Temperature and CO2 concentration in the atmosphere over the past 400 000 years | GRID-Arendal - Pub 2. Over the last 400,000 years the Earth's climate has been unstable, with very significant temperature changes, going from a warm climate to an ice age in as rapidly as a few decades. These rapid changes suggest that climate may be quite sensitive to int
