摘要：

We applied a newly established procedure to quantitatively estimate summer temperatures during two different time frames (the last 3 ka, the last 200 years) from selected fossil pollen records in northern Italy. The adopted procedure involved three steps: 1) the development of a specific calibration set (modern pollen data and site-specific climate data); 2) the application of numerical methods to the specific calibration set in order to create pollen-climate models based on the relationships between these variables; 3) the application of these models to fossil pollen records. The evaluation of pollen-climate calibration models and of the resulting past climate reconstructions is based on the comparison with instrumental series and with other independent climate proxies.
