After San Diego Installed a Protected Bike Lane, Ridership More Than Doubled โ€” and Hasnโ€™t Stopped Growing. โ€œWhen people feel safe, they ride.โ€

Huge bike growth in San Diego after making it safer to ride!

Annual bike trips jumped 50k to 115k after the lane was installed in 2021. By 2025, 132k.

โ€œThe lesson is straightforward: when people feel safe, they ride.โ€

Federal Judge Rules Trump Can't Kill Congestion Pricing - Streetsblog New York City Trump does not have the power to toss out the Biden administration's decision to authorize the tolls, Judge Lewis Liman ruled.

Federal Judge Upholds NYC's Congestion Pricing that has:
-reduced traffic
-made buses faster and more reliable
-helped businesses
-reduced pollution
Time for other cities to replicate this successful policy!

E.P.A. Weakens Limits on Mercury From Coal Plants

We cannot ditch coal fast enough. Beyond the climate damage, itโ€™s poisoning us.

โ€œThe EPA on Friday weakened pollution limits for coal-burning power plants, allowing them to release more heavy metals including mercury, a powerful neurotoxin linked to brain damage.โ€

Oregon mandates heat pumps in new housing The update to the stateโ€™s residential energy code could save residents of housing built after the change an average of $125 a month in energy costs, an analysis found.

We need stronger protections against manufactured opposition. Submitting a comment in a regulatory proceeding in someoneโ€™s name without their knowledge or consent needs to have real consequences.

Southern California air board rejected pollution rules after AI-generated flood of comments SoCalโ€™s pollution authority scrapped a plan to phase out gas-powered appliances after receiving more than 20,000 emails sent by an AI-powered platform called CiviClick.

Fossil fuel industryโ€™s latest tactic: flood regulators with AI generated comments. In California, 20k+ fake AI emails helped kill @southcoastaqmd.bsky.social clean air rules. People actually want heat pumps, their efficiency, and cleaner/healthier indoor air. www.latimes.com/environment/...

Local and state governments are key to US climate policy and will keep moving forward. At @runonclimate.bsky.social, weโ€™re advancing climate policy in partnership with city and county governments across the country.

Weโ€™ve come to take for granted what Trump is doing on climate and energyโ€ฆ

Agent tampers with evidence and brags about shooting this woman and his colleagues love it.

Weโ€™re fortunate that Marimar Martinez wasnโ€™t killed like Good and Pretti.

Another instance of DHS lying about what happened and smearing a preschool teacher as a domestic terrorist.

Ein vollkommen passender Vergleich. Natรผrlich ist nicht alles dasselbe aber in beiden Fรคllen:
-weit verbreitete, terrorisierende Gewalt
-Unterdrรผckung und Deportation von ethnischen Minderheiten mit dem Ziel, ihre Zahl im Land zu reduzieren
-Truppen neulich von einer autoritรคren Regierung errichtet

Why a New Mexico Developer Quit Natural Gas

Why are developers choosing to build all-electric homes? Theyโ€™re faster and cheaper to construct than dual-fuel homes, and heat pumps are more efficient.
Also, fewer emissions and less indoor air pollution! @buildingdecarb.org @carabuckley.bsky.social

I helped to establish DHS in 2002 and 2003 and later had the homeland security portfolio as a White House Counsel and served as General Counsel of the Department.

I am enraged and embarrassed by DHSโ€™s lawlessness, fascism, and cruelty.

Impeach and remove Trumpโ€”now.

The deadly shooting in Minneapolis today was a straight-up execution of a protester by Trump's federal brownshirts. 

The thugs wrestled him to the ground.  They pistol-whipped him, then shot him multiple times.  They murdered him.

Beyond helping establish DHS itself in 2003, Mr. Mitnick was a senate-confirmed Trump choice for General Counsel for DHS in his first term. I've talked with him a few times, and he's not a man for hyperbole. So bear that in mind when you see him calling out DHS's "lawlessness, fascism, and cruelty."

Efficient electric equipment, powered by clean sources, is the answer to the energy affordability crunch - CommonWealth Beacon Better equipment and cheaper energy sources are critical to achieving an affordable energy future.

Efficient electric systems bring down costs!
Efficient:
-lower power use, same outcome
-less infrastructure needed for growth
All-electric:
-build/maintain one distribution system instead of two
-more overall power consumption >> lower fixed costs per MWh

Top EU court mandates same-sex marriage recognition across borders The Luxembourg-based court said a decision by Polish authorities infringed on a same-sex coupleโ€™s freedom of movement.

The EUโ€™s top court ruled today that when a same-sex couple is legally married in one member country, any other member country where they move or reside must recognize that marriage.
