Observations of stellar visibility by citizen scientists accurately measure the brightness of the night sky
A team of researchers from Germany, Italy, and the USA have shown that observations of stellar visibility by citizen scientists accurately measure the brightness of the night sky. The researchers published their results Thursday ...
Deserts 'greening' from rising CO2
Increased levels of carbon dioxide (CO2) have helped boost green foliage across the world's arid regions over the past 30 years through a process called CO2 fertilisation, according to CSIRO research.
New study explains surprising acceleration of Greenland's inland ice
Surface meltwater draining through cracks in an ice sheet can warm the sheet from the inside, softening the ice and letting it flow faster, according to a new study by scientists at the Cooperative Institute ...
Climate models make too hot forecasts of global warming
Data from NASA's Terra satellite shows that when the climate warms, Earth's atmosphere is apparently more efficient at releasing energy to space than models used to forecast climate change have been programmed to "believe."
Huge iceberg breaks away from the Pine Island glacier in the Antarctic
On 8 July 2013 a huge area of the ice shelf broke away from the Pine Island glacier, the longest and fastest flowing glacier in the Antarctic, and is now floating in the Amundsen Sea in the form of a very ...
Greenland ice cap melting faster than ever
Satellite observations and a state-of-the art regional atmospheric model have independently confirmed that the Greenland ice sheet is loosing mass at an accelerating rate, reports a new study in Science.
Arctic ice cover hits historic low: scientists
The area covered by Arctic sea ice reached its lowest point this week since the start of satellite observations in 1972, German researchers announced on Saturday.
Chasing the black holes of the ocean
According to researchers from ETH Zurich and the University of Miami, some of the largest ocean eddies on Earth are mathematically equivalent to the mysterious black holes of space. These eddies are so tightly ...
GOCE satellite achieves drag-free perfection (w/Videos)
(PhysOrg.com) -- ESA's gravity mission GOCE has achieved a first in the history of satellite technology. The sophisticated electric propulsion system has shown that it is able to keep the satellite completely ...
'Missing' heat may affect future climate change
Current observational tools cannot account for roughly half of the heat that is believed to have built up on Earth in recent years, according to a "Perspectives" article in this week's issue of Science. Scientists at the ...
NOAA study suggests aerosols might be inhibiting global warming
Satellites see unprecedented Greenland ice sheet surface melt
For several days this month, Greenland's surface ice cover melted over a larger area than at any time in more than 30 years of satellite observations. Nearly the entire ice cover of Greenland, from its thin, ...
Arctic sea ice hits record low
Arctic sea ice has reached its lowest winter point since satellite observations began in the late 1970s, raising concerns about faster ice melt and rising seas due to global warming, US officials said Thursday.
Why Antarctic sea ice cover has increased under the effects of climate change
The first direct evidence that marked changes to Antarctic sea ice drift have occurred over the last 20 years, in response to changing winds, is published this week in the journal Nature Geoscience. Scient ...
