Direct evidence for a positive feedback in climate change
A new study has confirmed the existence of a positive feedback operating in climate change whereby warming itself may amplify a rise in greenhouse gases resulting in additional warming.
Canada revises upward CO2 emission data since 1990
Canada revised its greenhouse gas emission data from 1990 to 2013 in a report Friday, showing it had higher carbon dioxide discharges each year, and a doubling of emissions from its oil sands.
New material could boost batteries' power, help power plants
You're going to have to think very small to understand something that has the potential to be very big.
Increased levels of radon in Pennsylvania homes correspond to onset of fracking
Johns Hopkins Bloomberg School of Public Health researchers say that levels of radon in Pennsylvania homes - where 42 percent of readings surpass what the U.S. government considers safe - have been on the ...
Rocky planets may orbit many double stars
Luke Skywalker's home in "Star Wars" is the desert planet Tatooine, with twin sunsets because it orbits two stars. So far, only uninhabitable gas-giant planets have been identified circling such binary stars, ...
Oklahoma geology group links earthquakes to oil waste wells
The Oklahoma Geological Survey said Tuesday it is "very likely" that most of the state's recent earthquakes were triggered by the subsurface injection of wastewater from oil and natural gas drilling operations.
Converting food waste into solid fuels, biodiesel and other products
The Food and Agriculture Organization of the United Nations estimates that "a third of all the food produced in the world is never consumed," totaling about 1.3 billion tons of waste a year. The United States ...
More than a million stars are forming in a mysterious dusty gas cloud in a nearby galaxy
More than a million young stars are forming in a hot, dusty cloud of molecular gases in a tiny galaxy near our own, an international team of astronomers has discovered.
Using scientific methods to evaluate trade-offs of hydraulic fracturing
In Colorado, drilling for oil and natural gas using hydraulic fracturing, sometimes referred to as fracking, is big business. But, questions about its impact on the air and water are far from settled.
Speed with which temperatures change will continue to increase over next several decades, study shows
An analysis of changes to the climate that occur over several decades suggests that these changes are happening faster than historical levels and are starting to speed up. The Earth is now entering a period ...
Electricity from biomass with carbon capture could make western US carbon-negative
Generating electricity from biomass, such as urban waste and sustainably-sourced forest and crop residues, is one strategy for reducing greenhouse gas emissions, because it is carbon-neutral: it produces ...
Astronomers catch multiple-star system in first stages of formation
For the first time, astronomers have caught a multiple-star system in the beginning stages of its formation, and their direct observations of this process give strong support to one of several suggested pathways ...
Hubble discovers that Milky Way core drives wind at 2 million miles per hour
(Phys.org)—At a time when our earliest human ancestors had recently mastered walking upright, the heart of our Milky Way galaxy underwent a titanic eruption, driving gases and other material outward at ...
Study explains why galaxies don't churn out as many stars as they should
A handful of new stars are born each year in the Milky Way, while many more blink on across the universe. But astronomers have observed that galaxies should be churning out millions more stars, based on the ...
