause. It’s something on which action is needed, and which some authorities are, encouragingly, starting to tackle.
