The atmosphere is bigger than you think

Reduce your carbon footprint and save the planet!

Q: How much carbon should I remove from my footprint?
A: 1,767,250,000,000 metric tonnes per Centigrade degree of global average temperature change, attributing all temperature increase over the past 150 years to CO2 emissions. (Your mileage may vary, depending on whether you think the sun may somehow affect Earth's temperature, you outrageous radical). One point seven six seven quadrillion tonnes.

Put that into perspective:
  • A North American household contributes 24 tonnes per year of CO2
  • US emissions are 6,000,000,000 tonnes per year, total. Eliminate those emissions and the effect on temperature is about 3 thousandths of a Centigrade degree.
Here in Canada, we could divide that number by ten. Shut down every CO2 source for a year, save 3 ten thousandths of a degree. Wow.

So let's keep asking people who want to save us all from whatever terrifies them "what effect will it have on temperatures?" If the answer is a number that is detectable in real life, it is wrong.

Read the analysis here on World Climate Report. The various info sources are either US government stats or associated with Al Gore, in case you were wondering about "denier" "bias".

I use compact fluorescent bulbs to save money. Saving the planet? The planet will take care of itself.
