Significant change to transport will be essential if the worst impacts of climate change are not to become irreversible, the Intergovernmental Panel of Climate Change (IPCC) has warned.
Measures must be introduced now to create more connected and less car-dependent cities, encouraging homeworking and active travel and accelerating the shift to electric vehicles, it says.
Imperial College London’s Professor Jim Skea is co-chair of Working Group III, the group of 278 authors responsible for the report. “It’s now or never, if we want to limit global warming to 1.5°C,” he said. “Without immediate and deep emissions reductions across all sectors, it will be impossible.”

How more lanes and more money equals more congestion
In an expensive effort to curb congestion in urban regions, we have overwhelmingly prioritised one strategy: we have spent decades and hundreds of billions of dollars widening and building new highways. We added 30,511 new freeway lane-miles of road in the largest 100 urbanised areas between 1993 and 2017, an increase of 42%.

The myth of the American love affair with cars – washingtonpost.com
Emily Badger
This “love affair” was coined, in fact, during a 1961 episode of a weekly hour-long television program called the DuPont Show of the Week (sponsored, incidentally, by DuPont, which owned a 23 percent stake in General Motors at the time). The program, titled “Merrily We Roll Along,” was promoted by DuPont as “the story of America’s love affair with the automobile.”
Up to 40 vehicles set on fire in spate of arson attacks – wiltshirelive.co.uk
About 40 vehicles were deliberately set on fire – including about 20 at a Rolls Royce facility. Residents near the plant in Filton, South Gloucestershire, reported they were awoken by loud bangs and could see a huge fire.
On top of that about 20 vehicles were set alight in the Bristol area in the early hours of Sunday morning. Avon and Somerset Police first received a call at about 1.30am about a vehicle on fire in New Road, Stoke Gifford.
Every City’s Cycleway Network Should Be As Dense As Road Network, Says American Academic – forbes.com
Carlton Reid
“People on bicycles want to reach all destinations in a city just the same way that people in cars want to be able to reach all parts of the city,” says American academic Marcel Moran.
“A city’s bike network should be equivalent to the road network,” he told me via a Zoom call.
“The challenge is not where bike lanes should go, but where shouldn’t they go? And there are very few places we shouldn’t have safe bike infrastructure.”

Protesters continue to block UK oil terminals despite more than 100 arrests | Environmental activism | The Guardian
Clea Skopeliti
More than 100 people have been arrested as climate change protesters continued to block UK oil terminals as part of a campaign to disrupt the fossil fuel industry.
Supporters of Just Stop Oil began the action in the early hours of Friday morning at refineries near London, Birmingham and Southampton by climbing on to tankers and gluing themselves to roads.
The activists continued to disrupt oil terminals on Saturday morning and said they had gained access to further sites.
Essex police said officers arrested a total of 83 people after protests in the Thurrock district.
The force said 63 were arrested on Friday following protests in Oliver Road, Grays, London Road, Purfleet, and Askew Farm Lane, Grays. Another 20 people were arrested on Saturday in Oliver Road and Stoneness Road, Grays.

Talks stretch past deadline as governments are accused of trying to water down findings
Fiona Harvey
The world must abandon fossil fuels as a matter of urgency, rather than entrusting the future climate to untried “techno-fixes” such as sucking carbon out of the air, scientists and campaigners have urged, as governments wrangled over last-minute changes to a landmark scientific report.
What happens to the soil under heavily concreted environments? | Soil | The Guardian
Readers reply: what happens to the soil under heavily concreted environments?
What most people think of as soil exists only near the ground surface and has terrible engineering properties: whatever gets built on top settles unevenly and rain ingress can lead to swelling and erosion. So all the organic stuff containing the worms and dead leaves tends to be excavated, leaving firmer soil below to build structures on. Sadly, removing all that soil organic matter is taking quite a toll ecologically and environmentally (globally, soil is our No 2 carbon sink, after the oceans) so we need to be doing more to ensure we always return the nutrients to the earth. Ted O’Hare
If you look at the challenges faced by urban street trees, that’s probably an indication of the soil quality under heavily concreted areas. City trees grow in soil that is very depleted in nutrients due to a lack of top soil and organic matter from fallen leaves and other plant and animal debris; the soil will be much more compacted and less aerated, and surrounding surfaces are largely impermeable to oxygen and rainwater, which is also likely to be more polluted. Urban areas also act as heat islands increasing moisture evaporation. Consequently urban trees have a much shorter lifespan than suburban or rural trees, reflected by the soil quality. Mrs Lessing
