Great Barrier Reef suffers through worst coral bleaching event on record

Scientists have warned that global warming is hurting Australia's Great Barrier Reef, but a new study has brought to light just how far along the damage might already be. An aerial survey of more than 500 coral reefs making up the system has revealed that almost all have suffered severe bleaching, with the researchers labeling it the worst mass bleaching event in the World Heritage Site's history.Read More

Cyberforests help scientists predict the effects of climate change

Considering that it takes hundreds of years for forests to grow, it can be difficult to assess how they'll be affected by climate change in the long term. To address that problem, researchers at Washington State University have created the world's first computer simulation capable of growing realistic forests, using the model to predict how things like frequent wildfires or drought might impact forests across North America.Read More

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.Read More

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.Read More

NASA's TIMED satellite identifies unexpected carbon dioxide trends

NASA has analyzed 14 years worth of data collected by its Thermosphere, Inonosphere, Mesosphere Energetics and Dynamics (TIMED) satellite, revealing a surprisingly fast increase in carbon dioxide levels in the upper atmosphere. The stats also reveal that the gas is more localized to the Northern Hemisphere than predicted by climate models.Read More

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.Read More
