In Europe, most migratory fish species completing their cycle between the sea and the river are currently in danger. Although restoration programmes have been set up, the future distribution of these species may be modified because of climate change. At the Bordeaux Cemagref, scientists have developed biogeographical models to predict their distribution on the 2100 [...]

As polar bears adapt to a warming Arctic—a frozen seascape that cleaves earlier each spring—they may find relief in an unlikely source: snow goose eggs. New calculations show that changes in the timing of sea-ice breakup and of snow goose nesting near the western Hudson Bay could provide at least some polar bears with an [...]

MIT researchers have created a microbial ecosystem smaller than a stick of gum that sheds new light on the plankton-eat-plankton world at the bottom of the aquatic food chain.
The work, reported in the January print issue of American Naturalist, may lead to better predictions of marine microbes` global-scale influence on climate.
Through photosynthesis and uptake of [...]

Rocky Mountain ski areas face dramatic changes this century as the climate warms, including best-case scenarios of shortened ski seasons and higher snowlines and worst-case scenarios of bare base areas and winter rains, says a new Colorado study.
The study indicates snowlines — elevations below which seasonal snowpack will not develop — will continue to rise [...]

Increasing pressures from climate change will reach a tipping point in less than a decade triggering a significant decline in the health of the planet`s coral reef ecosystems according to the findings in an international report.
Released by the Global Coral Reef Monitoring Network and the International Coral Reef Initiative, international governmental and scientific partnerships, "Status [...]

Researchers have discovered that the ocean`s chemical makeup is less stable and more greatly affected by climate change than previously believed. Researchers report that during a time of climate change 13 million years ago the chemical makeup of the oceans changed dramatically. The researchers warn that the chemical composition of the ocean today could be [...]

Enormous cave bears, Ursus spelaeus, that once inhabited a large swathe of Europe, from Spain to the Urals, died out 27,800 years ago, around 13 millennia earlier than was previously believed, scientists have reported.
The new date coincides with a period of significant climate change, known as the Last Glacial Maximum, when a marked cooling in [...]
