  <dc:description>&lt;p&gt;&lt;span&gt;The increase in atmospheric CO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;levels during the last deglaciation was comparable in magnitude to the recent historical increase. However, global CO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;budgets for these changes reflect fundamental differences in rates and in sources and sinks. The modern oceans are a rapid net CO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;sink, whereas the oceans were a gradual source during the deglaciation. Unidentified terrestrial CO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;sinks are important uncertainties in both the deglacial and recent CO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;budgets. The deglacial CO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;budget represents a complexity of long-term dynamic behavior that is not adequately addressed by current models used to forecast future atmospheric CO&lt;/span&gt;&lt;sub&gt;2&lt;/sub&gt;&lt;span&gt;&amp;nbsp;levels.&lt;/span&gt;&lt;/p&gt;</dc:description>
