I really can't believe this!
I've re-read it several times!
Scientific American states in this link:
How Much Is Too Much?: Estimating Greenhouse Gas Emissions
Since 1750 humanity has added 520 billion metric tons of greenhouse gases to the atmosphere and we're on pace to add that much again within 40 years—a scenario that is likely to result in catastrophic climate change.
YET here is another "Scientific" source:
A short history of carbon emissions and sinks
Skeptical Science a biased defender of Global Warming fallacies...
"Since 1750 the human race has been responsible for roughly 2,000 gigatonnes of carbon dioxide emissions."
The tonne (
i/tÊŒn/) (British and SI; SI symbol: t) or metric ton (in the United States) is a non-SImetric unit of mass equal to 1,000 kilograms;[1][2][3][4] or one megagram (Mg); it is equivalent to approximately 2,204.6pounds,[5]1.10 short tons (US) or 0.984 long tons (imperial). Although not part of the SI per se, the tonne is "accepted for use with" SI units and prefixes by the International Committee for Weights and Measures, along with several other units like the bar, litre and day.
Tonne - Wikipedia, the free encyclopedia
A "gigatonne" is 1 billion tons right.
2,000 gigatonnes would be 2,000 times 1 billion (1,000,000,000) or 2 trillion tons!
Folks WHICH is it????
Has humanity since 1750 pumped out 520 billion metric tons or 2 trillion metric tons???
WHICH IS IT from these two respected and revered "Scientific" sources??? Who is right???
