Beyond LEDs: Brighter, new energy-saving flat panel lights based on carbon nanotubes
Even as the 2014 Nobel Prize in Physics has enshrined light emitting diodes (LEDs) as the single most significant and disruptive energy-efficient lighting solution of today, scientists around the world continue ...
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 ...
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.
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 ...
Mysterious source of ozone-depleting chemical baffles NASA
A chemical used in dry cleaning and fire extinguishers may have been phased out in recent years but NASA said Wednesday that carbon tetrachloride (CCl4) is still being spewed into the atmosphere from an unknown ...
Satellite data shows livestock emitted more methane than oil and gas industry in 2004
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.
Cutting emissions pays for itself, research shows
Lower rates of asthma and other health problems are frequently cited as benefits of policies aimed at cutting carbon emissions from sources like power plants and vehicles, because these policies also lead ...
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.
Climate change not so global
(Phys.org) —Scientists are calling for a better understanding of regional climates, after research into New Zealand's glaciers has revealed climate change in the Northern Hemisphere does not directly affect ...
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.
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 ...
Obama mocks foes who brand climate change a 'liberal plot'
US President Barack Obama mocked Republicans who reject global warming as a "liberal plot," as he pumped up a crowd of environmental activists in Washington.
To address climate change, nothing substitutes for reducing CO2 emissions
The politically expedient way to mitigate climate change is essentially no way at all, according to a comprehensive new study by University of Chicago climatologist Raymond Pierrehumbert.
