Climate Change Sources

Twitter, I hope you appreciate that I did this before my daily caffeine ritual.

On a more serious note, I’ve focused on articles that can be freely accessed. Some of these even have PDFs associated with them. Many have additional links (especially NASA and Youtube). Climate change is a rather messy, multidisciplinary topic so if you want clarification for any concepts and terminology, I’ve supplied additional sources.

Oxygen Isotopes

(Above: The Atmosphere by Lutgens and Tarbuck, 1998 by Prentice-Hall, Inc)

Determining Past Climate Change – Oxygen Isotopes

  • normal oxygen contains 8 protons, 8 neutrons (O16)
  • a small fraction (one in a thousand) of oxygen atoms contain 8 protons, 10 neutrons (O18)
    • this is an isotope of oxygen and is heavier than O16
  • O16 will evaporate more readily than O18 since it is lighter
  • Hence, during a warm period, the relative amount of O18 will increase in the ocean waters since more of the O16 is evaporating
  • Hence, looking at the ratio of O16 to O18 in the past can give clues about global temperatures.
  • Ice cores from glaciers can also give you similar information

Sex and Sexism in Space

Science fiction can act as a mirror for our society. Sometimes the reflection isn’t flattering. Take, for instance, the common trope of hooking up with hot anthropomorphic aliens. Now this wouldn’t irritate me in and of itself (or else Star Trek would’ve given me an aneurysm), but it always seems to cater to the straight, typically male audience who turn around and say “diverse” characters aren’t realistic.

I can hear you groaning from here. Oh, Christ. Not another SJW diatribe.

Well, no. Not quite. To paraphrase movieverse Mark Watney: “I’m gonna science the shit out of this.”
