evidence: 01:21 Reassessing Earth’s climate over the past 24,000 years The ~20,000 year period from the Last Glacial Maximum to the pre-industrial era saw huge changes to the Earth’s climate. But characterising how temperatures changed during this time has been difficult, with different methods producing different results. Now, a team have combined two techniques, which they hope will provide new insights into the past, and future, of Earth’s climate. [...] This work provides a new take on changes to the Earth’s temperature over the last 24,000 years. And the results are likely to cause some debate in the field. For example, about 9,000 years ago, it suggests a small but consistent warming in global average temperatures up to the pre-industrial era, which was not shown in other proxy-only methods, including one Shaun was involved in, which suggested there was cooling during this time. For Shaun, though, this new paper doesn’t represent a conclusion to debates like this, rather it’s the start of a new way of piecing together past temperatures.
