Geotimes is a free electronic newsfeed for the geoscience community. Originally launched as GeoSpectrum, a newsletter of the American Geosciences Institute in 1995, Geotimes has been reborn as the go-to source of information on AGI's 52 Member Societies. The American Geosciences Institute coordinates and edits Geotimes, but it is the result of contributed materials from societies, geoscience organizations and others in the community.

EARTH: Geo-Travels: Exploring Colorado's Peaks and Dunes

Majestic snow-capped "fourteeners," alpine meadows carpeted in wildflowers, pristine mountain lakes. These are the images most people associate with Colorado. But charming mountain terrain is not the only attraction the Centennial State has to offer the geotraveler. One of Colorado's lesser-known geologic marvels is a vast field of sand dunes - the tallest in North America - a site sure to thrill anyone.

Our Ever-Changing Earth - The 2011 Earth Science Week Theme

The American Geological Institute (AGI) is pleased to announce the theme of Earth Science Week 2011 will be "Our Ever-Changing Earth." This year's event will engage the public in actively learning about the varied and interconnected natural processes that shape our planet over time.

YES Network becomes AGI's First International Associate

The American Geological Institute (AGI) is pleased to announce that the YES Network, a professional global network for the support of early-career professionals and students in the geosciences, is the first International Associate of the AGI Federation.

EARTH: How Dinosaurs Arose

Ask your kid what happened to the dinosaurs, and he or she will likely tell you that an asteroid killed them all. But ask how dinosaurs rose to prominence and you'll likely get a blank stare. Even many paleontologists may have little to say about the subject. But now, as EARTH explores in a feature in the February issue, new fossil discoveries are revealing the backstory of the rise of dinosaurs.

EARTH: Finding New Oil and Gas Frontiers

Where to next in the search for oil and gas? EARTH examines several possible new frontiers - including the Arctic, the Falkland Islands, the Levant, Trinidad and Tobago and Sudan - where oil and gas exploration are starting to take hold. One of those places, Sudan, is in the news for other reasons: South Sudan voted yesterday on whether to secede from North Sudan.

EARTH: OPEC and Oil: The Next 50 Years

Over the past five decades, OPEC has earned a reputation for being a powerful cartel that controls the world's oil production and prices - but there are limits to OPEC's influence and wealth. In fact, many OPEC countries face grave problems, which are to some extent the result of their oil-income dependence. EARTH examines OPEC's past, current and future place in this world. Will OPEC continue to control the planet's oil for the next 50 years?

EARTH: Trade Imbalance, America Exports Emissions to China

America has made great strides in recent years to reduce carbon emissions by increasing efficiency and turning to other, low or non-carbon energy sources. Meanwhile, carbon emissions in China have grown dramatically during that same time. EARTH looks at this disparity and asks the difficult questions about who is to blame when the coal China is burning is imported from "cleaner" countries and the emissions are produced to manufacture goods exported back to places with lower emissions.

AGI Announces New Year Publications Sale

EARTH: Greening the Friendly Skies

In light of global concerns about emissions and climate change, the aviation industry is cleaning up its act. The industry is reducing emissions, decreasing fuel use, increasing efficiency and developing new technologies to alter its environmental impacts. The November issue of EARTH magazine focuses on the changes to learn how the aviation industry is using synthetic fuels and engineering, and even altering common flight plans to keep up with changing protocols and dwindling resources.
