Statistically, humanity is almost certainly responsible for global warming

The world is getting warmer, with 13 out of the 15 warmest years on record occurring in the current century. But just how sure are we that humanity's burning of oil and coal is the key factor in the temperature increase? A new project, led by researchers at the Potsdam Institute for Climate Impact Research, has answered that very question, working to estimate the likelihood of those temperature trends occurring naturally.

Breaking down humanity's contribution to climate change

Over the past 100 years, global temperatures have risen by an average amount of 0.8° C (1.4° F), which according to the Intergovernmental Panel on Climate Change (IPCC), is due largely to humanity's release of pollutants into the atmosphere. Now an international team of researchers has analyzed almost 40 years worth of data in order to quantify exactly what fraction of the change can be attributed to mankind based on events and trends in different regions.

Arctic winter observations show higher-than-expected methane emissions

A new study led by researchers from NASA's Jet Propulsion Laboratory (JPL) and San Diego State University (SDSU) has examined the amount of methane gas escaping from the Arctic – a key component of global warming. The results go against conventional theory, finding that a much larger amount of the gas escapes during the Arctic winter than previously thought.

Sucking CO2 out of the atmosphere to create carbon nanofibers

Carbon nanofibers hold tremendous potential. They may one day be put to use in tougher bulletproof vests, artificial muscles or rebuilding damaged hearts, just to name a few possibilities. But could the greatest gift these little wonders offer humanity be not what they bring into the world but what they take out of it? Scientists have developed a technique that could take the mounting carbon dioxide in our atmosphere and transform it into carbon nanofibers, resulting in raw materials for use in anything from sports gear to commercial airliners.

The Pilgreens embark on electric tuk-tuk odyssey to promote green mobility

Three French students will travel from Bangkok, Thailand to Toulouse, France on an electric tuk-tuk in an effort to demonstrate that electric power will be sufficient for our future mobility needs. They plan to cover 20,000 km (12,427 mi) through 16 countries in 120 days on their modified three wheeler relying on two giant batteries, a solar panel and the generosity of strangers.

Study suggests volcanic eruptions behind pause in climate change

Over the last few years, many possible explanations have been bandied about for the so-called pause in climate change, a plateau in global surface air temperatures that is out of step with rising greenhouse gas concentrations. But now an international research effort is laying responsibility at the feet of volcanic eruptions, whose particles it has found reflect twice as much solar radiation as previously believed, serving to temporarily cool the planet in the face of rising CO2 emissions.
