The biggest barrier to emissions reductions is increasingly our inability to quickly build clean energy: solar, geothermal, wind, nuclear, transmission, battery storage, etc. Projects are held back by a thicket of regulations and reviews.

"Coming to Scott’s Addition: Bike-ped paths and a little more green"

So much detail in this article regarding bike/ped infrastructure and greening efforts in @ScottsAddition (nice work @jer_science!).

A millennium-long record from Galápagos corals suggests that El Niño is intensifying as the planet warms, with ENSO variability in the eastern Pacific roughly 37% higher than during the preindustrial era.

The findings in Science suggest that climate change is already amplifying one of the world’s most important sources of extreme weather, with potentially growing risks to ecosystems, infrastructure, and human societies.

A recent viral graph found fewer days in the contiguous US above 95F/100F/105F today than in the 1930s.

But the graph is misleading – it fails to correct for changing measurement times and techniques, and overstates regional warmth. I take a deep dive at The Climate Brink.

🚨BREAKING🚨: new study shows that congestion pricing literally saves lives by improving emergency response times

On this hot fourth of July it is worth reminding folks that its not the sun that's causing global warming. Solar output (as measured by satellites) has been flat over the past 50 years when global temperatures have shot up.

Its our emissions of CO2 and other greenhouse gases.

In case you were wondering, there's no train service in the state of Wisconsin that is faster than it was 100 years ago.

Think about that for a minute.

birders and yimbys are the same movement and haven't been introduced. the thing wrecking bird habitat isn't the six-story apartment, it's the cul-de-sac that bulldozed forty acres of forest so eleven families could each keep a lawn that feeds no insects and therefore no birds

This Bellevue-Seattle listings comparison is an unbelievably vivid YIMBY map

In Seattle, people ask how legalizing all these $700k condos makes housing far more affordable

In Bellevue, those condos are illegal & instead they mandate $3M single family homes. There's the answer

“Air pollution fell substantially as Paris restricted car traffic and made way for parks, people-streets and bike-lanes.”

Better for the climate, better for health, better for livability and quality of life.

Common sense.

Such a no-brainer, it’s remarkable that more cities HAVEN’T done the same.

Building shade is as good if not better than tree shade for protecting people from extreme heat stress, especially in areas where big canopy trees are hard to maintain, so taller buildings and shade structures should be a bigger part of our strategy for urban heat resilience

What slightly-unhinged views on urbanism/cities do you hold dearly? Hobby horses and petty beefs?

[Annemarie Gray @annemariegray]

Excellent stuff by NYT Ed Board:“To bring down housing costs, cities and towns need to make two principal changes. First, they should loosen zoning laws to allow more multifamily homes. …Second, cities and towns should make it easier to build where it is already legal.”

There are 0 high-cost, high housing production cities in the US.

IZ (inclusionary zoning) is “vibes based planning”.

IZ is intended to benefit the politician proposing it at the expense of the lower income person needing it.

[Hayden @the_transit_guy]

Even in the arguably most car dependent metro in the country, there’s a clear demand for walkable spaces and dense urbanism. Stop making it legal to only build car dependent sprawl and then use that reality to say no one demands anything else.

@RigganRVA left turn hardening would help so much along the Franklin St bike lane

If it happens ones, it can be a coincidence.
If it happens twice, it starts to be a pattern.
If it happens 40 times, we have truth!

A @EUROCITIES survey across 38 European cities found: lower urban speed limits aren’t slowing cities down. They're just making them work better!

[Hayden @the_transit_guy]

A city that treated the housing crisis like a five-alarm fire made it legal to build so much housing that it actually reduced rent by a lot. Who would’ve guessed?
