The seasonal news that #WhatsApp will stop working on #iPhone 5 and below #Android 4.3 highlights how the lack of Web apps is a significant environmental problem. Phones become obsolete in part because they don’t get OS updates, and they become incompatible with compiled apps. A lightweight OS for old phones would be more feasible if it mainly had to have a solid Web browser that facilitated a proper selection of #ProgressiveWebApps (& if manufacturers made open drivers/docs). #PWA #PWAs

Have you seen this one before? A short history of traffic engineering, via #copenhagenize. Manufactured car dependency takes a lot of forms, including how easy or hard we make it to get from A to B using different modes/methods. This is about vision, space prioritization, design, budgeting, operations/maintenance, etc. A deliberate result of skewed priorities.

Please boost to help save the Arctic. We’ve learned a lot about permafrost (frozen ground) and its role in global climate over the past decade. Unfortunately there are some false narratives being driven by the media. Here are some facts driven by our best science. 1) Permafrost underlies 1/4 of N hemisphere land and >1/2 of Canada. This makes 🇨🇦 more of a permafrost nation than a hockey nation. Frozen ground is literally a backbone for ecosystems and infrastructure. 1/

Proposal to stop referring to covid in the past tense and climate change in the future tense.

Reducing traffic speed from 50 to 30 km/h in cities is now implemented in the Netherlands. The big issue here is that road design should be in line with the allowed speeds. This means that you can’t have separated bike lanes om 30km/h roads. Many of the 50km/h roads are too congested to allow mingling between cyclists and automobiles. To overcome this paradox Leiden implemented these traffic lights. They turn red when drivers exceed the 30km speed limit. Resulting in an almost serene atmosphere.
