This is the Darvaza Natural Gas Crater.
The Darvaza natural gas crater is located in the center of the Karakum desert in the Central Asian nation of Turkmenistan. The crater resulted from a Soviet natural gas exploration accident in the 1950's and has been burning ever since. The crater is approximately 60 meters in diameter and its depth is approximately 20 meters. When methane is burned it produces CO2 and water vapor in a ratio of 25%/75% since methane is composed of that ratio of carbon and hydrogen. This fire has been burning for nearly sixty years, so one is inclined to wonder how much CO2 it has released over that span, and whether it's the only such crater. While technically "manmade", the crater is none the less a natural phenomenon since an errant bolt of lightning could just as easily have caused it. Bear in mind that volconoes, and many other natural sources such as methane hydrates, release greenhouse gasses every second of every day in quantities that easily eclipse our total output of such gasses throughout the span of our use of carbon based fuels.
This begs a question: Why would anyone ever believe that we are the cause of global climate change? The only plausible reason would be that they stand to profit from others believing it too.
