Prequel to Chasing Ice - an hour long NOVA program
Posted by Matt Owens March 19, 2013
This is definitely worth seeing, even if you've already seen the movie!
Watch Extreme Ice on PBS. See more from NOVA.
A Radical Plan - ideas for sustainability, walkability, and livability.
Take Action - links to action groups.
Sea Level Rise - a bottom-line summary, plus links to posts.

Convert carbon dioxide (CO2) weight to carbon (C) weight
-------------------------
CO2/3.67 = C
or:
CO2 x 0.2727 = C
-------------------------
ex: 40 GtCO2 ≈ 10.9 GtC
-------------------------
1 Gt (Gigatonne) = 1 billion tonnes
1 tonne = 1,000 kg
-------------------------
Also: 1 Pg = 1 Gt
-------------------------
1 Pg (Petagram) = 1 quadrillion grams
-------------------------
Soil specialists tend to use Pg, as they are used to working with gram units per square meter of soil area. Atmospheric specialists tend to use Gt.
Convert carbon emissions to ppm atmospheric CO2
-------------------------
GtC/2.12 = ppm
To convert emissions of carbon to atmospheric ppm CO2, carbon sinks must be taken into account.
So far, terrestrial and oceanic sinks have taken up about 50% of CO2.
-------------------------
ex: 40 GtCO2 emissions ≈ 10.9 GtC
10.9 GtC/2.12 ≈ 5.14 ppm CO2 before accounting for sinks
5.14 ppm CO2 x 0.5 ≈ 2.57 ppm CO2 after accounting for sinks
