Approximately how many years ago were Earth's temperatures most similar to today's, according to the 160,000-year record?

Explanation:
In long-term climate records, scientists look for past times when global temperatures were similar to today to gauge how our current warming fits into natural patterns. In the 160,000-year temperature record, the time that most closely matches today is the last interglacial, about 125,000 years ago. During that interval, global temperatures were comparable to present-day levels, and ice sheets were smaller, leading to higher sea levels. That combination makes it the closest analog within this record. The other time points in the window represent cooler periods (like the glacial phase around 20,000 years ago) or different phases that aren’t as similar to today.
