In a\u00a0new study<\/a>, scientists use the new \u201costracod-clumped isotope thermometer\u201d to reconstruct a much warmer Late Pleistocene\/Early Holocene Mediterranean climate.<\/strong><\/p>\n\n\n\n

Today\u2019s average summer and winter temperatures are 22\u00b0C (21.4\u00b0C) and 8\u00b0C, respectively, at Central Italy\u2019s Lake Trasimeno.<\/p>\n\n\n\n

Around 11,000-12,000 years ago, when CO2 hovered in the 220-230 ppm range, summer temperatures averaged 25\u00b0C, sometimes rising to 27\u00b0C. This is at least 3\u00b0C warmer than today.<\/p>\n\n\n\n

As CO2 concentrations rose into the Early Holocene (9,000 to 10,000 years ago), the ostacod-clumped isotope thermometer indicates summer temperatures at this location dipped to 23\u00b0C (22.5 to 23.2\u00b0C).<\/p>\n\n\n\n

During this same period winter temperatures averaged 12\u00b0C (11.8\u00b0C), which is \u201c4\u00b0C warmer than today.\u201d<\/p>\n\n\n\n
