2000+ year graph of global temperature including so-called "Medieval Warm Period" (shaded in pink) and "Little Ice Age" (shaded in blue) - derived from graphic by Ed Hawkins.

Suggested caption:
Global average temperatures show that the Medieval Warm Period was not a planet-wide phenomenon, and that the Little Ice Age was not a distinct planet-wide time period but rather the end of a long temperature decline that preceded recent global warming.&lt;ref name=Hawkins_20200130&gt;{{cite web |last1=Hawkins |first1=Ed |title=2019 years |url=https://www.climate-lab-book.ac.uk/2020/2019-years/ |website=climate-lab-book.ac.uk |archiveurl=https://web.archive.org/web/20200202220240/https://www.climate-lab-book.ac.uk/2020/2019-years/ |archivedate=February 2, 2020 |date=January 30, 2020 |url-status=live }} ("The data show that the modern period is very different to what occurred in the past. The often quoted Medieval Warm Period and Little Ice Age are real phenomena, but small compared to the recent changes.")&lt;/ref&gt;
