CONTEXTS:
[001] Ice Core - this core is a record of precipitation from ~100kya.
[002] H2O - precipitation with a lower ration of oxygen-18 isotopes that falls at the poles is evidence of a warmer year.
[003] Mass Spectrometer - running frozen precipitation through mass spectrometer separates and counts ratio of O16 to O18.
[004] Funding - substantial government funding is required to fly drill team to poles, drill core, keep it refrigerated, and return to spectrometry lab.
[005] Climate Flux - the planet is about 5°C cooler (+/- 1°C) than it was 100,000 years ago.
