Human well-being will be severely jeopardized by negative trends in some types of environmental harm, such as a changing climate, deforestation, loss of access to fresh water, species extinctions and human population growth, ...
Every year, humans advance climate change and global warming - and quite likely our own eventual extinction - by injecting about 30 billion tonnes of carbon dioxide into the atmosphere.
Using up all known fossil fuel reserves would render Earth even more unliveable than scientists had previously projected, researchers said on Monday.
A new study from University of Michigan researchers challenges the widely held assumption that biofuels such as ethanol and biodiesel are inherently carbon neutral.
One of the most worrisome aspects of climate change is the role played by positive feedback mechanisms. In addition to global temperatures rising because of increased carbon dioxide and greenhouse gas emissions, there is ...
Methane emissions caused by human activity may have a bigger impact on global warming than previously thought, scientists have found.
Rising temperatures could accelerate climate change by reducing the amount of carbon dioxide stored in ponds and increasing the methane they release, new research shows.
Over a quarter of the world's land could become significantly drier if global warming reaches 2C - according to new research from an international team including the University of East Anglia.
Global warming is edging perilously close to out-of-control, according to a growing number of scientific reports from round the planet, a leading science writer has warned.
