2015 will easily be the hottest year in millennia...2015 will be more than 0.2°C hotter than 1998, despite having a slightly weaker El Niño warming influence. That temperature difference is the result of human-caused global warming. If we look at the temperature trends just for El Niño years, for La Niña years, and for neutral years, each has a trend of 0.15–0.17°C global surface warming per decade since the 1960s. The years during the mythical “pause” fall right along the long-term trend lines for each category (e.g. the blue points are consistently near the blue trend line). This tells us that the long-term global warming trend persists.
