Which of the below statements related to these graphs is FALSE? It is dustiest (and therefore driest) during cold glacial periods. Temperature and carbon dioxide records match very well – when carbon dioxide is higher, temperature is also higher. As we move forward in time, temperatures follow a pattern where there is gradual warming into an interglacial but then very abrupt, dramatic cooling to the next glacial. Warmer interglacial periods occur every 100,000 years on this graph.
