Antarctica's ice melt isn't consistent, new analysis shows

Mon, 02/01/2021 - 18:59
Antarctic ice is melting, contributing massive amounts of water to the world's seas and causing them to rise - but that melt is not as linear and consistent as scientists previously thought, a new analysis of 20 years' worth of satellite data indicates.

Wellbeing benefits of wetlands

Mon, 02/01/2021 - 16:32
Australians love their beaches, and now a new study also confirms the broad appeal of other coastal assets such as tidal wetlands, nature trails and protected areas including bird and dolphin sanctuaries.

Research catches up to world's fastest-growing plant

Mon, 02/01/2021 - 16:08
Wolffia, also known as duckweed, is the fastest-growing plant known, but the genetics underlying this strange little plant's success have long been a mystery to scientists. New findings about the plant's genome explain how it's able to grow so fast.

Arctic warming and diminishing sea ice are influencing the atmosphere

Fri, 01/29/2021 - 18:09
Researchers have resolved for the first time, how the environment affects the formation of nanoparticles in the Arctic. The results give additional insight into the future of melting sea ice and the Arctic atmosphere. Until recent studies, the molecular processes of particle formation in the high Arctic remained a mystery.

Past river activity in northern Africa reveals multiple Sahara greenings

Fri, 01/29/2021 - 18:09
The analysis of sediment cores from the Mediterranean Sea combined with Earth system models tells the story of major environmental changes in North Africa over the last 160,000 years.

Hurricanes and typhoons moving 30km closer to coasts every decade

Fri, 01/29/2021 - 17:50
High-intensity tropical cyclones have been moving closer to coasts over the past 40 years, potentially causing more destruction than before.

Forty years of coral spawning captured in one place for the first time

Fri, 01/29/2021 - 16:05
Efforts to understand when corals reproduce have been given a boost thanks to a new resource that gives scientists open access to more than forty years' worth of information about coral spawning.

Human activity caused the long-term growth of greenhouse gas methane

Fri, 01/29/2021 - 16:05
Decadal growth rate of methane in the atmosphere varied dramatically over the past 30 yeas with three distinct periods of slowed (1988-1998), quasi-stationary (1999-2006) and renewed (2007-2016) phases. An inverse analysis with atmospheric chemistry transport modeling explained these variations consistently. While emissions from oil and gas exploitation and natural climate events caused the slowed growth and the temporary pause, those from coal mining in China and livestock farming in the tropics drove the renewed growth.

Aerosol particles cool the climate less than we thought

Thu, 01/28/2021 - 22:56
The impact of atmospheric aerosols on clouds and climate may be different than previously thought.

Loggerhead sea turtles lay eggs in multiple locations to improve reproductive success

Thu, 01/28/2021 - 22:56
Although loggerhead sea turtles return to the same beach where they hatched to lay their eggs, a new study finds individual females lay numerous clutches of eggs in locations miles apart from each other which increases the odds that some of their offspring will survive.

Marine heatwaves becoming more intense, more frequent

Thu, 01/28/2021 - 22:56
When thick, the surface layer of the ocean acts as a buffer to extreme marine heating -- but a new study shows this 'mixed layer' is becoming shallower each year. The thinner it becomes, the easier it is to warm. The new work could explain recent extreme marine heatwaves, and point at a future of more frequent and destructive ocean warming events as global temperatures continue to climb.

US must unify atmospheric biology research or risk national security, experts urge

Thu, 01/28/2021 - 20:46
Global circulating winds can carry bacteria, fungal spores, viruses and pollen over long distances and across national borders, but the United States is ill-prepared to confront future disease outbreaks or food-supply threats caused by airborne organisms, says a new article.

635 million-year-old fungi-like microfossil that bailed us out of an ice age discovered

Thu, 01/28/2021 - 16:11
A team of scientists has discovered the remains of a fungi-like microfossil that emerged at the end of an ice age some 635 million years ago.

Pioneering research unravels hidden origins of Eastern Asia's 'land of milk and honey'

Wed, 01/27/2021 - 22:25
A study has revealed for the first time the ancient origins of one of the world's most important ecosystems by unlocking the mechanism which determined the evolution of its mountains and how they shaped the weather there as well as its flora and fauna.

Up-trending farming and landscape disruptions threaten Paris climate agreement goals

Wed, 01/27/2021 - 21:01
Earth system science researchers conducted an analysis of greenhouse gas emissions from agriculture and land use since 1961, finding some opportunities for mitigation as well as areas where curtailment will require sacrifices.

Diving into Devonian seas: Ancient marine faunas unlock secrets of warming oceans

Wed, 01/27/2021 - 21:01
Paleontologists use ancient marine faunas to test long-term changes in our warming oceans.

Key switchgrass genes identified, which could mean better biofuels ahead

Wed, 01/27/2021 - 19:24
Biologists believe they are one step closer to a long-held goal of making a cheap, widely available plant a source for energy and fuel, meaning one of the next big weapons in the battle against climate change may be able to trace its roots to the side of a Texas highway.

Carbon: Getting to net zero -- and even net negative -- is surprisingly feasible, and affordable

Wed, 01/27/2021 - 19:24
Reaching zero net emissions of carbon dioxide from energy and industry by 2050 can be accomplished by rebuilding U.S. energy infrastructure to run primarily on renewable energy, at a net cost of about $1 per person per day, according to new research.

More than just CO2: It's time to tackle short-lived climate-forcing pollutants

Wed, 01/27/2021 - 19:23
Climate change mitigation is about more than just CO2. So-called 'short-lived climate-forcing pollutants' such as soot, methane, and tropospheric ozone all have harmful effects. Climate policy should be guided by a clearer understanding of their differentiated impacts.

New study identifies bird species that could spread ticks and Lyme disease

Wed, 01/27/2021 - 16:32
A new study used machine learning to identify bird species with the potential to transmit the Lyme disease bacterium (Borrelia burgdorferi) to feeding ticks. The team developed a model that identified birds known to spread Lyme disease with 80% accuracy and flagged 21 new species that should be prioritized for surveillance.
