View Resource Global Climate Change: A Glance in the Rear View Mirror

This Geotimes article provides information regarding the inference of paleoclimate (global climate change) from proxy data such as ice core (oxygen isotope) records and biota found in deep sea sediments. The article discusses the history of proxy usage, the basis of current proxies, and gaps in our understanding of carbon/material cycling and climate records.

View Resource Garbage-Eating Geobacter

This Geotimes article highlights recent work done by Derek Lovley on the microbe Geobacter. The article discusses the ability of Geobacter to eat metal wastes as well as the prospect of using Geobacter as a microbial fuel cell. The web site also contains links to the Geotimes' home page, the American Geological Institute (AGI) home, and other useful AGI links.

View Resource Cave Formation: Biogeochemical Cycles

This video explores the role of biogeochemical cycles in the formation of caves. It discusses a radical new theory that identifies sulfuric acid as a cave-forming agent. The video, adapted from a NOVA broadcast, identifies the source of the sulfuric acid, which, unlike carbonic acid, the typical cave-forming agent, does not readily form in nature. The segment is 5 minutes and forty seconds in...

View Resource Cold Climate, Warm Climates: How Can We Tell Past Temperatures?

This brief National Aeronautics and Space Administration article provides general information about paleoclimatology (the study of past climate). Focusing on ice core data and foraminifera (shelled marine microorganisms) in deep sea sediments, the article provides a summary of how paleoclimate can be inferred.
