Operation World — missions and the Earth and environmental sciences

One of the most significant influences that directed me into missionary service (my family served with ReachGlobal---the international mission of the Evangelical Free Church of America---from 2002 to 2008) was when we purchased a copy of Operation World back in the early days of our marriage. This book is a day-by-day prayer guide to the …

Pleistocene Park

From Yahoo! News/AP -- One scientist's hobby: recreating the ice age CHERSKY, Russia – Wild horses have returned to northern Siberia. So have musk oxen, hairy beasts that once shared this icy land with woolly mammoths and saber-toothed cats. Moose and reindeer are here, and may one day be joined by Canadian bison and deer. …

Book Review: Beyond Creation Science (part 2)

In part one of my book review of Beyond Creation Science by Timothy Martin and Jeffrey Vaughn, I stated that the authors succeeded admirably in one of their objectives, which was to present a Biblical case against young-Earth creationism, with its 6000-year old Earth and global flood. Their second, and perhaps primary, objective was to …

Book Review: Beyond Creation Science (part 1)

Two popular topics among Evangelical Christians for the past several decades have been origins---especially young-Earth creationism---and dispensational end-times eschatology (eschatology is the doctrine of the last things, including the return of Christ and the final judgment). Young-earth creationism has certainly been the prevailing dogma in Evangelical Christian education and in many churches and Christian colleges. …

A cheaper way to get humans to Mars: One-way tickets

NASA's Astrobiology Magazine has the text of a presentation given by physicist Paul Davies: A One-way Ticket to Mars. The greatest expense in sending a group of astronauts to Mars is actually getting them back to Earth. Davies estimates that we may be able to save up to 80% of the costs by sending a …

The Earth has a future

This item was originally posted in June 2006. I have added it to my blog recycling program. Because I have new readers of The GeoChristian, I will occasionally go back and re-use some of my favorite blog entries (with some editing). Additionally, this is being submitted to the January 2009 Accretionary Wedge Geoscience Blog Carnival, …

Shift Happens — The world is going to change a lot in the near future

Technological changes in our society tend to be exponential rather than linear. Some examples of this include: The density of transistors on integrated chips doubles every 24 months. Hard drive capacity increases about 40% per year (do you remember when that 20 MB hard drive seemed huge?) Computer RAM has gone from kilobytes in the …

The Earth Has a Future

We usually think of the science of geology as being about the past: geologists often reconstruct events that happened thousands, millions, or even billions of years in the past. Sometimes geologists are called upon to project into the future as well. Examples of this include earthquake prediction and finding sites for long-term (>10,000 years) storage …
