The global concentration of carbon dioxide in the atmosphere – the primary driver of recent climate change – has reached 400 parts per million (ppm) for the first time in recorded history, according to data from the Mauna Loa Observatory in Hawaii.

Since 1958, the Mauna Loa Observatory has been gathering data on how much carbon dioxide is in the atmosphere. Carbon dioxide has increased by about 24 percent since the beginning of this record. (Source: NOAA)

Of course 'everyone' knows  those pesky climate scientists are part of a vast, global conspiracy and not to be trusted - why, they even try to convince us that we live in a heliocentric universe, when any fool with eyes in his head can see that the Sun comes up in the East and goes down in the West and therefore must obviously rotate around the Earth.
