Voices: Defending science: The link between creationism and climate change

What do creationists and climate change deniers have in common? Over the past few years, this riddle has been on our minds a lot at the National Center for Science Education, a nonprofit that has fought for more than a quarter-century to defend the teaching of evolution in the public schools. Now, we’re expanding to defend the teaching of climate change — and with it, science in general.

Mobile mapping with lidar hits the road

About a decade ago, Light Detection and Ranging technology, also known as lidar, burst onto the geoscience scene. The tool was quickly adopted by researchers, from archaeologists and geomorphologists to seismologists and atmospheric scientists.

By mounting lasers and detection and positioning instruments on an airplane or satellite, researchers could map everything from Mayan ruins lost beneath thick jungle canopies to erosion along shorelines to the structure of particulate plumes emitted from power plants to the topography of entire countries.

Managing the seismic risk posed by wastewater disposal

From an earthquake perspective, 2011 was a remarkable year. While the devastation accompanying the magnitude-9.0 Tohoku earthquake that occurred off the coast of Japan on March 11 still captures attention worldwide, the relatively stable interior of the U.S. was struck by a somewhat surprising number of small-to-moderate earthquakes that were widely felt. Most of these were natural events, the types of earthquakes that occur from time to time in all intraplate regions.

U.S. Navy navigates a sea change in the Arctic

Arctic sea ice is already significantly declining in both extent and thickness, and impacts of the decline are evident. New shipping lanes in the Northwest Passage have been passable for ship traffic during summer months for the last two years, and an increasingly accessible Arctic is attracting increased interest. Shipping companies, entrepreneurs, scientists and tourists, however, are not the only ones looking north; militaries around the world, including the U.S. Navy, also have an interest. To that end, the Navy has created a task force and employed a corps of geoscientists to help develop a roadmap for expected future Arctic operations.

IceGoat: The next generation

One source of young talent to carry the military’s proposals and technologies into the future will come from the U.S. Naval Academy in Annapolis, Md., where Lt. Cmdr. John Woods, an oceanography professor, specializes in sea-ice studies. Woods recently launched a polar science program, supported by the academy’s STEM Office, which he hopes will convey to students an understanding of sea-ice dynamics — how ice is thinning and what’s causing it to thin.

Down to Earth With: Volcanologist Stephen Sparks

From the Caribbean to Iceland to the Andes, volcanologist Stephen Sparks has spent a lifetime studying volcanoes. As a professor of geology at the University of Bristol in England for more than 20 years, Sparks has devoted much of his time to figuring out where the next eruption will occur and how to respond to it. His latest effort is a project that will connect experts and technology in a global network to improve volcanic risk assessment.

Blogging On EARTH: Wisconsin's microquake mystery

On the list of earthquake-prone states, Wisconsin does not rank highly. Yes, occasionally, America’s Dairyland is subjected to light rumbles emanating from its neighbor to the south, Illinois. But Wisconsin is hardly where you’d expect to find much excitement, let alone fear, over the possibility of homegrown seismic activity. And yet, that's exactly what happened a few weeks ago, when hundreds of people in Clintonville, Wis. began dialing 911 with reports that their homes were being inexplicably shaken overnight by terrifying booms.

Travels in Geology: Chile: Exploring the archaeology, volcanoes and hot springs of the northern Atacama Desert

Mention the Atacama Desert and many people likely imagine an ocean of sand where rain never falls and life faces insurmountably hostile conditions. This is, after all, where scientists go to study Mars. Although some regions of the Atacama are indeed stark and barren, the northern section of this vast desert, which stretches approximately 965 kilometers along the western edge of Chile, contains diverse ecosystems, a rich archaeological history and, of course, intriguing geologic features.
