Climate talks chief, who also heads oil company, says world must 'attack all emissions, everywhere'

The head of this year’s United Nations’ climate talks called Thursday for governments and businesses to tackle global warming by reducing greenhouse gas emissions in all regions and sectors if they want to stop the planet from passing a key temperature limit agreed on more than seven years ago. Sultan al-Jaber of the United Arab Emirates, who also heads one of the country’s state oil companies, told senior officials from Europe, Canada and China gathered in Brussels that record-breaking heat seen in parts of the world recently shows the need for urgent action to curb emissions.

Little-known but efficient, a different way to heat and cool your house

Summers are famously humid in New York State, but life in the Maioli household has gotten more comfortable since the couple installed a new heating and cooling system — one that isn’t well known yet in the U.S. “My wife is pretty happy because in the summer we can keep it to as cold as we like,” typically 69 or 70 F, said Joe Maioli, in Ontario, New York. In 2021, the couple installed a geothermal or ground source heat pump. The units you see that look like box fans outside homes and businesses are the more common air-source heat

Here's how geothermal energy heats and cools a home

Some homeowners looking to switch out their heating and cooling systems are turning to home geothermal — also known as ground source — heat pumps. It’s a technology that relies on a simple physical fact: Dig several feet below Earth’s surface, in the coldest winter or the hottest summer, and the temperature will be around 55 degrees. Geothermal takes advantage of that constant temperature by pushing water with some antifreeze through a loop of flexible pipe that runs deep underground. The water gets circulated by a heat pump system, usually located in the basement. When the house needs cooling —

In ‘Oppenheimer,’ Christopher Nolan builds a thrilling, serious blockbuster for adults

Christopher Nolan has never been one to take the easy or straightforward route while making a movie. He shoots on large-format film with large, cumbersome cameras to get the best possible cinematic image. He prefers practical effects over computer-generated ones and real locations over soundstages — even when that means recreating an atomic explosion in the harsh winds of the New Mexico desert in the middle of the night for “Oppenheimer,” out July 21. Though, despite internet rumors, they did not detonate an actual nuclear weapon. And as for the biography that inspired his newest film,

In 'Oppenheimer,' Cillian Murphy finally gets to lead a Christopher Nolan film

The day Christopher Nolan called Cillian Murphy about his new film, “Oppenheimer,” Murphy hung up the phone in disbelief. The Irish actor, though a regular presence in Nolan films going back almost two decades, had always been a supporting player. This time, Nolan wanted him to lead. “He’s so understated and self-deprecating and, in his very English manner, just said, ‘Listen, I’ve written this script, it’s about Oppenheimer. I’d like you to be my Oppenheimer,’” Murphy, 46, told The Associated Press earlier this year. “It was a great day.” For Murphy, it is never not exciting to get a call

Meteorologists say Earth sizzled to a global heat record in June and July has been getting hotter

An already warming Earth steamed to its hottest June on record, smashing the old global mark by nearly a quarter of a degree (0.13 degrees Celsius), with global oceans setting temperature records for the third straight month, the U.S. National Oceanic and Atmospheric Administration announced Thursday. June’s 61.79 degrees (16.55 degrees Celsius) global average was 1.89 degrees (1.05 degrees Celsius) above the 20th Century average, the first time globally a summer month was more than a degree Celsius hotter than normal, according to NOAA.

India is set to launch a lander and rover to explore the moon’s south pole

India was set to send a spacecraft to the far side of the moon Friday in a follow-up mission to its failed effort nearly four years ago to land a rover softly on the lunar surface. Chandrayaan-3, the word for “moon craft” in Sanskrit, will take off from a launch pad in Sriharikota in southern India with an orbiter, a lander and a rover. It will embark on a journey lasting slightly over a month before landing on the moon’s surface later in August. A successful landing would make India the fourth country — after the

China accuses US of militarizing space following protest over Navy plane's Taiwan Strait transit

Amid a freeze in military-to-military contacts, China is accusing the United States of militarizing outer space, a day after it protested the passage of a U.S. Navy P-8A Poseidon anti-submarine aircraft through the Taiwan Strait. Chinese Defense Ministry spokesperson Col. Tan Kefei said on Friday that U.S. actions, including the establishment of the Space Force in 2019 as the newest branch of the military, have “had a great negative impact on space security and global strategic stability.” “In recent years, the United States has accelerated the militarization of space,” Tan said. “I would like to reiterate here

Alaska volcano spews ash cloud high enough to draw weather service warning for pilots

An erupting volcano in Alaska’s Aleutian Islands sent a towering cloud of ash into the air Friday, prompting the National Weather Service to issue an inflight warning to pilots. The Shishaldin Volcano began erupting July 11, according to the Alaska Volcano Observatory. A U.S. Coast Guard overflight confirmed lava erupted the same day within the summit crater. A significant explosion at 1:09 a.m. Friday produced an ash cloud that reached up to 40,000 feet (12,192 meters) and drifted south over the Pacific Ocean. A second smaller explosion at 7:10 a.m. Friday reached about 15,000 feet (4,572

Unhealthy air quality lingers across parts of U.S. from drifting Canadian wildfire smoke

For Chicagoans planning a lengthy outdoor run Monday, “today is not necessarily the day for that,” according to Kim Biggs of the Illinois Environmental Protection Agency. Extensive swaths of the northern United States awoke to unhealthy air quality Monday morning or were experiencing it by midafternoon, according to the Environmental Protection Agency’s AirNow.gov Smoke and Fire map. Fine particle pollution caused by smoke from Canada’s wildfires is causing a red zone air quality index, meaning it is unhealthy for everyone.

Mammals may have hunted down dinosaurs for dinner, rare fossil suggests

An unusual find in China suggests some early mammals may have hunted dinosaur for dinner. The fossil shows a badgerlike creature chomping down on a small, beaked dinosaur, their skeletons intertwined. The find comes from a site known as “China’s Pompeii,” where mud and debris from long-ago volcanoes buried creatures in their tracks. “It does seem like this is a prehistoric hunt, captured in stone, like a freeze frame,” University of Edinburgh paleontologist Steve Brusatte, who was not involved with the study, said in an email.

Alaska volcano's week-long eruption spews another massive ash cloud

An ongoing eruption of a remote volcano in Alaska’s Aleutian Islands produced an ash cloud so large Tuesday warnings were sent to pilots about potentially dangerous conditions. The ash cloud with an initial height of around 5.5 miles (8.9 kilometers) was drifting south-southeast from Shishaldin Volcano, the Alaska Volcano Observatory said in a statement. The eruption was described as moderate with ashfall drifting toward the Pacific Ocean, creating a potential concern for air traffic or boats, said Matt Loewen, a research geologist with the U.S. Geological Survey at the observatory. The volcano is about 700 miles

Two planets sharing same orbit around their star? Astronomers find strongest evidence yet

Astronomers reported Wednesday the discovery of what could be two planets sharing the same orbit around their star. They said it’s the strongest evidence yet of this bizarre cosmic pairing, long suspected but never proven. Using a telescope in Chile, the Spanish-led team spotted a cloud of debris in the same orbit as an already confirmed planet circling this star, 370 light-years away in the constellation Centaurus. They suspect it’s either a planet in formation or remnants of a planet that once was. Asteroids are known to accompany planets around their star — for example,

Exclusion of race in federal climate justice screening tool could worsen disparities, analysis says

A screening tool the federal government is using to decide which neighborhoods have a disproportionate amount of pollution and risk of damage from climate change could worsen air pollution exposure disparities along racial lines, according to a new analysis. Researchers from several universities around the United States who modeled the potential effects of the use of the tool in guiding federal investment told The Associated Press it’s because race was excluded as a part of the equation that decides which communities are the most in need.
