Multiple, Intense, Abrupt Late Pleistocene Warming And Cooling: Implications For Understanding The Cause Of Global Climate Change

Guest essay by Dr. Don J. Easterbrook Dept. of Geology, Western Washington University, Bellingham, WA The results of oxygen isotope measurements from ice cores in the Greenland and Antarctic ice sheets several decades ago stunned the scientific world. Among the surprises from the cores was the recognition of multiple, late Pleistocene, extraordinarily abrupt, intense periods…

A link between climate, ice melt, and volcanic eruptions is found

When the ice melts, the Earth spews fire GEOMAR researchers discover a link between climate and volcanic eruptions It has long been known that volcanic activity can cause short-term variations in climate. Now, researchers at the GEOMAR Helmholtz Centre for Ocean Research Kiel (Germany), together with colleagues from Harvard University (Cambridge, Massachusetts, USA) have found…

Tornadoes make the earth move

From Indiana University Scientists detect seismic signals from tornado BLOOMINGTON, Ind. — An Indiana University geophysical experiment detected unusual seismic signals associated with tornadoes that struck regions across the Midwest last week — information that may have value for meteorologists studying the atmospheric activity that precedes tornado disasters. The experiment by IU researchers involves deployment…

Fundamental questions on Isostasy and Mean Sea-Level
