Published Scientists vacuum animal DNA from air in a Danish forest
(via sciencedaily.com) Original source Over 60 animal species in three days. That is how many mammals, birds and amphibians researchers found DNA traces from in the air in a Danish forest. The results can pave the way for a new and innovative way of mapping biodiversity.
Published New research method determines health impacts of heat and air quality
(via sciencedaily.com) Original source The planet experienced the hottest day on record earlier this month and climate projections estimate the intensity of heat waves and poor air quality will increase and continue to cause severe impacts. Researchers have refined and expanded a method of data collection to assess their health impacts.
Published Risk of fatal heart attack may double in heat wave and high fine particulate pollution days
(via sciencedaily.com) Original source An analysis of more than 202,000 heart attack deaths between 2015-2020 in a single Chinese province found that days that had extreme heat, extreme cold or high levels of fine particulate matter (PM2.5) air pollution were significantly associated with the risk of death from a heart attack, especially in women and older adults.
Published Long-term changes in waves and storm surges have not impacted global coastlines
(via sciencedaily.com) Original source Changes in ocean wave and storm conditions have not caused long-term impacts on sandy coastlines in the past 30 years, a new study has found.
Published Climate science is catching up to climate change with predictions that could improve proactive response
(via sciencedaily.com) Original source In Africa, climate change impacts are experienced as extreme events like drought and floods. It has now been possible to predict and monitor these climatic events, providing early warning of their impacts on agriculture to support humanitarian and resilience programming in the most food insecure countries of the world.
Published Our favorite vintages and their precarious mountainside homes are at risk due to climate change, environmental scientists warn
(via sciencedaily.com) Original source Tucked into the hillsides of Italy, Portugal, and Spain, some of the world's most famous -- and most difficult to maintain -- vineyards are heralded for their unique flavor profiles and centuries of tradition. But as extreme weather and changing socioeconomic conditions make this so-called 'heroic viticulture' even more challenging, scientists worry these grapes and their cultural histories are at risk. Researchers argue that farmers and scientists must work together to protect some of the world's most celebrated wines.
Published Supercomputer used to simulate winds that cause clear air turbulence
(via sciencedaily.com) Using Japan's most powerful supercomputer, researchers reproduced cases of clear air turbulence around Tokyo. They simulated the fine vortices responsible for this dangerous phenomenon. The usefulness of the simulation in predicting turbulence was confirmed by comparing simulation data with data from aircraft recordings. This research should improve the forecasting of turbulence.
Published Marine heat waves caused mass seabird die-offs, beach surveys show
(via sciencedaily.com) Original source New research uses data collected by coastal residents along beaches from central California to Alaska to understand how seabirds have fared in recent decades. The paper shows that persistent marine heat waves lead to massive seabird die-offs months later.
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 How coral reefs can survive climate change
(via sciencedaily.com) Original source Similar to the expeditions of a hundred or two hundred years ago, the Tara Pacific expedition lasted over two years. The goal: to research the conditions for life and survival of corals. The ship crossed the entire Pacific Ocean, assembling the largest genetic inventory conducted in any marine system to date. The team's 70 scientists from eight countries took around 58,000 samples from the hundred coral reefs studied.
Published Human impact on wildlife even in protected areas
(via sciencedaily.com) Original source The largest long-term standardized camera-trap survey to date finds that human activity impacts tropical mammals living in protected areas and sheds light on how different species are affected based on their habitat needs and anthropogenic stressors.
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 Traditional methods cannot give us the insights we need to understand changing ecosystems
(via sciencedaily.com) Original source If we want to face up to the challenges posed by climate change and other global environmental changes, we need to bring complexity science into the mix with ecology and biodiversity conservation.
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 Conservation policies risk damaging global biodiversity, researchers argue
(via sciencedaily.com) Original source Rewilding, organic farming and the 'nature friendly farming' measures included in some government conservation policies risk worsening the global biodiversity crisis by reducing how much food is produced in a region, driving up food imports and increasing environmental damage overseas.
