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 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 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 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 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 Newly planted vegetation accelerates dune erosion during extreme storms, research shows
(via sciencedaily.com) Original source Newly planted vegetation on coastal sand dunes can accelerate erosion from extreme waves.
Published Weather anomalies are keeping insects active longer
(via sciencedaily.com) Original source Extreme weather events have affected moth and butterfly activity more than the average increase in global temperature over the last several decades.
Published Ticks prove resilient to extreme temperatures
(via sciencedaily.com) Original source A recent study shows blacklegged ticks (Ixodes scapularis) are actually really good at surviving extreme cold and heat in nature. Previous lab research suggests that even short periods of especially warm or cold conditions should easily kill ticks, but the a new analysis reveals this is only the case for larval ticks in the environment.
Published Global flash droughts expected to increase in a warming climate
(via sciencedaily.com) Original source Researchers have published new findings on how our warming climate will affect the frequency of flash droughts and the risk to croplands globally.
Published New method predicts extreme events more accurately
(via sciencedaily.com) Original source A new study has used global storm-resolving simulations and machine learning to create an algorithm that can deal separately with two different scales of cloud organization: those resolved by a climate model, and those that cannot be resolved as they are too small. This new approach addresses the missing piece of information in traditional climate model parameterizations and provides a way to predict precipitation intensity and variability more precisely.
Published Simultaneous atmospheric and marine observations directly beneath a violent, Category 5 typhoon in the North-West Pacific
(via sciencedaily.com) Original source Scientists have successfully conducted a simultaneous marine and atmospheric measurements at multiple locations directly beneath a violent, Category 5, which is the strongest class, typhoon in the North-West Pacific, before it reached land.
Published Modular builds may help construction industry weather a perfect storm
(via sciencedaily.com) Original source Engineers have calculated the potential cost savings for builders who opt for modular construction techniques to avoid lengthy and expensive holdups caused by poor weather.
Published How a drought affects trees depends on what's been holding them back
(via sciencedaily.com) Original source Droughts can be good for trees. Certain trees, that is. Contrary to expectation, sometimes a record-breaking drought can increase tree growth. Why and where this happens is the subject of a new article.
Published Eruption of Tonga underwater volcano found to disrupt satellite signals halfway around the world
(via sciencedaily.com) Original source Researchers found that the Hunga-Tonga eruption was associated with the formation of an equatorial plasma bubble in the ionosphere, a phenomenon associated with disruption of satellite-based communications. Their findings also suggest that a long-held atmospheric model should be revised.
Published In years after El Niño, global economy loses trillions
(via sciencedaily.com) Original source Researchers report that the financial toll of the climate pattern known as El Niño can persist for several years and cost trillions in lost income worldwide. The study, which is among the first to evaluate the long-term costs of El Niño, found that the 1982 and 1997 events led to $4.1 trillion and $5.7 trillion in lost income in the five years following them. With El Niño projected to return this year, the researchers project that global economic losses for the 21st century will amount to $84 trillion as climate change potentially amplifies the events' frequency and strength.
Published Extremely hot days are warming twice as fast as average summer days in North-West Europe
(via sciencedaily.com) Original source New study analyzed data on near-surface air temperatures recorded for North-West Europe over the past 60 years. The findings show that the maximum temperature of the hottest days is increasing at twice the rate of the maximum temperature of average summer days. The results highlight the need for urgent action by policy makers to adapt essential infrastructure to the impacts of climate change.
Published Atmospheric research provides clear evidence of human-caused climate change signal associated with CO2 increases
(via sciencedaily.com) Original source New research provides clear evidence of a human 'fingerprint' on climate change and shows that specific signals from human activities have altered the temperature structure of Earth's atmosphere.
Published Prolonged power outages, often caused by weather events, hit some parts of the U.S. harder than others
(via sciencedaily.com) Original source New research found that Americans already bearing the brunt of climate change and health inequities are most at risk of impact by a lengthy power outage.
