In estimations of ocean heat content -- important when assessing and predicting the effects of climate change -- calculations have often presented the rate of warming as a gradual rise from the mid-20...
The rate of sea level rise in the 20th century along much of the U.S. Atlantic coast was the fastest in 2,000 years, and southern New Jersey had the fastest rates, according to a Rutgers Universi...
Severe declines in megafauna worldwide illuminate the role of top predators in ecosystem structure. In the Antarctic, the Krill Surplus Hypothesis posits that the killing of more than 2 million larg...
Culture in Catalonia and, specifically, science had an important rebirth in the second half of the 19th century. But, due to the lack of State support, development of earth physical sciences in Catalo...
Desert dust perturbs climate by directly and indirectly interacting with incoming solar and outgoing long wave radiation, thereby changing precipitation and temperature, in addition to modifying ocean...
Tornado activity is associated with extreme convective weather which can cause extended damage and even in some cases the loss of life. The complex inland terrain of Greece along with the Ionian Sea a...
Some of the worst droughts to hit North Africa in the last 900 years have occurred recently—in the late 20th century—according to an analysis of tree rings that has provided the most lengthy and detai...
This paper presents a new reconstruction of the 20th century global hydrography using fully coupled water balance and transport model in a flexible modeling framework. The modeling framework allows a ...
A strengthening of the equatorward temperature gradient in the upper troposphere/lower stratosphere (UTLS), at subtropics and midlatitudes, is consistently reproduced in several modelling studies of t...
Hydrology is a geoscience, whose scientific basis lies mainly in physics, but also in chemistry and biology of the endless cycle of water. This so called hydrological cycle is a global geophysical p...
The development of non-seismic aspects of solid Earth geophysics in Finland is described along five major lines: geomagnetic research at observatories, applied geophysics to assist mineral prospectin...
The Earth was considered to be a sphere until the end of the 17th century. Only then, the concept of an Earth flattened at the poles was beginning to gain support among scientists. A powerful influe...
A 137 m ice core drilled in 1999 from Eastern Bolivian Andes at the summit of Nevado Illimani (16º 37' S, 67º 46' W, 6350 m asl) was analyzed at high temporal resolution, allowing a characte...
