Researchers pinpoint when the Vikings came to Canada. It was exactly 1,000 years ago

It's long been known that the Vikings were the first Europeans to make the long journey to the Americas, arriving in what is now Canada sometime around the end of the first millennium. At the L'Anse aux Meadows historical site in Newfoundland, Canada, a 10th or 11th century Viking home is depicted. The settlement is the only confirmed Norse archeological site in the Americas outside of

Sun unleashes powerful X-class solar flare and Earth-bound CME that could spark northern lights for July 4 weekend

The X1.1 eruption briefly disrupted radio communications across the daylight side of Earth, while forecasters now expect the accompanying CME to reach Earth on July 3.

NASA satellite captures wave of warm water hundreds of miles long that signals a devastatingly strong El Niño

This year's El Niño is on track to be among the strongest ever recorded. A wave of warm water and higher-than-usual sea surfaces (red) stretches across the Pacific, a few days before El Niño was declared.

TRIC Robotics: Autonomous UV Robots Protect Strawberries from Diseases and Pests

The American company TRIC Robotics is taking ultraviolet crop protection from laboratory research to commercial-scale farming. Its autonomous machines operate at night in California strawberry fields, treating plants with UV-C light while also mechanically removing insects with a vacuum system. In June 2026, the company reported that two robots operating in a commercial field near Santa Maria c

How we discovered an ancient river landscape beneath the ice

Scientists at Newcastle University are part of a research team that has discovered an ancient river landscape preserved beneath the East Antarctic Ice Sheet. The landscape appears to have been formed by rivers at least 14 million years ago and possibly even before the initial growth of East Antarctic ice around 34 million years ago. It consists of ancient valleys and ridges, not dissimil

162M Americans at risk of extreme heat, plus wildfires rage in Western US

Across the US, 162 million people in 35 states face extreme heat warnings, intensifying through the week, while deadly wildfires rage in the Western US, claiming three firefighters' lives. Nearly 162 million Americans from 35 states are under extreme heat alerts as deadly wildfires continue to burn in the Western US, with the heat expected to intensify during the week. Cities in

Pacific Ocean warming signals the possible return of a strong El Niño

El Niño is a natural climate phenomenon, typically lasting 9-12 months, that has been linked to crop failures, more frequent wildfires and concurrent droughts, increased flood risk, disruptions to fisheries, elevated civil conflict and increased disease risk in various regions. Present forecasts predict a 61% chance of El Niño emerging over May-July 2026 and persisting until at least

WMO recognizes new Arctic temperature record of 38⁰C

 A temperature of 38°C (100.4°F) in the Russian town of Verkhoyansk on 20 June 2020 has been recognized as a new Arctic temperature record by the World Meteorological Organization (WMO). Weather and Climate Extremes Archive reflects changing climate GENEVA, 14 December 2021 (WMO) – A temperature of 38°C (100.4°F) in the Russian town of Verkhoyansk on 20 Jun

NASA Space Image Shows One of Arizona’s Main Bodies of Water ‘Near-Empty’

Satellite images captured by NASA have revealed dramatic water loss at Arizona’s San Carlos Reservoir, one of the state’s largest bodies of water, which now appears “near-empty” after months of drought and water releases. According to NASA’s Earth Observatory, a Landsat image taken on May 22, 2026, shows the reservoir holding just 389 acre-feet of water—“less than 1 percent full”
