What is a climate anomaly?

A climate anomaly is the difference of a future climate compared to the present climate. We have provided four time period anomalies; Near Term (2020-2039), Mid-Term (2040-2059), End of Century (2080-2099), Last Decade (2090-2099) for our anomalies. The present day climate is computed from the 20th Century Experiment (1980-1999). We use a twenty-year average to compute our anomalies in order to filter out noise from the model and better see the climate signal.
