Greenhouse Gases: Seeing the Unseeable with 'Gas Finder' FLIR Cameras

(The CO2 we breathe out does not add to global warming, say scientists, since its part of the natural carbon cycle. Rather, they say it's the carbon long stored in the earth in the form of coal, oil and gas, that adds excess warming CO2 to the atmosphere when we burn it - along with the CO2 that escapes from rotting vegetable matter in deforestation and some agriculture.)

They showed us another FLIR video, shot by a team of researchers in the Arctic, with what looks like black smoke puffing out of a hole in the frozen sea surface.

Moments later, as seen in a color snapshot, they had set a match to the invisible methane leaking from natural deposits in the warming sea bed which the FLIR camera had made visible, and had what looked like a campfire directly on the ice - with no wood.

On a walk through their plant to see how FLIR cameras are made, we asked them if - given global negotiations to regulate carbon dioxide – if anyone has requested a CO2 camera for commercial use.

"No one's asked us for one," said Benson.

Not yet, but global negotiations aiming to make it finally no longer free to put emit CO2 into the air may soon have FLIR's full attention.
