There is no mint that can take the edge off sulfurous emissions from volcanoes, but researchers can use remote sensing to better understand volcanic breathing.
Volcanoes erupt, they spew ash, their scarred flanks sometimes run with both lava and landslides. But only occasionally. A less dramatic but important process is continuous gas emissions from volcanoes; in other words, as they exhale. A number of volcanoes around the world continuously exhale water vapor laced with heavy metals, carbon dioxide, hydrogen sulfide and sulfur dioxide, among many other gases. Of these, sulfur dioxide is the easiest to detect from space.
The 2011 Fukushima catastrophe is an ongoing disaster whose end only gets more remote as time passes. The government is desperate to get evacuees back into their homes for the 2020 Tokyo Olympics, but the problems on the ground, and in the breached reactor vessels, are only getting more serious and costly, as unbelievable volumes of radiation contaminate land, air and ocean.
With their measurements and samples, nearly 3,500 schoolchildren have assisted a research study on lakes and global warming, now published in an academic journal. The results show that water temperatures generally remain low despite the air becoming warmer. This helps to curb the outflow of greenhouse gases.
Conservationists working to safeguard tropical forests often assume that old growth forests containing great stores of carbon also hold high biodiversity, but a new study finds that the relationship may not be as strong as once thought, according to a group of researchers with contributions from WCS (Wildlife Conservation Society) and other organizations.
Tropical forests are exceptionally rich in both carbon and biodiversity, but the study recently published in the journal Scientific Reports indicates that, within the tropics, tree diversity and forest carbon do not necessarily correlate, and that there is no detectable relationship between the two factors across a region, a scale relevant for conservation planning and the establishment of protected areas. For instance, in Central Africa, some areas that are dominated by one or a few tree species are high in carbon density, whereas some forests with many more tree species have a lower carbon density.
Growing sustainable energy crops without increasing greenhouse gas emissions, may be possible on seasonally wet, environmentally sensitive landscapes, according to researchers who conducted a study on Conservation Reserve Program (CRP) land.
Debasish Saha, postdoctoral scholar in plant sciences, Penn State College of Agricultural Sciences, and colleagues measured the amount of nitrous oxide, a potent greenhouse gas, emanating from plots of biofuels-producing switchgrass — a native perennial grass — and miscanthus — a non-native grass species — growing in an experimental area in eastern central Pennsylvania and compared it to emissions from adjacent, undisturbed CRP acres. The experiment took place in a long-term monitoring site managed by the U.S. Department of Agriculture's Agricultural Research Service.
For the past eight years, Operation IceBridge, a NASA mission that conducts aerial surveys of polar ice, has produced unprecedented three-dimensional views of Arctic and Antarctic ice sheets, providing scientists with valuable data on how polar ice is changing in a warming world. Now, for the first time, the campaign will expand its reach to explore the Arctic’s Eurasian Basin through two research flights based out of Svalbard, a Norwegian archipelago in the northern Atlantic Ocean.
Temporary episodes of dizziness or light-headedness when standing could reduce blood flow to the brain with lasting impacts.
The giant panda’s graphic pattern has stumped biologists for years … now they have an answer.
Defined as the loss of memory due to brain injury, shock, fatigue, repression or illness, amnesia can be short- or long-term, full or partial. Renowned expert in the cognitive neuroscience of memory, York Research Chair Shayna Rosenbaum, a professor of psychology in the Faculty of Health, has spent her professional life investigating, among other things, the mystery of amnesia.
Ocean acidification is spreading rapidly in the western Arctic Ocean in both area and depth, potentially affecting shellfish, other marine species in the food web, and communities that depend on these resources, according to new research published in Nature Climate Change by NOAA, Chinese marine scientists and other partners.
