Brief description More than 3.7 billion years ago atmospheric greenhouse CO2 was sequestered into limestone sedimentary rocks deposited in ice-free oceans. Why then, with the 30-25 per cent cooler sun in those times, was our earth not frozen over? Solving this oldest climate problem, will give the deepest-time perspective to the earth's changing climate feedback loops.
