Off balance: the CO2 and sea level seesaw – An interview with Dr Gavin Foster « Descent into the Icehouse

Off balance: the CO2 and sea level seesaw – An interview with Dr Gavin Foster « Descent into the Icehouse | Sustain Our Earth | Scoop.it

The study “Relationship between sea level and climate forcing by CO2 on geological timescales” by Dr Gavin Foster and Professor Eelco Rohling which was this week published in the  Proceedings of the National Academy of Sciences  had quite an impact on the science websites and blogs.

 

In an interview in Katy Edgington (ScienceOmega.com), Gavin “expounded on the link between CO2 and the seas, and how the correlation exhibited in this study could influence our forecasts for the future.

“The main advantage of looking at the geological past, and what makes it worthwhile, is that it represents a reality – a state which we can be sure the Earth system once occupied,” explained Dr Foster. “It inherently includes all feedbacks involved in the system whether we currently know about them or not; this is not the case with modelling, of course, which draws directly on the state of our current knowledge.”
