Next time you're asked, "How much global warming is due to humans?", you can honestly say, "about 220%". That's right - 220%!

How so? Because on a 100 year time scale, the only major warmers are greenhouse gases, the main driving gas being CO2 (H2O is also major, but, being entirely passive, is not a driver).

Meanwhile, each year Earth manages to absorb 55% of the man-made CO2. So, the 45% that remains airborne is what's been raising atmospheric CO2 (by 2.1 parts per million by volume each year, or 43% since 1850). So, the man-made contribution to the main global warming driver is 220% or more than twice as much as what stays in our air.

What this really means is that humans are entirely responsible for ALL the global warming in the modern era. and then some.

Remember this when some skeptic questions man's contribution to global warming.
