Global Temperatures Warming as Expected by Models

HT to Michael Mann for flagging, and explaining this.
New research helps answer the white knuckle panic that some climate-watchers have expressed about a recent dramatic acceleration in global temperatures.
That said, some pretty good scientists have expressed concerns about the larger than expected IMPACTS of the expected temperature rise.

Nature – 2023 temperatures reflect steady global warming and internal sea surface temperature variability:

A common question is whether the 2023 Global Surface Temperature Anomaly (GSTA) was record-breaking by a record margin. In Fig. 1, we test this by calculating the margin for each record-breaking year, for four major temperature reconstructions (HadCRUT5, NOAA, Berkeley Earth, and GISTEMP). Most GSTA records since 1970 were set by margins of around 0.05 °C, while in El Niño years, margins of up to 0.15 °C have been recorded. Results are very similar for the four reconstructions. For 2023, the margins were indeed record high (0.17 °C) in two series (HadCRUT5 and BEST), while for the others it was on par with other recent El Niño years. This is consistent with expectations for a situation of strong but steady global warming, modulated by (ENSO-dominated) internal variability. From the observations over the last 50 years, there is therefore no immediate cause to claim that record margins are changing with time, which is, in turn, consistent with a broadly steady rate of global surface warming.

  1. Am I being stupid or does that make no sense. It would be logical if El Ninos were evenly spaced but super El Ninos were 1983, 1998 and 2015. With 15 and 17 years of additional heating it was no wonder that previous El Ninos could reach margins in the order of 0.15degC. 2023 wasn’t even a super El-Nino and only 8 years after a previous super El Nino. How does the logic in the provided text stand up against the charge that similar scenarios are not being compared because the time-frame between El-Ninos is not the same?


  2. I don’t get it.
    The rate of heating should be proportional to the amount of GHG in the atmosphere at any given time (the setting of the knob on the stove) ±ENSO, right?

    Atmospheric trends in both CO2 and CH4 are still going up.
