Published Mapping the future's sweet spot for clean energy and biodiversity
(via sciencedaily.com) Original source A new study of Joshua trees, kit foxes and solar energy developments highlights the need to consider climate-induced range shifts for species as we expand clean energy.
Published A better handle on the emissions budget for the Paris climate targets
(via sciencedaily.com) Original source Scientists have found a new way to calculate the total carbon emissions consistent with the Paris climate targets of 1.5 degrees Celsius and 2 degrees Celsius of global warming.
Published Good news for coral reef restoration efforts: Study finds 'full recovery' of reef growth within four years
(via sciencedaily.com) Original source While the majority of the world's reefs are now under threat or even damaged potentially beyond repair, a new study offers some encouraging news: efforts to restore coral reefs not only increase coral cover, but they can also bring back important ecosystem functions, and surprisingly fast.
Published New technique may help scientists stave off coral reef collapse
(via sciencedaily.com) Original source Producing coral skeleton components in the easy-to-use soft-bodied sea anemone Nematostella creates a perfect lab system for studying, and eventually helping, corals threatened by a changing climate.
Published New study reveals insight into which animals are most vulnerable to extinction due to climate change
(via sciencedaily.com) Original source In a new study, researchers have used the fossil record to better understand what factors make animals more vulnerable to extinction from climate change. The results could help to identify species most at risk today from human-driven climate change.
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 Loss of nature costs more than previously estimated
(via sciencedaily.com) Original source Researchers propose that governments apply a new method for calculating the benefits that arise from conserving biodiversity and nature for future generations.
Published Eight new deep-sea species of marine sponges discovered
(via sciencedaily.com) Original source Despite marine sponges being widespread on our planet, their biodiversity and distribution is still poorly known. Even though the Mediterranean Sea is the most explored sea on Earth, a study reveals the presence of new sponge species and new records in unexplored habitats such as underwater caves or mountains around the Balearic Islands.
Published Scientists raise the alarm: Too many harbour porpoises die each year in fishing nets
(via sciencedaily.com) Original source In order to keep the population of harbour porpoises in Danish coastal waters stable, only 24 can perish in fishing nets each year. However, over 900 die each year.
Published Airflow dynamics scrub classroom air
(via sciencedaily.com) Original source Accounting for airflow dynamics rather than just airflow volume helped researchers measure an 85% reduction in airborne pathogens inside a working classroom.
Published Microbes impact coral bleaching susceptibility
(via sciencedaily.com) Original source A new study provides insights into the role of microbes and their interaction as drivers of interspecific differences in coral thermal bleaching.
Published Understanding wind and water at the equator key to more accurate future climate projections
(via sciencedaily.com) Original source Getting climate models to mimic real-time observations when it comes to warming is critical -- small discrepancies can lead to misunderstandings about the rate of global warming as the climate changes. A new study that when modeling warming trends in the Pacific Ocean, there is still a missing piece to the modeling puzzle: the effect of wind on ocean currents in the equatorial Pacific.
Published Marine algae implants could boost crop yields
(via sciencedaily.com) Original source Scientists have discovered the gene that enables marine algae to make a unique type of chlorophyll. They successfully implanted this gene in a land plant, paving the way for better crop yields on less land.
Published Global warming is affecting bats' hibernation
(via sciencedaily.com) Original source Global change is altering the physiology of the hibernation and behavior of bats, according to a study carried out over a twenty year period. Given the milder winters we are having, bats are accumulating less fat reserves in autumn, they shorten their hibernation periods and they leave their winter shelter sooner. These changes could alter the migration pattern of bats and the phenology of their seasonal displacements.
Published Nanodevices can produce energy from evaporating tap or seawater
(via sciencedaily.com) Original source Researchers have discovered that nanoscale devices harnessing the hydroelectric effect can harvest electricity from the evaporation of fluids with higher ion concentrations than purified water, revealing a vast untapped energy potential.
Published Herbivores, displaced by ocean warming, threaten subtropical seagrass meadows
(via sciencedaily.com) Original source The findings suggest that subtropical seagrasses are less resilient to heavy grazing from marine herbivores, in part because they receive less sunlight relative to their tropical counterparts. As tropical herbivores move into subtropical waters, overgrazing may prevent subtropical seagrass meadows from persisting in these environments.
Published New deep-sea worm discovered at methane seep off Costa Rica
(via sciencedaily.com) Original source Marine biologists have discovered a new species of deep-sea worm living near a methane seep some 50 kilometers (30 miles) off the Pacific coast of Costa Rica.
Published Key advance toward removing common herbicide from groundwater
(via sciencedaily.com) Original source Chemists are closing in on a new tool for tackling the global problem of weedkiller-tainted groundwater.
Published Research explores the cooling effects of 'scuba-diving' in lizards
(via sciencedaily.com) Original source Anoles are the scuba-diving champions of the lizard world, able to stay underwater for more than 16 minutes. For animals whose body temperature depends on the environment, time spent in a cool running stream can have some tradeoffs, according to new research.
Published Short-term exposure to high levels of air pollution kills 1 million globally every year
(via sciencedaily.com) Original source Every year, more than one million deaths globally occur because of exposure to short-term (hours to days) fine particulate matter (PM2.5) in air pollution, according to a new report, with Eastern Asia reporting more than 50% of deaths attributable to short-term PM2.5 globally.
