Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging. At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.

The angry rumble of a speeding SUV. The metallic smog of backlogged traffic. The aching heat of sun-dried neighbourhoods baking in an oven of concrete and asphalt. For most people, the mundane threats that plague our environments are likely to annoy more than they spark dread. But for scientists who know just how dangerous our surroundings can be, the burden of knowledge weighs heavy each day.

A 400-mile blanket of fog has socked in California's Central Valley for weeks. Scientists and meteorologists say the conditions for such persistent cloud cover are ripe: an early wet season, cold temperatures and a stable, unmoving high pressure system. But take a stroll through X, Instagram or TikTok, and you'll see not everyone is so sanguine. People are reporting that the fog has a strange consistency and that it's nefariously littered with black and white particles that don't seem normal.

New details emerged this week about the massive February fire that erupted at the Martinez Refinery Company and released more than 7,000 gallons of hydrocarbon materials into the air, as officials revealed that oil crews had been using incompatible radio systems that prevented immediate contact with local public safety agencies. While county firefighters arrived on the scene 14 minutes after being notified of a fire at MRC, crews were stalled outside, unable to contact the refinery operators on site - a communication gap that delayed the establishment of a unified command center by nearly two hours.

The agency previously estimated that the higher standards set in 2024 would collectively save Americans $23 billion in fuel costs over the years, or about $600 for each passenger car and light truck owner over the lifetime of their vehicle. The rules were expected to cut down gasoline use by 70 billion gallons through 2050. That would avoid 710 million metric tons of planet-heating carbon dioxide pollution, equivalent to taking more than 165.6 million gas-guzzling passenger vehicles off the road for a year.

Air pollution has reached "alarming" levels in the Iranian capital, Tehran, leading authorities to close schools and universities and ban truck travel in the region in the latest environmental crisis to strike the Middle East nation. The Air Quality Index in Tehran and surrounding cities on November 29 climbed to between 170 and 200 -- considered to be "unhealthy" for all age groups, Iranian media reported.

Each day, Kiran Kasbe drives a rickshaw taxi through his home neighbourhood of Mahul on Mumbai's eastern seafront, down streets lined with stalls selling tomatoes, bottle gourds and auberginesand, frequently, through thick smog. Earlier this year, doctors found three tumours in his 54-year-old mother's brain. It's not clear exactly what caused her cancer. But people who live near coal plants are much more likely to develop the illness, studies show, and the residents of Mahul live a few hundred metres down the road from one.

Nearly 59,000 Iranians die prematurely due to air pollution in year to March, according to officials. Tehran, Iran Iranians in the capital and many other cities across the country are breathing in toxic fumes as authorities resort to burning dirty fuel to produce electricity and cope with multiple ongoing crises. At 14 power plants, authorities for years have burned mazut, a dark residue of petroleum high in sulphur and other impurities, whenever they run out of natural gas to feed the electricity generators.

Or at least that's what's supposed to happen, as the end result is not really what was suggested in the early concept image sent to other publications. The impression would be of a simmering, partially translucent screen that would be lit from behind. To show off the church through a veil. In fact, it's a painted fabric hung over scaffolding and lit from the outside by a handful of spotlights at the bottom.

Every day. Nearly. Every. Damn. Day. Maybe twice a day. Shooting rigidly awake from blissful sleep into the literal warzone of bleating death engines. My complex is surrounded sometimes by several dudes just running their nozzles over the same already clean patch of grass. It sends my dog into a mania. It sends me into a depression. Running a commercial gas-powered leaf blower for one hour

Only one prosecution for illegal wood burning has been made in the past year despite 15,195 complaints across England, data shows. Additionally, just 24 fines were issued by local authorities between September 2024 and August 2025, responses to freedom of information requests by the campaign group Mums for Lungs revealed. In smoke control areas alone, 9,274 complaints were made a 65% increase on the previous year.

For most New Yorkers, convenience is all we see when we shop online. Click, buy, delivered. But what feels so easy to us is hurting our neighborhoods and the workers in Amazon vests who make it happen. The culprit? Last mile delivery centers, the giant hubs where companies like Amazon sort packages and send them to your doorstep. More and more of these have been popping up in New York.

According to a September 2025 report issued by Comité Cívico del Valle and Earthworks, Controlled Thermal Resources' proposed lithium mining operation, the Hell's Kitchen Lithium and Power Project, will have significant environmental impacts on the surrounding area. The operation, which is still in the beginning stages, will divert at least 6,500 acre-feet of fresh water each year, straining natural resources in an arid region that's already struggling to combat drought.

Residents of Zurich decided Sunday to severely restrict the use of leaf blowers and leaf vacuums. More than 61% of voters supported the restrictive rules, which authorities said would limit noise and dust pollution. Gas-powered leaf blowers and leaf vacuums will be fully banned in Zurich, Switzerland's most populous city. Only electric devices will be used to blow away dirt and debris.

Experiments show that the bacterial component of fine particulate matter has a highly potent inflammatory effect.

As the river flows through Baja California, it takes in untreated sewage and industrial waste from Tijuana, then crosses the U.S.-Mexico border into San Diego County, where beaches are regularly closed because the surf is filled with bacteria from the river. Researchers have now gained new insights into how that water pollution is creating air pollution that besets nearby communities.
