Climate change rally draws large turnout

By Matt Owens February 17, 2013

Washington D.C. - A large crowd, possibly 30,000 people strong are marching in Washington D.C. today to protest climate change the keystone pipeline. Many climate scientists have said that using the Canadian tar sands oil - which the Keystone Pipeline would transport through the U.S. for international export - will equal "GAME OVER" for our climate.

Drums of all kinds including a large one carried by several people (just barely visible through the crowd in photo above) and small brass bands played as the protesters marched.

350.org, the Sierra Club, and countless other organizations helped organize and bring protesters to D.C. today.

Below are videos from just a few hours ago. For more photos, click here to see the Fairfax Climate Watch "signs of change image gallery.

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.

source

-------------------------

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

Highlighted Research

EdGCM
A research-grade climate model at your fingertips.
Hydrogen and Fuel Cells Research - Systems Analysis
Lots of papers on hydrogen...
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...
