The researchers figured they could check that by studying how kids with autism process moving images.

'Dangerous Territory:' Carbon Dioxide Levels Reach Iconic High

Carbon dioxide readings at the Mauna Loa Observatory in Hawaii have reached what atmospheric scientist Ralph Keeling calls a "psychological threshold" of 400 parts per million.
