As today is St. Patricks Day, it’s a good time to look at Ireland’s annual mean temperatures over the recent decades.
As we recall, global cooling was the scare of the 1970s before global warming became the scare in the 1980s. So since the 1980s, a fair amount of warming must have taken place, right?
Ireland has been cooling
Looking at 6 stations (half at airports!) across the emerald island, we see in fact there’s been a notable cooling over the past 25 years, since 1994:
Obviously global warming never made it to the island. And yes, it’s mysterious how the Irish media still continue to hysterically warn about warming when temperatures in fact have been falling instead of rising.
The source of the (untampered) plotted data is the Japan Meteorology Agency (JMA). The six datasets were selected because of their data completeness – only a few months of data are missing.
30 years of cooling
The non-warming trend of the 6 Irish stations goes back to 1986, i.e. more than 30 years:
There has not been any warming since 1986, thus surpassing the 30-year mean that is defined as “climate”. We see a similar trend in my home country of Japan.
Cooling since Hansen’s 1988 warnings of warming
When did the Irish cooldown start? After the cold years of 1986 and 1987, the temperature spiked more than 3°C in a single year to 11.5°C in 1988, the year that Dr. James Hansen told the world before Congress that the planet was heating and would heat up to unbearable conditions within 30 years.
Plotting the data since Dr. Hansen’s dire warnings in 1988, we see that Ireland in fact has cooled off:
If the Irish can celebrate anything this St. Patrick’s Day, it is the fact that they won’t need to worry about overheating anytime soon.
Happy St. Patrick’s day everyone.
