Using past data to predict whether 2020 will be the warmest on record

Enlarge / One interesting way to look at the world: the darker the red, the closer the correlation between local temperature and global mean. Blue areas tend to prefer contrarian temperatures.

Meteorologists run weather-forecast models to provide good predictions of weather conditions over the next few days. Climate scientists, on the other hand, run global climate models to project the impacts of climate-changing greenhouse gas emissions over the next few decades. In between these two activities is an interesting task that has proven more difficult than either: predicting global temperature over a few years.
