Published Conserving wildlife can help mitigate climate change
(via sciencedaily.com) Solving the climate crisis and biodiversity crisis are not separate issues. Animals remove billions of tons of carbon dioxide each year. Restoring species will help limit global warming, new science reveals.
Published SMART warnings could protect communities at risk from flooding
(via sciencedaily.com) Engaging communities in developing a real-time early warning system could help to reduce the often-devastating impact of flooding on people and property -- particularly in mountainous regions where extreme water events are a 'wicked' problem, a new study reveals.
Published How to prepare for ocean acidification, a framework
(via sciencedaily.com) An international research team develops a rubric for governments and policymaking bodies to evaluate preparedness for ocean acidification.
Published Some coastal salt marshes are keeping up with sea level rise -- for now
(via sciencedaily.com) The world's salty, tidal marshes are hotspots of carbon storage and productivity, building up sediments and plant material to stay above sea level. However, as sea level rises at an increasing rate, scientists debate whether it's possible for wetlands to win the race. New research reveals how salt marshes along the U.S. East Coast have responded to accelerating sea level rise by building elevation more quickly to keep pace with the sea over the last century.
Published The Greenland Ice Sheet is close to a melting point of no return
(via sciencedaily.com) A new study using simulations identified two tipping points for the Greenland Ice Sheet: releasing 1000 gigatons of carbon into the atmosphere will cause the southern portion of the ice sheet to melt; about 2500 gigatons of carbon means permanent loss of nearly the entire ice sheet. Having emitted about 500 gigatons of carbon, we're about halfway to the first tipping point.
Published Surprise effect: Methane cools even as it heats
(via sciencedaily.com) Most climate models do not yet account for a recent discovery: methane traps a great deal of heat in Earth's atmosphere, but also creates cooling clouds that offset 30% of the heat.
Published Researchers find clue to help plants grow with low phosphorus levels
(via sciencedaily.com) Phosphorus is a natural mineral found in fertilizer that is essential for plant growth and development, and Earth's agricultural-grade phosphorus reserves are expected to be depleted in 50 to 100 years. A new discovery is changing their understanding of iron toxicity in plants caused by low phosphorus levels.
Published Giant volcanic 'chain' spills secrets on inner workings of volcanoes
(via sciencedaily.com) Volcanic relics scattered throughout the Australian landscape are a map of the northward movement of the continent over a 'hotspot' inside the Earth, during the last 35 million years.
Published Climate change threatens global fisheries
(via sciencedaily.com) The diet quality of fish across large parts of the world's oceans could decline by up to 10 per cent as climate change impacts an integral part of marine food chains, a major study has found.
Published Global natural history initiative builds groundbreaking database to address 21st century challenges
(via sciencedaily.com) A group of natural history museums has mapped the total collections from 73 of the world's largest natural history museums in 28 countries. This is the first step of an ambitious effort to inventory global holdings that can help scientists and decision makers find solutions to urgent, wide-ranging issues such as climate change, food insecurity, human health, pandemic preparedness, and wildlife conservation.
Published Improved wastewater treatment could lead to significant reduction in greenhouse gas emissions
(via sciencedaily.com) New research has shown that methane emissions from urban areas are underestimated by a factor of three to four and that untreated wastewater may be a contributing factor.
Published Phytoplankton blooms offer insight into impacts of climate change
(via sciencedaily.com) The first study into the biological response of the upper ocean in the wake of South Pacific cyclones could help predict the impact of warming ocean temperatures, researchers believe.
Published Geoscientists shed a light on life's evolution 800 million years ago
(via sciencedaily.com) Is nitrate responsible for algae, flowers, and even your neighbors? A team of geoscientists have unearthed evidence that may indicate yes.
Published Sea otters killed by unusual parasite strain
(via sciencedaily.com) An unusually severe form of toxoplasmosis killed four sea otters and could pose a threat to other marine wildlife and humans, finds a new study.
Published Sea ice will soon disappear from the Arctic during the summer months -- and it has happened before
(via sciencedaily.com) In a new study, an international team of researchers warn that the Arctic Sea ice may soon be a thing of the past in the summer months. This may have consequences for both the climate and ecosystems. Ten thousand years ago, the ice melted at temperatures similar to those we have today.
Published Researchers get to the 'bottom' of how beetles use their butts to stay hydrated
(via sciencedaily.com) Beetles are champions at surviving in extremely dry environments. In part, this property is due to their ability to suck water from the air with their rear ends. A new study explains just how. Beyond helping to explain how beetles thrive in environments where few other animals can survive, the knowledge could eventually be used for more targeted and delicate control of global pests such as the grain weevil and red flour beetle.
Published Human and ocean health impacts of ocean plastics
(via sciencedaily.com) Researchers from the fields of healthcare, ocean science, and social science have collaborated to quantify plastic's considerable risks to all life on Earth. The Minderoo-Monaco Commission on Plastics and Human Health report presents a comprehensive analysis showing plastics as a hazard at every stage of their life cycle.
Published 'Rock stars' solve long-standing diamond conundrum
(via sciencedaily.com) Two researchers have used a standard laptop computer and a humble piece of rock -- from the 'waste pile' of a diamond mine -- to solve a long-held geological conundrum about how diamonds formed in the deep roots of the earth's ancient continents.
Published Going beyond English is critical for conservation
(via sciencedaily.com) Research in languages other than English is critically important for biodiversity conservation and is shockingly under-utilized internationally, according to an international research team.
Published Biodiversity amid climate change
(via sciencedaily.com) Fewer parasites in U.S. waters might be seen by many as a good thing, but a biologist says the trend signals potential danger for fish and other wildlife.
