The higher the resolution, the more precise the forecasts: climate models. Credit: ETH Zurich More Climate models are a success story, given that much of what they predicted has actually come true. Nevertheless, Reto Knutti points out in a blog post, researchers still need new models. In 1950, meteorologists Jule Charney and Ragnar Fjørtoft joined

A vibrant pinkish-coloured seaweed that grows in temperate tropical waters could end up being a huge aid in reducing greenhouse gases, if scientists in Australia have their way. Researchers are currently looking into ways to sustainably mass-produce the crimson-hued algae – called Asparagopsis taxiformis – after a study five years ago demonstrated it almost completely

Bowing to pressure from environmentally conscious consumers, big brand shops have begun taking steps to strip their shelves of plastic wrapping More British supermarkets are starting to go “nude”. Bowing to pressure from environmentally conscious consumers, big brand shops have begun taking steps to strip their shelves of plastic wrapping over concerns about saving the

Long term exposure to pollutants from vehicle exhaust is linked to a heightened risk of the common eye condition age-related macular degeneration, or AMD for short, suggests research published online in the Journal of Investigative Medicine. Exposure to the highest levels of air pollutants was associated with an almost doubling in risk among those aged

A new technique for measuring oxygen levels in ancient rocks shows that oxygen levels in North American rocks leapt by nearly a third in just

Tiny algae called coccolithophores, such as this Discosphaera tubifera, play a major role in the global carbon cycle. New research shows that coccolithophores are mysteriously scarce in one of the most fertile and productive regions of the Atlantic Ocean.

Scientists in the US have flown directly through an exceedingly rare atmospheric phenomenon known as a ‘fire cloud’ – and they captured the unique, “otherworldly” moment on camera. Researchers with NASA and the NOAA were investigating smoke produced by the Williams Flats wildfire in Washington when they seized the opportunity to fly inside the rare

Researchers are increasingly studying the effects of environmental insults on psychiatric and neurological conditions, motivated by emerging evidence from environmental events like the record-breaking smog that choked New Delhi two years ago. The results of a new study publishing August 20 in the open-access journal PLOS Biology by an international group of researchers using large

Credit: Robert Lucian Crusitu/Shutterstock More Almost all scientists agree that burning fossil fuels is contributing to climate change. But agreement is less clear cut on how exactly it’s influencing rising global temperatures. The world is now 1°C warmer than it was in pre-industrial times. Is this solely down to emissions of greenhouse gases such as

Death came swiftly for Aldo Machado’s honey bees. Less than 48 hours after the first Apis mellifera showed signs of sickness, tens of thousands lay dead, their bodies piled in mounds. “As soon as the healthy bees began clearing the dying bees out of the hives, they became contaminated,” said Machado, vice president of Brazil’s Rio

Researchers led by Princeton University examined a range of possible climate-related impacts on the ocean to predict when these impacts are likely to occur. Some impacts – such as sea temperature rise and acidification – have already begun while others, like changes to microbial productivity, which serves as the basis of the marine food web,

The river bed of the Rhine is dried on August 8, 2018 in Duesseldorf, western Germany during an exceptionally long heatwave More Northern hemisphere summers will deliver dangerously longer heatwaves, droughts and bouts of rain even if humanity manages to cap global warming at two degrees Celsius, scientists said Monday. With one degree of warming

They have published their findings in the

Plastic pollution has reached the Antarctic wilderness. It’s at Earth’s highest peak, and its deepest chasm. And yet, the extent of this insidious plague can still take us by surprise. According to new research, plastic has now turned up camouflaged as ordinary pebbles. These small chunks of plastic – called pyroplastics – are created when

Credit: CC0 Public Domain Prevailing economic research anticipates the burden of climate change falling on hot or poor nations. Some predict that cooler or wealthier economies will be unaffected or even see benefits from higher temperatures. However, a new study co-authored by researchers from the University of Cambridge suggests that virtually all countries—whether rich or
