Global Surface Temperature Anomalies Should Be Higher In 2016 Than 2015

This post confirms what most of us suspect based on the history of global surface temperature data responses to strong El Niño events. That is, if global surface temperatures respond similarly to past strong El Niños, the 2016 values should … Continue reading
