The first assimilation of CryoSat-2 summer observations provides accurate estimates of Arctic sea ice thickness
Scientists have improved a data assimilation system for better estimating Arctic summer sea ice thickness (SIT) by assimilating satellite-based summer SIT and ice concentration data with an incremental analysis update (IAU) approach. Their study show.....»»

Q&A: Public opinion research in changing times
Between the July assassination attempt on Donald Trump, President Biden dropping out of the race and Kamala Harris becoming the Democratic nominee, this past summer was unlike any other period in the 2024 presidential race. But the faculty, staff, an.....»»
Arctic weather satellite"s first images capture Storm Boris
Just a month after its launch, ESA's Arctic Weather Satellite has already delivered its first images, notably capturing Storm Boris, which has been wreaking havoc across central Europe......»»
Can captive tigers be part of the effort to save wild populations?
Captive tigers in the United States outnumber those living in the wild. The World Wildlife Federation estimates around 5,000 of the big cats reside in the U.S., mostly owned by private citizens......»»
How humans are affecting the Northern Hemisphere"s wind patterns
The summer of 2024 was the hottest on record and, unfortunately, this came as no surprise. Summers have been getting hotter and drier around the world, including in the Northern Hemisphere, leading to intense droughts and heat waves in North America.....»»
Observations provide crucial insights into the nature of a white dwarf–brown dwarf binary
Using the Hubble Space Telescope (HST), astronomers have performed spectrophotometric observations of an eclipsing white dwarf–brown dwarf binary known as WD1032+011. Results of their observational campaign, published September 10 on the preprint s.....»»
Arctic warming may fuel ice formation in clouds, observations suggest
The Arctic frequently experiences temperatures that support the formation of mixed-phase clouds that contain supercooled liquid droplets and ice crystals. The composition of such clouds plays a crucial role in the region's energy balance and climate.....»»
What the jet stream and climate change had to do with the hottest summer on record
Summer 2024 was officially the Northern Hemisphere's hottest on record. In the United States, fierce heat waves seemed to hit somewhere almost every day......»»
Second-gen Starlink satellites leak 30 times more radio interference, threatening astronomical observations
Observations with the LOFAR (Low Frequency Array) radio telescope last year showed that first generation Starlink satellites emit unintended radio waves that can hinder astronomical observations......»»
Summer 2024 Was the Hottest Ever Measured, Beating Last Year
The year 2024 could easily shape up to be the hottest ever measured, climate scientists say.....»»
The Arctic Seed Vault Shows the Flawed Logic of Climate Adaptation
The difficulties of the Svalbard seed repository illustrate why we need to prevent climate disaster rather than plan for it.....»»
In French Polynesia, boom in whale-based tourism sparks concern
A giant whale stole the show at the Summer Olympic Games, shooting out of the water as athletes competed in women's surfing semi-finals on the French Pacific island of Tahiti last month......»»
Students prefer teacher feedback over AI feedback, research finds
Feedback plays a crucial role in learning, helping individuals to understand and improve their performance, yet globally large and diverse student populations often mean that providing timely and personalized observations can be a challenge......»»
Slow-moving landslides a growing, but ignored, threat to mountain communities
As urban centers in mountainous regions grow, more people are driven to build on steeper slopes prone to slow-moving landslides, a new study finds. Slow-moving landslides are frequently excluded from estimates of landslide risk, but they could threat.....»»
Pollen affects cloud formation and precipitation patterns, researchers find
Ground-based and satellite observations in the United States show that increased pollen concentrations in spring lead to more cloud ice and more precipitation—even at temperatures between minus 15 and minus 25 degrees Celsius......»»
Low-noise amplifiers aboard the Arctic Weather Satellite
The Arctic Weather Satellite (AWS) of the European Space Agency (ESA) was sent on its journey to a polar orbit 600 km above the Earth on August 16, 2024. On board: four low-noise amplifiers (LNAs) from the Fraunhofer Institute for Applied Solid State.....»»
Black hole pairs may unveil new particles
In a paper published in Physical Review Letters this week, physicists from Amsterdam and Copenhagen argue that close observations of merging black hole pairs may unveil information about potential new particles. The research combines several new disc.....»»
Portugal battles ferocious wildfires as toll rises to seven
Thousands of firefighters on Tuesday battled wildfires in Portugal that have killed seven people and burnt more land in a matter of days than the rest of the summer combined......»»
Q&A: Is the "lung float test" accurate? Law professor is leading an effort to discredit "bad science"
Over the centuries, a flawed and controversial forensics tool known as the "floating lung test" or lung float test has sent innocent women accused of infanticide to the gallows......»»
Pinpointing the key size for rapid tropical cyclone intensification
Accurately predicting how rapidly tropical cyclones (TCs) will intensify is a significant challenge due to the complex processes involved. Limited observations show that smaller TCs tend to intensify faster, suggesting a simple linear relationship be.....»»
