Do you water your lawn?

You know, to keep your grass green.

Global warming is caused by gases in the air which are denser than the air.

That includes water vapor homeowners introduce into the air when they water their lawns.

1) Both CO2 and water vapor (H2O) are denser than air. The ratio of water vapor density to CO2 density is 0.436 at Normal Temperature and Pressure (NTP).
2) That number (above) can be looked up in engineering converson tables for gases.
3) One gallon of gasoline will produce about 20 lbs of CO2, a global warming gas (which can be easily calculated from complete oxidation of gasoline molecules).
4) One gallon of water weighs 8.34 lbs. When that water evaporates into the air, it too will cause global warming.
5) The ratio between the two weights (from items 3 and 4 above), 20 lbs and 8.34 lbs, is 0.417 (almost equal to the 0.436 mentioned above -- that's a good thing as there is no disagreement).

Humans Initiate Global Warming -- 6,000 BC:
Irrigation (the diversion of water for the purpose of farming) began at about the same time in Egypt and Mesopotamia (present day Iraq and Iran) using the water of the flooding Nile or Tigris/Euphrates rivers. The flood waters, which occurred July through December, were diverted to fields for 40 to 60 days.

Conclusion: The person providing the daily water usage data at his typical city home (but having a somewhat larger than normal yard) caused as much global warming every day during a 6-month period on his medium-sized lot during 2016 as a person can produce by burning 254 gallons of gasoline every day.

In other words, it is the redistribution of water by humans that is causing global warming, not the burning of fossil fuels.

Now guess how much global warming the city parks and the farmers are causing with all their irrigation.
