Honest question. If during the warmest periods ice melts all over the planet, wouldn't ice cores lack carbon measurements for those periods? I'd love an answer from someone with some expertise.
- ceejayoz 7y agoSure, but that hasn't happened for at least 2.7 million years. https://www.sciencemag.org/news/2017/08/record-shattering-27-million-year-old-ice-core-reveals-start-ice-ages https://www.sciencemag.org/news/2017/08/record-shattering-27...
- jcoffland 7y agoThat article says that the oldest ice in the core was 2.7 million years old. It actually mentions gaps in the record and ability to date ice only with a 100k year margin of error. This does not imply that we have a continuous record of carbon levels for the past 2.7M years.
