“It is possible that the Arctic Ocean is more sensitive to greenhouse gases than previously thought,” said one of the study’s authors. New research published Wednesday revealed the Arctic Ocean has been warming for decades longer than scientists previously understood, raising fresh concerns as the polar region faces the growing threat of a total loss of […]
A University of Alaska Fairbanks scientist has discovered a method for detecting and better defining meteorite impact sites that have long lost their tell-tale craters. The discovery could further the study of not only Earth’s geology but also that of other bodies in our solar system. The key, according to work by associate research professor Gunther […]
Genes evolved under intense poaching pressure In regions of Africa wracked by heavy poaching, scientists have observed an increasing number of African elephants without their iconic white tusks, prized in the multibillion-dollar wildlife black market. But there has been no direct evidence indicating how this was happening or why this trait was occurring exclusively in […]
New research shines light on poorly understood processes Geoscientist Michael Rawlins of the University of Massachusetts Amherst is improving the understanding of the Arctic’s carbon cycle — the way carbon is transferred among the land, ocean and atmosphere. To better understand future trends in atmospheric carbon dioxide and climate change, a fuller picture of how carbon cycles […]
