Previously, we analyzed the claim by Democrats that global warming was being caused by American light bulbs.
As shown here, that claim is found to be without any empirical merit - essentially, pure anti-science rhetoric on the part of Democrats.
Next we take a look at the Democrats' claim that plastic bags are a major cause of global warming.
For many Democrats, the banning of plastic bags in their local communities has become a personal cause célèbre that represents a badge of honor in the fight against global warming.
But does the plastic bag "cause" have any scientific merit or is just more anti-science from quacks?
To the math. In the U.S. some 100 billion plastic bags are used each year. Yikes!
On average, it's been estimated that a plastic bag weighs 32.5 grams (for the record, a typical grocery store plastic bag weighs only 5 grams). And its been estimated that a plastic bag at the average weight represents about 200 grams of CO2 (when accounting for the plastic bag's production and eventual incineration).
As a result, via simple multiplication, those 100 billion plastic bags equal 20 trillion grams of CO2, which converts to 20 million metric tonnes of CO2.
Sooo.....what's the plastic bag impact on global warming from 20 million tonnes/year of CO2 over the next 20 years?
Well, it's squat, too. There is no warming impact, which makes the Democrats' claim more anti-science propaganda of the quackery sort.
Banning plastic bags due to their climate change impact is sheer nonsense, but banning them for other environmental reasons is a whole 'nuther issue.
The global warming impact calculation can be accomplished with the 'C3' simple estimator found here and just enter the CO2 tonnes amount desired. (Note: The image above is only a replica of the real tool.)
For comparison purposes, the 'C3' estimator replica above also reveals what would happen to "global warming" if the entire U.S. economy shuts down for one year, eliminating some 5.8 billion tonnes of CO2 emissions from fossil fuel combustion - again, it's a global warming nothing-burger.
