Loss of ice in Antarctica caused by a warming ocean could raise global sea levels by three meters, research suggests.

Mathematicians and glaciologists have taken a first step toward understanding how glacier ice flowing off Greenland affects sea levels.

Not only is Greenland's melting ice sheet adding huge amounts of water to the oceans, it could also be unleashing 400,000 metric tons of phosphorus every year -- as much as the mighty Mississippi River releases into the Gulf of Mexico, according to a new study. Phosphorus is an essential nutrient that feeds plankton at the base of the ocean food web.

By examining how Earth restores equilibrium after periods of natural warming, a new study reinforces that long-term global temperature does not evolve chaotically but remains stable unless pushed by external factors. Large, sustained changes in global temperature, like those observed over the last century, cannot occur without drivers such as increased greenhouse gas concentrations. Estimates of natural climate cycles alone are insufficient to explain such changes.

Researchers have found that glacial erosion and melting ice caps both played a key role in driving the observed global increase in volcanic activity at the end of the last ice age.

One of the many dangers resulting from global warming is the melting of glaciers. To ascertain how this will affect sea levels in the future, it is important to know how glaciers behave.

There is a growing debate over the fate of the world's largest ice sheet, whose sudden melting is sending shockwaves throughout the geophysics community. Researchers contend that by studying other periods of global warming--namely, the Mid-Pliocene Warm Period (MPWP), which occurred approximately 3 million years ago, scientists can better understand the potential impact of today's warming trendings.

Hydrothermal activity along the mid-ocean ridge system suggests that the release of molten rock, or magma, in response to changes in sea level plays a significant role in the earth's climate.

Most of Europe has experienced strong summer warming over the course of the past several decades, accompanied by severe heat waves in 2003, 2010 and 2015. New research now puts the current warmth in a 2,100-year historical context using tree-ring information and historical documentary evidence to derive a new European summer temperature reconstruction.

Scientists plumbing the depths of the central equatorial Pacific Ocean have found ancient sediments suggesting that one proposed way to mitigate climate warming -- fertilizing the oceans with iron to produce more carbon-eating algae -- may not necessarily work as envisioned.

The species Amphilagus tomidai was recently discovered - an ancestor of the rabbit which lived in present-day Siberia during the Miocene, about 14 million years ago. The discovery of this mammal, belonging to a family which was thought to only exist in Europe, reveals that the two continents were presumably connected free of natural barriers due to the disappearance of the ancient Paratethys Sea. A study presents a new species, the Amphilagus tomidai, found in south-eastern Siberia (Russia) and dating back to the Middle Miocene, about 14 million years ago. The discovery of this mammal, an ancestor of the present-day rabbit, represents an important biogeographic link that confirms the widespread distribution of this group as well as the relationship between Asia and Europe during this period.
