why did they stop at just looking back 24K years?
>In between ice ages, some lesser peaks of temperature have occurred a number of times, especially around 125,000 years ago.
>At this time, temperatures may have been about 1°C to 2°C degrees warmer than today.
>Sea level was 5 to 8 metres higher than today – a rise sufficient to inundate most of the world’s coastal cities.
>This peak was triggered by the orbital cycles.

- beowulfey 5y agoThis is a great question. You should ask the principle scientist of the study, Chris Poulsen. He has a twitter account that you can reach out to him through. This is not my field, but my guess would be that 24,000 years ago was chosen because it corresponds to the Last Glacial Maximum. The obvious reason is that it represents the lowest global temperature within a timeframe of normal human activity, and was a recent major turning point of the global climate. Beyond that, I'm not sure why the Last Glacial Maximum was specifically chosen as the starting point but I'm sure someone more versed in climatology may be able to comment on the significance of it.
