Mixing trees and crops can help both farmers and the climate

Maxwell Ochoo’s first attempt at farming was a dismal failure. In Ochieng Odiere, a village near the shores of Kenya’s Lake Victoria, “getting a job is a challenge,” the 34-year-old says. To earn some money and help feed his family, he turned to farming. In 2017, he planted watermelon seeds on his 0.7-hectare plot. Right […]

How does the summer solstice affect animals?

Does it keep them up later? The summer solstice, which marks the longest day of the year in the Northern Hemisphere, happens Sunday (June 20) at 11:32 p.m. EDT (Monday, June 21 at 03:32 UTC). This event happens when Earth’s tilt toward the sun is at its maximum and the sun points directly over the […]

Climate ‘tipping points’ could push us past the point-of-no-return after less than 2 degrees of warming

Knock-on effects could transform the Amazon rainforest into savannah As climate change continues to heat the planet, ice sheets and ocean currents could destabilize each other, leading to a climate domino effect impacting 40% of the world’s population, according to new research. And these effects could be seen at way lower temperatures than previously thought. […]

Dramatic images capture rapid slide of Antarctic glacier

Pine Island Glacier, one of the fastest-shrinking glaciers in Antarctica, hastened its slide into the sea between 2017 and 2020, when one-fifth of its associated ice shelf broke off as massive icebergs, a new study reveals. The glacier sped up another time in recent history, between the 1990s and 2009, when warm ocean currents ate […]

‘Bonanza’ gold veins in rocks finally explained

Gold veins thicker than your arm finally get a geological explanation. Why did some gold prospectors strike it rich with a bonanza gold vein, while others came up empty-handed? The credit may go to nanoparticles. New research reveals that high-grade veins of gold contain clusters of gold nanoparticles, which is important because it explains how […]

Here’s how lightning may help clean the air

An airplane saw thunderstorms create extremely high levels of chemicals called oxidants. Lightning may play an important role in clearing the air of pollutants. A storm-chasing airplane has shown that lightning can forge large amounts of oxidants. These chemicals cleanse the atmosphere by reacting with pollutants such as methane. Those reactions form molecules that dissolve […]
