North Atlantic spring storms have grown more common since 1940, analysis reveals
North Atlantic spring storms have grown more common since 1940, analysis reveals Sadie Harley Scientific Editor Andrew Zinin Lead Editor Storm Dave, which swept across northern Europe over the Easter weekend, is an example of what new research from the University of Gothenburg has revealed. Spring storms forming over the North Atlantic have become more common than they were 80 years ago, and this is due to climate change. In the Northern Hemisphere, storm seasons follow a seasonal cycle.
Hydrodynamically engineered Indigenous arrows skip on water for waterfowl hunting
Announce Type: new Abstract: Across the Northern Hemisphere, Indigenous hunters developed arrows capable of skipping across the water surface to strike waterfowl. Archaeological and ethnographic records reveal remarkably similar projectile designs spanning millennia and geographically distant cultures, suggesting a convergent technological solution.
The enigmatic summer phenomenon shining from the edge of space
With no recorded sightings before 1885, noctilucent clouds have been linked to volcanoes, pollution or climate changeAs summer arrives in the northern hemisphere, so do the noctilucent clouds – hopefully. These high-altitude formations are as enigmatic as they are beautiful. Their name derives from Latin, meaning “night shining”.

Hotter summers and colder winters: El Nino set to intensify extreme weather, scientist says
Hotter summers and colder winters: El Nino set to intensify extreme weather, scientist says Issued on: A climate scientist has told FRANCE 24 that we should all watch out and prepare for the strong possibility of an extremely hot summer in the northern hemisphere in the coming months. The World Meteorological Organization is warning that the El Nino phenomenon is set to develop in the Pacific between now and the end of August, increasing the risk of extreme weather events.

Atmospheric wave theory falls short in explaining rising extreme weather, study suggests
Atmospheric wave theory falls short in explaining rising extreme weather, study suggests Lisa Lock Scientific Editor Robert Egan Associate Editor Across much of the northern hemisphere, extreme weather events like heat waves and heavy precipitation have increased in frequency and severity over the last several decades. A new study from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) shows that one proposed partial explanation, so-called "quasiresonant...
Image: Colorful, chaotic Jupiter
Image: Colorful, chaotic Jupiter Lisa Lock Scientific Editor Andrew Zinin Lead Editor NASA's Juno spacecraft captured this color-enhanced view of Jupiter's northern hemisphere during its 61st close flyby of the giant planet on May 12, 2024. Citizen scientist Gary Eason made this image using raw data from the JunoCam instrument, applying digital processing techniques to enhance color and clarity. It provides a detailed view of chaotic clouds and cyclonic storms in an area known to scientists...
Earth has a mysterious triple symmetry that may influence its climate
A line that runs through Africa, Europe, Alaska and both poles divides Earth into two halves that reflect the same amount of light – and this newly discovered symmetry may play a critical role in the planet’s climate. It was previously known that the northern and southern hemispheres have almost equal reflectivity, or albedo, but Jianhao Zhang at the National Oceanic and Atmospheric Administration in the US and his colleagues have now uncovered a second line of symmetry along the 27° east...
Understanding Earth's hidden east-west symmetry could improve climate models
June 4, 2026 report Understanding Earth's hidden east-west symmetry could improve climate models Paul Arnold Author Gaby Clark Scientific Editor Robert Egan Associate Editor Earth is divided into two halves: the Northern and Southern Hemispheres. Both reflect equal amounts of sunlight (albedo) even though they have different landmasses and weather patterns, especially cloud distribution. Why this is so is an ongoing mystery waiting to be solved.
Attribution constraints reveal stronger future intensification of the upper‑level Hadley circulation
Attribution constraints reveal stronger future intensification of the upper‑level Hadley circulation Gaby Clark Scientific Editor Robert Egan Associate Editor The Hadley circulation, a key atmospheric conveyor belt transporting heat and moisture from the tropics to the subtropics, directly influences subtropical aridity, the positions of tropical rainfall belts, and extreme weather risks. However, climate models have long shown inconsistencies in simulating its upper-level intensity...
