Stratosphere 1980-2025

The 45-year record exhibits a falling temperature trend of -0.235 ⁰C per decade.

The impact on stratospheric temperatures of volcanoes like El Chicon and Mount Piatubo show a big rise followed by a more gentle fall over about three years.

Since 1995 there have been no significant volcanoes.

Since 1995, stratospheric temperature has show a much shallower slope in the fall - to about half of the pre-1995 fall rate.

The 30-year average and the decadal average are converging to similar fall rates.

Simple Exponential Smoothing

All the curves are showing recent resumption of faster temperature fall-rates.
