Global warming science facts from new research indicates that ENSO will not become a permanent feature as speculated by the IPCC's resident AGW alarmists - the massive climate phenomenon will remain variable
Read here. Climate alarmist scientists speculated that global warming from human CO2 emissions would somehow cause the El Niño/La Niña climate cycle to become stuck in the El Niño mode. This would be the proverbial "tipping point" potentially causing the infamous runaway warming.
Unfortunately for the alarmists, and fortunately for the rest of us, Earth's systems primarily operates in a negative feedback fashion, preventing runaway situations. In addition, Davies et al. confirmed that during past warming periods, ENSO did not become stuck in the El Nino mode.
"The authors write that "variations in the frequency and amplitude of the El Niño-Southern Oscillation (ENSO) recorded in both instrumental and paleoclimate archives have led to speculation that global warming may cause fundamental changes...More specifically, they state that there is speculation that "warmer climates may promote a permanent El Niño state...In a study designed to further explore this possibility...analyzed the latest Cretaceous laminated Marca Shale of California, which permits..."a seasonal-scale reconstruction of water column flux events and, hence, interannual paleoclimate variability," during what is known to have been a "past 'greenhouse' climate state."...In light of their recent findings, Davies et al. say there is "little support for the existence of a 'permanent El Niño'...that there was robust ENSO variability in past 'greenhouse' episodes and that future warming will be unlikely to promote a permanent El Niño state," which point they also emphasize in the final sentence of their abstract, where they say that their evidence for robust Late Cretaceous ENSO variability "does not support the theory of a 'permanent El Niño,'" [Andrew Davies, Alan E.S.
