Deep ocean current may slow due to climate change
(Phys.org) —Far beneath the surface of the ocean, deep currents act as conveyer belts, channeling heat, carbon, oxygen and nutrients around the globe.
Copper foam turns carbon dioxide into useful chemicals
A catalyst made from a foamy form of copper has vastly different electrochemical properties from catalysts made with smooth copper in reactions involving carbon dioxide, a new study shows. The research, by ...
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.
Drill core evidence adds credence to iron fertilization hypothesis regarding last ice age
Antarctic ice sheet is result of CO2 decrease, not continental breakup
Climate modelers from the University of New Hampshire have shown that the most likely explanation for the initiation of Antarctic glaciation during a major climate shift 34 million years ago was decreased carbon dioxide (CO2) ...
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 ...
The Goldilocks principle: New hypothesis explains Earth's continued habitability
Researchers from USC and Nanjing University in China have documented evidence suggesting that part of the reason that the Earth has become neither sweltering like Venus nor frigid like Mars lies with a built-in ...
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.
Field study shows why food quality will suffer with rising carbon dioxide
For the first time, a field test has demonstrated that elevated levels of carbon dioxide inhibit plants' assimilation of nitrate into proteins, indicating that the nutritional quality of food crops is at ...
Climate change increases risk of crop slowdown in next 20 years
The world faces a small but substantially increased risk over the next two decades of a major slowdown in the growth of global crop yields because of climate change, new research finds.
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.
Volcanoes helped offset man-made warming: study
Volcanoes spewing Sun-reflecting particles into the atmosphere have partly offset the effects of Man's carbon emissions over a 15-year period that has become a global-warming battleground, researchers said Sunday.
Spanish island to be fully powered by wind, water
The smallest and least known of Spain's Canary Islands, El Hierro, is making a splash by becoming the first island in the world fully energy self-sufficient through combined water and wind power.
