To better constrain the response of Earth’s climate system to continuing emissions, it is essential to turn to the past. A key advance would be to understand the transition in Earth’s climate response to changes in orbital forcing during the 'mid- Pleistocene transition' (900 to 1200 thousand years ago) and in particular the role of greenhouse gases and other forcing factors. Unraveling such key linkages between the carbon cycle, ice sheets, atmosphere and ocean behavior is vital for society to better design effective mitigation and adaptation strategies. Only ice cores contain the unique and quantitative information about past climate forcing and atmospheric responses. But the ice providing essential evidence about past mechanisms of climate change more than 1 Ma ago required for our understanding of these changes has not been yet found.
