Published New research shows soil microorganisms could produce additional greenhouse gas emissions from thawing permafrost
(via sciencedaily.com) Original source As the planet has warmed, scientists have long been concerned about the potential for harmful greenhouse gasses to seep out of thawing Arctic permafrost. Recent estimates suggest that by 2100 the amount of carbon dioxide and methane released from these perpetually frozen lands could be on par with emissions from large industrial countries. However, new research led by a team of microbiome scientists suggests those estimates might be too low.
Published Global activity of seafloor biodiversity mapped
(via sciencedaily.com) Original source A team of scientists has used artificial intelligence (AI) to map the activities of seafloor invertebrate animals, such as worms, clams and shrimps, across all the oceans of the world.
Published Warmer wetter climate predicted to bring societal and ecological impact to the Tibetan Plateau
(via sciencedaily.com) Original source According to a paper, climate and weather predictions of increased rainfall will lead to an exponential expansion of land-locked lakes on the Tibetan Plateau, resulting in major land loss and related economic, environmental and climatic impacts.
Published The global clean water crisis looms large
(via sciencedaily.com) Original source Water scarcity will intensify with climate and socioeconomic change, disproportionately impacting populations located in the Global South.
Published Rising temperatures will significantly reduce streamflow in the upper Colorado river basin as groundwater levels fall
(via sciencedaily.com) Original source The Colorado River makes life possible in many Western cities and supports agriculture that sustains people throughout the country. Most of the river's water begins as snowmelt from the mountainous watersheds of Colorado, Utah, and Wyoming, and a warming climate will drastically reduce these streamflows, new research finds.
Published Future climate impacts put whale diet at risk
(via sciencedaily.com) Original source A new study predicts future climate change impacts could disrupt the krill-heavy diet that humpback whales in the southern hemisphere consume.
Published Beach erosion will make Southern California coastal living five times more expensive by 2050, study predicts
(via sciencedaily.com) Original source Southern California's iconic sandy coastlines are vanishing at an alarming rate, and it's a warning sign for coastal communities worldwide, new research suggests.
Published Social networks can influence perception of climate-change risk
(via sciencedaily.com) Original source Short but severe episodes of flooding from hurricanes in Texas and Florida triggered a nationwide increase in flood insurance sign-ups depending on how socially connected a county was to the flooded counties.
Published Smoke covered 70% of California during biggest wildfire years
(via sciencedaily.com) Original source As much as 70 percent of California was covered by wildfire smoke during parts of 2020 and 2021, according to a new study.
Published Conservation of nature's strongholds needed to halt biodiversity loss
(via sciencedaily.com) Original source To achieve global biodiversity targets, conservationists and governments must prioritize the establishment and effective management of large, interconnected protected areas with high ecological integrity, researchers argue in a new essay.
Published Alaska's rusting waters: Pristine rivers and streams turning orange
(via sciencedaily.com) Original source Dozens of Alaska's rivers and streams are turning orange. The staining could be the result of minerals exposed by thawing permafrost and climate change, finds a new study.
Published Regional differences in bird diversity in agroforestry systems
(via sciencedaily.com) Original source The diversity and ecological functionality of bird communities in tropical agroforestry systems are shaped by the surrounding landscape, in particular the extent and composition of the forest.
Published Night-time heat significantly increases the risk of stroke
(via sciencedaily.com) Original source Researchers show that nocturnal heat significantly increases the risk of stroke. The findings can contribute to the development of preventive measures: With them, the population can better protect themselves against the risks of climate change with increasingly frequent hot nights. In addition, knowledge of the consequences of hot nights can improve patient care.
Published Rabies outbreaks in Costa Rica cattle linked to deforestation
(via sciencedaily.com) Original source Deforestation in Costa Rica raises the risk of cattle becoming infected with rabies by vampire bats, finds a new study.
Published Warming climate intensifies flash droughts worldwide
(via sciencedaily.com) Original source Sudden, severe dry spells known as flash droughts are rising in intensity around the world, with a notable exception in mountainous Central Asia, where flash drought extent is shrinking, according to new research. Heat and changes to precipitation patterns caused by a warming climate are driving these trends, the study found.
Published A rise in sea urchins and related damage to kelp forests impacts Oregon's gray whales and their food
(via sciencedaily.com) Original source A recent boom in the purple sea urchin population off the southern Oregon Coast appears to have had an indirect and negative impact on the gray whales that usually forage in the region, a new study shows.
Published The impacts of climate change on food production
(via sciencedaily.com) Original source A new study shows that climate change has led to decreased pollen production from plants and less pollen diversity than previously thought, which could have a significant impact on food production.
Published Unraveling the drought dilemma: Can reservoirs be a carbon source?
(via sciencedaily.com) Original source A team delves into the spatiotemporal patterns of water volume and total organic carbon concentration of agricultural reservoirs.
Published U.S. drought-monitoring system outpaced by climate changes
(via sciencedaily.com) Original source A new study reports that the U.S. Drought Monitor's weekly maps of nationwide drought conditions -- which help direct emergency federal aid -- have captured the steady march of climate change, but the Drought Monitor has itself failed to adapt to that reality. Areas of the country are spending more and more time in severe drought conditions the Drought Monitor still considers to be rare occurrences. The consequences could be that swaths of the country -- particularly in the West -- may not receive aid in keeping with the enhanced risk of drought as periodic emergencies become persistent new realities.
Published Cloudy waters causes African fish to develop bigger eyes
(via sciencedaily.com) Original source Variations in water quality can impact the development of the visual system of one species of African fish, suggests a new study.
