While rising carbon dioxide concentrations in the air can be beneficial for plants, it is also the chief culprit of climate change. The gas, which traps heat in Earth’s atmosphere, has been increasing since the industrial age due to the burning of oil, gas, coal and wood for energy and is continuing to reach concentrations not seen in at least 500,000 years.
How convenient for the IPCC WG1AR5 to NOT consider water vapor as a forcing, thus leading NASA to make such silly statements as above.

Maybe by cutting down huge swaths of forests, plowing the land, or covering it with pavement and cities we have fundamentally altered the much, much larger natural carbon cycle.
In the past 150 years humans have gone from using 4% of the lands surface to using 40% of the land surface, so to assume this has minimal effect is naïve.
Or maybe by exterminating most of the plankton eating great wales of the ocean we have fundamentally altered the natural carbon cycle.
Or maybe the warming of the planet since the end of the Little Ice Age has fundamentally altered the natural carbon cycle.
No one really knows the answer to these basic questions, beyond the accuracy of the proverbial WAG. So to assume that cutting emissions will cut CO2 remains at this time just an assumption.
