Polls show that Democrats and Republicans in battleground states want to hear more from candidates about the climate crisis

Most Americans feel unease or alarm about the climate crisis and, in both red and blue states, want to know how political leaders are going to fix it. But in midterm election campaigns across the US, candidates have responded to this desire with near silence.

People in the US have this year endured a record hot summer as well as soaring costs, equating to roughly $2,000 per household, in extra energy and mortgage payments, due to the country’s dependence on a fossil fuel supply scrambled by Donald Trump’s decision to attack Iran.

Ana Reyes demands Trump officials explain East Potomac tree cutting saying it will probably cause ‘irreparable harm’

US district judge Ana Reyes on Monday ordered a 24-hour halt to tree cutting at the historic East Potomac golf course while she decides on an emergency order from plaintiffs concerned that Donald Trump’s plans for the course are moving forward despite a pending court case challenging them.

“Tree removal for routine maintenance is not exempt from this order,” Reyes wrote. “Plaintiffs are likely to suffer immediate and irreparable harm in the absence of preliminary relief.

Planting cover crops or perennial plants can protect soil amid potential flooding. Congress must act to protect these practices

As forecasters warn that this year’s El Niño could become the strongest on record, concerns are growing about its effect on agriculture and food security.

The United States will not be hit nearly as hard as Central and South America, the Caribbean and southern Africa, but severe weather could cause significant crop loss in some parts of the country.

Heat and humidity have led to one of the worst mosquito years in recent history, with West Nile virus at a decade high

Los Angeles might be best known for blue skies, beaches and film premiers — but for the last several years it’s held another, unenviable distinction: the most mosquito-infested city in America.

And this year has been especially nightmarish, thanks to a series of heatwaves and an extra-powerful El Niño. Locals have called it a summer of “living hell” as clouds of mosquitoes swarm backyards and leave diners at open air patios scratching their ankles.

Protesters spent months occupying an ancient cottonwood. Then a tense standoff with US border patrol came to a head

A 200-year-old cottonwood tree near the US-Mexico border, known as the “grandmother”, has been destroyed to make way for the construction of Donald Trump’s border wall, despite a months-long effort by protesters trying to save it.

In late July, land defenders began a tree-sit in the ghost town of Lochiel, Arizona, taking turns occupying a platform high in the tree’s canopy. The group remained there for more than 70 days.

Liability lawsuits have held tobacco, oil and pharma companies to account in the past. AI investors won’t ignore this threat

The most basic function of government is to protect people from harm. Two growing phenomena – the climate crisis and AI – pose escalating risks of extraordinary harm.

The climate crisis is already causing floods, wildfires, drought and record heat. AI agents are already escaping super-secure environments to hack into systems they’re supposed to avoid.

A mix of natural disasters could all befall the state at once as it finds itself in the crosshairs of the climate phenomenon

On a cloudless autumn afternoon, sunlight sparkled on the water that had quietly swallowed a busy intersection to the north of San Francisco, as the surrounding rush-hour traffic slowed to a painful crawl.

There were no crashing waves or storm surges to blame for the flood. Marin county was one of many areas up and down the California coast affected by high tides last week, as parts of the Pacific swelled with excess warmth.

John Murdock had been working for the agency for 18 years and his resignation comes during an exodus of longtime federal workers and scientists

An 18-year veteran of the US Department of the Interior has resigned in protest from the sprawling federal agency, denouncing “a deeply troubling assault on the rule of the law” that took place at the department under Donald Trump.

John Murdock, an attorney and self-described conservative Christian, began working for the agency’s legal office in 2002. In his resignation letter, first sent to his supervisor earlier this year and obtained exclusively by the Guardian and Public Domain, Murdock cites “glaring legal flaws” he witnessed within the agency during the course of the Trump administration, as well as concerns over offshore oil and gas drilling, the aggressive push to expand fossil fuels and the flouting of environmental regulation.

For-profit water corporations, federal cuts and climate crisis are ‘supercharging water rate hikes’, study co-author says

US households are paying 62% more for drinking water than they did a decade ago – outpacing inflation, grocery prices and household incomes, according to a new study.

Food & Water Watch, a Washington DC-based non-profit, analyzed 2025 billing data from the 500 largest community water systems in the US, which together serve about 155 million people, or 45% of the country’s population. The analysis compared current rates with data from a similar Food & Water Watch survey conducted in 2015. The study does not include wastewater or storm water charges, which are often billed separately from drinking water service.

An international symbol for the city, the sign is also hallmark of the region’s environmental richness

Atop Mount Lee, in the heart of Los Angeles, the wind is quiet. Two red-tailed hawks sail above, barely flapping as they coast the thermal air like surfers on a wave. Standing beside the giant letters of the Hollywood sign, the city seems peaceful. On a clear day, blocks and blocks of homes unfold beneath and the skies reveal sights all the way to Catalina Island – 10 miles out, across the Pacific.

That’s the beauty seen from the Hollywood sign.

Court starts new term hearing Suncor Energy and ExxonMobil’s attempt to stop lawsuits at state level

The US supreme court begins its new nine-month term hearing arguments Monday in a high-stakes case in which big oil companies are attempting to strike a fatal blow against lawsuits that seek to hold them accountable for the climate crisis.

In Suncor Energy versus the County Commissioners of Boulder County, local officials in Boulder are suing Suncor Energy and ExxonMobil in state court to force the companies to share a portion of the costs that climate change has imposed on local taxpayers. However, Exxon and Canada-based Suncor are arguing that federal law prevents state courts from hearing Boulder’s climate change lawsuit.

Temperatures in US state forecast to hit high 30s celsius this week, while regions in Indonesia grapple with wildfires

The National Weather Service in the US has issued extreme heat warnings for parts of southern California, including Los Angeles, until Thursday, as temperatures are expected to hit the high 30s celsius. Burbank, a suburb north of Los Angeles, recorded 39C on Saturday, a few degrees shy of the October record for the region set in 1987. A persistent area of high pressure will remain in place this week, leading to further hazardous hot weather and increased fire risk.

Parts of Indonesia are in the midst of an extreme wildfire season, which has peaked over the past month. Western Kalimantan (Borneo) and southern Sumatra have been particularly badly affected. The lack of rainfall has dried the usually water-logged tropical soils, meaning that fires have been able to spread quickly, above and below the surface. Indonesia’s soils are also extremely rich in peat, meaning that the smoke produced from the fires contain higher levels of toxic gases such as sulphur dioxide and carbon monoxide. Cities in surrounding areas and as far as Malaysia and Singapore have experienced reduced air quality in recent weeks as a result. Drought and wildfires are more common in this part of the world during El Niño events owing to suppressed thunderstorm activity.

A statewide initiative pairs climate-focused coursework with community service – and is spreading to other states

As a student at a high school not far from Denver’s main airport, Anthony Muñoz wondered whether the jet fuel from airplanes flying above his campus was harming living things.

An avid gardener, Muñoz partnered with a local university to create a garden on the campus of his charter school, Vista Academy, filling it with native plants that could detect ground-level ozone pollution. He also worked with climate scientists from the National Center for Atmospheric Research, a federal office in nearby Boulder, who directed Muñoz on what data to collect, what the condition of leaves reveals about air quality and why milkweed matters for monarch butterfly migration.
