Are we killing the world's oceans?

How will global warming affect ocean circulation and sea levels in the centuries to come? Are we destroying the world's coral reefs? Why are dead zones in the oceans on the rise? Can aquaculture be environmentally sustainable? And how are we all to blame for the collapse of...

Imaging pinpoints brain regions that 'see the future'

...he future in the abstract sense (e.g., that global warming is a concern for the future), but they cannot vividly envision themselves in a specific future scenario. "The same is true with very small children -- they don't remember particularly what happened last month and they can't really tell you much o...

Tundra disappearing at rapid rate

...y found that a rapid change in response to climate warming during the early mid 20th century was observed at all locations. Treeline advanced considerably—as much as 85 metres elevation—on warm, south-facing slopes and tree density increased significantly—as much as 65 per cent—on cooler, north-facing slopes...

Improved predictions of warming-induced extinctions sought

...ls for better forecasting of the effects of global warming on extinction rates. The researchers, led by Daniel B. Botkin, note that although current mathematical models indicate that many species could be at risk from global warming, surprisingly few species became extinct during the past 2.5 million years, ...

Global survey of lizards reveals greater abundance of animals on islands than on mainland ecosystems

...gnals an alarm for island populations in a rapidly warming world. It suggests that climate change may have devastating consequences for lizards and other animals that inhabit islands because their ecosystems are much more sensitive than those on the mainland to change.
