Resting in the Karakoram Range between northern Pakistan and western China, the Karakoram glaciers are stumping scientists. Unlike most mountain glaciers, the Karakoram glaciers, which account for 3 percent of the total ice-covered area in the world, excluding Greenland and Antarctica, are not shrinking. On the contrary, a team of French glaciologists has recently confirmed that these glaciers on average have remained stable or may have even grown slightly in recent years. Although all...

What are today's biggest unanswered questions in earth science? In the July issue of EARTH Magazine, experts from a variety of disciplines weigh in on what they consider to be the biggest unsolved mysteries across the geosciences and how they think we may solve them. Of course, in science, answering one question typically floods the field with new questions and thus new lines of investigation. For example, the discovery in the mid-19th century that carbon dioxide traps heat in Earth's...

The American Geosciences Institute has released Geoscience Currents 60, which examines female enrollments and degrees in the geosciences over time. In 2011, the Current concludes, female participation in U.S. geoscience degree programs remained generally steady. After decades of steady growth in the rate of female participation, there has been little change since 2005. Several interesting trends are also noted, including declines in doctorates awarded following economic downturns, and that...

AGI conducted a follow-up study to research conducted by Houlton (Geoscience Currents 45-48) in a Geoscience Currents series that examines the various pathways taken by undergraduate geoscience majors when deciding to concentrate in the Earth sciences. Conducted in late 2011, the new follow-up study featured in Geoscience Currents 57 utilizes data from 13 of the original 17 participants and discusses the similarities and differences between population groups in the context of their changing...

State Of Himalayan Glaciers Less Alarming Than Feared
2012-04-20 08:21:58

Ever since the false prognoses of the Intergovernmental Panel on Climate Change (IPCC), the Himalayan glaciers have been a focus of public and scientific debate. The gaps in our knowledge of glaciers in the Himalayan region have hindered accurate statements and prognoses. An international team of researchers headed by glaciologists from the University of Zurich and with the involvement of scientists from Geneva now outlines the current state of knowledge of glaciers in the Himalayas in a...

Today the U.S. National Research Council released a synthesis of reports from thousands of scientists in 60 countries who took part in the International Polar Year (IPY) 2007-08, the first in over 50 years to offer a benchmark for environmental conditions and new discoveries in the polar regions. University of Massachusetts Amherst geosciences researcher and expert in the paleoclimate of the Arctic, Julie Brigham-Grette, co-chaired the NRC report, "Lessons and Legacies of the IPY 2007-08"...

The April/May GSA Today science article is now online at www.geosociety.org/gsatoday/. In this issue, Simon Williams and colleagues from the Earthbyte Group of the School of Geosciences at the University of Sydney present GPlates, a powerful new method for analyzing geological and geophysical data sets within the context of tectonic reconstructions. GPlates is part of a new generation of plate reconstruction software that incorporates functionality familiar from GIS software with the added...

Image 1 - Global Permafrost Zones Shown In High-res Google Earth Images

Thawing permafrost will have far-reaching ramifications for populated areas, infrastructure and ecosystems. A geographer from the University of Zurich reveals where it is important to confront the issue based on new permafrost maps -- the most precise global maps around. They depict the global distribution of permafrost in high-resolution images and are available on Google Earth. Unstable cable-car and electricity pylons and rock fall — Alpine countries like Switzerland have already...

Most research initiatives aim to discover more knowledge. The International Polar Year (IPY) went even further; it created more discoverers. That is what Canadian Arctic researcher David Hik will tell this week's meeting of the American Association for the Advancement of Science (AAAS) in Vancouver. "For the first time in the 130-year history of international polar years, people living in polar regions were not just objects of study – they led studies," said Hik. "This was the...

Environmental Science
2014-01-12 00:00:00

Environmental science is a science that contains a wide range of scientific disciplines. These disciplines are grouped together based on the natural environment which they encompass and interact with. These sciences include physical, chemical, and biological components. Environmental science provides an interdisciplinary approach to the study of the environmental systems. The most common way environmental science is studied is through the work of one individual or small team drawing on the...

Earth science (or geoscience) is the science of the planet Earth. Earth science can be broken down into four major disciplines, which are: geography, geology, geophysics, and geodesy. These disciplines use physics, chemistry, biology, chronology and mathematics to arrive to a greater understanding of the principal areas of the Earth system. Since Earth is the only known life-bearing planet, Earth science is solely dedicated to the geophysical makeup of our own planet. One discipline,...

  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
