The annual anomaly of the global average surface tem-perature for 2012 was the eighth highest on record at +0.14°C above the 1981 – 2010 baseline.
Monitoring changes in temperature records on a decadal to centennial scale worldwide is of primary importance in ensuring scientifically sound diagnostics and understand-ing of the state of the climate. In its role as one of the world’s leading climate centers, the Japan Meteorological Agency (JMA) provides global mean surface temperature data (i.e., combined averages of near-surface air tempera-tures over land and sea surface temperatures) on a monthly, seasonal and annual basis, thereby helping to raise pub-lic awareness of global warming development. The annual global average surface temperature anomaly for 2012 was +0.14°C with the 1981 – 2010 average as a baseline. This ranks as the eighth highest figure since 1891 – the earliest year of JMA’s global temperature anomaly records. Warm temperature anomalies were noticeable especially around North America, from western Russia through to the Mediterranean, and over the Indian Ocean and the central part of the North Pacific Ocean. The average temperature over land areas alone was the sixth highest on record. >> More
