Carbon 'budget' may be bigger than thought: study

An ambitious goal to limit global warming to 1.5 degrees Celsius is still within reach, said researchers Monday who calculated humanity may have a larger allowable "budget" for burning carbon than previously thought.

Six-fold jump in polar ice loss lifts global oceans

Greenland and Antarctica are shedding six times more ice than during the 1990s, driving sea level rise that could see annual flooding by 2100 in regions home today to some 400 million people, scientists have warned.

New route to carbon-neutral fuels from carbon dioxide discovered

If the idea of flying on battery-powered commercial jets makes you nervous, you can relax a little. Researchers have discovered a practical starting point for converting carbon dioxide into sustainable liquid fuels, including ...

Ion drive space engine used on aircraft for first time

Imagine an aircraft engine that has no moving parts, produces no harmful exhaust and makes no noise. That's what researchers at the Massachusetts Institute of Technology (MIT) in the US have created by adapting a technology ...

New studies sully reputation of biomass as clean and green

Simpson Tacoma Kraft would seem like one of the greener power plants. It boils water by burning sawdust, bark and wood shavings from saw mills and pulp mills, funneling the resulting high-pressure steam into a turbine to ...

Nanodiamonds as photocatalysts

Climate change is in full swing and will continue unabated as long as CO2 emissions continue. One possible solution is to return CO2 to the energy cycle: CO2 could be processed with water into methanol, a fuel that can be ...

Large differences in the climate impact of biofuels

When biomass is combusted the carbon that once was bound in the growing tree is released into the atmosphere. For this reason, bioenergy is often considered carbon dioxide neutral. Research at the University of Gothenburg, ...
