A Tropical Plant’s Warmth Threshold Affirms Mid-Holocene Temps Were ‘7.7°C Higher Than Today’

A warmth-demanding plant can provide us with solid evidence of a much warmer than today Mid-Holocene climate.
Growth of the tropical aquatic plant 𝐶𝑒𝑟𝑎𝑡𝑜𝑝𝑡𝑒𝑟𝑖𝑠 ceases when air temperatures fall below 10°C.
A new study says that from about 8000 to 5000 years ago it was warm enough in winter that 𝐶𝑒𝑟𝑎𝑡𝑜𝑝𝑡𝑒𝑟𝑖𝑠 could grow at the 40°N latitude in northern China. Today its warmth threshold growth limit is ~34°N.
Scientists can therefore deduce the Mid-Holocene winter temperatures needed to have been “7.7°C higher than today” at that time.
