Cloud mystery solved: Global temperatures to rise at least 4C by 2100
Global average temperatures will rise at least 4°C by 2100 and potentially more than 8°C by 2200 if carbon dioxide emissions are not reduced according to new research published in Nature. Scientists found global climat ...
Plugging the hole in Hawking's black hole theory
(Phys.org) —Recently physicists have been poking holes again in Stephen Hawking's black hole theory – including Hawking himself. For decades physicists across the globe have been trying to figure out ...
Human cause of global warming is near certainty, UN reports
Global warming is unequivocal, human influence has been the dominant cause since the mid-20th century, and atmospheric concentrations of greenhouse gases, already at levels not seen in at least 800,000 years, ...
Long-term warming likely to be significant despite recent slowdown
A new NASA study shows Earth's climate likely will continue to warm during this century on track with previous estimates, despite the recent slowdown in the rate of global warming.
Physicists propose a device to capture energy from Earth's infrared emissions to outer space
(Phys.org) —When the sun sets on a remote desert outpost and solar panels shut down, what energy source will provide power through the night? A battery, perhaps, or an old diesel generator? Perhaps something ...
Researchers report on new catalyst to convert greenhouse gases into chemicals
(Phys.org) —A team of researchers at the University of Delaware has developed a highly selective catalyst capable of electrochemically converting carbon dioxide—a greenhouse gas—to carbon monoxide with ...
Experts say nuclear power needed to slow warming
Some of the world's top climate scientists say wind and solar energy won't be enough to head off extreme global warming, and they're asking environmentalists to support the development of safer nuclear power ...
Sun's energy influences 1,000 years of natural climate variability in North Atlantic
Changes in the sun's energy output may have led to marked natural climate change in Europe over the last 1000 years, according to researchers at Cardiff University.
UN scientists see grim future if no climate action
UN scientists are set to deliver their darkest report yet on the impacts of climate change, pointing to a future stalked by floods, drought, conflict and economic damage if carbon emissions go untamed.
Black hole birth captured by cosmic voyeurs
Intelligent telescopes designed by Los Alamos National Laboratory got a front row seat recently for an unusual birth.
Population growth rate bodes decline in living standards
In 1972 a group of scientists, known collectively as the Club of Rome, constructed a detailed mathematical model to test whether population growth and economic development could continue indefinitely and ...
'Hybrid' nuclear plants could make a dent in carbon emissions
Many efforts to smooth out the variability of renewable energy sources—such as wind and solar power—have focused on batteries, which could fill gaps lasting hours or days.
Acid raid, ozone depletion contributed to ancient extinction
Rain as acidic as undiluted lemon juice may have played a part in killing off plants and organisms around the world during the most severe mass extinction in Earth's history.
Meeting climate targets may require reducing meat and dairy consumption
Greenhouse gas emissions from food production may threaten the UN climate target of limiting global warming to 2 degrees Celsius, according to research at Chalmers University of Technology, Sweden.
