CO2 Instrumentation into Space

Nasa has launched a mission dedicated to measuring carbon dioxide (CO2) from space.

The Orbiting Carbon Observatory-2 (OCO-2) will help pinpoint the key locations on the Earth’s surface where the gas is being emitted and absorbed.

Its key objective is to trace the global geographic distribution of CO2 in the atmosphere – measuring its presence down through the column of air to the planet’s surface.

This should give scientists a better understanding of how the greenhouse gas cycles through the Earth system, influencing the climate.

Uncertain ‘sinks’

Humans are currently adding nearly 40 billion tonnes of carbon dioxide to the atmosphere every year, principally from the burning of fossil fuels.

Only about half of this sum stays in the atmosphere, where it drives warming.

About half of the other half is absorbed into the ocean, with the remainder pulled down into land “sinks”.

Exactly where, though, is highly uncertain.

I’d bet a few dollars that the vast kudzu jungles across the American south will be one of the great sinks…
