When we look at the more recent wintertime temperature trend in Greta Thunberg’s Sweden, we can only conclude that nothing really alarming is happening. The winters there haven’t warmed significantly, if at all, since 1988.
The Japan Meteorological Agency (JMA) has released the Sweden mean temperature data for February, 2022, which also means we can look at the latest winter seasonal trends.
First we look at the February trends from 5 stations in Sweden, for which the JMA has enough data to allow adequate plotting. since 1988:
February mean temperature trends have fallen at 4 of the 5 stations since 1988; No real warming trend to speak of.
Winter temperature trend
But February is only a relative short 4-week period, so more interesting would be to examine the Dec-Jan-Feb wintertime trend using the (unaltered) JMA data. Global warming would tell us this would have to be clearly upward. But:
Unfortunately some of the JMA datasets have been a bit fragmented, but still sufficient to give us an idea of what’s happening.
Three of five stations in Sweden have seen no warming and two stations have seen modest warming. Taken altogether there’s nothing worrisome at all happening in the wintertime in Sweden.
This of course will not mean that Greta Thunberg will be coping better with her climate anxiety.
