Sinking U.S. cities more exposed to rising seas: study

Sea level rise could hit major U.S. cities like New Orleans and San Francisco harder than expected by mid-century because coastal land is sinking, researchers said Wednesday, warning current flood defences leave people and property at risk.

Global warming is melting ice sheets and glaciers and raising ocean water levels across the world, with predictions that the United States will see some of the fastest increases, threatening coastal regions that are home to some 30 percent of the country's population.

NOAA warns world's coral on verge of 'worst bleaching event in history of the planet'

Driven by sustained climate-fueled oceanic heating, the planet is on the brink of another mass coral bleaching event that marine biologists warn could kill large swaths of tropical reefs including significant areas of Australia's Great Barrier Reef.

Scientists are sounding the alarm following months of record ocean temperatures exacerbated by the planetary emergency and the El Niño climate pattern in the Pacific Ocean.

Losing their tails provided our ape ancestors with an evolutionary advantage

Put the word “evolution” into Google images and the results are largely variations on one theme: Ralph Zallinger’s illustration, March of Progress. Running left to right, we see a chimp-like knuckle walker gradually becoming taller and standing erect.

Implicit in such images – and the title of the picture – are biases in common views of evolution: that we are some sort of peak, the perfected product of the process. We imagine we are indeed the fittest survivors, the very best we can be. But seen that way, there’s a paradox. If we are so amazing, how come so many of us suffer from developmental or genetic diseases?

The ghosts of the past: Pop music is haunted by our anxieties about the future

In 2011, pop music scholar Simon Reynolds was already observing pop culture’s fascination with its own past, noting that “we live in a pop age gone loco for retro and crazy for commemoration.”

For Reynolds, this obsession with the past has the potential to bring about the end of pop music culture: “Could it be,” he asks, “that the greatest danger to the future of our music culture is … its past?”

Scientists develop mathematical model to optimise elite athletes' performance

Scientists have developed a mathematical model that promises to optimise training for competitors in 400-meter and 1,500-meter athletics events, according to a study published Tuesday.

The model is based on performance data gathered from elite athletes including Olympic 1,500 meters champion Jakob Ingebrigtsen of Norway, Dutch world indoor 400m world record holder Femke Bol and Britain's Matthew Hudson-Smith at the 2022 European Championships in Munich.

California man first in U.S. charged with smuggling greenhouse gases

WASHINGTON — A California man has become the first person in the United States charged with illegally smuggling greenhouse gases into the country, officials said Monday.

Michael Hart of San Diego was arrested under the American Innovation and Manufacturing Act of 2020, which prohibits the importation of hydrofluorocarbons (HFCs) without proper permits from the Environmental Protection Agency (EPA).

Cities are vulnerable to heatwaves. But green spaces can help more than we thought

It’s not just that the planet is getting hotter; cities are getting much hotter than their surroundings. In fact, urban heatwaves have become a common occurrence, affecting 1.7 billion people. In Europe alone, the 2023 heatwave killed over 61,000 people. Now, a new study by researchers in the U.K. shows how much green interventions can help cool down cities. The world is heating up as a result of our activity — by now, hopefully, we all know that. But fewer people know that cities are heat islands. The Urban Heat Island is a phenomenon where urban and suburban areas experien...
