A new study says that global warming has measurably worsened the ongoing California drought. While scientists largely agree that natural weather variations have caused a lack of rain, an emerging consensus says that rising temperatures may be making things worse by driving moisture from plants and soil into the air.
When trying to explain the potential effects of climate change on plants, fish and wildlife, scientists usually resort to language that fails to convey the impact of warming. Now, a study by Penn State's College of Agricultural Sciences fisheries researchers clearly explains the impact of projected warming waters on wild brook trout in the eastern U.S. for fishermen.
In the Arctic, enhanced vegetation growth amplifies global warming. On the Tibetan Plateau, however, the situation is the reverse.
Climate change is one of the most critical issues of the 21st Century, presenting a major intellectual challenge to both the natural and social sciences. While there has been significant progress in natural science understanding of climate change, social science analyses have not been as fully developed. Edited by Riley E. Dunlap and Robert J. Brulle, the forthcoming book, Climate Change and Society: Sociological Perspectives, breaks new theoretical and empirical ground by presenting climate change as a thoroughly social phenomenon, embedded in behaviors, institutions, and cultural practices.
China's carbon emissions have been substantially over estimated by international agencies for more than 10 years, according to research co-led by the University of East Anglia.
Old dogs can teach humans new things about evolution. In Nature Communications a new study of North American dog fossils as old as 40 million years suggests that the evolutionary path of whole groups of predators can be a direct consequence of climate change.
Stronger winds forecast as a result of climate change could impact on populations of wild animals, by affecting how well they can feed, a study of seabirds suggests.
The atmosphere is so unstable that a butterfly flapping its wings can, famously, change the course of weather patterns. The celebrated "butterfly effect" also means that the reliability of weather forecasts drops sharply beyond 10 days.
The expected impact of climate change on North American lizards is much worse than first thought. A team of biologists led by Arizona State University investigators has discovered that lizard embryos die when subjected to a temperature of 110 degrees Fahrenheit even for a few minutes.
An international team of researchers found an 1800 year-long cooling trend in the surface layer of the Earth's oceans, and that volcanic eruptions were the likely cause of the cooling from 801 to 1800 AD. The coolest temperatures were during the Little Ice Age - that was before man-made global warming erased the cooling trend in the 1800s.
