Global temperatures spiked during the last half of 2015 as a result of the strong El Nino and were still at very high levels relative-to-normal as recently as last month. In addition, global sea ice appeared to be impacted by El Nino as it took a steep dive during much of 2015 and remained at well below-normal levels going into this year. In the past couple of months, however, El Nino has begun to collapse and will likely flip to a moderate or strong La Nina (colder-than-normal water) by later this year.
