Published Three things to know: Climate change's impact on extreme-weather events
(via sciencedaily.com)
Original source 
Researchers found that the effects of climate change on the intensity, frequency, and duration of extreme weather events, like wildfires, could lead to massive increases in all three.
Published Birds raise fewer young when spring arrives earlier in a warming world
(via sciencedaily.com)
Original source 
A new study of North American songbirds finds that birds can't keep up with the earlier arrival of spring caused by climate change. As a result, they're raising fewer young. By the end of the 21st century, climate change will cause springlike weather to begin 25 days earlier, but birds will only breed about seven days earlier. That change could lead to an average reduction of 12% in breeding productivity for songbird species.
Published New study reveals abrupt shift in tropical Pacific climate during Little Ice Age
(via sciencedaily.com)
Original source 
An El Niño event has officially begun. The climate phenomenon, which originates in the tropical Pacific and occurs in intervals of a few years will shape weather across the planet for the next year or more and give rise to various climatic extremes. El Niño-like conditions can also occur on longer time scales of decades or centuries. This has been shown to have occurred in the recent past.
Published Scientists propose new strategy for modern sails to help shipping sector meet its carbon reduction goals
(via sciencedaily.com)
Original source 
Researchers have identified a strategy that can offset the random and unpredictable nature of weather conditions that threaten carbon emission reduction efforts in the shipping sector.
Published Freely available risk model for hurricanes, tropical cyclones
(via sciencedaily.com)
Original source 
As human-driven climate change amplifies natural disasters, hurricanes and typhoons stand to increase in intensity. Until now, there existed very few freely available computer models designed to estimate the economic costs of such events, but a team of researchers has recently announced the completion of an open-source model that stands to help countries with high tropical cyclone risks better calculate just how much those storms will impact their people and their economies.
Published First detection of crucial carbon molecule
(via sciencedaily.com)
Original source 
Scientists detect a new carbon compound in space for the first time. Known as methyl cation (pronounced cat-eye-on) (CH3+), the molecule is important because it aids the formation of more complex carbon-based molecules. Methyl cation was detected in a young star system, with a protoplanetary disk, known as d203-506, which is located about 1,350 light-years away in the Orion Nebula.
Published New nationwide modeling points to widespread racial disparities in urban heat stress
(via sciencedaily.com)
Original source 
Using a combination of satellite data and modeling to study the temperatures and humidity people might feel in urban areas, researchers have pinpointed who in the U.S. is most vulnerable to heat stress.
Published City buildings could blow air taxi future off course
(via sciencedaily.com)
Original source 
Air taxis may be coming to our cities in the near future, but a new study warns regulations will need to address dangerous wind gusts around city buildings and other urban infrastructure.
Published Einstein and Euler put to the test at the edge of the Universe
(via sciencedaily.com)
Original source 
The cosmos is a unique laboratory for testing the laws of physics, in particular those of Euler and Einstein. Euler described the movements of celestial objects, while Einstein described the way in which celestial objects distort the Universe. Since the discovery of dark matter and the acceleration of the Universe's expansion, the validity of their equations has been put to the test: are they capable of explaining these mysterious phenomena? A team has developed the first method to find out. It considers a never-before-used measure: time distortion.
Published Flooding tackled by helping citizens take action
(via sciencedaily.com)
Original source 
Scientists have developed a new method that empowers citizens to identify solutions to climate change threats.
Published Never-before-seen way to annihilate a star
(via sciencedaily.com)
Original source 
Astronomers studying a powerful gamma-ray burst, may have detected a never-before-seen way to destroy a star. Unlike most GRBs, which are caused by exploding massive stars or the chance mergers of neutron stars, astronomers have concluded that this GRB came instead from the collision of stars or stellar remnants in the jam-packed environment surrounding a supermassive black hole at the core of an ancient galaxy.
Published Wildfire smoke downwind affects health, wealth, mortality
(via sciencedaily.com)
Original source 
Smoke particulates from wildfires could cause between 4,000 and 9,000 premature deaths and cost between $36 to $82 billion per year in the United States, according to new research.
Published A Tongan volcano plume produced the most intense lightning rates ever detected
(via sciencedaily.com)
Original source 
New research showed that the plume emitted by the Hunga Volcano eruption in 2022 created the highest lightning flash rates ever recorded on Earth, more than any storm ever documented.
Published Researchers demystify the unusual origin of the Geminids meteor shower
(via sciencedaily.com)
Original source 
Princeton researchers used observations from NASA's Parker Solar Probe mission to deduce that it was likely a violent, catastrophic event -- such as a high-speed collision with another body or a gaseous explosion -- that created the Geminids meteoroid stream. Mysteries surrounding the origin of the Geminids have long fascinated scientists because, while most meteor showers are created when a comet emits a tail of ice and dust, the Geminids stem from an asteroid -- a chunk of rock that normally does not produce a tail. Until now, this unusual meteoroid stream had only been studied from Earth.
Published Discovery of white dwarf pulsar sheds light on star evolution
(via sciencedaily.com)
Original source 
The discovery of a rare type of white dwarf star system provides new understanding into stellar evolution.
Published 10-year countdown to sea-ice-free Arctic
(via sciencedaily.com)
Original source 
Research team predicts Arctic without ice by the end of 2030s if current increasing rate of greenhouse gas emission continues.
Published Astronomers discover new link between dark matter and clumpiness of the universe
(via sciencedaily.com)
Original source 
Researchers reveal a theoretical breakthrough that may explain both the nature of invisible dark matter and the large-scale structure of the universe known as the cosmic web. The result establishes a new link between these two longstanding problems in astronomy, opening new possibilities for understanding the cosmos. The research suggests that the 'clumpiness problem,' which centres on the unexpectedly even distribution of matter on large scales throughout the cosmos, may be a sign that dark matter is composed of hypothetical, ultra-light particles called axions. The implications of proving the existence of hard-to-detect axions extend beyond understanding dark matter and could address fundamental questions about the nature of the universe itself.
Published Sun's coldest region stores secret to heating million-degree corona
(via sciencedaily.com)
Original source 
Researchers have unveiled the discovery of intense wave energy from a relatively cool, dark and strongly magnetized plasma region on the Sun, capable of traversing the solar atmosphere and maintaining temperatures of a million degrees Kelvin inside the corona. Researchers say the finding is the latest key to unraveling a host of related mysteries pertaining to Earth's nearest star.
