The study shows that heat days are underestimated by up to 30 percent on average over 30 years if the error is not corrected—in other words, only 70 percent of the actual temperature extremes are detected in some regions. Credit: Lukas Brunner Many studies on the climate crisis focus on researching temperature extremes on a global scale. Scientists at the University of Vienna have now uncovered an error in an established…

The polar vortex is a crucial component in cold snaps affecting the Northern Hemisphere. Credit: NASA Global warming caused by increased concentrations of greenhouse gases is already affecting our lives. Scorching summers, more intense heat waves, longer drought periods, more extended floods, and wilder wildfires are consequences linked to this warming. …

Nebraska’s Liang Chen took this photo in the aftermath of a blizzard, while riding back from South Dakota to Lincoln in early 2023. The line graph shows the average annual frequency of blizzards in so-called hotspots from 1980 to 2014 (black), compared with two projections: one based on a conservative estimate of future greenhouse emissions (green), the other under a scenario with more extreme emissions (yellow).

Samsung announced the Galaxy S24 series today. The vanilla Galaxy S24 and the bigger Galaxy S24+ will be powered by the Exynos 2400 chipset in certain markets including Europe. The chipset was technically unveiled in October, but we never leared major details like processor speeds and core clusters. Thankfully now that we got our hands on a Galaxy S24+ we managed to get all of the details. The Exynos 2400 CPU has one ultra-powerful Cortex-X4 core clocked at 3.2 GHz, two Cortex-A720 units, running at 2.9 GHz, and…

Comparison of the forecasting schemes of monthly mean number of clusters for Tropical America in January 2019 and their errors. Top left is the observed number of clusters from WWLLN, top center is the result of the mean scheme, top right is the result of the random selector scheme. Bottom left is the error of the mean scheme, bottom right is the error of the random selector scheme (Error = forecast – observations). Credit: Quarterly Journal of the…

CES has always been the place for weird, out-there gadgets to make their debuts, and this year’s show is no exception. Skyted, a Toulouse, France-based startup founded by former Airbus VP Stéphane Hersen and acoustical engineer Frank Simon, is bringing what look like a pair of human muzzles to CES 2024. Called the “Mobility Privacy Mask” and “Hybrid Silent Mask,” the face-worn accoutrements are designed to “absorb voice frequencies” in noisy environments like plains, trains and rideshares,…

"The sight of rolling dark clouds of sand and dust engulfing everything in their path and turning day into night is one of nature's most intimidating spectacles. It is a costly phenomenon that wreaks havoc everywhere from Northern and Central Asia to sub-Saharan Africa." Ibrahim Thiaw, Executive Secretary, UNCCD. Credit: UNCCD Sand and dust storms are an under-appreciated problem now "dramatically" more frequent in some places…
