Extreme temperatures in Southeast Asia caused by El Niño and worsened by global warming

by K. Thirumalai et al., June 6, 2017, in Nature Communication


In April 2016, southeast Asia experienced surface air temperatures (SATs) that surpassed national records, exacerbated energy consumption, disrupted agriculture and caused severe human discomfort. Here we show using observations and an ensemble of global warming simulations the combined impact of the El Niño/Southern Oscillation (ENSO) phenomenon and long-term warming on regional SAT extremes. We find a robust relationship between ENSO and southeast Asian SATs wherein virtually all April extremes occur during El Niño years.

Satellite Data: Post El Niño Global Surface Cooling Continues… Pause Extends To 20 Years

by P. Gosselin, April 12, 2017


Critical German climate site wobleibtdieererwaermung.de (WBDE) reports that the earth’s surface is cooling, and presents the latest chart from NCEP. As of April 11, the measured global values continue to decline (black curve) as do the computed values for April 18.

The time-delayed post El Niño cooling is now showing up in the UAH and RSS satellite data.

Further proof El Niños are fueled by deep-sea geological heat flow

Origine géothermique de El Nino : quelques évidences?

… Based on this information, it is most likely these eruptive El Niño heat pulses are the result of flow from the various individual components of a giant Solomon Island Area seafloor circulating system. Individual geological components include fractured rock layers, hydrothermal vents, seafloor volcanoes, and open faults. The circulating system is activated by upward movement of deep magma chambers located beneath the Solomon Island area. This movement triggers a high-magnitude earthquake swarm, which in turn activates the seafloor circulating system….
