Warming Oceans = More CO2
“Scientists noted that emissions tend to rise more quickly during an El Niño weather pattern. The El Niño phenomenon, which was unusually strong in 2015-16, warms the Pacific Ocean, bringing heavy rains and droughts to different parts of the world. Scientists say the increase in sea surface temperatures that occurs during an El Niño causes less carbon dioxide to be dissolved in the oceans and, as a result, more accumulates in the atmosphere.

Stephen A. Montzka, a NOAA research chemist who worked on the index, said the spike between 2015 and 2016 — the largest incremental increase in greenhouse gases since 1988 — was largely caused by El Niño. The jump between 1987 and 1988, which came in at a slightly higher 2.8 percent, was also linked to an El Niño.”
