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 Researchers finds a way to reduce the overheating of semiconductor devices
(via sciencedaily.com) Original source Scientists have identified a method for improving the thermal conductivity of thin metal films in semiconductors using surface waves for the first time in the world.
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 Thermal energy stored by land masses has increased significantly
(via sciencedaily.com) Original source There are many effects of climate change. Perhaps the most broadly known is global warming, which is caused by heat building up in various parts of the Earth system, such as the atmosphere, the ocean, the cryosphere and the land. 89 percent of this excess heat is stored in the oceans, with the rest in ice and glaciers, the atmosphere and land masses (including inland water bodies). An international research team has now studied the quantity of heat stored on land, showing the distribution of land heat among the continental ground, permafrost soils, and inland water bodies. The calculations show that more than 20 times as much heat has been stored there since the 1960s, with the largest increase being in the ground.
Published The next generation of solar energy collectors could be rocks
(via sciencedaily.com) Original source The next generation of sustainable energy technology might be built from some low-tech materials: rocks and the sun. Using a new approach known as concentrated solar power, heat from the sun is stored then used to dry foods or create electricity. A team has found that certain soapstone and granite samples from Tanzania are well suited for storing this solar heat, featuring high energy densities and stability even at high temperatures.
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 Quantum scientists accurately measure power levels one trillion times lower than usual
(via sciencedaily.com) Original source Scientists have developed a nanodevice that can measure the absolute power of microwave radiation down to the femtowatt level at ultra-low temperatures -- a scale trillion times lower than routinely used in verifiable power measurements. The device has the potential to significantly advance microwave measurements in quantum technology.
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 Sensors that operate at high temperatures and in extreme environments
(via sciencedaily.com) Original source Researchers have developed a new reliable and durable sensor that can work in temperatures as high as 900 degrees Celsius or 1,650 degrees Fahrenheit and can be used in multiple industries.
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 'Improved' cookstoves emit more ultrafine particles than conventional stoves
(via sciencedaily.com) Original source Improved cookstoves, which are widely used for cooking in developing countries, produce twice as many harmful ultrafine air pollution particles (PM0.1) as conventional stoves, according to a new study.
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.
Published The science behind the life and times of the Earth's salt flats
(via sciencedaily.com) Original source Researchers have characterized two different types of surface water in the hyperarid salars -- or salt flats -- that contain much of the world's lithium deposits. This new characterization represents a leap forward in understanding how water moves through such basins, and will be key to minimizing the environmental impact on such sensitive, critical habitats.
Published 120-year-old storm's secrets key to understanding weather risks
(via sciencedaily.com) Original source The conversion of handwritten weather records into digital information will help weather better understand future weather risks.
