A group of scientists have proposed a new framework to account more accurately for the effects of aerosols on precipitation in climate models.

A Spanish research study has revealed, for the first time, that now only the Pyrenees has active glaciers. Furthermore, the steady increase in temperature, a total of 0.9°C since 1890, indicates that Pyrenean glaciers will disappear before 2050, according to experts.

For instance, glaciation periods typically ended suddenly. About 34 million years ago the Earth’s long lasting tropical state in which most recent life forms evolved, shifted abruptly and irreversibly to a cooler state with ice caps. This shift is known as the "Greenhouse-Icehouse-Transition".

Scientists report that sea level rise from greenhouse-induced warming of the Greenland ice sheet could be double or triple current estimates over the next century.

Similar conditions can be found in Antarctica's McMurdo Dry Valleys. Rather than being a dead planet, the new data are consistent with dynamic climate changes on Mars.

Since the 1970s the winter storm track in the western US has been shifting north, particularly in the late winter. As a result, fewer winter storms bring rain and snow to Southern California, Arizona, Nevada, Utah, western Colorado and western New Mexico.

The ice edge is a biologically very active zone, in which algae increasingly grow, die , sink to the ground and serve as nutrients. If the ice edge shifts, it leads to changes in the availability of nutrients in the AWI-Hausgarten. What this year's thick ice cover brings about and whether the small and bigger animals of the deep sea are affected will be shown by the upcoming analyses in Bremerhaven as well as expeditions during the next years.
