“…by about 10 kyr ago, regional MST values consistently approached or exceeded today’s value of about 23°C” – Baxter et al., 2023

According to a new temperature reconstruction published in Nature, the Horn of Africa and “global tropics as a whole” were “1.6°C warmer than today” throughout the Early and Middle Holocene. This is “consistent with compilations from the global tropics.”

This region’s mean surface temperature (MST), 23°C, is nearly the coldest in the last 10,000 years. It was as warm or warmer than today not only 10,000 years ago, but also from about 55,000 to 30,000 years ago, when Earth was experiencing glacial conditions and CO2 concentrations were said to be below 200 ppm.
