Running into the brick wall of Creationism again

I had recently moved to a new community and begun a new job. One night I was dining with some potential new friends. Upon learning that I am both a Christian and a passionate student of geology, one of my dinner mates proclaimed, “So, I suppose you believe in evolution, right? Well, I need to let you know that I HATE evolution.” I somehow managed to keep my cool. “And exactly why do you hate evolution?” I queried. “My minister has taught us that it is false Christian teaching,” she retorted. By that time, I could not hold myself back.

Oil barrel politics

As a new president and Congress entered office in January, current events continue to keep energy in the forefront of national concern. Volatile prices, resource depletion, climate change and national security impacts of energy trade have become a part of daily news and policy discussion. Americans will be watching the new policymakers to see how they respond to energy concerns. How they treat energy research and development — particularly the amount of funds dedicated to R&D, and the portion of that R&D that is allocated through earmarks — will be telling.

Earth: The movie (not the magazine)

Blogging on EARTH (the magazine)

Earth Day is over. But you don’t have to wait until next year to celebrate the planet. Disney’s new movie “Earth,” which opened Apr. 22, offers some spectacular views of the planet and its inhabitants.

Seal missing link found in the Arctic

A newly discovered web-footed mammal may be a “missing link” between land-based and marine pinnipeds, a group that includes seals, walruses and sea lions. The find, occurring on the 150th anniversary of Charles Darwin’s "On the Origin of Species," may shed new light on the land-to-sea animal evolutionary theory.

Benchmarks: Nuclear explosion at Chernobyl

April 26, 1986

A rusting Ferris wheel dominates the skyline of Prypiat, Ukraine’s ghost town. A few kilometers away, within a massive concrete structure called the Sarcophagus, are the remnants of the worst nuclear disaster in history: the ruins of the Chernobyl Nuclear Power Plant’s reactor number four — and about 200 tons of highly radioactive material.

Travels in Geology: Exploring Lake Baikal, the Sacred Sea

Deepest. Oldest. Most biologically diverse. Siberia’s superlative-laden Lake Baikal is one of the planet’s great geological treasures. Located 4,200 kilometers east of Moscow and 2,100 kilometers west of Vladivostok, the lake known locally as the Sacred Sea is like no other.

Mining for iron oxides in coal mine sludge

The billions of tons of coal that miners extracted from Pennsylvania’s ground over the past two centuries have long gone up in smoke, but their legacy lives on in the state’s rivers and waterways. Nasty discharge — often with sky-high metal concentrations — from thousands of abandoned coal mines has been polluting Pennsylvania’s streams and groundwater.

Geoscientists Without Borders: Geologists Lend a Hand

Craig Beasley’s one-year term as president of the Society for Exploration Geophysicists had a challenging start. After about two months in office, a magnitude-9-plus earthquake struck off the coast of Sumatra on Dec. 26, 2004, triggering a powerful tsunami that killed more than 225,000 people and left hundreds of thousands homeless.

SEG members wanted to help, but did not know how to contribute their expertise. “I could encourage members to donate money and time, but how does that distinguish a contribution from SEG from what people would normally do?” Beasley says.

Iron fertilization foiled by "shrimp"

The argument over whether ocean iron fertilization is a good way to sequester carbon dioxide may be coming to an end. Last month, a group of researchers seeded 300 square kilometers of the southwestern Atlantic Ocean with six metric tons of dissolved iron. Just as researchers hoped, algae bloomed, doubling in biomass within the first two weeks of the fertilization. But then, an unexpected guest showed up: tiny shrimp-like crustaceans that dined on the algae.
