Published Everest mountaineer's letters digitized
(via sciencedaily.com) Original source Letters written by the famous mountaineer George Mallory have been made available to a global audience for the first time, in the centenary year of his fatal attempt to scale Everest.
Published AI weather forecasts captured Ciaran's destructive path
(via sciencedaily.com) Original source The study highlights the rapid progress and transformative potential of AI in weather prediction.
Published Lemur's lament: When one vulnerable species stalks another
(via sciencedaily.com) Original source What can be done when one threatened animal kills another? Scientists studying critically endangered lemurs in Madagascar confronted this difficult reality when they witnessed attacks on lemurs by another vulnerable species, a carnivore called a fosa.
Published Weather prediction models can also forecast satellite displacements
(via sciencedaily.com) Original source Researchers have found that modern weather models can accurately predict the energy that Earth emits and reflects into space, which directly affects the movements of low Earth-orbiting (LEO) satellites. By leveraging these models, the researchers gained insights into how LEO satellites respond to weather events below, such as tropical cyclones with tall and reflective clouds.
Published New research shines a light on how expert mapmakers see the world differently
(via sciencedaily.com) Original source Researchers have found differences between experienced Ordnance Survey (OS) mapmakers and novices in the way that they interpret aerial images for mapmaking, which could lead to improved training processes for new recruits.
Published Climate change will increase value of residential rooftop solar panels across US, study shows
(via sciencedaily.com) Original source Climate change will increase the future value of residential rooftop solar panels across the United States by up to 19% by the end of the century, according to a new study.
Published Data-driven music: Converting climate measurements into music
(via sciencedaily.com) Original source A geo-environmental scientist from Japan has composed a string quartet using sonified climate data. The 6-minute-long composition -- entitled 'String Quartet No. 1 'Polar Energy Budget'-- is based on over 30 years of satellite-collected climate data from the Arctic and Antarctic and aims to garner attention on how climate is driven by the input and output of energy at the poles.
Published Ice age climate analysis reduces worst-case warming expected from rising CO2
(via sciencedaily.com) Original source A detailed reconstruction of climate during the most recent ice age, when a large swath of North America was covered in ice, provides information on the relationship between CO2 and global temperature. Results show that while most future warming estimates remain unchanged, the absolute worst-case scenario is unlikely.
Published East coast mussel shells are becoming more porous in warming waters
(via sciencedaily.com) Original source Researchers have found that over the last 120 years, the porosity -- or small-scale holes -- in mussel shells along the East Coast of the United States has increased, potentially due to warming waters. The study analyzed modern mussel shells in comparison to specimens in the Museum's historic collection.
Published 38 trillion dollars in damages each year: World economy already committed to income reduction of 19 % due to climate change
(via sciencedaily.com) Original source Even if CO2 emissions were to be drastically cut down starting today, the world economy is already committed to an income reduction of 19% until 2050 due to climate change, a new study finds. These damages are six times larger than the mitigation costs needed to limit global warming to two degrees. Based on empirical data from more than 1,600 regions worldwide over the past 40 years, scientists assessed future impacts of changing climatic conditions on economic growth and their persistence.
Published Paradox of extreme cold events in a warming world
(via sciencedaily.com) Original source The Warm Arctic-Cold Continent (WACC) phenomenon is the puzzling combination of Arctic warming and extreme coldness in specific mid-latitude regions. However, the progression of WACC events remains unclear amidst global warming. Scientists have now predicted a sharp decline in the WACC phenomenon post-2030s, affecting extreme weather events. These findings offer critical insights for communities, scientists, and policymakers to refine climate models and strategies and battle climate change.
Published Making crops colorful for easier weeding
(via sciencedaily.com) Original source To make weeding easier, scientists suggest bioengineering crops to be colorful or to have differently shaped leaves so that they can be more easily distinguished from their wild and weedy counterparts. This could involve altering the crops' genomes so that they express pigments that are already produced by many plants, for example, anthocyanins, which make blueberries blue, or carotenoids, which make carrots orange. Then, they say, weeding robots could be trained to remove only the weeds using machine learning.
Published CO2 worsens wildfires by helping plants grow
(via sciencedaily.com) Original source By fueling the growth of plants that become kindling, carbon dioxide is driving an increase in the severity and frequency of wildfires, according to a new study.
Published Yellowstone Lake ice cover unchanged despite warming climate
(via sciencedaily.com) Original source While most lakes around the world are experiencing shorter durations of ice cover, the length of time that Yellowstone Lake is covered by ice each year has not changed in the past century, possibly due to increased snowfall.
Published A single atom layer of gold: Researchers create goldene
(via sciencedaily.com) Original source For the first time, scientists have managed to create sheets of gold only a single atom layer thick. The material has been termed goldene. According to researchers, this has given the gold new properties that can make it suitable for use in applications such as carbon dioxide conversion, hydrogen production, and production of value-added chemicals.
Published Oxidant pollutant ozone removes mating barriers between fly species
(via sciencedaily.com) Original source Researchers show that ozone levels, such as those found in many places on hot summer days today, destroy the sex pheromones of fruit fly species. As a result, some natural mating boundaries maintained by species-specific pheromones no longer exist. The research team has shown in experiments that flies of different species mate when exposed to ozone and produce hybrid offspring. Since most of these offspring are unable to reproduce, the results could provide another explanation for the global decline of insects.
Published Food security in developed countries shows resilience to climate change
(via sciencedaily.com) Original source A study has found that market forces have provided good food price stability over the past half century, despite extreme weather conditions.
Published Scientist helps link climate change to Madagascar's megadrought
(via sciencedaily.com) Original source A team reveals a clear link between human-driven climate change and the years-long drought currently gripping southern Madagascar.
Published 'Teacher Toads' can save native animals from toxic cane toads
(via sciencedaily.com) Original source Scientists from Macquarie University have come up with an innovative way to stop cane toads killing native wildlife by training goannas to avoid eating the deadly amphibians.
Published Research examines tweets during Hurricane María to analyze social media use during disasters
(via sciencedaily.com) Original source Understanding how social media is used during a disaster can help with disaster preparedness and recovery for future events.
