Repeat Photography & Global Warming

Repeat photography is pretty straight-forward: multiple pictures taken from the same spot years apart.   The technique is useful to determine and document changes in climate and human impact on the environment.   Wired Magazine has a fascinating series of repeat photos taken by the US Geologic Survey that show restored archeological sites, rivers that have moved, and glaciers that have all but vanished.   

Global warming anyone?  

Climate Change Links

Added some new links to climate change articles. One is from the BBC and consists of a slideshow on how residents are adapting to climate changes (flooding) in Vietnam. Another is an article from Discover Magazine investigating whether the core of the Antarctic icepack is melting.

I have run into an annoying number of people lately who still don't "believe" that global warming is happening, or that humans are largely responsible for it. I doubt that there's any way to convince them to read the research, since they've apparently already passed up that opportunity numerous times. The information is out there; for some reason, some people would rather dismiss it as some sort of "liberal conspiracy" or a disguised attack on "our liberties."

Regardless of whether you accept that the human dependency on fossil fuels since the dawn of the Industrial Revolution is the culprit, it seems to me that denying that there is a problem is just plain nonsense. Whatever is causing the temperature increase, it's effecting us and our world, and in some very scary ways. Doing nothing would not seem to be an option. Science tells us that there have been at least 5 major extinctions in the past. The difference now is that humans are aware (allegedly) of their surroundings, their impact on the environment, and have some ability to change how they interact with the environment. The dinosaurs weren't and didn't.

I've decided to start collecting links to various online resources that cover the subject of global warming, climate change, or whatever other label may apply. I'm putting the links in a section at the bottom of the blog titled "Links About Climate Change - Especially For Those Who Don't "Believe" In Global Warming." Hopefully, it may be useful to those who are interested enough to read up on the topic. I don't plan to include any technical articles, because they tend to be pretty obtuse and hard to follow. I'd welcome comments as well as other links you may come across.

The first few links are from some Marketplace.org radio broadcasts and Discover Magazine. They present specific examples of how fossil fuels have raised temperatures with unexpected results and how CO2 (from fossil fuels) may be damaging our oceans more than anyone foresaw.
