Published Ready for the storm: Researchers analyze infrastructure, demographics to see where tornadoes are most disruptive
(via sciencedaily.com) Original source Researchers examined demographics, infrastructure and more than seven decades of weather data to determine which places in Kentucky are most vulnerable to tornadoes.
Published Drought, soil desiccation cracking, and carbon dioxide emissions: an overlooked feedback loop exacerbating climate change
(via sciencedaily.com) Original source Soil stores 80 percent of carbon on earth, yet with increasing cycles of drought, that crucial reservoir is cracking and breaking down, releasing even more greenhouse gases creating an amplified feedback loop that could accelerate climate change.
Published Summer solstice triggers synchronized beech tree reproduction across Europe
(via sciencedaily.com) Original source A new study has found that the summer solstice acts as a 'starting gun' to synchronize beech tree reproduction across vast distances in Europe, affecting ecosystem functions.
Published History repeats as Coral Bay faces mass loss of coral and fish life
(via sciencedaily.com) Original source A perfect storm of environmental factors has seen a monumental loss of fish and coral life at a popular area of Ningaloo Reef in Western Australia's Gascoyne region -- however research into the event shows there is hope it will recover. In March 2022, during the annual coral spawning event, calm weather and limited tidal movement combined to trap the coral's eggs within Bills Bay, at the town of Coral Bay. This led to an excess of nutrients in the water which consumed more oxygen than usual -- causing massive numbers of fish and corals to die from asphyxiation.
Published India's water problems set to get worse as the world warms
(via sciencedaily.com) Original source Winter storms known as western disturbances that provide crucial snow and rainfall to northern India are arriving significantly later in the year.
Published Study explores impacts of Arctic warming on daily weather patterns in the U.S.
(via sciencedaily.com) Original source Arctic sea ice is shrinking as the world continues to warm, and a new study may provide a better understanding of how the loss of this ice may impact daily weather in the middle latitudes, like the United States.
Published Rock weathering and climate: Low-relief mountain ranges are largest carbon sinks
(via sciencedaily.com) Original source For many hundreds of millions of years, the average temperature at the surface of the Earth has varied by not much more than 20 degrees Celsius, facilitating life on our planet. To maintain such stable temperatures, Earth appears to have a 'thermostat' that regulates the concentration of atmospheric carbon dioxide over geological timescales, influencing global temperatures. The erosion and weathering of rocks are important parts of this 'thermostat.'
Published Antarctica's coasts are becoming less icy
(via sciencedaily.com) Original source Scientists found unexpected evidence the area of polynyas around Antarctica is increasing dramatically, and it follows an intriguing cycle, growing and shrinking roughly every 16 years.
Published In wake of powerful cyclone, remarkable recovery of Pacific island's forests
(via sciencedaily.com) Original source After one of the most intense cyclones in world history tore through the Pacific island of Tanna in Vanuatu, new research showed the resilience of the island's forests.
Published 2020 extreme weather event that brought fires and snow to western US
(via sciencedaily.com) Original source The same weather system that led to the spread of the devastating Labor Day wildfires in 2020 brought record-breaking cold and early-season snowfall to parts of the Rocky Mountains. Now, new research is shedding light on the meteorology behind what happened and the impacts of such an extreme weather event.
Published Researchers use GPS-tracked icebergs in novel study to improve climate models
(via sciencedaily.com) Original source Research unearthed new information to help scientists better understand circulation patterns of ocean water around glaciers. In the summers of 2014 and 2019, a group of pioneers in glacial research attached GPS devices to 13 icebergs and tracked hourly changes in their positions as they passed through Greenland's Ilulissat Icefjord toward the ocean. Study results showed circulation in the primary fjord is greatly affected by freshwater flow from connecting tributary fjords, which is critically important to consider in circulation models.
Published Hurricanes and power grids: Eliminating large-scale outages with a new approach
(via sciencedaily.com) Original source Large scale-power outages caused by tropical cyclones can be prevented almost entirely if a small but critical set of power lines is protected against storm damages, a new study finds. Scientists developed a new method that can be used to identify those critical lines and increase the system's resilience.
Published How climate change risks increase at a national scale as the level of global warming increases
(via sciencedaily.com) Original source Researchers have quantified how climate change risks to human and natural systems increase at a national scale as the level of global warming increases. A collection of eight studies -- all focusing on Brazil, China, Egypt, Ethiopia, Ghana and India -- shows that the risks of drought, flooding, declines in crop yields, and loss of biodiversity and natural capital greatly increase for each additional degree of global warming. The overarching picture for the accrual of climate risk across these countries as global warming increases from 1.5 C to 4 C above pre-industrial levels is presented.
Published Climate change threatens thousands of archaeological sites in coastal Georgia
(via sciencedaily.com) Original source Thousands of historic and archaeological sites in Georgia are at risk from tropical storm surges, and that number will increase with climate change, according to a new study.
Published Study finds drought fuels invasive species after wildfires
(via sciencedaily.com) Original source Scientists uncover the intricate dance between drought, wildfires and invasive species in Southern California's coastal sage scrub ecosystems.
Published Researchers are first to see at-risk bat flying over open ocean
(via sciencedaily.com) Original source On a research cruise focused on marine mammals and seabirds, scientists earned an unexpected bonus: The first-ever documented sighting of a hoary bat flying over the open ocean.
Published Cloud clustering causes more extreme rain
(via sciencedaily.com) Original source Understanding cloud patterns in our changing climate is essential to making accurate predictions about their impact on society and nature. Scientists published a new study that uses a high-resolution global climate model to understand how the clustering of clouds and storms impacts rainfall extremes in the tropics. They show that with rising temperatures, the severity of extreme precipitation events increases.
Published Air pollution hides increases in rainfall
(via sciencedaily.com) Original source In a new study, researchers broke down how human-induced greenhouse gas and aerosol emissions influence rainfall in the United States. Greenhouse gas emissions increase rainfall, while aerosols have a long-term drying effect as well as short-term impacts that vary with the seasons. As aerosols decrease, their long-term drying effect will likely diminish, causing rainfall averages and extremes to rapidly increase.
Published Stronger storms free more nutrients from mud flats
(via sciencedaily.com) Original source If storms become stronger in the future due to climate change, more nitrogen may be released from the bottom of coastal seas.
Published Wildfires linked to surge in mental health-related emergency department visits
(via sciencedaily.com) Original source A new studyshows wildfires lead to an increase of anxiety-related emergency department visits in the western United States, amplifying the concerning parallel trajectory of two escalating public health crises -- mental health and climate change.
