Volcanic Aerosols aren't the only in play short term. There is Solar and in addition to direct reflection of solar by aerosols there are indirect aerosol effects.
Including the Total Solar Irradiance (TSI) anomaly you get a bit messy combined TSI + Vol forcing that doesn't fit on the exit end of the Pinatubo period. With a lot of creative smoothing and adding some trend, the combination is likely to be a fair fit, but the error margin of the data is as large as the temperature anomaly. Notice the mean value line for TSI + Vol which may provide a clue how much the unknown trend may be ignoring the scale on the right axis for the moment.
Longer term there is a bigger can of worms with volcanic and prolonged solar forcing. Using the combined forcing as noted, the depths of the little ice age globally was likely between 1817 to 1825. Different regions have different response times, magnitudes and lags, but the northern hemisphere is generally more sensitive than the southern hemisphere and there is a definite difference in lag times. Recovery from the Little Ice Age, neglecting lags greater than ~8.5 years appears to have been completed around the late 1940s.
Enough for today.
