Geologic Column: By train or pipeline: That is the question

Transporting hazardous materials like oil on North America’s aging rail networks is risky. But pipelines are also risky. So what’s the best option, given that we must choose one?

Geologic Column: Beyond geology, field camps teach teamwork and inspire leadership

For undergraduate geology students, field camp is a rite of passage. And the importance of the experience, in terms of properly training and preparing geoscience students to become geoscience professionals, should not be underestimated.

Comment: Preparing for the death of Earth

About 5 billion years from now, Earth will meet its end in a fiery blaze as it is swallowed by the expanding sun. What happens between now and then, in large part, is up to us and our ability to prepare for the distant future.

Beyond rocks for jocks: Elevating geoscience education

Geoscientists can help alter the perception that some high school and college geoscience courses are less rigorous or demanding than other science courses.

Geologic Column: Riding the rails to Omaha with Rudolf Clausius

It was the German physicist Rudolf Clausius who, in 1850, dressed the Second Law in a tuxedo to show us that the pigpen was infinite. He said, “the entropy of the universe strives to reach a maximum.” That is a beautifully concise vision of our fate with the clear message that in the grand scheme of things, there is no escape. We’re all doomed and can do nothing about it. All order in the universe will degenerate into chaos.

Geomedia: California's climatic catastrophes detailed in "The West Without Water"

The 2013-2014 California drought has impacted everything from wildfires to food prices across the country. Politicians and the media called this the worst drought in California history, but scientists know that intense multiyear droughts are a regular feature of California’s climate. Fortunately, B. Lynn Ingram and Frances Malamud-Roam have put drought into context for everyone in their new history of California’s droughts and floods, “The West Without Water.”

Comment: The Oso landslide shows need for insurance and better planning

The deadly landslide that struck near Oso, Wash., in March killed more than 40 people and caused tens of millions of dollars in damage, most of which was not covered by insurance. The landslide was not a surprise to geologists. Could this disaster have been prevented — or can future disasters be prevented?

Geologic Column: Data security: freezers, floppies and flash drives

In the olden days, many of us protected our field notes, lab records and draft manuscripts by making multiple photocopies, storing them in different places, and perhaps keeping one in the freezer in case of fire. Today, much of our data is collected and stored electronically. What strategies do we use now to protect against catastropic loss?

Bare Earth Elements: Mars rocks wear manganese coats

Several rocks on the surface of Mars are coated with distinctive dark-colored surface layers enriched in manganese that, while sharing similarities with manganese-rich rock varnish found on Earth, do not appear to be varnish themselves based on differences in trace element levels, according to new research presented Wednesday by Nina Lanza of Los Alamos National Laboratory at the Lunar and Planetary Science Conference (LPSC) in The Woodlands, Texas.

IPCC: A failure in communicating the impact of new findings

In October, the Intergovernmental Panel on Climate Change (IPCC) released its Summary for Policymakers (SPM) to accompany the report of Working Group I on the physical science evidence for a warming planet. The SPM is designed to be the headline-grabbing addendum to the main report, written in plain language for nonscientists: policymakers, the media and the public. It is supposed to explain the findings of the unwieldy main report in a clear, concise manner. It fails to do so.
