CO2 makes up .04% of the earths atmosphere (thats 4/100 of 1%). Man is responsible for about 3% of the .04%
Yeah but if the atmosphere ever gets to 0.05%, every tree on the planet will spontaneously combust. And that 0.01% increase has 1000 times more heat capacity than the ocean, plus it will get stuck in the atmosphere because infrared radiation .(ie heat) does not penatrate the ocean surface further than a milimeter or two unlike short wave solar radiation which transfers energy directly from the sun all day every day into the tropical oceans hundreds of feet down which drives currents to moves that heat all around the world and up to the poles, but those trillions of joules of energy contained in a material with a huge specific heat just cant hold a candle to a 0.01% increase in atmospheric CO2. Dont even get me started on convection
Global Warming is nothing more than Pollution with US Taxpayers paying to get rid of it. Want to really tweak a climate alarmist? Tell him by planting more trees the CO2 will get converted to Oxygen. They cannot handle that.
