2023’s ‘Record Temperatures’ Were Not Driven by CO2 Emissions, New Science Paper Finds

by Chris Morrison | The Daily Skeptic

It is becoming increasingly obvious to serious climate scientists that sudden changes in temperature and weather cannot be directly attributed to any long-term effect of warming caused by human-produced ‘greenhouse’ gases. Suggestions to the contrary are best left to climate comedy-turn Jim ‘jail the deniers’ Dale and the guided hands writing most mainstream media copy. Last year saw a large spike upwards in global ‘hottest year ever’ temperatures and alarmism went into overdrive. But a recent paper published by the EU weather service Copernicus shows that the warming spike was driven by a strong, naturally occurring El Niño oscillation. Furthermore, the 0.29°C spike is not unprecedented in the observation record since a slightly larger rise occurred in 1976-77.

The Copernicus paper published in the journal Atmospheric Chemistry and Physics is of particular interest because it makes a connection between a strong El Niño developing across the southern hemisphere after a prolonged La Niña. El Niño is the positive phase of the ENSO natural climate variation, while La Niña, which tends to lower temperatures, is the corresponding negative episode. In the years around 2023 and 1976, a strong El Niñooccurred after a prolonged La Niña phase. In 1976 the spike was even higher at a reported 0.31°C.

The work published through Copernicus is firmly in the mainstream, so the seemingly obligatory reference is made to the unproven suggestion that global temperatures since 1950 have been rising “principally due to human activities”… Read Full Article >
