Highlighted Research

  • Wind Power
    Especially see "Geographical and seasonal variability of the global "practical" wind resource (Applied Geography, 2013)."
  • "Global Warming: Understanding the Forecast" by David Archer
    Plug and Play Models - Not exactly typical research, more of an interactive tool, and you really should know the assumptions of the models...but still even if you don't, this is valuable...

Convert carbon dioxide (CO2) weight to carbon (C) weight


CO2/3.67 = 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
